Example of Unmarshal (from JSON to struct) in Go

unmarshall_example.go

package main

import (
    "fmt"
    "encoding/json"
    )

type Message struct {
    Name string
    Body string
    Time int64
}

func main() {
    json_test := []byte(`{"Name":"Alice","Body":"Hello","Time":1294706395881547000,"Test":"Test Value"}`)
    var m Message
    err := json.Unmarshal(json_test, &m)
    
    if err != nil {
        panic(err)
    }
    
    fmt.Print(m)
}

"Test" field is not included in Message struct, because in my example I wanted to show that it's possible to partially unmarshal a JSON string.

Can also use:

type Message struct {
    Name string `json: "name"`
    Body string `json: "body"`
    Time int64 `json: "boogabooga"`
}

to unmarshal a json packet with more freeform key names:

{"name":"Alice","Body":"hello","boogabooga":1294706395881547000,"Test":"Test Value"}
