在Nginx中使用正则表达式重定向子域

nginx文档说 server_name指令支持正则表达式.我一直把头撞在墙上，试图使琐碎的正则表达式正常工作.

The nginx documentation says that the server_name directive supports regular expressions. I've been banging my head against the wall trying to get even a trivial regex working.

我希望 subdomain.mydomain 重定向到 mydomain/subdomain

这是我的代码.

server { server_name "~^subdomain\.mydomain\$"; rewrite ^ mydomain/subdomain; }

此外，可能值得注意.在nginx的配置文件中，还有一个规则:

Also, potentially noteworthy. Further down in the nginx config file there is a rule:

server { server_name *.mydomain ... }

我在做什么错了?

更新:

已建议我不要为此使用正则表达式...以便提供更多的清晰度:琐碎的正则表达式只是出于故障排除的目的.真正的正则表达式看起来更像是...

It has been suggested that I not use regex for this... to offer a little more clarity: the trivial regex was simply for purposes of troubleshooting. The real regex will look more like...

server { server_name "~^.*(cvg|cincinnati)\.fakeairport(app)?\.(org|com)$"; rewrite ^ fakeairport/cincinnati; } server { server_name "~^.*(lex|lexington)\.fakeairport(app)?\.(org|com)$"; rewrite ^ fakeairport/lexington; }

因此，最好使用正则表达式.

So it would be preferable to use regex.

使用nginx 1.1.19，您可以执行以下操作:

using nginx 1.1.19 you can do the following:

server { server_name ~^(?<subdomain>\w+)\.domainA\$; location / { rewrite ^ $subdomain.domainB$request_uri permanent; } }

domainA之前的子域被匹配并存储在变量$ subdomain中，然后可以在重写中使用它. 这仅用一个服务器指令将xxx.domainA之类的网址重写为xxx.domainB.

The subdomain before domainA is matched and stored in variable $subdomain which then can be used in the rewrite. This rewrites url like xxx.domainA to xxx.domainB with only one server directive.
