htaccess ErrorDocument 404重定向不工作 [英] htaccess ErrorDocument 404 redirect not working

问题描述

请告诉我为什么这不工作。这是工作，但莫名地决定停止工作。
在php中，如果页面不是这样的话，我发出404。

  if（checkPageExists（$ escaped_url_page_name） ）{
 header（'HTTP / 1.1：200 OK'）; 
} else {
 header（HTTP / 1.0 404 Not Found）; 
死
} 
  

我的htaccess是

  php_flag magic_quotes_gpc Off 
 
 RewriteEngine On 
 RewriteCond％{REQUEST_FILENAME}！-f 
 RewriteCond％{REQUEST_FILENAME}！-d 
 RewriteRule ^（。*）$ /index.php?/$1 [L] 
 
 ErrorDocument 404 /404.php 
  

404页面在根目录下，名称为404.php。为什么五分钟前没有工作，没有任何改变。我已经用fiddler测试了这个页面，它确实是抛出了404的，但重定向没有发生。我实现了友好的URL，但我不会认为这会影响它，因为htaccess中的/是指我想到的网站的物理根。感谢提前。

解决方案

我有一个类似的问题一次 - 当PHP抛出一个404标题时，Apache一般不会404页面。 （编辑：这可能与PHP是否输出任何文本有关，我还没有真正尝试过）。如果您检查浏览器中的标题，您可以看到404标题有效，即使页面为空

我不确定自动化解决方案，但是我刚刚做了一个 http_error（$ code）函数打印我的自定义错误页面，并随着 header（）一起调用，只要我的代码手动触发了一个404.然后我绑定了一些代码到 ErrorDocument 仅调用 http_error ：

  ErrorDocument 404 index.php？http_error = 404 
 ErrorDocument 403 index.php？http_error = 403 
  

...等等。

Please tell me why this is not working. It was working but has inexplicably decided to stop working. In php I issue a 404 if the page is not found like so.

if(checkPageExists($escaped_url_page_name)){
header('HTTP/1.1: 200 OK');
}else{
header("HTTP/1.0 404 Not Found");
die;
}

My htaccess is

php_flag magic_quotes_gpc Off

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]

ErrorDocument 404 /404.php

The 404 page is on the root and is name 404.php. Why would that not work when five minutes ago it was and nothing has changed. I have tested the page with fiddler and it is indeed throwing the 404's but the redirect is not happening. I have friendly urls implemented, but I would not think this affects it as the "/" in the htaccess refers to the physical root of the site I thought. Thanks in advance.

解决方案

I had a similar issue once - when PHP throws a 404 header, Apache generally won't make a 404 page for it. (Edit: It probably has to do with whether PHP outputs any text. I haven't really experimented with it much.) If you check the headers in your browser, you can see that the 404 header worked, even if the page is blank.

I'm not sure about an automated solution, but I just made an http_error($code) function that prints my custom error page and called that along with header() whenever my code manually triggered a 404. Then I bound a bit of code to ErrorDocument that calls http_error only:

ErrorDocument 404 index.php?http_error=404
ErrorDocument 403 index.php?http_error=403

...and so on.
