Nginx子域try_文件（具有请求_uri）

[现状]

sub.domain.com=>domain.com/users/？user\u name=sub[确定]

我怎么能这样改变

sub.domain.com/？page=about=>domain.com/users/？user\u name&page=about[FAIL]

请帮助..

尝试_文件$uri$uri/users/index.php？user_name=$subdomain&$args；非常感谢DDD

server {
    server_name ~(<subdomain>[^\.]*).domain.com;
    root /var/www;

    location / {
            try_files $uri $uri/users/index.php?user_name=$subdomain&$request_uri;
    }

    location ~ \.php$ {
            ...
    }
}
