Detailed Description

ProxyResolver - Asynchronous and cancellable network proxy resolver.

ProxyResolver provides synchronous and asynchronous network proxy resolution. ProxyResolver is used within ClientSocket through the method Gio::SocketConnectable::proxy_enumerate().

Since glibmm 2.28:

Constructor & Destructor Documentation

Gio::ProxyResolver::ProxyResolver ( )

You should derive from this class to use it.

Member Function Documentation

static void Gio::ProxyResolver::add_interface ( GType  gtype_implementer)
static
static Glib::RefPtr<ProxyResolver> Gio::ProxyResolver::get_default ( )
static

Gets the default ProxyResolver for the system.

Since glibmm 2.26:
Returns
The default ProxyResolver.
static GType Gio::ProxyResolver::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

GProxyResolver* Gio::ProxyResolver::gobj ( )
inline

Provides access to the underlying C GObject.

const GProxyResolver* Gio::ProxyResolver::gobj ( ) const
inline

Provides access to the underlying C GObject.

bool Gio::ProxyResolver::is_supported ( ) const

Checks if resolver can be used on this system.

(This is used internally; g_proxy_resolver_get_default() will only return a proxy resolver that returns true for this method.)

Since glibmm 2.26:
Returns
true if resolver is supported.
std::vector<Glib::ustring> Gio::ProxyResolver::lookup ( const Glib::ustring uri,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Looks into the system proxy configuration to determine what proxy, if any, to use to connect to uri.

The returned proxy URIs are of the form <protocol>://[user[:password]@]host:port or direct://, where <protocol> could be http, rtsp, socks or other proxying protocol.

If you don't know what network protocol is being used on the socket, you should use none as the URI protocol. In this case, the resolver might still return a generic proxy type (such as SOCKS), but would not return protocol-specific proxy types (such as http).

direct:// is used when no proxy is needed. Direct connection should not be attempted unless it is part of the returned array of proxies.

Since glibmm 2.26:
Parameters
uriA URI representing the destination to connect to.
cancellableA Cancellable, or nullptr.
Returns
A nullptr-terminated array of proxy URIs.
Exceptions
Glib::Error
std::vector<Glib::ustring> Gio::ProxyResolver::lookup ( const Glib::ustring uri)

Looks into the system proxy configuration to determine what proxy, if any, to use to connect to uri.

The returned proxy URIs are of the form <protocol>://[user[:password]@]host:port or direct://, where <protocol> could be http, rtsp, socks or other proxying protocol.

If you don't know what network protocol is being used on the socket, you should use none as the URI protocol. In this case, the resolver might still return a generic proxy type (such as SOCKS), but would not return protocol-specific proxy types (such as http).

direct:// is used when no proxy is needed. Direct connection should not be attempted unless it is part of the returned array of proxies.

Parameters
uria URI representing the destination to connect to.
void Gio::ProxyResolver::lookup_async ( const Glib::ustring uri,
const SlotAsyncReady &  slot,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Asynchronous lookup of proxy.

See lookup() for more details.

Parameters
uria URI representing the destination to connect to.
slotA callback slot to call after the resolution completes.
cancellableA Cancellable object which can be used to cancel the operation.
void Gio::ProxyResolver::lookup_async ( const Glib::ustring uri,
const SlotAsyncReady &  slot 
)

Asynchronous lookup of proxy.

See lookup() for more details.

Parameters
uria URI representing the destination to connect to.
slotA callback slot to call after the resolution completes.
std::vector<Glib::ustring> Gio::ProxyResolver::lookup_finish ( const Glib::RefPtr< AsyncResult >&  result)

Call this function to obtain the array of proxy URIs when g_proxy_resolver_lookup_async() is complete.

See g_proxy_resolver_lookup() for more details.

Since glibmm 2.26:
Parameters
resultThe result passed to your SlotAsyncReady.
Returns
A nullptr-terminated array of proxy URIs.
Exceptions
Glib::Error

noexcept
