如果 URL 请求路径与某些模式匹配，我会尝试重写/重定向到特定子域。
如果我收到类似这样的请求，我想做这样的事情“https://example.com/users/john/likes“我想以此作为”https://john.example.com/likes“
以下是迄今为止尝试过的方法：我可以创建如下位置
`location ~ ^/users { #TODO: some magic }`
尝试了很多方法使用正则表达式来捕获 uri 的“john”部分，但是没有成功，正则表达式中的很新，有什么想法可以实现它吗？
更新：正如答案中指出的那样，我需要满足来自 nginx conf 的请求，这是我正在使用的配置，请注意，我在子域下测试它：
server {
listen 80;
server_name staging.example.com;
return 301 https://staging.example.com$request_uri;
}
map $name $uri_prefix {
~(.+)$ /users/$1;
}
# This is the new server block I created which will serve the subdomain requests I think i can write conditions in one server block

listen 443 ssl;

答案1
如果您想要接收具有此类 URI 的 HTTP 重定向，请尝试以下操作：
server {
...
server_name www.example.com example.com;
...
location ~ ^/users/([^/]+)(.*)$ {
return 301 $scheme://$1.example.com$2;
}
...
}
但是你的问题不清楚，你是否也需要用 nginx 配置来为这些子域名提供服务？这可以通过一个额外的server块来完成：
map $name $uri_prefix {
~(.+)$ /users/$1;
}
server {
...
server_name ~^(?<name>[^\.]+)\.example\.com$;
...
rewrite ^(.*)$ $uri_prefix$1; # do an internal URI rewriting not visible to the end user
...
# process a rewrited request (now in the form "/users/username/...")
}
不要尝试将这两个server块合并为一个，否则您将收到无限循环。
答案2
您可以尝试以下 nginx 规则：
if ($request_uri ~* "^/users/(.*)/(.*)"){
return 301 hhttps://$1.example.com/$2;
}
