先说一个成功的示例

比如执行命令行代码 curl.exe http://baidu.com --libcurl libcurl.txt，生成的 libcurl.txt 内容如下：

libcurl.txt

Code: Select all

/********* Sample code generated by the curl command line tool **********
 * All curl_easy_setopt() options are documented at:
 * http://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_URL, "http://baidu.com");
  curl_easy_setopt(hnd, CURLOPT_NOPROGRESS, 1L);
  curl_easy_setopt(hnd, CURLOPT_USERAGENT, "curl/7.31.0");
  curl_easy_setopt(hnd, CURLOPT_MAXREDIRS, 50L);
  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

  */

  ret = curl_easy_perform(hnd);

  curl_easy_cleanup(hnd);
  hnd = NULL;

  return (int)ret;
}
/**** End of sample code ****/

把 libcurl.txt 里面的代码转成 ahk 代码是这样：

Code: Select all

#include ../cURL.new

if ret := curl_global_init(){
	msgbox % "Global initialization error: " ret
	exitapp
}

msgbox % curl_version()

hnd := curl_easy_init()
curl_easy_setopt(hnd, "CURLOPT_URL", "http://baidu.com")
curl_easy_setopt(hnd, "CURLOPT_NOPROGRESS", "1L")
curl_easy_setopt(hnd, "CURLOPT_USERAGENT", "curl/7.31.0")
curl_easy_setopt(hnd, "CURLOPT_MAXREDIRS", "50L")
curl_easy_setopt(hnd, "CURLOPT_TCP_KEEPALIVE", "1L")

MsgBox, % curl_easy_perform(hnd) ; 返回 0 表示成功

curl_easy_cleanup(hnd)
cURL_Global_Cleanup()
exitapp

能否增加一个下载文件到变量的示例?
