go原生的json解析器：encoding/json 和第三方的json解析器在 Marshal 上基本没有差别，但是在Unmarshal上差别还是很大的，听说go 1.10版本原生 json 和 第三方json解析器：github.com/json-iterator/go 性能持平，已经用不到第三方 json 解析器了。
注：test.json 文件下载（1569308行），（下载之后放在和 main.go 同一个文件夹下）

1、原生：

if err != nil{

func MarshalWithDefault(){
const jsonStream = `

2、第三方：
package common
import (
jsoniter "github.com/json-iterator/go"
"io/ioutil"
)
func HandleJsonWithJsoniter(jsonFile string) {
byteValue, err := ioutil.ReadFile(jsonFile)
if err != nil{
panic(err)
}
var s interface{}
var json = jsoniter.ConfigCompatibleWithStandardLibrary
err = json.Unmarshal([]byte(byteValue),&s)
if err != nil{
panic(err)
}
//fmt.Println(s)
}
func MarshalWithJsoniter(){
const jsonStream = `
{ "Name" : "Ed" , "Text" : "Knock knock." }
{ "Name" : "Sam" , "Text" : "Who's there?" }
{ "Name" : "Ed" , "Text" : "Go fmt." }
{ "Name" : "Sam" , "Text" : "Go fmt who?" }

3、main函数：
package main
import (
common "JsonAnalyse/jsonDemo/Common"
"fmt"
"time"
)
func main() {
//1.golang的原生json解析器：encoding/json：
//t1 := time.Now()
//common.MarshalWithDefault()
//common.HandleJsonWithDefault("test.json")
//elapsed := time.Since(t1)
//fmt.Printf("执行消耗的时间为:%v", elapsed)
//2.第三方json解析器：github.com/json-iterator/go：
t1 := time.Now()
common.HandleJsonWithJsoniter("test.json")
//common.MarshalWithDefault()
elapsed := time.Since(t1)
fmt.Printf("执行消耗的时间为:%v", elapsed)
}
