How to convert utf8 string to []byte?

Question

I want to unmarshal a string that contains JSON, however the Unmarshal function takes a []byte as input.

How can I convert my UTF8

Answer 1

just use []byte(s) on the string. for example:

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    s := `{"test":"ok"}`
    var data map[string]interface{}
    if err := json.Unmarshal([]byte(s), &data); err != nil {
        panic(err)
    }
    fmt.Printf("json data: %v", data)
}
