Method of getting system environment variables in GO language

This article demonstrates an example of how the GO language gets system environment variables. Share with you for your reference. The specific implementation method is as follows:

package main

import (

 "fmt"

 "os"  // We're going to use os In the package env

)

func main() {

 //os.Getenv Retrieve the environment variable and return the value, which would be empty if the variable did not exist. 

 HOME:= os.Getenv("HOME")

 fmt.Println(HOME)

 fmt.Printf(os.Getenv("JAVA_HOME"))

}

I hope this article has been helpful to your programming of Go language.
