PHP重定向与自定义页眉 [英] PHP Redirect with Custom Headers

问题描述

我写一个基本的授权系统，我与它挣扎了一下。这里涉及到两个文件 - 的index.php 和的login.php 。登录表单是pretty的简单（这里面的index.php ）：     

I am writing a basic authorization system and I am struggling with it a bit. There are two files involved - index.php and login.php. The login form is pretty simple (it's inside index.php):

<fieldset class="right">
    <label for="email">Email

        <input id="email" name="email" type="text" value=""/>
    </label>
    <label for="password">Password
        <input id="password" name="password" type="password" />
        <a href="#" onclick="$('#password-box').toggle();" >Forgot your password?<span></span></a>
    </label>
    <div class="btn-login"><button type="submit" value="Login"></button></div>
</fieldset>
</form>

在的login.php 内容：

<?php
//  Include the launcher file.
require_once('globals.php');
require_once(CORE . 'launcher.php');

//  Collect the information sent to us.
$mail = (isset($_POST['email'])) ? $_POST['email'] : '';
$password = (isset($_POST['password'])) ? $_POST['password'] : '';

$LoginError = false;
    // AUTHORIZATION STUFF HERE
if ($LoginError) {
    header('Status: 200');
    header('X-Test: test');
    header('Location: index.php');
    exit();
}

正如你所看到的，我送含万一有登录过程中发生错误的形式脚本自定义标题，在的index.php ，我使用 headers_list（），但我要送的头不是present在列表中。

As you can see, I'm sending a custom header to the script containing the form in case there was an error during signing in. In the index.php, I'm using headers_list(), but the header I'm sending is not present in the list.

是什么原因造成的？我试着 php_valueoutput_buffering，0在的.htaccess 文件，但没有成功。

What is causing that? I've tried with php_value "output_buffering" "0" in the .htaccess file, but no success.

更新 检查在铬后，正在接收标头由浏览器，但不提供在PHP

UPDATE After checking in Chrome, the header is being received by the browser, but is not available in PHP.

在此先感谢。

推荐答案

重定向是由它对应导航到给定的位置客户端发送到并处理：的index.php 。你不应该指望当它从服务器请求的index.php 的自定义头是由浏览器提供。

The redirect is sent to and processed by the client which responds by navigating to the given Location: index.php. You should not expect that the custom header is provided by the browser when it is requesting index.php from the server.

CLIENT                                    SERVER
 |------- POST login.php ------------------>|
 |                                          |
 |<- 200, Location: index.php, X-Test:test -| (this is where you send the header)
 |                                          |
 |------- GET index.php ------------------->| (no header from client to server)
