Nginx转发解析长域名多路径域名

​Nginx解析短域名，例如：访问 http://192.168.1.23 可直接跳转到 http://192.168.1.23/webroot/decision

server {
    listen 90;
    server_name localhost;
    
    #匹配/ 转到/webroot/decision上；
    #^(.*)$表示/后任意部分，除非和其他location匹配否则一律转向/webroot/decision，如果无需这样可以修改这里location或者rewrite的正则；
    #permanent表示重定向并返回301；
  
    location / {
        rewrite ^(.*)$ /webroot/decision permanent;
    }
    location /webroot {
        proxy_pass http://crm;
        ......
    }
}

实际案例：

server{
      listen 443 ssl;
      server_name ***.***.cn;
          ssl_certificate      ssl/server.crt;
          ssl_certificate_key  ssl/server.key;
          ssl_session_cache    shared:SSL:1m;
          ssl_session_timeout  5m;
          ssl_ciphers  HIGH:!aNULL:!MD5;
          ssl_prefer_server_ciphers  on;
          ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
           location / {
        rewrite ^(.*)$ /webroot/decision permanent;
    }
  location /webroot {
          proxy_set_header HOST $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_pass  http://xxx.xxx.xxx.xxx:8080;
      }
  }
