Using libcurl to create a valid POST
- by Haraldo
static int get( const char * cURL, const char * cParam ) {
CURL *handle;
CURLcode result;
std::string buffer;
char errorBuffer[CURL_ERROR_SIZE];
//struct curl_slist *headers = NULL;
//headers = curl_slist_append(headers, "Content-Type: Multipart/Related");
//headers = curl_slist_append(headers, "type: text/xml");
// Create our curl handle
handle = curl_easy_init();
if( handle ) {
curl_easy_setopt(handle, CURLOPT_ERRORBUFFER, errorBuffer);
//curl_easy_setopt(handle, CURLOPT_HEADER, 0);
//curl_easy_setopt(handle, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(handle, CURLOPT_POST, 1);
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_USERAGENT, "libcurl-agent/1.0");
curl_easy_setopt(handle, CURLOPT_URL, cURL);
result = curl_easy_perform(handle);
curl_easy_cleanup(handle);
}
if( result == CURLE_OK ) {
return atoi( buffer.c_str() );
}
return 0;
}
Hi there, first of all I'm having trouble debugging this in visual studio express 2008 so I'm unsure what buffer.c_str() might actually be returning but I am outputting 1 or 0 to the web page being posted to. Therefore I'm expecting the buffer to be one or the other, however I seem to only be returning 0 or equivalent.
Does the code above look like it will return what I expect or should my variable types be different? The conversion using "atoi" may be an issue.
Any thought would be much appreciated.
