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.

This is NULL by default.

All

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);
  }
}

Always

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