[질문] libcurl을 사용해서 파란에 로긴을 하고 싶습니다.. 소스좀 봐주세요~~

int main(int argc, char** argv)
{
	const char* strTargetUrl = "http://main.paran.com/mainAction.do?method=paranMainLogin";
	const char* strPostFilds = "http%3A%2F%2Fmailsms.paran.com&wbSurl=http%3A%2F%2Fmailsms.paran.com&wbUserid=아이디&wbDomain=paran.com&wbPasswd=비밀번호&wbSecure=1&x=49&y=10";
	const char* strReferer = "http://mailsms.paran.com/";
 
	curl_global_init( CURL_GLOBAL_ALL ) ; 
 
	CURL* ctx = curl_easy_init() ; 
 
	if( NULL == ctx ){ 
		std::cerr << "Unable to initialize cURL interface" << std::endl ; 
		return( ERROR_CURL_INIT ) ; 
	} 
 
	curl_easy_setopt(ctx, CURLOPT_HEADER, 1);
	curl_easy_setopt(ctx, CURLOPT_POST, 1);
	curl_easy_setopt(ctx, CURLOPT_POSTFIELDS, strPostFilds);
	curl_easy_setopt(ctx, CURLOPT_REFERER, strReferer) ;
	curl_easy_setopt(ctx, CURLOPT_TIMEOUT, 100);
	curl_easy_setopt(ctx, CURLOPT_COOKIEJAR, "D:\\");
	curl_easy_setopt(ctx, CURLOPT_COOKIEFILE, "D:\\XXX.txt");
	curl_easy_setopt(ctx , CURLOPT_WRITEDATA , stdout); 
	curl_easy_setopt(ctx, CURLOPT_URL, strTargetUrl);
	curl_slist* responseHeaders = NULL ;
	responseHeaders = curl_slist_append( responseHeaders , "User-Agent: Mozilla" ) ; 
	curl_easy_setopt(ctx , CURLOPT_HTTPHEADER , responseHeaders) ; 
	curl_easy_setopt(ctx, CURLOPT_VERBOSE, 1);
 
	std::cout << "- - - BEGIN: response - - -" << std::endl ; 
	CURLcode rc = curl_easy_perform(ctx) ; 
	std::cout << "- - - END: response - - -" << std::endl ; 
 
	if( CURLE_OK != rc ){ 
		std::cerr << "Error from cURL: " << curl_easy_strerror( rc ) << std::endl ; 
	} 
 
	curl_easy_cleanup(ctx) ; 
	curl_global_cleanup() ; 
	std::exit( 0 ) ; 
	return 0;
