Trailing slashes problem
提问by Zakaria
When I type this "http://example.com/Hello%20There/" , it displays the index page wich is : "http://example.com/Hello%20There/index.html" .
当我输入“ http://example.com/Hello%20There/”时，它显示的索引页面是：“ http://example.com/Hello%20There/index.html”。
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).
好吧，我想要做的是当用户输入“ http://example.com/Hello%20There”（所以就像第一个一样，只是它没有尾部斜杠）。
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”）时会停止 reg exp 进程。
I tried this reg exp:
我试过这个正则表达式：
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]
and also put:
并放：
DirectorySlash On
in the "mod_dir" module of Apache.
在 Apache 的“mod_dir”模块中。
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;$
所以，我的问题是： - 当用户键入一个不带斜杠的 url 时，如何告诉服务器添加一个斜杠；$

You can make a character optional by appending the ?quantifier to it like this:
您可以通过将?量词附加到字符来使字符可选，如下所示：
RewriteRule ^([^/]+)/?$ /index.html
Now both /foobarand /foobar/would be rewritten to /foobar/index.html.
现在，/foobar和/foobar/都将被重写为/foobar/index.html.
But it would be better if you use just one spelling, with or without the trailing slash, and redirect the other one:
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：
# remove trailing slash
RewriteRule (.+)/$ / [L,R=301]
# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .*[^/]$ // [L,R=301]
These rules either remove or add a missing trailing slash and do a permanent redirect.
这些规则删除或添加缺少的尾部斜杠并执行永久重定向。

I had the same problem, but I was using mod_alias to set up a subsite. Turns out, I needed to make a second alias without the trailing slash so that it would work correctly. Looked something like this:
我遇到了同样的问题，但我使用 mod_alias 来设置子站点。事实证明，我需要制作第二个不带斜杠的别名才能正常工作。看起来像这样：
Alias /forum/ "/var/www/forum"
Alias /forum "/var/www/forum"
<Directory "/var/www/forum">
Options FollowSymlinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
In Ubuntu, I had to edit the /etc/apache2/mods-enabled/alias.conffile with these lines, then restart apache. Couldn't find this answer anywhere on the web; I just stumbled onto it myself as mod_rewrite wasn't working and the DirectorySlash command didn't help either. I was appending a non-Drupal program as a subsite under a Drupal installation, which is what kicked off all this madness in the first place...
在 Ubuntu 中，我必须用这些行编辑/etc/apache2/mods-enabled/alias.conf文件，然后重新启动 apache。无法在网络上的任何地方找到此答案；我自己偶然发现了它，因为 mod_rewrite 不起作用并且 DirectorySlash 命令也没有帮助。我在 Drupal 安装下附加了一个非 Drupal 程序作为子站点，这首先引发了所有这些疯狂......

Don't use trailing slash to define an alias.
不要使用尾部斜杠来定义别名。
Both URLs http://example.com/myalias1and http://example.com/myalias1/would work fine.
URL http://example.com/myalias1和http://example.com/myalias1/都可以正常工作。
Example:
例子：
sudo vi /etc/apache2/apache2.conf
Alias /myalias1 "/path/to/folder1"
