htaccess的沉默重定向到子目录：子目录显示时没有尾随'/'

问题描述：

我已经挖高，围绕谷歌和计算器低，试图找出我的问题，尝试了无数的解决方案，但没有完全奏效。

I have dug high and low around Google and StackOverflow to try and figure out my problem, trying countless solutions but nothing has completely worked.

我在寻找移动主域名的web根我的服务器上的一个子目录。我现在有一台服务器的路径到我的网站根目录：

I'm looking to move the web root of the main domain on my server to a sub-directory. What I have currently for a server path to my web root:

/home/user/public_html/MyWebFilesHere

我在寻找什么有：

What I'm looking to have:

/home/user/public_html/subdir/MyWebfilesHere

当我浏览到mydomain.com，应该有，虽然没有明显的区别（即子目录重定向后不可见）。

When I browse to mydomain.com, there should be no visible difference though (i.e. "subdir" not visible after redirect).

不幸的是，我仅限于使用.htaccess文件纯粹是这样，因为我在共享主机和不具备访问Apache的配置文件，这样的。 ：（

Unfortunately, I am restricted to doing this purely with a .htaccess file since I'm on shared hosting and don't have access to Apache config files and such. :(

我现在有在我的public_html的.htaccess是：

What I currently have in my .htaccess in public_html is:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$
RewriteCond %{REQUEST_URI} !^/subdir/
RewriteRule ^(.*)$ /subdir/$1 [L]

本成功重定向所有查询到子目录，但是有一个很奇怪的问题。如果我去

This successfully redirects all queries to the sub-directory, however there's a really weird issue. If I go to

mydomain.com/Contact/

它的伟大工程，重定向查询到的路径/子目录/联系人/但只留下地址栏。如果我去

it works great, redirecting the query to the path /subdir/Contact/ but leaving the address bar alone. If I go to

mydomain.com/Contact

（注意没有尾随'/'的），虽然，是什么在地址栏中显示为

(Note the lack of a trailing '/') though, what shows in the address bar is

mydomain.com/subdir/Contact/

这不是我想要的，因为子目录是显示。

which isn't what I want since "subdir" is showing.

有关我的现场实际工作的例子，尝试浏览到

For a working example on my actual site, try browsing to

colincwilliams.com/Contact/

相比

colincwilliams.com/Contact

难道你们对如何默默带或不带斜线，使这项工作任何想法？

Do you guys have any ideas on how to make this work silently both with and without a trailing slash?

答

这是可能发生的，因为这会自动将浏览器重定向如果目录的请求缺少斜线，以同样的事情mod_dir（模块的与的一个斜线，请参见 DirectorySlash指令在mod_dir

This is probably happening because mod_dir (the module that automatically redirects the browser if a request for a directory is missing a trailing slash to the same thing with a trailing slash. See the DirectorySlash directive in mod_dir

这是怎么回事是：

  1. 您请求： mydomain.com/Contact
  2. 在mod_dir不碰这个，因为 /联系方式不是目录
  3. /联系方式被改写为 /子目录/联系方式和内部的重定向
  4. mod_dir看到了 /子目录/联系方式是一个目录，缺少结尾的斜线所以它的浏览器重定向到 mydomain.com/subdir/Contact /
  5. 所以，现在，您的浏览器的地址栏中有/子目录/在里面。
  1. You request: mydomain.com/Contact
  2. mod_dir doesn't touch this since /Contact isn't a directory
  3. /Contact gets rewritten to /subdir/Contact and internally redirected
  4. mod_dir sees that /subdir/Contact is a directory and missing the trailing slash so it redirects the browser to mydomain.com/subdir/Contact/
  5. So now, your browser's location bar has the /subdir/ in it.

您可以在你的.htaccess中添加 DirectorySlash关闭关闭mod_dir从重定向。但是，如果你想要的目录有尾随斜线，您可以添加一个单独的条件吧。根据你已经有了，我们可以把它扩展到这一点：

You can add DirectorySlash off in your .htaccess to turn off mod_dir from redirecting. But if you want directories to have trailing slashes, you can add a separate condition for it. Based on what you already have, we can expand it to this:

RewriteEngine on

# Has a trailing slash, don't append one when rewriting
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$
RewriteCond %{REQUEST_URI} !^/subdir/
RewriteCond %{THE_REQUEST} ./\ HTTP/1\.[01]$ [OR]
# OR if it's a file that ends with one of these extensions
RewriteCond %{REQUEST_URI} \.(php|html?|jpg|gif|css)$
RewriteRule ^(.*)$ /subdir/$1 [L]

# Missing trailing slash, append one
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$
RewriteCond %{REQUEST_URI} !^/subdir/
RewriteCond %{THE_REQUEST} [^/]\ HTTP/1\.[01]$
# But only if it's not a file that ends with one of these extensions
RewriteCond %{REQUEST_URI} !\.(php|html?|jpg|gif|css)$
RewriteRule ^(.*)$ /subdir/$1/ [L]

请注意：！我改变了 ^ / MYDOMAIN / 到 ^ /子目录/ ，想通这是一个错字原因无它，mod_rewrite的将内部无限循环（FOO - > /子目录/富 - > /子目录/子目录/富 - > /子目录/子目录/子目录/富等）。如果我是错的，你可以改回。

Note: I changed !^/mydomain/ to !^/subdir/, figured it was a typo because without it, mod_rewrite would loop internally indefinitely (foo -> /subdir/foo -> /subdir/subdir/foo -> /subdir/subdir/subdir/foo, etc). If I got that wrong, you can change it back.

编辑：看我补充的RewriteCond的匹配对 \（PHP | HTML | JPG | GIF | CSS？）。这些是获得通过没有得到尾随斜线的文件扩展名添加。您可以添加/删除，以满足您的需求。

See my additions of RewriteCond's matching against \.(php|html?|jpg|gif|css). These are the file extensions that get passed through without getting trailing slashes added. You can add/remove to suit your needs.
