sorry to bother, but I meet another problem now.
when I don't give CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA, the code
works fine, successfully locate to new url.
But when I give CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA, virtual studio
accurs to exception.
I just don't know why,thanks al ot.
here is the code:
..........................write funtion...............................
size_t writeCallBack(void *data, size_t size, size_t nmemb, void *stream)
{
return fwrite(data, size, nmemb, (FILE *)stream);
}
..........................................................................
contentFile = "Content.tmp";
FILE *fContent = fopen(contentFile.c_str(), "w+");
if (NULL == fContent)
{
return ERR;
}
CURL * curl = curl_easy_init();
if (curl == NULL)
{
return ERR;
}
char error[2048] = {0};
curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, error);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curl, CURLOPT_URL, curUrl.c_str());
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1); //automatolly jump
// curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 255);
/curl_easy_setopt(curl, CURLOPT_WRITEDATA, fContent);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, &writeCallBack);
//curl_easy_setopt(curl, CURLOPT_HEADER, 1);
// curl_easy_setopt(curl, CURLOPT_COOKIEFILE, cookieFile.c_str());
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, false);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postField.c_str());
curl_easy_setopt(curl, CURLOPT_POST, 5);
curlRet = curl_easy_perform(curl);
if (CURLE_OK == curlRet)
{
std::cout<< "success to perform curl. " << endl;
}
else
{
std::cout<< "fail to perform curl." <<"curlRet:"<<curlRet<< "err:"
<< error << endl;
}
curl_easy_cleanup(curl);
