    这是一个创建于 1833 天前的主题,其中的信息可能已经有所发展或是发生改变。

    如果在使用 curl 命令行的时候加上 --libcurl 参数,就可以生成用 libcurl 完成本次请求的 C 语言源代码文件。比如:

    curl --libcurl example.c https://www.example.org/
    

    然后获得的 example.c 是这样的:

    /********* 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_URL, "https://www.example.org/");
      curl_easy_setopt(hnd, CURLOPT_NOPROGRESS, 1L);
      curl_easy_setopt(hnd, CURLOPT_USERAGENT, "curl/7.60.0");
      curl_easy_setopt(hnd, CURLOPT_MAXREDIRS, 50L);
      curl_easy_setopt(hnd, CURLOPT_HTTP_VERSION, (long)CURL_HTTP_VERSION_2TLS);
      curl_easy_setopt(hnd, CURLOPT_TCP_KEEPALIVE, 1L);
    
      /* Here is a list of options the curl code used that cannot get generated
         as source easily. You may select to either not use them or implement
         them yourself.
    
      CURLOPT_WRITEDATA set to a objectpointer
      CURLOPT_INTERLEAVEDATA set to a objectpointer

      CURLOPT_HEADERDATA set to a objectpointer
    
      */
    
      ret = curl_easy_perform(hnd);
    
      curl_easy_cleanup(hnd);
      hnd = NULL;
    
      return (int)ret;
    }

    要是再结合 Chrome 的 copy as cURL 就更好玩了
