Stop Windows Ask Firewall When Go Run
When working with REST api with golang on Windows. Every time you run your program, Windows Firewall may complaint like that

You can prevent it by replacing listening address with localhost or 127.0.0.1
// change
http.ListenAndServe(":3000", r)
// to
http.ListenAndServe("127.0.0.1:3000", r)
This strict was applied to any frameworks as well, including Fiber, Gin, Iris, and Echo …
Happy coding :)
