示例
#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);
/* get a curl handle */
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:");
headers = curl_slist_append(headers, "Dropbox-API-Arg: {\"path\":\"/test.txt\"}");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl, CURLOPT_URL, "https://content.dropboxapi.com/2/files/download");
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "");
/* 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",
curl_easy_strerror(res));
/* always cleanup */
curl_easy_cleanup(curl);
printf ("\nFinished curl test.\n");
}
curl_global_cleanup();
printf ("Done!\n");
return 0;
