例子1：把字符串转换成结构体：{“FromUid”:”100”,”FromName”:”HANASHAN”}

package main
import (
    "fmt"
    "encoding/json"
)
//接收普通消息结构体
type receiveMessage struct{
    FromUid string        //发送者uid
    FromName string    //发送者名字
}
func main(){
    str := []byte(`{"FromUid":"100","FromName":"HANASHAN"}`)
    var revMsg receiveMessage
    err := json.Unmarshal([]byte(str),&revMsg)
    fmt.Println(err)
    fmt.Println(revMsg)
}

例子2把 [{“Id2”:100,”Title”:”木华黎”},{“Id”:200,”Title”:”耶律楚才”},{“Id”:300,”Title”:”纳呀啊”,”Test”:100}]转换成go的切片

package main
import (
    "encoding/json"
    "fmt"
    "reflect"
)
//接收普通消息结构体
type articles struct{
    Id int         //文章id
    Title string //文章标题
}
func main(){
    //json字符串数组,转换成切片
    articleStrings := `[{"Id2":100,"Title":"木华黎"},{"Id":200,"Title":"耶律楚才"},{"Id":300,"Title":"纳呀啊","Test":100}]`
    var articleSlide []map[string]interface{}
    multiErr := json.Unmarshal([]byte(articleStrings),&articleSlide)
    if multiErr!=nil{
        fmt.Println("转换出错：",multiErr)
    }
    for k,v:=range articleSlide{
        fmt.Println("第",k,"个数的值是:",v,v["Id"],v["Title"])
    }
    fmt.Println(reflect.TypeOf(articleSlide))
}
