如何使用libcurl的REST API做基于cookie的认证？

问题描述 投票：1回答：2

我的Web服务器支持基于Cookie的身份验证。但我无法理解如何使用libcurl的REST API来实现它。我去通的例子https://curl.haxx.se/libcurl/c/cookie_interface.html为好。但我搞不清如何利用这个例子进行身份验证。每当我收到“HTTP / 1.1 401未经授权”的错误

代码：

        curl_easy_setopt(curl, CURLOPT_URL, 
        "https://samplepage.com/LicenseReportingApplication/authenticate");
        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
        curl_easy_setopt(curl, CURLOPT_COOKIEFILE, ""); /* start cookie engine */
        curl_easy_setopt(curl, CURLOPT_POST, 1L);
        curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
        curl_easy_setopt(curl, CURLOPT_UNRESTRICTED_AUTH, 1L);
        curl_easy_setopt(curl, CURLOPT_HTTPAUTH, (long)CURLAUTH_ANY);
        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_easy_setopt(curl, CURLOPT_PROTOCOLS, CURLPROTO_ALL);
        curl_easy_setopt(curl, CURLOPT_USERPWD, "root:admin123");
        res = curl_easy_perform(curl);

下面是错误日志

该401 Unauthorized响应意味着你Authorization:头被认为不正确或不通过服务器就够了。未能发出正确的cookie不会引起401。
