I am writing a program that must communicate over https to a server to
send and retrieve some data.
I use OpenSSL (openssl-1.0.0a
<http://www.openssl.org/source/openssl-1.0.0a.tar.gz> from the first of
juli) and Libcurl (curl-7.21.0
<http://curl.haxx.se/download/curl-7.21.0.zip> )
In the constructor of my class, I do:
{
// curl_global_init() should only be issued once
if (!smIsGlobalInitialized)
{
print("curl_global_init")
// curl_global_init may only be called once for each programm
CURLcode res = curl_global_init(CURL_GLOBAL_ALL);
if (res != CURLE_OK)
{
error("Failed to init libCurl, errorcode=%1%", res));
}
smIsGlobalInitialized = true;
}
curl_version_info_data * vinfo = curl_version_info( CURLVERSION_NOW
);
if( vinfo->features & CURL_VERSION_SSL )
{
print("libcurl does support SSL");
}
else
{
error("No SSL support from libcurl");
}
}
And in my getData() function, I do:
// the url must start with "https://";
bool CurlClient::getData(std::string filepath, std::string url)
{
print("getDataFile: Url %1% ,body to %2% ", url, filepath);
mErrorDetected = false;
mCurlErrorCode = CURLE_OK;
CURL *curlHandle = curl_easy_init();
assert(curlHandle != 0, EXT_RESTART, SDSCAT_SWERROR, ("Error
initializing Curl library."));
// reset the curl option to the defaults
curl_easy_reset(curlHandle);
UcsFile dataFile = {filepath, NULL};
curl_easy_setopt(curlHandle, CURLOPT_URL, url.c_str());
curl_easy_setopt(curlHandle, CURLOPT_WRITEFUNCTION,
CurlClient::writeFile);
curl_easy_setopt(curlHandle, CURLOPT_WRITEDATA, &dataFile);
curl_easy_perform(curlHandle);
if (dataFile.stream)
{
fclose(dataFile.stream);
}
curl_easy_cleanup(curlHandle);
return mErrorDetected;
}
When I execute my getData function, I retrieve error code 60
(LibCurl error code: 60, Peer certificate cannot be authenticated with
known CA certificates)
But when I add:
curl_easy_setopt(curlHandle, CURLOPT_SSL_VERIFYPEER, 0L);
It all works fine.
What am I doing wrong?
