PHP，如何重定向/转发HTTP请求与标题和正文？ [英] PHP, How to Redirect/Forward HTTP Request with header and body?

问题描述

我有一个PHP页面，main.php是在服务器1上。

I have a PHP page, main.php which is on server 1.

我有一个PHP页面main.php（相同的页面，不同的代码） 2。

I have a PHP page main.php (same page, different code) on server 2.

main.php是一个WebService。

main.php is a WebService.

我想转发完整的HTTP请求服务器1，到服务器2，
，使得当用户向main.php（服务器1）发送HTTP请求时，它将从服务器2上的main.php获得响应。

I would like to forward the full HTTP request made to server 1, to server 2, so that when a user sends an HTTP request to main.php (server 1), it would get the response from main.php on server 2.

我希望对服务器2的请求与对服务器1的请求完全一样。

I would like the request made to server 2 to be exactly like the original request to server 1.

我通过以下方式获取Http请求数据：

I take the Http Request data via:

$some_param  = $_REQUEST['param']
$body =file_get_contents('php://input');

并假设我有

$server1_url = "11111";
$server2_url = "22222";

这样做的动机是，我有一个生产服务器和临时服务器，我想直接一些流量到新服务器以测试临时服务器上的新功能。

The motivation for this is, i have a production server and a staging server, i would like to direct some traffic to the new server to test the new functionality on the staging server.

如何重定向所有数据的请求或克隆完整的请求，发送它到新的服务器并返回新的响应？

How do i redirect the request with all the data or "cloning" the full request, sending it to the new server and returning the new response?

感谢您的帮助！

php curl，但我不明白它是如何工作的，我发现各种答案，但没有转发请求参数和身体。

p.s i tried using php curl, but i dont understand how it works, also i found all kinds of answers, but none forward the Requests params and the body.

再次感谢！ >

Again thanks!

推荐答案

这是我发现的解决方案（可能会更好）

this is the solution i have found (there might be better)

 public static function getResponse ($url,$headers,$body)
    {
        $params = '?' . http_build_query($headers);

        $redirect_url = $url . $params;

        $ch = curl_init($redirect_url);

        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($ch);

        if (!isset($response))
            return null;
        return $response;
    }
