Mod rewrite 在nginx中为位置重写设置重写规则

我完全是nginx的不速之客。我正在尝试在nginx中为位置重写设置一些规则。我试图实现的是：

1. no change
https://hello.domain.com/index.php --> https://hello.domain.com/index.php

2. subdomain needs to be included
https://hello.domain.com --> https://hello.domain.com/index.php?sub=hello

3. subdomain & folder structure needs to be included
https://hello.domain.com/dir1/15 --> https://hello.domain.com/index.php?sub=hello&path=dir1/15

4. requests to certain directories ( images, css, etc... ) need to be ignored
https://hello.domain.com/images/logo.png --> https://hello.domain.com/images/logo.png

我可以用这个函数将子域转换成变量$sub

server_name ~^(?<sub>.+)\.domain\.com$;

任何帮助都将不胜感激

这可能有助于您前进：

server_name ~^(?<sub>.+)\.domain\.com$;

location /images {
    # You can put this code in a snippet file and than include
    # it with e.g. `include assets.conf;` so you can use more
    # folders with longest prefix match blocks, which are more
    # efficient than regex blocks.

    # Tell the browser to cache this for one day
    expires 1d;

    # Just give the resource
    try_files $uri =404;
}

location /index.php {
    # PHP stuff goes here
}

location / {
    rewrite ^ /index.php?sub=$sub&path=$uri last;
}

server\u name~ ^（？.+）\.domain\.com$；
位置/图像{
#您可以将此代码放在代码段文件中，然后将其包括在内
#它使用例如“include assets.conf；”这样您就可以使用更多
#具有最长前缀匹配块的文件夹，其中
#比正则表达式块更有效。
#告诉浏览器将此缓存一天
过期1d；
#只需提供资源
try_files$uri=404；
}
location/index.php{
#PHP的东西在这里
}
地点/{
重写^/index.php？sub=$sub&path=$urilast；
}

您可以使用

try_files

来处理案例4，请参阅以获取指导。或者可能是这样：

如果（$request_uri！~“^/（？：images | css）”{rewrite^”/index.php？path=$request_uri&sub=$sub“last；}

我一直在读到，如果不建议使用

条件，这也适用于
位置
范围，因为做了一个内部重定向
server_name ~^(?<sub>.+)\.domain\.com$;

location /images {
    # You can put this code in a snippet file and than include
    # it with e.g. `include assets.conf;` so you can use more
    # folders with longest prefix match blocks, which are more
    # efficient than regex blocks.

    # Tell the browser to cache this for one day
    expires 1d;

    # Just give the resource
    try_files $uri =404;
}

location /index.php {
    # PHP stuff goes here
}

location / {
    rewrite ^ /index.php?sub=$sub&path=$uri last;
}
