#GSocketClient is a lightweight high-level utility class for connecting to a network host using a connection oriented socket type.

You create a #GSocketClient object, set any options you want, and then call a sync or async connect operation, which returns a #GSocketConnection subclass on success.

The type of the #GSocketConnection object returned depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a #GTcpConnection.

As #GSocketClient is a lightweight object, you don't need to cache it. You can just create a new one any time you need one.

The proxy resolver to use

timeout: number
tls: boolean
tlsValidationFlags: TlsCertificateFlags

The TLS validation flags used when creating TLS connections. The default value is %G_TLS_CERTIFICATE_VALIDATE_ALL.

GLib guarantees that if certificate verification fails, at least one flag will be set, but it does not guarantee that all possible flags will be set. Accordingly, you may not safely decide to ignore any particular type of error. For example, it would be incorrect to mask %G_TLS_CERTIFICATE_EXPIRED if you want to allow expired certificates, because this could potentially be the only error flag set even if other problems exist with the certificate. Therefore, there is no safe way to use this property. This is not a horrible problem, though, because you should not be attempting to ignore validation errors anyway. If you really must ignore TLS certificate errors, connect to the #GSocketClient::event signal, wait for it to be emitted with %G_SOCKET_CLIENT_TLS_HANDSHAKING, and use that to connect to #GTlsConnection::accept-certificate.

name: string

Methods

  • addApplicationProxy(protocol: string): void
  • Enable proxy protocols to be handled by the application. When the indicated proxy protocol is returned by the #GProxyResolver, #GSocketClient will consider this protocol as supported but will not try to find a #GProxy instance to handle handshaking. The application must check for this case by calling g_socket_connection_get_remote_address() on the returned #GSocketConnection, and seeing if it's a #GProxyAddress of the appropriate type, to determine whether or not it needs to handle the proxy handshaking itself.

    This should be used for proxy protocols that are dialects of another protocol such as HTTP proxy. It also allows cohabitation of proxy protocols that are reused between protocols. A good example is HTTP. It can be used to proxy HTTP, FTP and Gopher and can also be use as generic socket proxy through the HTTP CONNECT method.

    When the proxy is detected as being an application proxy, TLS handshake will be skipped. This is required to let the application do the proxy specific handshake.

    Parameters

    • protocol: string

      The proxy protocol

    Returns void

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • This is the asynchronous version of g_socket_client_connect().

    You may wish to prefer the asynchronous version even in synchronous command line programs because, since 2.60, it implements RFC 8305 "Happy Eyeballs" recommendations to work around long connection timeouts in networks where IPv6 is broken by performing an IPv4 connection simultaneously without waiting for IPv6 to time out, which is not supported by the synchronous call. (This is not an API guarantee, and may change in the future.)

    When the operation is finished callback will be called. You can then call g_socket_client_connect_finish() to get the result of the operation.

    Parameters

    Returns void

  • This is a helper function for g_socket_client_connect().

    Attempts to create a TCP connection to the named host.

    host_and_port may be in any of a number of recognized formats; an IPv6 address, an IPv4 address, or a domain name (in which case a DNS lookup is performed). Quoting with [] is supported for all address types. A port override may be specified in the usual way with a colon. Ports may be given as decimal numbers or symbolic names (in which case an /etc/services lookup is performed).

    If no port override is given in host_and_port then default_port will be used as the port number to connect to.

    In general, host_and_port is expected to be provided by the user (allowing them to give the hostname, and a port override if necessary) and default_port is expected to be provided by the application.

    In the case that an IP address is given, a single connection attempt is made. In the case that a name is given, multiple connection attempts may be made, in turn and according to the number of address records in DNS, until a connection succeeds.

    Upon a successful connection, a new #GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

    In the event of any failure (DNS error, service not found, no hosts connectable) %NULL is returned and error (if non-%NULL) is set accordingly.

