Libcurl can achieve file upload, how do I implement file download? Urgent

hbw2025

The following code can upload the specified file in the specified directory to the specified directory on an HTTP server
curl_global_init (CURL_GLOBAL_ALL);
curl_formadd (&formpost,&lastptr, CURLFORM_COPYNAME, "file_name", CURLFORM_FILE, filepath, CURLFORM_END);
if (httpflag == 0) {
curl_formadd (&formpost,&lastptr, CURLFORM_COPYNAME, "buttom2", CURLFORM_COPYCONTENTS, "UPLOAD", CURLFORM_END);
} else if (httpflag == 1) {
curl_formadd (&formpost,&lastptr, CURLFORM_COPYNAME, "buttom1", CURLFORM_COPYCONTENTS, "UPLOAD", CURLFORM_END);
}
timevalue = conf_get_prop ("General", "UploadTimeout");
if (timevalue == NULL) {
TR_MALLOC (timevalue, 10);
TR_STRNCPY (timevalue, DEF_UPLOAD_TIME, 10);
}
curl = curl_easy_init ();
if (curl) {
// curl_easy_setopt (curl, CURLOPT_HEADER, TRUE);
curl_easy_setopt (curl, CURLOPT_URL, url);
curl_easy_setopt (curl, CURLOPT_USERPWD, userpwd);
curl_easy_setopt (curl, CURLOPT_POST, TRUE);
curl_easy_setopt (curl, CURLOPT_TIMEOUT, atoi (timevalue));
curl_easy_setopt (curl, CURLOPT_HTTPPOST, formpost);
res = curl_easy_perform (curl);
}


How to use Libcurl to realize the download of the specified file on the HTTP server to the specified directory? Urgent !!! Thank you

What else do I fix?
Now just execute it from the command line

Installed a lib library, you can use the command line
For example, the next file can be like this
system ("curl www.baidu.com/test.exe> ​​1.exe");

You can download a test.exe file from Baidu to the local computer and name it 1.exe

Halo ... the curl's documentation teaches how to download, it's nothing more than constructing an easy handle and then setting the request. .

Install an exe, set the path, and then system is fine
