CURLOPT_PROXYUSERPWD(3) Library Functions Manual CURLOPT_PROXYUSERPWD(3)

CURLOPT_PROXYUSERPWD - username and password to use for proxy authentication

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYUSERPWD, char *userpwd);

Pass a char pointer as parameter, which should be [username]:[password] to use for the connection to the HTTP proxy. Both the name and the password are URL decoded before used, so to include for example a colon in the username you should encode it as %3A. (This is different to how CURLOPT_USERPWD(3) is used - beware.)

Use CURLOPT_PROXYAUTH(3) to specify the authentication method.

The application does not have to keep the string around after setting this option.

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

NULL

This functionality affects all supported protocols

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
    curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
    curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "clark%20kent:superman");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

Added in curl 7.1

Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
