如何通过Content-Disposition阅读xls文件返回：PHP附件

Question

当我访问链接时，例如： https : //demo.com/report? transType = xls，它将返回一个xls供我下载。 它是响应头：

HTTP/1.1 200 OK
Date: Thu, 16 Mar 2017 19:18:37 GMT
Server: IIS/4.0 (Windows XP)
Content-Disposition: attachment; filename*="utf-8''demo.xls
Vary: Accept-Encoding,User-Agent
Content-Length: 14848
Keep-Alive: timeout=10, max=1000
Connection: Keep-Alive

内容类型：text / html

如何使用PHP（CURL，Socket ...）将此文件下载到服务器？ 我尝试了CURL，但是它不起作用。 保存的文件无法读取:(这是我的代码：

$op = curl_init();
curl_setopt ($op, CURLOPT_URL, 'https://demo.com/report?transType=xls');
curl_setopt ($op, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($op, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($op, CURLOPT_TIMEOUT, 60);
curl_setopt ($op, CURLOPT_POST, 1); 
curl_setopt ($op, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($op, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($op, CURLOPT_BINARYTRANSFER, 1);

$response = curl_exec($op); 
@file_put_contents('saved.xls', $response);

请帮我 ：（

要使用curl在php中下载文件，您必须使用如下代码：

<?php
//File to save the contents to
$fp = fopen ('theFile.xls', 'w+'); 
$url = "https://demo.com/report?transType=xls";
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
//give curl the file pointer so that it can write to it
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$data = curl_exec($ch);//get curl response
//done
curl_close($ch);
fclose($fp);
?>
