问题描述

我正在尝试获取指向这些bit.ly重定向的URL链接.我试图用file_get_contents打开bit.ly链接，但它已经从重定向站点获取内容，但是如何获取其url?

I'm trying to get url links to those bit.ly redirects. I've tried to open bit.ly links with file_get_contents but it already gets content from redirected site, but how to get its url?

推荐答案

我不知道bit.ly API，这是原始方法:

I was unaware of the bit.ly API, here is the raw way to do it:

$context = array
(
    'http' => array
    (
        'method' => 'GET',
        'max_redirects' => 1,
    ),
);

@file_get_contents('http://bit.ly/cmUTtb', null, stream_context_create($context));

echo 'Redirect to: ' . str_replace('Location: ', '', $http_response_header[6]);
