从curl命令获取libcurl的用法

libcurl的用法参数太多 有时候弄不好 可以先用curl命令实现了 然后获取相应的libcurl代码

比如要上传文件

curl -T d:/h.txt http://demo.xudp.cn/up/

下面获取相应的代码

curl --libcurl d:/curl.txt -T d:/h.txt http://demo.xudp.cn/up/

相应的代码就放到d:/curl.txt里面了

/********* Sample code generated by the curl command line tool **********

 * All curl_easy_setopt() options are documented at:

 * https://curl.haxx.se/libcurl/c/curl_easy_setopt.html

 ************************************************************************/

#include <curl/curl.h>

int main(int argc, char *argv[])

{

  CURLcode ret;

  CURL *hnd;

  hnd = curl_easy_init();

  curl_easy_setopt(hnd, CURLOPT_BUFFERSIZE, 102400L);

  curl_easy_setopt(hnd, CURLOPT_INFILESIZE_LARGE, (curl_off_t));

  curl_easy_setopt(hnd, CURLOPT_URL, "http://demo.xudp.cn/up/h.txt");

  curl_easy_setopt(hnd, CURLOPT_NOPROGRESS, 1L);

  curl_easy_setopt(hnd, CURLOPT_UPLOAD, 1L);

  curl_easy_setopt(hnd, CURLOPT_USERAGENT, "curl/7.65.3");

  curl_easy_setopt(hnd, CURLOPT_MAXREDIRS, 50L);

  curl_easy_setopt(hnd, CURLOPT_HTTP_VERSION, (long)CURL_HTTP_VERSION_2TLS);

  curl_easy_setopt(hnd, CURLOPT_HTTP09_ALLOWED, 1L);

  curl_easy_setopt(hnd, CURLOPT_CAINFO, "C:\\Windows\\system32\\curl-ca-bundle.crt");

  curl_easy_setopt(hnd, CURLOPT_SSH_KNOWNHOSTS, "C:\\Users\\Administrator\\AppData\\Roaming/_ssh/known_hosts");

  curl_easy_setopt(hnd, CURLOPT_TCP_KEEPALIVE, 1L);

  /* Here is a list of options the curl code used that cannot get generated

  ret = curl_easy_perform(hnd);

  hnd = NULL;

  return (int)ret;

}
