使用libcurl& SSL [英] Using libcurl & SSL

问题描述

我发现有关这个主题的信息真的很少。我已经有一个dll使用libcurl成功的帖子。

I've found there is really very little information around on this topic. I already have a dll making successful posts using libcurl.

我编译libcurl与openssl的ssl功能。

I've compiled libcurl with openssl for ssl functionality.

    curl_easy_setopt(handle, CURLOPT_ERRORBUFFER, errorBuffer);

    //curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER , 1);
    //curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST , 1);
    //curl_easy_setopt(curl, CURLOPT_CAINFO , "./ca.cert");

    curl_easy_setopt(handle, CURLOPT_POSTFIELDS, cParam); 
    curl_easy_setopt(handle, CURLOPT_POSTFIELDSIZE, strlen(cParam));
    curl_easy_setopt(handle, CURLOPT_FOLLOWLOCATION, 1);
    curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, Request::writer);   
    curl_easy_setopt(handle, CURLOPT_WRITEDATA, &buffer); 
    curl_easy_setopt(handle, CURLOPT_URL, cURL);

我对以前做过的人的问题，以使SSL工作（只要证书存在）？还是更复杂？

My question to those who've done this before, is it as easy as just adding those lines above to get SSL to work (as long as the certificate exists)? Or is it more complicated?

有趣的是，我不完全确定SSL是如何工作的。我从来没有使用过它。我需要在我的应用程序中存储密钥，并与每个请求一起发送吗？无论如何我的主要问题是第一。先谢谢。

The funny thing is I'm not completely sure how SSL works. I've never worked with it before. Do I need to store a key in my application and send it with each request? Anyway my main question was the first. Thank you in advance.

推荐答案

是的，很简单。只要确保您拥有的ca.cert文件是一个真正的CA证书，可以验证您的服务器的证书。

Yes, it is that simple. Just make sure that the "ca.cert" file you have is a true CA cert that can verify your server's certificate.
