我正在开发一个小应用程序。 为了测试purpouse,我尝试在ntlm代理后面使用libcurl“ping”google。 这是我的c ++代码:

CURLcode testConnection(void)
{
    CURL *curl;
    CURLcode res = CURLE_OK;
    res = curl_global_init(CURL_GLOBAL_ALL);
    curl = curl_easy_init();
    if (curl)
    {
        cout << "Url: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_URL, "http://www.google.com")) << "\n";
        cout << "T-out: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_CONNECTTIMEOUT, 3)) << "\n";
        cout << "No_body: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_NOBODY, true)) << "\n";
        cout << "Proxy Url: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_PROXY, "proxyrm.wind.root.it")) << "\n";
        cout << "Proxy Port: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_PROXYPORT, 8080)) << "\n";
        cout << "Ntml: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_HTTPAUTH, CURLAUTH_NTLM)) << "\n";
        cout << "Verbose: " << curl_easy_strerror(curl_easy_setopt(curl, CURLOPT_VERBOSE, true)) << "\n";

        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
    }
    else
        res = CURLE_FAILED_INIT;
    curl_global_cleanup();
    return res;
}

所有这些都很顺利,因为详细的输出如下。

Url: No error

No_body: No error
Proxy Url: No error

Ntml: No error

但是,如果我尝试ping https://google.com,结果就会变成这个

Curl Final: Failure when receiving data from the peer

在命令行中使用curl允许我ping https(我必须指定-k参数),但我不知道这是否真的相关。有人可以帮我弄清楚发生了什么吗?以及如何避免这种情况?

1 个答案:

答案 0 :(得分:0)

解决:我错过了这条指令

curl_easy_setopt(ctx, CURLOPT_PROXYUSERPWD, ":");

这(我认为)告诉curl使用用户名从SO中检索的密码通过througt ntlm auth