    Parameters

    • hostAndPort: string

      the name and optionally port of the host to connect to

    • defaultPort: number

      the default port to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns SocketConnection

  • This is the asynchronous version of g_socket_client_connect_to_host().

    When the operation is finished callback will be called. You can then call g_socket_client_connect_to_host_finish() to get the result of the operation.

    Parameters

    • hostAndPort: string

      the name and optionally the port of the host to connect to

    • defaultPort: number

      the default port to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    • callback: AsyncReadyCallback

      a #GAsyncReadyCallback

    Returns void

  • Attempts to create a TCP connection to a service.

    This call looks up the SRV record for service at domain for the "tcp" protocol. It then attempts to connect, in turn, to each of the hosts providing the service until either a connection succeeds or there are no hosts remaining.

    Upon a successful connection, a new #GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

    In the event of any failure (DNS error, service not found, no hosts connectable) %NULL is returned and error (if non-%NULL) is set accordingly.

    Parameters

    • domain: string

      a domain name

    • service: string

      the name of the service to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns SocketConnection

  • This is the asynchronous version of g_socket_client_connect_to_service().

    Parameters

    • domain: string

      a domain name

    • service: string

      the name of the service to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    • callback: AsyncReadyCallback

      a #GAsyncReadyCallback

    Returns void

  • This is a helper function for g_socket_client_connect().

    Attempts to create a TCP connection with a network URI.

    uri may be any valid URI containing an "authority" (hostname/port) component. If a port is not specified in the URI, default_port will be used. TLS will be negotiated if #GSocketClient:tls is %TRUE. (#GSocketClient does not know to automatically assume TLS for certain URI schemes.)

    Using this rather than g_socket_client_connect() or g_socket_client_connect_to_host() allows #GSocketClient to determine when to use application-specific proxy protocols.

    Upon a successful connection, a new #GSocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

    In the event of any failure (DNS error, service not found, no hosts connectable) %NULL is returned and error (if non-%NULL) is set accordingly.

    Parameters

    • uri: string

      A network URI

    • defaultPort: number

      the default port to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns SocketConnection

  • This is the asynchronous version of g_socket_client_connect_to_uri().

    When the operation is finished callback will be called. You can then call g_socket_client_connect_to_uri_finish() to get the result of the operation.

    Parameters

    • uri: string

      a network uri

    • defaultPort: number

      the default port to connect to

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    • callback: AsyncReadyCallback

      a #GAsyncReadyCallback

    Returns void

  • emit(sigName: "event", connectable: SocketConnectable, connection: IOStream, ...args: any[]): void
  • emit(sigName: "notify::enable-proxy", ...args: any[]): void
  • emit(sigName: "notify::family", ...args: any[]): void
  • emit(sigName: "notify::local-address", ...args: any[]): void
  • emit(sigName: "notify::protocol", ...args: any[]): void
  • emit(sigName: "notify::proxy-resolver", ...args: any[]): void
  • emit(sigName: "notify::timeout", ...args: any[]): void
  • emit(sigName: "notify::tls", ...args: any[]): void
  • emit(sigName: "notify::tls-validation-flags", ...args: any[]): void
  • emit(sigName: "notify::type", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • forceFloating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freezeNotify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • getEnableProxy(): boolean
  • Gets the proxy enable state; see g_socket_client_set_enable_proxy()

    Returns boolean

  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • Gets the #GProxyResolver being used by client. Normally, this will be the resolver returned by g_proxy_resolver_get_default(), but you can override it with g_socket_client_set_proxy_resolver().

    Returns Gio.ProxyResolver

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • Gets the socket type of the socket client.

    See g_socket_client_set_socket_type() for details.

    Returns SocketType

  • getTimeout(): number
  • Gets the I/O timeout time for sockets created by client.

    See g_socket_client_set_timeout() for details.

    Returns number

  • getTls(): boolean
  • Gets whether client creates TLS connections. See g_socket_client_set_tls() for details.

    Returns boolean

  • Gets the TLS validation flags used creating TLS connections via client.

