When sending curl requests, add

//获取响应的消息头curl_setopt($curl, CURLOPT_HEADER, 1);curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);

Parse HTTP header to Content-Disposition get file name

$tmpInfo = curl_exec($curl);list($headers, $body) = explode("\r\n\r\n", $tmpInfo, 2);$header_array = explode("\n", $headers[0]);foreach($header_array as $header_value) {    $header_pieces = explode(':', $header_value);    if(count($header_pieces) == 2) {        $headers[$header_pieces[0]] = trim($header_pieces[1]);    }}$file_name = $headers['Content-Disposition'];$file_type = $headers['Content-Type'];$file_content = $body;

You can refer to the above code, if not Content-Disposition , you need special treatment, you can see where the other person returns the file name.
Save file only need to $file_content write open file handle

curl -O -d "key=val" urlThe returned content is saved as a file of the same name.

Are you going to return the "file name" or the file content? If you want the file name, check the "content-disposition" header first, without using the filename on the URL. If you want the contents of the file, write a write function and pass it to curl.
