GI.Gio.Objects.SocketClient

Description

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

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

The type of the SocketConnection 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 TcpConnection.

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

Since: 2.22

Methods

Overloaded methods

addApplicationProxy

socketClientAddApplicationProxy Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient

-> Text

protocol: The proxy protocol

-> m () 

Enable proxy protocols to be handled by the application. When the indicated proxy protocol is returned by the ProxyResolver, SocketClient will consider this protocol as supported but will not try to find a Proxy instance to handle handshaking. The application must check for this case by calling socketConnectionGetRemoteAddress on the returned SocketConnection, and seeing if it's a ProxyAddress 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.

connect

socketClientConnect Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsSocketConnectable b, IsCancellable c) 
=> a

client: a SocketClient.

-> b

connectable: a SocketConnectable specifying the remote address.

-> Maybe c

cancellable: optional Cancellable object, Nothing to ignore.

-> m SocketConnection

Returns: a SocketConnection on success, Nothing on error. (Can throw GError)

Tries to resolve the connectable and make a network connection to it.

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

The type of the SocketConnection object returned depends on the type of the underlying socket that is used. For instance, for a TCP/IP connection it will be a TcpConnection.

The socket created will be the same family as the address that the connectable resolves to, unless family is set with socketClientSetFamily or indirectly via socketClientSetLocalAddress. The socket type defaults to SocketTypeStream but can be set with socketClientSetSocketType.

If a local address is specified with socketClientSetLocalAddress the socket will be bound to this address before connecting.

connectAsync

socketClientConnectAsync Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsSocketConnectable b, IsCancellable c) 
=> a

client: a SocketClient

-> b

connectable: a SocketConnectable specifying the remote address.

-> Maybe c

cancellable: a Cancellable, or Nothing

-> Maybe AsyncReadyCallback

callback: a AsyncReadyCallback

-> m () 

This is the asynchronous version of socketClientConnect.

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

Since: 2.22

connectFinish

socketClientConnectFinish Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsAsyncResult b) 
=> a

client: a SocketClient.

-> b

result: a AsyncResult.

-> m SocketConnection

Returns: a SocketConnection on success, Nothing on error. (Can throw GError)

Finishes an async connect operation. See socketClientConnectAsync

Since: 2.22

connectToHost

socketClientConnectToHost Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsCancellable b) 
=> a

client: a SocketClient

-> Text

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

-> Word16

defaultPort: the default port to connect to

-> Maybe b

cancellable: a Cancellable, or Nothing

-> m SocketConnection

Returns: a SocketConnection on success, Nothing on error. (Can throw GError)

This is a helper function for socketClientConnect.

Attempts to create a TCP connection to the named host.

hostAndPort 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 hostAndPort then defaultPort will be used as the port number to connect to.

In general, hostAndPort is expected to be provided by the user (allowing them to give the hostname, and a port override if necessary) and defaultPort 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 SocketConnection 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) Nothing is returned and error (if non-Nothing) is set accordingly.

-> Maybe b

cancellable: a Cancellable, or Nothing

-> m SocketConnection

Returns: a SocketConnection if successful, or Nothing on error (Can throw GError)

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 SocketConnection 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) Nothing is returned and error (if non-Nothing) is set accordingly.

connectToUri

socketClientConnectToUri Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsCancellable b) 
=> a

client: a SocketClient

-> Text

uri: A network URI

-> Word16

defaultPort: the default port to connect to

-> Maybe b

cancellable: a Cancellable, or Nothing

-> m SocketConnection

Returns: a SocketConnection on success, Nothing on error. (Can throw GError)

This is a helper function for socketClientConnect.

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, defaultPort will be used. TLS will be negotiated if SocketClient:tls is True. (tSocketClient does not know to automatically assume TLS for certain URI schemes.)

Using this rather than socketClientConnect or socketClientConnectToHost allows SocketClient to determine when to use application-specific proxy protocols.

Upon a successful connection, a new SocketConnection 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) Nothing is returned and error (if non-Nothing) is set accordingly.

Since: 2.22

setEnableProxy

socketClientSetEnableProxy Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> Bool

enable: whether to enable proxies

-> m () 

Sets whether or not client attempts to make connections via a proxy server. When enabled (the default), SocketClient will use a ProxyResolver to determine if a proxy protocol such as SOCKS is needed, and automatically do the necessary proxy negotiation.

See also socketClientSetProxyResolver.

Since: 2.26

setFamily

socketClientSetFamily Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> SocketFamily

family: a SocketFamily

-> m () 

Sets the socket family of the socket client. If this is set to something other than SocketFamilyInvalid 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.

Since: 2.22

setLocalAddress

socketClientSetLocalAddress Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsSocketAddress b) 
=> a

client: a SocketClient.

-> Maybe b

address: a SocketAddress, or Nothing

-> m () 

Sets the local address of the socket client. The sockets created by this object will bound to the specified address (if not Nothing) 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.

Since: 2.22

setProtocol

socketClientSetProtocol Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> SocketProtocol

protocol: a SocketProtocol

-> m () 

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

If protocol is 0 that means to use the default protocol for the socket family and type.

Since: 2.22

setProxyResolver

socketClientSetProxyResolver Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a, IsProxyResolver b) 
=> a

client: a SocketClient.

-> Maybe b

proxyResolver: a ProxyResolver, or Nothing for the default.

-> m () 

Overrides the ProxyResolver 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 SocketClient:enable-proxy, which is not changed by this function (but which is True by default)

Since: 2.36

setSocketType

socketClientSetSocketType Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> SocketType

type: a SocketType

-> m () 

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 SocketTypeDatagram, as GSocketClient is used for connection oriented services.

Since: 2.22

setTimeout

socketClientSetTimeout Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> Word32

timeout: the timeout

-> m () 

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 socketClientConnect, etc, to fail with IOErrorEnumTimedOut.

Since: 2.26

setTls

socketClientSetTls Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> Bool

tls: whether to use TLS

-> m () 

Sets whether client creates TLS (aka SSL) connections. If tls is True, client will wrap its connections in a TlsClientConnection and perform a TLS handshake when connecting.

Note that since SocketClient must return a SocketConnection, but TlsClientConnection is not a SocketConnection, this actually wraps the resulting TlsClientConnection in a TcpWrapperConnection when returning it. You can use tcpWrapperConnectionGetBaseIoStream on the return value to extract the TlsClientConnection.

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

Since: 2.28

setTlsValidationFlags

socketClientSetTlsValidationFlags Source #

Arguments

:: (HasCallStack, MonadIO m, IsSocketClient a) 
=> a

client: a SocketClient.

-> [TlsCertificateFlags]

flags: the validation flags

-> m () 

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

event

type C_SocketClientEventCallback = Ptr () -> CUInt -> Ptr SocketConnectable -> Ptr IOStream -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type SocketClientEventCallback Source #

Arguments

 = SocketClientEvent

event: the event that is occurring

-> SocketConnectable

connectable: the SocketConnectable that event is occurring on

-> Maybe IOStream

connection: the current representation of the connection

-> IO () 

Emitted when client's activity on connectable changes state. Among other things, this can be used to provide progress information about a network connection in the UI. The meanings of the different event values are as follows:

Each event except SocketClientEventComplete may be emitted multiple times (or not at all) for a given connectable (in particular, if client ends up attempting to connect to more than one address). However, if client emits the event signal at all for a given connectable, that it will always emit it with SocketClientEventComplete when it is done.

Note that there may be additional SocketClientEvent values in the future; unrecognized event values should be ignored.
