import (
    "fmt"
    "encoding/json"
)

type Response struct {
    Code int         `json:"code"`
    Msg  string      `json:"msg"`
    Data interface{} `json:"data"`
}
type Product struct {
    Name      string
    ProductID int64
    Number    int
    Price     float64
    IsOnSale  bool
}

func main {

    p := &Product{}
    p.Name = "err"
    p.IsOnSale = true
    p.Number = 10000
    p.Price = 2499.00
    p.ProductID = 1
    datae, _ := json.Marshal(p)
    //fmt.Println(string(datae))   {"Name":"err","ProductID":1,"Number":10000,"Price":2499,"IsOnSale":true}
    data := string(datae)
    response := &Response{
        Code: 1,
        Msg:  "没有找到该用户或者密码错误",
        Data: json.RawMessage(data),
    }
    b, err := json.Marshal(&response)
    if err != nil {
        fmt.Println("err", err)
    }
    //fmt.Println(string(b)) {"code":1,"msg":"没有找到该用户或者密码错误","data":{"Name":"err","ProductID":0,"Number":0,"Price":0,"IsOnSale":false}}
    c.Data["json"] = string(b)
    c.ServeJSON()
    return

}

//打印语句

{"code":1,"msg":"没有找到该用户或者密码错误","data":{"Name":"err","ProductID":0,"Number":0,"Price":0,"IsOnSale":false}}
