CURLOPT_SOCKS5_AUTH − methods for SOCKS5 proxy authentication
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS5_AUTH, long bitmask);
Pass a long as parameter, which is set to a bitmask, to tell libcurl which authentication method(s) are allowed for SOCKS5 proxy authentication. The only supported flags are CURLAUTH_BASIC, which allows username/password authentication, CURLAUTH_GSSAPI, which allows GSS−API authentication, and CURLAUTH_NONE, which allows no authentication. Set the actual username and password with the CURLOPT_PROXYUSERPWD(3) option.
CURLAUTH_BASIC | CURLAUTH_GSSAPI
This functionality affects all supported protocols
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL,
"https://example.com");
/* request to
use a SOCKS5 proxy */
curl_easy_setopt(curl, CURLOPT_PROXY,
"socks5://user:[email protected]");
/* enable
username/password authentication only */
curl_easy_setopt(curl, CURLOPT_SOCKS5_AUTH,
CURLAUTH_BASIC);
/* Perform the
request */
curl_easy_perform(curl);
}
}
CURLAUTH_* macros became long types in 7.26.0, prior to this version a long cast was necessary when passed to curl_easy_setopt(3).
Added in curl 7.55.0
curl_easy_setopt(3) returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non−zero means an error occurred, see libcurl−errors(3).
CURLOPT_PROXY(3), CURLOPT_PROXYTYPE(3)
