How to have consistent response format in go-optical
php小编子墨今天为大家介绍如何在 go-optical 中实现一致的响应格式。在开发过程中,我们经常会面临不同的请求和返回数据格式,这给前后端的协作带来了一定的困扰。而 go-optical 是一个强大的工具,它可以帮助我们轻松实现统一的响应格式,提高开发效率。本文将详细介绍 go-optical 的使用方法,帮助读者快速掌握如何在项目中应用这一工具,实现一致的响应格式,提升开发效率和协作效果。让我们一起来看看吧!
问题内容
我在此处的端点内有一个查询,
query := `SELECT * FROM "user" WHERE username = $1` row := db.QueryRow(query, user.Username) var ( usn string pass string created_at string id int ) // binds the above variables to "row" that is returned by "db.QueryRow" // "row.Scan" will also release the connection if err := row.Scan(&usn, &pass, &created_at, &id); err != nil { return c.Status(500).JSON(fiber.Map{ "error": err, }) } return c.JSON(fiber.Map{ "username": usn, "password": pass, "created_at": created_at, "id": id, })
当我到达这个端点时,响应是,
{ "created_at": "timestamp", "id": 3, "password": "123", "username": "bro" }
我该如何做才能使响应就像我返回它的方式一样,
{ "username": "bro", "password": "123", "created_at": "timestamp", "id": 3, }
解决方法
如果你想确保顺序,你可以使用 struct 而不是 map 。 地图不保留顺序键数。
type UserResponse struct { Username string `json:"username"` Password string `json:"password"` CreatedAt string `json:"created_at"` ID int `json:"id"` } .... your code response := UserResponse{ Username: usn, Password: pass, CreatedAt: created_at, ID: id, } return c.JSON(response)
