vue3+threejs+koa可视化项目——实现登录注册（第三步）

⭐前言

大家好，我是yma16，本文分享关于 vue3+threejs+koa可视化项目——实现登录注册。

jwt登录注册
JWT（JSON Web Token）是一种标准的身份验证和授权解决方案，它通过使用JSON格式的令牌来实现用户的身份验证和授权，避免了传统的基于会话的身份验证方案的一些问题。

JWT登录注册的原理如下：

1. 注册：用户在注册时提供用户名和密码，服务器将用户信息保存在数据库中。密码通常需要进行哈希处理，以增加安全性。

2. 登录：用户提供用户名和密码进行身份验证时，服务器验证用户名和密码是否匹配数据库中的记录。如果匹配成功，服务器会为该用户生成一个JWT令牌。

3. 令牌生成：JWT由三部分组成，分别是头部（header）、载荷（payload）和签名（signature）。头部包含算法和令牌类型等信息，载荷包含用户的身份信息和其他自定义信息，签名用于验证令牌的合法性。

4. 令牌签名：服务器使用服务器端的私钥对头部和载荷进行签名，生成签名部分。客户端接收到令牌后，可以使用服务器端的公钥进行验证，确保令牌没有被修改过。

5. 令牌的验证和使用：客户端在每次请求时将令牌作为请求的一部分（通常是在请求头的"Authorization"字段中）发送到服务器。服务器通过解析令牌的签名部分并验证签名的合法性，确定令牌的有效性。如果通过验证，服务器可以根据令牌中的载荷部分进行用户的身份验证和授权等操作。

6. 令牌的刷新：JWT令牌通常有一个过期时间，当令牌过期时，客户端需要重新获取新的令牌。在令牌过期之前，客户端可以使用刷新令牌来获取新的令牌，而无需重新进行身份验证。

通过JWT登录注册的方式，可以实现无状态的身份验证和授权，减少服务器的负担和数据库的访问频率。同时，JWT还可以跨多个服务进行验证和授权，提高了系统的可扩展性和安全性。

⭐总结

前端vue3
a. 路由拦截
b. store缓存token

后端koa
a. jwt配置
b. jwt的白名单（发送验证码、注册、获取token）

Koa JWT is a middleware for Koa.js, a web application framework for Node.js. JWT, short for JSON Web Token, is a compact and self-contained mechanism for securely transmitting information between parties as a JSON object.
Koa JWT provides authentication and authorization functionalities using JWT in Koa applications. It allows you to generate and verify JWT tokens, protect routes from unauthorized access, and retrieve authenticated user information from the JWT token.

Koa JWT 是 Koa.js 的中间件，Koa 是 Node.js 的 Web 应用程序框架。JWT 是 JSON Web 令牌的缩写，是一种紧凑且独立的机制，用于将信息作为 JSON 对象在各方之间安全地传输。
Koa JWT 在 Koa 应用程序中使用 JWT 提供身份验证和授权功能。它允许您生成和验证 JWT 令牌，保护路由免受未经授权的访问，并从 JWT 令牌中检索经过身份验证的用户信息。
