Checks if resolver can be used on this system. (This is used internally; gio.proxy_resolver.ProxyResolver.getDefault will only return a proxy resolver that returns true for this method.)
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.
Asynchronous lookup of proxy. See gio.proxy_resolver.ProxyResolver.lookup for more details.
Call this function to obtain the array of proxy URIs when gio.proxy_resolver.ProxyResolver.lookupAsync is complete. See gio.proxy_resolver.ProxyResolver.lookup for more details.
Gets the default #GProxyResolver for the system.
gio.proxy_resolver.ProxyResolver provides synchronous and asynchronous network proxy resolution. gio.proxy_resolver.ProxyResolver is used within gio.socket_client.SocketClient through the method gio.socket_connectable.SocketConnectable.proxyEnumerate.
Implementations of gio.proxy_resolver.ProxyResolver based on libproxy and GNOME settings can be found in glib-networking. GIO comes with an implementation for use inside Flatpak portals.
