使用lighttpd Web服务器时$_GET和$_POST变量不存在

我在 Windows 计算机上安装了 lighttpd Web 服务器，但遇到了一个问题：在 PHP 文件中没有定义 $_GET 和 $_POST 变量。

例如，我有这个简单的脚本（tmp.php）：

<?php

  echo "x: '" . $_GET ['x'] . "'<br />";

?>

当我转到地址：http://localhost/tmp.php?x=123时，

我得到这个错误消息：

Notice: Undefined index: x in /srv/www/htdocs/tmp.php on line 3 x: ''

当我将相同的文件放在公共托管上时，我得到：

x: '123'

另外 php 命令：

empty ($_GET)

返回 true。

所有 $_POST 变量也是如此。

我的 php.ini 文件中是否存在任何配置错误？

该命令：

print_r($_SERVER);

给出以下结果：

Array (
 [SERVER_SOFTWARE] => lighttpd/1.4.20
 [SERVER_NAME] => localhost
 [GATEWAY_INTERFACE] => CGI/1.1
 [SERVER_PROTOCOL] => HTTP/1.1
 [SERVER_PORT] => 80
 [SERVER_ADDR] => 0.0.0.0
 [REQUEST_METHOD] => GET
 [REDIRECT_STATUS] => 200
 [QUERY_STRING] => x=123
 [REQUEST_URI] => /tmp.php?x=123
 [REMOTE_ADDR] => 127.0.0.1
 [REMOTE_PORT] => 3150
 [CONTENT_LENGTH] => 0
 [SCRIPT_FILENAME] => /srv/www/htdocs/tmp.php
 [SCRIPT_NAME] => /srv/www/htdocs/tmp.php
 [DOCUMENT_ROOT] =>
 [SYSTEMROOT] => C:\WINNT
 [HTTP_ACCEPT] => */*
 [HTTP_ACCEPT_LANGUAGE] => en-gb
 [HTTP_USER_AGENT] => Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.1)
 [HTTP_ACCEPT_ENCODING] => gzip, deflate
 [HTTP_HOST] => localhost
 [HTTP_CONNECTION] => Keep-Alive
 [WINDIR] => C:\WINNT
 [PHP_SELF] => /srv/www/htdocs/tmp.php

 [REQUEST_TIME] => 1328287189
 [argv] => Array (
 [0] => /srv/www/htdocs/tmp.php )
 [argc] => 1 
)

因此值 x=123 存在于 $_SERVER['QUERY_STRING'] 和 $_SERVER['REQUEST_URI']< 中/code>，但我不知道如何获取它。

原文

I installed lighttpd web server on my Windows computer and I have a problem: in PHP files no $_GET and $_POST variables are defined.

For example I have this simple script (tmp.php):

<?php

  echo "x: '" . $_GET ['x'] . "'<br />";

?>

When I go to the address: http://localhost/tmp.php?x=123

I get this error message:

Notice: Undefined index: x in /srv/www/htdocs/tmp.php on line 3 x: ''

Whilst when I put the same file on public hosting I get:

x: '123'

Also the php command:

empty ($_GET)

returns true.

The same is for all $_POST variables.

Is there any misconfiguration in my php.ini file?

The command:

print_r($_SERVER);

gives the following result:

Array (
 [SERVER_SOFTWARE] => lighttpd/1.4.20
 [SERVER_NAME] => localhost
 [GATEWAY_INTERFACE] => CGI/1.1
 [SERVER_PROTOCOL] => HTTP/1.1
 [SERVER_PORT] => 80
 [SERVER_ADDR] => 0.0.0.0
 [REQUEST_METHOD] => GET
 [REDIRECT_STATUS] => 200
 [QUERY_STRING] => x=123
 [REQUEST_URI] => /tmp.php?x=123
 [REMOTE_ADDR] => 127.0.0.1
 [REMOTE_PORT] => 3150
 [CONTENT_LENGTH] => 0
 [SCRIPT_FILENAME] => /srv/www/htdocs/tmp.php
 [SCRIPT_NAME] => /srv/www/htdocs/tmp.php
 [DOCUMENT_ROOT] =>
 [SYSTEMROOT] => C:\WINNT
 [HTTP_ACCEPT] => */*
 [HTTP_ACCEPT_LANGUAGE] => en-gb
 [HTTP_USER_AGENT] => Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.0.3705; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.1)
 [HTTP_ACCEPT_ENCODING] => gzip, deflate
 [HTTP_HOST] => localhost
 [HTTP_CONNECTION] => Keep-Alive
 [WINDIR] => C:\WINNT
 [PHP_SELF] => /srv/www/htdocs/tmp.php
 [PATH_TRANSLATED] => /srv/www/htdocs/tmp.php
 [REQUEST_TIME] => 1328287189
 [argv] => Array (
 [0] => /srv/www/htdocs/tmp.php )
 [argc] => 1 
)

So the value x=123 exists in $_SERVER['QUERY_STRING'] and in $_SERVER['REQUEST_URI'], but I don't know how to get it.

首先让我们确保没有遗漏任何内容。

试试这个

<?php
    // test1.php
    print('GET: '); // First missing semicolon
    print_r($_GET);
    print('HTTP_GET_VARS: '); // Second missing semicolon
    print_r($HTTP_GET_VARS);
?>

其次尝试$_POST

制作一个简单的 html 表单并尝试发布它。

<?php
    // test2.php
    print_r($_POST);
?>
<form method="POST">
    <input type="text" name="myvar" />
    <input type="submit""/>
</form>

我知道这些听起来很愚蠢，但请尝试一下，以便我们排除它们。

最后你使用重写规则了吗？

查看 lighttpd.conf 中是否有提及“url.rewrite”。 Lighttpd 不会像 apache 那样尝试猜测 URL，如果您使用重写，您必须明确告诉它包含查询字符串。例如（重要的部分以粗体显示 - 将它们添加到您的重写中）。

url.rewrite = (
"^/([az]+)/([az]+)(?*)(.*)" => “/index.php?controller=$1&action=$2&**$4**”
）

Firstly lets make sure we're not missing something.

Try this

<?php
    // test1.php
    print('GET: '); // First missing semicolon
    print_r($_GET);
    print('HTTP_GET_VARS: '); // Second missing semicolon
    print_r($HTTP_GET_VARS);
?>

Secondly try $_POST

Make a simple html form and try to post it.

<?php
    // test2.php
    print_r($_POST);
?>
<form method="POST">
    <input type="text" name="myvar" />
    <input type="submit""/>
</form>

I know these sound silly, but please try them so we can rule them out.

Finally are you using rewrite rules?

Take a look in lighttpd.conf for any mention of 'url.rewrite'. Lighttpd doesn't try to guess the URL like apache, you have to specifically tell it to include the query string if your using rewrites. For example (The important bits are in bold - add them to your rewrites).

url.rewrite = (
"^/([a-z]+)/([a-z]+)(?*)(.*)" => "/index.php?controller=$1&action=$2&**$4**"
)
