使用cURL下载文件 [英] Download a file with cURL

问题描述

我想用cURL下载一个文件。我收到了文件所在的URL，但url在到达文件之前进行重定向。由于某种原因，当我使用cURL访问URL时，我总是收到注销页面，但是当我直接在浏览器中输入URL时，文件只是按照它应该下载的。

I am trying to download a file with cURL. I have received an URL where the file is located, but the url makes an redirect before reaching the file. For some reason I always receive the logout page when I access the URL with cURL, but when I enter the URL directly in my browser the file just downloads as it is supposed to. The file that should be downloaded is a RAR file, but instead of the file I get the incorrect login page.

这是目前的代码：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
$result = curl_exec($ch); 

curl_close($ch);

print_r($result);

正如你所看到的，我使用下面的代码来允许重定向：

As you can see I am using the following code to allow the redirects:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

但如果我使用上述代码，我总是从网站收到错误的登录页面。谁能看到我在这里做错了？

But I always receive the incorrect login page from the website if I use the above code. Can anyone see what I am doing wrong here ?

这是我从服务器获得的响应：

This is the reponse I get from the server:

推荐答案

p>

Try with this code

$url = "www.abc.com/xyz";//your url will come here
$fp = fopen ('test.txt', 'w+');
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch); 
curl_close($ch);
fclose($fp);
