I'm already in C:\Windows\System32\drivers\etc\hosts.
127.0.0.1 www.test.com

With 127.0.0.1:81 can be accessed using www.test.com directly is "Unable to display this page"
------to solve the idea----------------------
Big Brother, you have to add a port number, okay!
www.test.com:81
If you don't serve something the slogan, change 81 to 80.
------to solve the idea----------------------
The default is 80 port, you change to 81 will add port OH
And www.test.com is not your real domain name, you have to add in the local Hosts file
192.168.1.100www.test.com
192.168.1.100 is the IP of your nginx server.
------to solve the idea----------------------
Use Phpfind directly, there is no need to waste time on the configuration
