如何使用摘要与libcurl的身份验证POST HTTP请求 [英] How to post http request using digest authentication with libcurl

问题描述

我试图执行一个POST请求，我试图与摘要式身份验证做到这一点。与的libcurl ，我设置的选项：

I'm trying to perform a post request and I'm trying to do it with the digest authentication. with libcurl, I set the options:

url_easy_setopt(curl_handle, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);

curl_easy_setopt(curl_handle, CURLOPT_USERPWD, "user:pdw");

设置所有其他选项（邮局，URL和一切）之前。服务器关闭我的连接，我认为没有消化而成。我只是不知道如何自动获得摘要的质询 - 响应行为。如果我设置 HTTPAUTH 到 CURLAUTH_BASIC 它的连接codeS 的东西，我看带有verbose选项包含 =授权基本报头。随着消化没有标题。

before setting all the other option (post, url and everything). The server closes my connection and I think that no digest is made. I just don't know how automatically obtain the challenge-response behavior of the digest. If I set HTTPAUTH to CURLAUTH_BASIC it encodes the stuff, I see with the VERBOSE option the header containing authorization = basic. With digest no headers.

你知道我怎么能做到这一点，或者你可以给我一些例子吗？我真的搜索无处不在。

Do you know how can I do it, or can you give me some example? I really search everywhere.

推荐答案

有关基本 POST 要求你应该做的：

For a basic POST request you should do:

curl_easy_setopt(hnd, CURLOPT_USERPWD, "user:pwd");
curl_easy_setopt(hnd, CURLOPT_HTTPAUTH, (long)CURLAUTH_DIGEST);
curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "POST");

有关一个多 POST （a.k.a 的multipart / form-data的）

For a multipart POST (a.k.a multipart/form-data):

struct curl_httppost *post;
struct curl_httppost *postend;
/* setup your POST body with `curl_formadd(&post, &postend, ...)` */
curl_easy_setopt(hnd, CURLOPT_USERPWD, "user:pwd");
curl_easy_setopt(hnd, CURLOPT_HTTPPOST, post);
curl_easy_setopt(hnd, CURLOPT_HTTPAUTH, (long)CURLAUTH_DIGEST);
curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "POST");

临提示：使用卷曲与命令行工具 - libcurl的request.c ：它输出到这个C文件中用来执行相应的请求的选项列表。

Pro-tip: use curl command-line tool with --libcurl request.c: it outputs into this C file the list of options used to perform the corresponding request.