    This function does not work as originally designed and is impossible to use correctly. See #GSocketClient:tls-validation-flags for more information.

    Returns TlsCertificateFlags

  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • isFloating(): boolean
  • notify(propertyName: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns EventEmitter

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • setData(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • setEnableProxy(enable: boolean): void
  • Sets whether or not client attempts to make connections via a proxy server. When enabled (the default), #GSocketClient will use a #GProxyResolver to determine if a proxy protocol such as SOCKS is needed, and automatically do the necessary proxy negotiation.

    See also g_socket_client_set_proxy_resolver().

    Parameters

    • enable: boolean

      whether to enable proxies

    Returns void

  • Sets the socket family of the socket client. If this is set to something other than %G_SOCKET_FAMILY_INVALID then the sockets created by this object will be of the specified family.

    This might be useful for instance if you want to force the local connection to be an ipv4 socket, even though the address might be an ipv6 mapped to ipv4 address.

    Parameters

    Returns void

  • Sets the local address of the socket client. The sockets created by this object will bound to the specified address (if not %NULL) before connecting.

    This is useful if you want to ensure that the local side of the connection is on a specific port, or on a specific interface.

    Parameters

    Returns void

  • setProperty(propertyName: string, value?: any): void
  • Sets a property on an object.

    Parameters

    • propertyName: string

      the name of the property to set

    • Optional value: any

      the value

    Returns void

  • Sets the protocol of the socket client. The sockets created by this object will use of the specified protocol.

    If protocol is %G_SOCKET_PROTOCOL_DEFAULT that means to use the default protocol for the socket family and type.

    Parameters

    Returns void

  • Overrides the #GProxyResolver used by client. You can call this if you want to use specific proxies, rather than using the system default proxy settings.

    Note that whether or not the proxy resolver is actually used depends on the setting of #GSocketClient:enable-proxy, which is not changed by this function (but which is %TRUE by default)

    Parameters

    Returns void

  • Sets the socket type of the socket client. The sockets created by this object will be of the specified type.

    It doesn't make sense to specify a type of %G_SOCKET_TYPE_DATAGRAM, as GSocketClient is used for connection oriented services.

    Parameters

    Returns void

  • setTimeout(timeout: number): void
  • Sets the I/O timeout for sockets created by client. timeout is a time in seconds, or 0 for no timeout (the default).

    The timeout value affects the initial connection attempt as well, so setting this may cause calls to g_socket_client_connect(), etc, to fail with %G_IO_ERROR_TIMED_OUT.

    Parameters

    • timeout: number

      the timeout

    Returns void

  • setTls(tls: boolean): void
  • Sets whether client creates TLS (aka SSL) connections. If tls is %TRUE, client will wrap its connections in a #GTlsClientConnection and perform a TLS handshake when connecting.

    Note that since #GSocketClient must return a #GSocketConnection, but #GTlsClientConnection is not a #GSocketConnection, this actually wraps the resulting #GTlsClientConnection in a #GTcpWrapperConnection when returning it. You can use g_tcp_wrapper_connection_get_base_io_stream() on the return value to extract the #GTlsClientConnection.

    If you need to modify the behavior of the TLS handshake (eg, by setting a client-side certificate to use, or connecting to the #GTlsConnection::accept-certificate signal), you can connect to client's #GSocketClient::event signal and wait for it to be emitted with %G_SOCKET_CLIENT_TLS_HANDSHAKING, which will give you a chance to see the #GTlsClientConnection before the handshake starts.

    Parameters

    • tls: boolean

      whether to use TLS

    Returns void

  • Sets the TLS validation flags used when creating TLS connections via client. The default value is %G_TLS_CERTIFICATE_VALIDATE_ALL.

    This function does not work as originally designed and is impossible to use correctly. See #GSocketClient:tls-validation-flags for more information.

    Parameters

    Returns void

  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • thawNotify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compatControl(what: number, data: object): number
  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
