Golang转换JSON

Question

我正在研究Golang，GORM以使用Echo Framework实现API

我正在使用以下结构和函数来生成JSON

type User struct {
    gorm.Model
    Name     string `json:"name"`
    Username string `json:"username"`
    Password string 
}

func GetUsers(c echo.Context) error {
    db := db.GetDBInstance()
    users := []model.User{}
    db.Find(&users)
    return c.JSON(http.StatusOK, users)
}

这是我的JSON响应

[
 {
  ID: 1,
  CreatedAt: "2020-04-21T05:28:53.34966Z",
  UpdatedAt: "0001-01-01T00:00:00Z",
  DeletedAt: null,
  name: "",
  username: "test",
  Password: "test123"
 }
]

我想将其转换为以下JSON

{
  data: [{
   ID: 1,
   CreatedAt: "2020-04-21T05:28:53.34966Z",
   UpdatedAt: "0001-01-01T00:00:00Z",
   DeletedAt: null,
   name: "",
   username: "test",
   Password: "test123"
  }]
}

任何帮助将不胜感激

type Data struct{
    Data []model.User `json:"data"`
}

func GetUsers(c echo.Context) error {
    db := db.GetDBInstance()
    users := []model.User{}
    db.Find(&users)
    data := &Data{
        Data: users,
    }
    return c.JSON(http.StatusOK, data)
}
