当我尝试使用代码从 HTTPS 获取数据时
When I trying to get data from HTTPS with code
static size_t WriteCallback(void *contents, size_t size, size_t nmemb, void *userp)
{
((std::string*)userp)->append((char*)contents, size * nmemb);
return size * nmemb;
}
string* NetIO::getUrlContent(string URL) {
CURL *curl;
CURLcode res;
string *s = new string("");
curl = curl_easy_init();
if (curl) {
//curl_easy_setopt(curl, CURLOPT_URL, URL);
curl_easy_setopt(curl, CURLOPT_URL, "https://ya.ru/");
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, s);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
return s;
}
它无法接收 HTTPS 响应的内容并将其写入 s
变量 - s
包含".但是,如果我将 URL 更改为 HTTP - 此代码运行良好,并且 s
包含页面的 HTML 代码.
It can't receive content of HTTPS response and write it to the s
variable - s
contains "". But if I change URL to HTTP - this code works very well and s
contains HTML code of the page.
curl_easy_setopt(curl, CURLOPT_URL, "http://tatarstan.shop.megafon.ru/");
如何解决这个问题?
谢谢!
更新:如果我添加
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
我的代码运行良好.为什么没有 CURLOPT_SSL_VERIFYPEER=0 就不能工作?
Than my code works well. Why it can't work without CURLOPT_SSL_VERIFYPEER=0?
我有一些 Visual Studio 解决方案.它包含 2 个项目 - libcurl,使用设置编译:
I have some Visual Studio solution. It contains 2 project - libcurl, that compiled with settings:
和第二个项目,这取决于 libcurl 项目:
and second project, that depends on libcurl project:
已解决!感谢@hank!
Solved! Thanks to @hank!
我的解决方案是:
1) 在 Google Chrome 中打开您的网站,打开证书信息.
1) Open your site in Google Chrome, open certificate info.
2) 将其及其每个父证书导出为 X.509.将证书文件合并为一个证书文件 - 制作证书链.
2) Export it and each of his parent certs as X.509. Concat cert files into the one cert file - make cert chain.
3) 使用带有代码的证书链的文件
3) Use file with cert chain with the code
curl_easy_setopt(curl, CURLOPT_CAINFO, "c:\Art\Projects\LifeSimLauncher\MyStaticLib\lifesim.biz.crt.cer");
