标头位置无法正常工作 [英] Header location not working properly

问题描述

我的网址为 http://www.website.ro/index .php？subiect = 10046& pag = 1 ＃1006 ，我在这里没有任何操作（< form action =method =提交后我检查一些输入字段，如果有任何错误，我想重定向。我使用以下代码：



  header（'Location：/index.php?subiect='.$_GET['subiect'] '&安培; PAG =' $ _ GET [ 'PAG']）;出口（）; 
  

但重定向包括＃1006 ，所以我的页面变成 http://www.website.ro/index.php?subiect=10046&pag=1 ＃1006

我试着在标题中更改位置：

  header（'Location：http://www.google.com'）;出口（）; 
  

需要我的页面是： http://www.google.com ＃1006

为什么要这样做？

我在第一行有 ob_start（），我试图删除它。没有效果。重定向stil后的网址＃1006 。

如果我的网址是 http://www.website.ro/index.php?subiect=10046&pag=1 ，我使用标题位置我没有问题，但如果url包含＃1006重定向后的url 片段标识符，并标识页面的一部分，即使该页面是从另一个URL检索的。

默认情况下，大多数浏览器在无论使用什么状态代码，都会发生3xx重定向。请参阅 URL片段和302重定向了解有关此问题的若干资源。

您可以返回一个包含片段标识符的URI（即使是空的）：

  header（'Location：http://www.google.com/#'）; 
  

然后用本草稿：

< blockquote>

例外情况是，返回的URI已经有一个片段
标识符。在这种情况下，原始片段标识符MUST NOT不会被
添加到它。

您也可以更改片段标识符 onclick 使用Javascript。

My URL is http://www.website.ro/index.php?subiect=10046&pag=1#1006, and i have a form here with no action (<form action="" method="post">).

After submit I'm checking some input fields and if there is any error, I want to redirect. I use this code:

header('Location: /index.php?subiect='.$_GET['subiect'].'&pag='.$_GET['pag']); exit();

But the redirect includes #1006 so my page becomes http://www.website.ro/index.php?subiect=10046&pag=1#1006

I tried to change location in the header with:

header('Location: http://www.google.com'); exit();

The page where takes me is : http://www.google.com#1006

Why does it do this?

I have ob_start() at first line and i tried to deleted it. No effect. The url after redirect stil has #1006.

If my url is http://www.website.ro/index.php?subiect=10046&pag=1 and i use header location i don't have problems, but if the url contains #1006 the url after redirect contains to.

解决方案

The part after the # is called the fragment identifier and identifies a part of the page, even if the page is retrieved from another URL.

By default most browsers keep the fragment identifier when a 3xx redirect occurs, regardless of what status code is used. See URL Fragment and 302 redirects for several resources about the matter.

You can return an URI that contains a fragment identifier itself (even an empty one):

header('Location: http://www.google.com/#');

Then that one will be used instead, as specified in this draft:

The exception is when a returned URI already has a fragment identifier. In that case the original fragment identifier MUST NOT be not added to it.

You could also change the fragment identifier onclick using Javascript.
