尾随斜线问题 [英] Trailing slashes problem

问题描述

当我输入http://example.com/Hello%20There/"时，它显示索引页面是:http://example.com/Hello%20There/index.html" .

When I type this "http://example.com/Hello%20There/" , it displays the index page wich is : "http://example.com/Hello%20There/index.html" .

好吧，我想做的是当用户输入http://example.com/Hello%20那里"(所以就像第一个一样，只是它没有尾部斜杠).

Well, what I want to do is when the user types "http://example.com/Hello%20There" (so like the first one except it doesn't have a trailing slash).

我尝试了很多东西，特别是正则表达式，但没有任何效果，因为我认为服务器在找到空格(URL 中的%20")时停止 reg exp 进程.

I tried many things and specially regular expressions, but nothing works because I think that the server stops the reg exp process when he finds a space ("%20" in the URL).

我试过这个正则表达式:

I tried this reg exp:

Options +FollowSymLinks 
rewriteEngine On rewriteCond %{REQUEST_URI} ^(.*)\ (.*html)$ 
rewriteRule ^.*$ %1-%2 [E=space_replacer:%1-%2] 
rewriteCond %{ENV:space_replacer}!^$ 
rewriteCond %{ENV:space_replacer}!^.*\ .*$ 
rewriteRule ^.*$ %{ENV:space_replacer} [R=301,L] 

并加上:

DirectorySlash On 

在 Apache 的mod_dir"模块中.

in the "mod_dir" module of Apache.

所以，我的问题是:- 当用户输入 url 时如何告诉服务器添加尾部斜杠没有尾部斜杠;$

So, my question is: - How to tell to the server to add a trailing slash when the user types an url without a trailing slash;$

推荐答案

您可以通过在字符后面附加 ? 量词来使字符可选，如下所示:

You can make a character optional by appending the ? quantifier to it like this:

RewriteRule ^([^/]+)/?$ $1/index.html

现在 /foobar 和 /foobar/ 都将被重写为 /foobar/index.html.

Now both /foobar and /foobar/ would be rewritten to /foobar/index.html.

但是如果您只使用一种拼写(带或不带斜杠)并重定向另一种拼写会更好:

But it would be better if you use just one spelling, with or without the trailing slash, and redirect the other one:

# remove trailing slash
RewriteRule (.+)/$ /$1 [L,R=301]

# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .*[^/]$ /$1/ [L,R=301]

这些规则删除或添加缺少的尾部斜杠并执行永久重定向.

These rules either remove or add a missing trailing slash and do a permanent redirect.
