通过 C 中的 curl 获取链接用户的帐户信息

#include <stdio.h>
#include <curl/curl.h>

int main (int argc, char *argv[])
{
      CURL *curl;
      CURLcode res;

      /* In windows, this will init the winsock stuff */ 
      curl_global_init(CURL_GLOBAL_ALL);

      curl = curl_easy_init();
      if(curl) {

            printf ("Running curl test.\n");

            struct curl_slist *headers=NULL; /* init to NULL is important */
            headers = curl_slist_append(headers, "Authorization: Bearer <ACCESS_TOKEN>");
            headers = curl_slist_append(headers, "Content-Type: application/json");
            curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);

            curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "null");

            /* Perform the request, res will get the return code */ 
            res = curl_easy_perform(curl);

            /* Check for errors */ 
            if(res != CURLE_OK)
                  fprintf(stderr, "curl_easy_perform() failed: %s\n",
