.TH CURLOPT_SOCKS_PROXY 3 "16 Nov 2016" "libcurl 7.52.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_SOCKS_PROXY \- set socks proxy to use
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS_PROXY, char *proxy);
|
|
.SH DESCRIPTION
|
|
TODO: Make this text specific to HTTPS proxy. (Added in 7.XXX)
|
|
Set the \fIproxy\fP to use for the upcoming request. The parameter should be a
|
|
char * to a zero terminated string holding the host name or dotted numerical
|
|
IP address. A numerical IPv6 address must be written within [brackets].
|
|
|
|
To specify port number in this string, append :[port] to the end of the host
|
|
name. The proxy's port number may optionally be specified with the separate
|
|
option \fICURLOPT_PROXYPORT(3)\fP. If not specified, libcurl will default to
|
|
using port 1080 for proxies.
|
|
|
|
The proxy string may be prefixed with [scheme]:// to specify which kind of
|
|
proxy is used. Use socks4://, socks4a://, socks5:// or socks5h:// (the last
|
|
one to enable socks5 and asking the proxy to do the resolving, also known as
|
|
\fICURLPROXY_SOCKS5_HOSTNAME\fP type) to request the specific SOCKS version to
|
|
be used. No scheme specified or http://, will be treated as HTTP proxies.
|
|
|
|
Without a scheme prefix, \fICURLOPT_PROXYTYPE(3)\fP can be used to specify
|
|
which kind of proxy the string identifies.
|
|
|
|
When you tell the library to use a HTTP proxy, libcurl will transparently
|
|
convert operations to HTTP even if you specify an FTP URL etc. This may have
|
|
an impact on what other features of the library you can use, such as
|
|
\fICURLOPT_QUOTE(3)\fP and similar FTP specifics that don't work unless you
|
|
tunnel through the HTTP proxy. Such tunneling is activated with
|
|
\fICURLOPT_HTTPPROXYTUNNEL(3)\fP.
|
|
|
|
libcurl respects the environment variables \fBhttp_proxy\fP, \fBftp_proxy\fP,
|
|
\fBall_proxy\fP etc, if any of those are set. The \fICURLOPT_PROXY(3)\fP
|
|
option does however override any possibly set environment variables.
|
|
|
|
Setting the proxy string to "" (an empty string) will explicitly disable the
|
|
use of a proxy, even if there is an environment variable set for it.
|
|
|
|
A proxy host string can also include protocol scheme (http://) and embedded
|
|
user + password.
|
|
.SH DEFAULT
|
|
Default is NULL, meaning no proxy is used.
|
|
|
|
When you set a host name to use, do not assume that there's any particular
|
|
single port number used widely for proxies. Specify it!
|
|
.SH PROTOCOLS
|
|
All except file://. Note that some protocols don't do very well over proxy.
|
|
.SH EXAMPLE
|
|
TODO
|
|
.SH AVAILABILITY
|
|
Since 7.14.1 the proxy environment variable names can include the protocol
|
|
scheme.
|
|
|
|
Since 7.21.7 the proxy string supports the socks protocols as "schemes".
|
|
|
|
Since 7.50.2, unsupported schemes in proxy strings cause libcurl to return
|
|
error.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
