将常量文件加载到应用程序-Golang

Question

i have a constants file in my main pkg:

package main

const (
  FIRST_NAME                    = "FIRST_NAME"
  LAST_NAME                     = "LAST_NAME"
)

and i'd like to be able to say something like first_name := constants.FIRSTNAME

any idea on how to tell my application "hey, load my constants file and let me access it with constants."?

Answer 1

You can make it a separate package called "constants" if you really want them to be constants.

Or, since your constants aren't really constants (you're using var, not const), you could make a constants struct with the values you want.

type Constants struct {
    FirstName string
    LastName string
}
