如何访问其他包中的变量

Question

How can I move my global variable to other package in Go?

like

package main
import "myapp/controllers"

var something string

func main(){ 
  something = "some text" 
}

Answer 1

Like you want to have a globally accessible variable in your package controllers?:

package controllers

var Something string

func init(){ 
    Something = "some text" 
}

And then you can do

package main
import (
    "myapp/controllers"
    "fmt"
)

func main(){ 
    fmt.Println(controllers.Something) //some text
}
