Golang : Read file and convert content to string
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))
}
