NAME

CURLOPT_DISALLOW_USERNAME_IN_URL - disallow specifying username in the URL

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DISALLOW_USERNAME_IN_URL,
                          long disallow);

DESCRIPTION

A long parameter set to 1 tells the library to not allow URLs that include a username.

This is the equivalent to the CURLU_DISALLOW_USER flag for the curl_url_set(3) function.

{
  CURL *curl = curl_easy_init();
  if(curl) {

    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    curl_easy_setopt(curl, CURLOPT_DISALLOW_USERNAME_IN_URL, 1L);

    curl_easy_perform(curl);
  }
}

AVAILABILITY

Added in 7.61.0

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.

curl_easy_perform(3) returns CURLE_LOGIN_DENIED if this option is enabled and a URL containing a username is specified.
