Make it easy to read arbitrary JSON in Go

gjson

gjson provides a convenient way to read arbitrary JSON in Go.

Install

go get -u github.com/winterssy/gjson

Usage

import "github.com/winterssy/gjson"

Quick Start

• Parse to gjson.Object

data, err := ioutil.ReadFile("./testdata/music.json")
if err != nil {
    log.Fatal(err)
}

obj, err := gjson.Parse(data)
if err != nil {
    panic(err)
}

fmt.Println(obj.GetNumber("code"))
fmt.Println(obj.GetString("data", "total"))
fmt.Println(obj.GetArray("data", "list").Index(0).ToObject().GetString("name"))
// Output:
// 200
// 1917
// 告白气球

• Bind to struct

const dummyData = `
{
  "code": 200,
  "data": {
    "list": [
      {
        "artist": "周杰伦",
        "album": "周杰伦的床边故事",
        "name": "告白气球"
      },
      {
        "artist": "周杰伦",
        "album": "说好不哭 (with 五月天阿信)",
        "name": "说好不哭 (with 五月天阿信)"
      }
    ]
  }
}
`
var s struct {
    Code int `json:"code"`
    Data struct {
        List gjson.Array `json:"list"`
    } `json:"data"`
}
err := gjson.UnmarshalFromString(dummyData, &s)
if err != nil {
    panic(err)
}

fmt.Println(s.Data.List.Index(0).ToObject().GetString("name"))
// Output:
// 告白气球

Build with jsoniter

gjson uses encoding/json as default json package but you can change to jsoniter by build from other tags.

go build -tags=jsoniter .
