htaccess的重写规则的工作原理，但URL不会在地址栏有什么变化？ [英] .htaccess RewriteRule works but the URL isn't changing in the address bar?

问题描述

我一直在拉我的头发试图弄清楚这一点，但没有什么工作。我有一个网页在 mysite.com/test.php 我想做一个简单的URL重写，并将其更改为 mysite.com/testRewrite / 的code到不实现这个应该是：

I have been pulling my hair trying to figure this out but nothing is working. I have a webpage at mysite.com/test.php I want to do a simple URL rewrite and change it to mysite.com/testRewrite/ The code to do implement this should be:

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^testRewrite/$ test.php [NC,L]

无论出于何种原因，它只是不工作。当你去到新的URL。 - mysite.com/testRewrite / 它的工作原理

不过，如果你在原来的网址键入 mysite.com/test.php 它不会将地址更改为在浏览器新的URL。

However, if you type in the original URL mysite.com/test.php it doesn't change the address to the new URL in the browser.

推荐答案

mod_rewrite的将不会自动实施从重写的URL重定向浏览器。你只需把规则说：如果有人问 / testRewrite / ，在内部将其更改为 /test.php 。它什么都不做来处理 /test.php 实际的要求，这就是为什么当您试图访问的 mysite.com/test.php 时，为您提供了 /test.php 。

mod_rewrite won't automatically enforce redirecting browsers from rewritten URLs. The rule you have simply says "if someone asks for /testRewrite/, internally change it to /test.php". It does nothing to handle actual requests for /test.php, which is why when you try to access mysite.com/test.php, it gives you /test.php.

现在，与mod_rewrite的问题是，如果你只添加的规则：

Now, the problem with mod_rewrite is if you simply add that rule:

RewriteRule ^test.php$ /testRewrite/ [L,R=301]

这将重定向浏览器时，它要求 /test.php 到 / testRewrite / ，第一条规则重定向浏览器之后将被应用，并且URI被改写为 /test.php ，然后它的需要对整个重写引擎的和上述规则被再次应用，从而将浏览器重定向，因此第一条规则重写到 /test.php ，和上面的规则再次重定向，等等，等等你得到一个重定向循环。你必须添加一个条件，以确保实际请求 /test.php 浏览器*，而且它不是多数民众赞成通过重写引擎被搅动的URI：

which will redirect the browser when it asks for /test.php to /testRewrite/, the first rule will be applied after the browser redirects, and the URI gets rewritten to /test.php, then it goes back through the entire rewrite engine and the above rule gets applied again, thus redirecting the browser, thus the first rule rewrites to /test.php, and the above rule redirects again, etc. etc. You get a redirect loop. You have to add a condition to ensure the browser *actually requested /test.php and that it's not a URI that's been churned through the rewrite engine:

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /test\.php [NC]
RewriteRule ^test.php$ /testRewrite/ [L,R=301]

这样一来，301重定向发生后，这条规则将不会被再次应用，因为实际的请求将 GET / testRewrite / HTTP / 1.1 ，条件将无法实现。

This way, after the 301 redirect happens, this rule won't get applied again because the actual request will be GET /testRewrite/ HTTP/1.1, and the condition won't be met.
