How do I convert [Size]byte to string in Go?

问题:

I have a sized byte array that I got after doing md5.Sum().

data := []byte("testing") var pass string  var b [16]byte b = md5.Sum(data) pass = string(b) 

I get the error:

cannot convert b (type [16]byte) to type string

回答1:

You can refer to it as a slice:

pass = string(b[:])

A little late but keep in mind that using string(b[:]) will print mostly invalid characters.

If you're trying to get a hex representation of it like php you can use something like:

data := []byte("testing") b := md5.Sum(data)  //this is mostly invalid characters fmt.Println(string(b[:]))  pass := hex.EncodeToString(b[:]) fmt.Println(pass) // or pass = fmt.Sprintf("%x", b) fmt.Println(pass)

Make a slice of it:

pass = string(b[:]) 

回答4:

it can be solved by this

pass = fmt.Sprintf("%x", b) 

or

import "encoding/base64" pass = base64.StdEncoding.EncodeToString(b[:]) 

this will encoding it to base64 string
