Implemented Interfaces

GSimpleProxyResolver implements GProxyResolver.

Includes

#include <gio/gio.h>

Description

GSimpleProxyResolver is a simple GProxyResolver implementation that handles a single default proxy, multiple URI-scheme-specific proxies, and a list of hosts that proxies should not be used for.

GSimpleProxyResolver is never the default proxy resolver, but it can be used as the base class for another proxy resolver implementation, or it can be created and used manually, such as with g_socket_client_set_proxy_resolver().

Functions

g_simple_proxy_resolver_new ()

GProxyResolver *
g_simple_proxy_resolver_new (const gchar *default_proxy,
                             gchar **ignore_hosts);

Creates a new GSimpleProxyResolver. See “default-proxy” and “ignore-hosts” for more details on how the arguments are interpreted.

Parameters

default_proxy	the default proxy to use, eg "socks://192.168.1.1".	[allow-none]
ignore_hosts	an optional list of hosts/IP addresses to not use a proxy for.	[allow-none]

Returns

(transfer full) a new GSimpleProxyResolver

Since 2.36

g_simple_proxy_resolver_set_default_proxy ()

void
g_simple_proxy_resolver_set_default_proxy
                               (GSimpleProxyResolver *resolver,
                                const gchar *default_proxy);

Sets the default proxy on resolver , to be used for any URIs that don't match “ignore-hosts” or a proxy set via g_simple_proxy_resolver_set_uri_proxy().

If default_proxy starts with "socks://", GSimpleProxyResolver will treat it as referring to all three of the socks5, socks4a, and socks4 proxy types.

Parameters

resolver	a GSimpleProxyResolver
default_proxy	the default proxy to use

Since 2.36

g_simple_proxy_resolver_set_ignore_hosts ()

void
g_simple_proxy_resolver_set_ignore_hosts
                               (GSimpleProxyResolver *resolver,
                                gchar **ignore_hosts);

Sets the list of ignored hosts.

See “ignore-hosts” for more details on how the ignore_hosts argument is interpreted.

Parameters

resolver	a GSimpleProxyResolver
ignore_hosts	`NULL`-terminated list of hosts/IP addresses to not use a proxy for

Since 2.36

g_simple_proxy_resolver_set_uri_proxy ()

void
g_simple_proxy_resolver_set_uri_proxy (GSimpleProxyResolver *resolver,
                                       const gchar *uri_scheme,
                                       const gchar *proxy);

Adds a URI-scheme-specific proxy to resolver ; URIs whose scheme matches uri_scheme (and which don't match “ignore-hosts”) will be proxied via proxy .

As with “default-proxy”, if proxy starts with "socks://", GSimpleProxyResolver will treat it as referring to all three of the socks5, socks4a, and socks4 proxy types.

Parameters

resolver	a GSimpleProxyResolver
uri_scheme	the URI scheme to add a proxy for
proxy	the proxy to use for `uri_scheme`

Since 2.36

Types and Values

struct GSimpleProxyResolver

struct GSimpleProxyResolver;

A GProxyResolver implementation for using a fixed set of proxies.

Property Details

The `“default-proxy”` property

  “default-proxy”            gchar *

The default proxy URI that will be used for any URI that doesn't match “ignore-hosts”, and doesn't match any of the schemes set with g_simple_proxy_resolver_set_uri_proxy().

Note that as a special case, if this URI starts with "socks://", GSimpleProxyResolver will treat it as referring to all three of the socks5, socks4a, and socks4 proxy types.

Flags: Read / Write

Default value: NULL

The `“ignore-hosts”` property

  “ignore-hosts”             GStrv

A list of hostnames and IP addresses that the resolver should allow direct connections to.

Entries can be in one of 4 formats:

A hostname, such as "example.com", ".example.com", or "*.example.com", any of which match "example.com" or any subdomain of it.
An IPv4 or IPv6 address, such as "192.168.1.1", which matches only that address.
A hostname or IP address followed by a port, such as "example.com:80", which matches whatever the hostname or IP address would match, but only for URLs with the (explicitly) indicated port. In the case of an IPv6 address, the address part must appear in brackets: "[::1]:443"
An IP address range, given by a base address and prefix length, such as "fe80::/10", which matches any address in that range.

Note that when dealing with Unicode hostnames, the matching is done against the ASCII form of the name.

Also note that hostname exclusions apply only to connections made to hosts identified by name, and IP address exclusions apply only to connections made to hosts identified by address. That is, if example.com has an address of 192.168.1.1, and the :ignore-hosts list contains only "192.168.1.1", then a connection to "example.com" (eg, via a GNetworkAddress) will use the proxy, and a connection to "192.168.1.1" (eg, via a GInetSocketAddress) will not.

These rules match the "ignore-hosts"/"noproxy" rules most commonly used by other applications.
