Golang : Read file and convert content to string



Tags : golang read-file ioutil

Problem :

You want to read a file content and convert the content into string.

Solution :

Read the file with ioutil.ReadFile() function. The file content will be in []byte and you just convert the byte into string

 s := string(filecontent)

Below is a full example :

 package main

 import (
  "fmt"
  "io/ioutil"
 )

 func main() {

  file, err := ioutil.ReadFile("testfile.txt")

  if err != nil {
 fmt.Println(err)
 return
  }


  // out the file content
  fmt.Println(string(file))

 }
