JSON

Parsing data from a response

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

Parsing Into Struct

type App struct {
    Id string `json:"id"`
    Title string `json:"title"`
}

data := []byte(`
    {
        "id": "k34rAT4",
        "title": "My Awesome App"
    }
`)

var app App
err := json.Unmarshal(data, &app)

Struct => Json

b, err := json.Marshal(m)

Simpler Parsing Into Struct

will need to be same as JSON keys and vals(not case sensitive)

type Tour struct {
    Name, Price string 
}

Printing Byte Array

fmt.print("%s", byt)

Decoder

Grab json data from content using you struct

func toursFromJson(content string) []Tour { //content is array of JSON
    tours := make([]Tour, 0, 20)

    decoder := json.NewDecoder(string.NewReader(content))
    _, err := decoder.Token() //throw away that first '[' 
    checkError(err)

    var tour Tour
    for decoder.More() { //More asks if there is another data entity and if true returns true and moves decoder there
        err := decoder.Decoder(&tour)//parse JSON and only get those values in your struct leaving it in tour
        checkError(err)
        tours = append(tours, tour)
    }

    return tours
}
