nginx vhosts configuration problem

Question

My two domain names are pointed to the server
The first www.xxx.cn
The second api.xxx.cn

I pointed the api to a directory and configured api.xxx.cn.conf so that it can be accessed normally.

Then I visit www.xxx.cn and it also points to the api.xxx.cn directory I configured.

There are only two files in the vhosts directory
One is api.xxx.cn.conf
and the other is localhost.conf

If www.xxx.cn is not configured, it should point to the root directory of the default configuration. Why does it also point to api

api.xxx.cn.conf configuration details

Answer 1

Because your domain name resolves to the same place. You can configure a default IP binding to block it.

Answer 2

You can configure to prohibit empty host access

server {
    server_name _;//标识空主机
    return 500;//返回500错误
}
