//下载 插件 npm install egg-jwt --save // {app_root}/config/plugin.js 配置插件 exports.jwt = { enable: true, package: "egg-jwt" }; // {app_root}/config/config.default.js 设置密钥 exports.jwt = { secret: "123456" //自己设置的值 };
自己画的流程图：
react/src/views/login.jsx:
post('/login',{username,psw}).then(res => { console.log(res) // 后端返回的token window.localStorage.setItem('token',res) })
egg / app / controller / login.js:
'use strict'; const Controller = require('egg').Controller; class LoginController extends Controller { async index() { const { ctx } = this; let {userName,psw} = ctx.request.body; let result = await this.service.login.index(userName,psw) // 交给service处理生成 token ctx.body = result; } } module.exports = LoginController;
egg / app / service/ login.js:
module.exports = app => { class LoginService extends app.Service { async index(userName,psw) { if(userName&&psw){ const token = app.jwt.sign({ userName,psw }, app.config.jwt.secret,{expiresIn:'24h'}); /* * sign({根据什么生成token}) * app.config.jwt.secret 配置的密钥 * {expiresIn:'24h'} 过期时间 */ return token } } } return LoginService }
egg / app/ router.js:
router.get('/getData',jwt, controller.getData.index); // jwt 指明这个请求需要token才能收到返回结果
拦截器：
//拦截 request.interceptors.request.use((config) => { config.headers.authorization = `Bearer ${window.localStorage.getItem("token")}`; return config; }, (err) => { console.error(err); }); //拦截响应 request.interceptors.response.use((response) => { return response.data; }, (err) => { console.log(err); });
