如何在 PHP 中代理另一个页面

How to proxy another page in PHP(如何在 PHP 中代理另一个页面)

问题描述

我正在寻找用 PHP 代理页面的最快和最简单的方法.我不希望用户被重定向，我只希望我的脚本返回与另一个远程 URL 相同的内容、响应代码和标头.

I'm looking for the fastest and easiest way to proxy a page in PHP. I don't want the user to be redirected, I just want my script to return the same content, response code and headers as another remote URL.

推荐答案

echo file_get_contents('proxypage');那行得通吗?

第一个答案有点短，我不相信它会按照您的意愿处理标题.

First answer was a bit short, and I don't believe it will handle headers as you would like.

但是你也可以这样做:

function get_proxy_site_page( $url )
{
    $options = [
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => true,     // return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    ];

    $ch = curl_init($url);
    curl_setopt_array($ch, $options);
    $remoteSite = curl_exec($ch);
    $header = curl_getinfo($ch);
    curl_close($ch);

    $header['content'] = $remoteSite;
    return $header;
}

这将返回一个包含大量远程页面信息的数组.$header['content'] 将包含网站的内容和标题，$header[header_size] 将包含该标题的长度，因此您可以使用 substr 将它们分开.

This will return you an array containing lots of information on the remote page. $header['content'] will have both the content of the website and the headers, $header[header_size] will contain the length of that header so you can use substr to split those up.

然后只需要使用echo和header来代理页面即可.

Then it's just a matter of using echoand header to proxy the page.
