Description

A Proxy handles connecting to a remote host via a given type of proxy server. It is implemented by the 'gio-proxy' extension point. The extensions are named after their proxy protocol name. As an example, a SOCKS5 proxy implementation can be retrieved with the name 'socks5' using the function iOExtensionPointGetExtensionByName.

Cast to Proxy, for types for which this is known to be safe. For general casts, use castTo.

Methods

Overloaded methods

connect

proxyConnect Source #

Arguments

:: (HasCallStack, MonadIO m, IsProxy a, IsIOStream b, IsProxyAddress c, IsCancellable d)
=> a	`proxy`: a `Proxy`
-> b	`connection`: a `IOStream`
-> c	`proxyAddress`: a `ProxyAddress`
-> Maybe d	`cancellable`: a `Cancellable`
-> m IOStream	Returns: a `IOStream` that will replace `connection`. This might be the same as `connection`, in which case a reference will be added. (Can throw `GError`)

Given connection to communicate with a proxy (eg, a SocketConnection that is connected to the proxy server), this does the necessary handshake to connect to proxyAddress, and if required, wraps the IOStream to handle proxy payload.

connectAsync

proxyConnectAsync Source #

Arguments

:: (HasCallStack, MonadIO m, IsProxy a, IsIOStream b, IsProxyAddress c, IsCancellable d)
=> a	`proxy`: a `Proxy`
-> b	`connection`: a `IOStream`
-> c	`proxyAddress`: a `ProxyAddress`
-> Maybe d	`cancellable`: a `Cancellable`
-> Maybe AsyncReadyCallback	`callback`: a `AsyncReadyCallback`
-> m ()

Asynchronous version of proxyConnect.

Since: 2.26

connectFinish

proxyConnectFinish Source #

Arguments

:: (HasCallStack, MonadIO m, IsProxy a, IsAsyncResult b)
=> a	`proxy`: a `Proxy`
-> b	`result`: a `AsyncResult`
-> m IOStream	Returns: a `IOStream`. (Can throw `GError`)

See proxyConnect.

Since: 2.26

getDefaultForProtocol

proxyGetDefaultForProtocol Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`protocol`: the proxy protocol name (e.g. http, socks, etc)
-> m Proxy	Returns: return a `Proxy` or NULL if protocol is not supported.

Find the gio-proxy extension point for a proxy implementation that supports the specified protocol.

Since: 2.26

supportsHostname

proxySupportsHostname Source #

Arguments

:: (HasCallStack, MonadIO m, IsProxy a)
=> a	`proxy`: a `Proxy`
-> m Bool	Returns: `True` if hostname resolution is supported.

Some proxy protocols expect to be passed a hostname, which they will resolve to an IP address themselves. Others, like SOCKS4, do not allow this. This function will return False if proxy is implementing such a protocol. When False is returned, the caller should resolve the destination hostname first, and then pass a ProxyAddress containing the stringified IP address to proxyConnect or proxyConnectAsync.
