Проблема с CURLOPT_WRITEDATA ⇐ C++

[Anonymous]

Я использую libcurl для получения данных JSON с помощью запроса GET с веб-сервера.

Это мой пример кода:

Код: Выделить всё

char *DownloadedResponse;

static int writer(char *data, size_t size, size_t nmemb, char *buffer_in)
{
if (buffer_in != NULL)
{
buffer_in = new char[size*nmemb];
strcpy(buffer_in,data);
DownloadedResponse = buffer_in;

return size * nmemb;

}

return 0;

}

char * DownloadJSON(string URL)
{
CURL *curl;
CURLcode res;
struct curl_slist *headers=NULL;

curl_slist_append(headers, "Accept: application/json");
curl_slist_append( headers, "Content-Type: application/json");
curl_slist_append( headers, "charsets: utf-8");
curl = curl_easy_init();

if (curl)
{
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl, CURLOPT_URL, URL.c_str());
curl_easy_setopt(curl, CURLOPT_HTTPGET,1);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl,CURLOPT_WRITEFUNCTION,writer);

res = curl_easy_perform(curl);

if (CURLE_OK == res)
{

char *ct;
res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);

if((CURLE_OK == res) && ct)
{
cout
