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)

OpenSSL, as an open source library widely used in secure communications, provides encryption algorithms, keys and certificate management functions. However, there are some known security vulnerabilities in its historical version, some of which are extremely harmful. This article will focus on common vulnerabilities and response measures for OpenSSL in Debian systems. DebianOpenSSL known vulnerabilities: OpenSSL has experienced several serious vulnerabilities, such as: Heart Bleeding Vulnerability (CVE-2014-0160): This vulnerability affects OpenSSL 1.0.1 to 1.0.1f and 1.0.2 to 1.0.2 beta versions. An attacker can use this vulnerability to unauthorized read sensitive information on the server, including encryption keys, etc.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
