Issue
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;
}
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/");
How to fix this issue?
Thank you! ❤
UPDATE: If I add
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
Than my code works well. Why it can't work without CURLOPT_SSL_VERIFYPEER=0?
I have some Visual Studio solution. It contains 2 project - libcurl, that compiled with settings:
and second project, that depends on libcurl project:
Solution
Solved! Thanks to @hank!
My solution is:
1) Open your site in Google Chrome, open certificate info.
2) Export it and each of his parent certs as X.509. Concat cert files into the one cert file - make cert chain.
3) Use file with cert chain with the code
curl_easy_setopt(curl, CURLOPT_CAINFO, "c:\\Art\\Projects\\LifeSimLauncher\\MyStaticLib\\lifesim.biz.crt.cer");
