How to unmarshal an escaped JSON string

by

You might want to use strconv.Unquote on your JSON string first 🙂

Here’s an example, kindly provided by @gregghz:

package main

import (
    "encoding/json"
    "fmt"
    "strconv"
)

type Msg struct {
    Channel string
    Name string
    Msg string
}

func main() {
    var msg Msg
    var val []byte = []byte(`"{\"channel\":\"buu\",\"name\":\"john\", \"msg\":\"doe\"}"`)

    s, _ := strconv.Unquote(string(val))

    err := json.Unmarshal([]byte(s), &msg)

    fmt.Println(s)
    fmt.Println(err)
    fmt.Println(msg.Channel, msg.Name, msg.Msg)
}
