# jsonquery

一个方便的json值获取库, go的json解析方式要么需要预先定义结构，要么需要处理map[string]interface{}。第一种取值方便，解析麻烦。第二种解析时方便，取值时麻烦。而这个库综合了这两种方式的优点。

```go

package main

import (

	"fmt"

	jq "github.com/guidao/jsonquery"

)

func main() {

	//error

	v := jq.NewLens().Key("inner").GetWithJson(`{}`)

	fmt.Println(v.StringOr("default"), v.Error())

	//object

	hello := jq.NewLens().Key("hello").GetWithJson(`{"hello": "world"}`).StringOr("")

	fmt.Println(hello) // world

	//array

	f23, err := jq.NewLens().Key("array").Index(2).GetWithJson(`{"array":["hello", "world", 23]}`).Float64()

	fmt.Println(f23, err) //23, nil

	//foreach

	err = jq.NewLens().Key("array").GetWithJson(`{"array":["hello", "world", 23]}`).ForeachArray(func(i int, v jq.Value) {

		fmt.Printf("i:%v, v:%v\n", i, v.InterfaceOr(nil))

		// i:0, v:hello

		// i:1, v:world

		// i:2, v:23

	})

	fmt.Println(err) //nil

}

```
