apache mod_rewrite 代理 RewriteRule 不起作用

mod_rewrite proxy RewriteRule not working

提问by Lightbeard

I need to send all requests for the directory home/alphauser to backend/alphauser, but not requests to files inside the home/alphauser directory. For example:

我需要将对目录 home/alphauser 的所有请求发送到 backend/alphauser，而不是对 home/alphauser 目录中的文件的请求。例如：

http://home/alphauser            ->   http://backend/alphauser
http://home/alphauser/           ->   http://backend/alphauser
http://home/alphauser/icon.png   ->   http://home/alphauser/icon.png
http://home/alphauser/index.html ->   http://home/alphauser/index.html

I created an ".htaccess" file in the home/alphauser/ directory with the following:

我在 home/alphauser/ 目录中创建了一个“.htaccess”文件，内容如下：

RewriteEngine on
RewriteRule ^$ http://backend/alphauser [P]

mod_rewrite allows for access to files inside the home/alphauser/ directory as expected, but when the directory itself is requested either with or without the slash:

mod_rewrite 允许按预期访问 home/alphauser/ 目录中的文件，但是当请求目录本身时，带或不带斜杠：

http://home/alphauser
http://home/alphauser/

..the browser (firefox) presents a file download popup that states:

.. 浏览器 (firefox) 会显示一个文件下载弹出窗口，说明：

You have chosen to open a file which
is a: httpd/unix-directory

The contents of the file is the proper html from backend/alphauser (which is the url pattern to a JSP) so the payload returned is correct. It seems as though apache is sending back this strange mime type of "httpd/unix-directory"

该文件的内容是来自后端/alphauser 的正确 html（这是 JSP 的 url 模式），因此返回的有效负载是正确的。好像 apache 正在发回这种奇怪的 mime 类型的“httpd/unix-directory”

Help!

帮助！

It turns out the problem had nothing to do with mod_rewrite. My backend was not sending a ContentType header at all. Once I set it to populate the ContentType as text/htmleverything worked.

事实证明，问题与 mod_rewrite 无关。我的后端根本没有发送 ContentType 标头。一旦我将其设置为在text/html一切正常时填充 ContentType 。

Robert,

罗伯特，

this seems to be weird to me

这对我来说似乎很奇怪

RewriteEngine on
RewriteRule ^$ http://backend/alphauser [P]

the regular expression you made basically match anything fair enougth but it would not pass the URI to the backend.

您制作的正则表达式基本上匹配任何公平的东西，但它不会将 URI 传递给后端。

RewriteEngine on
RewriteRule ^/alphauser/$ http://backend/alphauser [P]

or

或者

RewriteRule ^/$ http://backend/alphauser [P]

I am not 100 % sure how mod_rewrite behave in a .htaccess file

我不是 100% 确定 mod_rewrite 在 .htaccess 文件中的行为

This would make much sense it my opinion, also you have to make sure you have mod_proxyand mod_proxy_httpenabled or it won't work.

我认为这很有意义，您还必须确保已启用mod_proxy并mod_proxy_http启用，否则它将无法工作。
