	Timestampstring

functestJson(){
	varDataJsonData
	/*time1:=time.Now().Unix()
	x:=Header{FileName:"yangheng",Host:"localhost",Offset:"123",Timestamp:string(time1)}*/
	Data.header="123"
	Data.Body="234"

	fmt.Printf("data%v\n",Data)

	lang,err:=json.Marshal(Data)
	iferr==nil{
		fmt.Printf("result%v\n",string(lang))
	}
}

输出结果

data {123 234}

result {"body":"234"}

总之，要解析成json格式，struct里面变量必须大写
