插件配置

 config.session = { 
    encrypt: false, signed: false, // maxAge: 10000 } config.redis = { 
    client: { 
    port: 6379, // Redis port host: '127.0.0.1', // Redis host password: 'auth', db: 0, } } config.mongoose = { 
    url: 'mongodb://127.0.0.1/redis-mongoose', options: { 
   }, // mongoose global plugins, expected a function or an array of function and options } 

/ @type Egg.EggPlugin */ module.exports = { 
    // had enabled by egg // static: { 
    // enable: true, // } nunjucks: { 
    enable: true, package: 'egg-view-nunjucks', }, redis: { 
    enable: true, package: 'egg-redis', }, session: true, mongoose: { 
    enable: true, package: 'egg-mongoose', } }; 

路由

module.exports = app => { 
    const { 
    router, controller } = app; router.get('/', controller.home.index); router.get('/sign', controller.login.signHtml); router.post('/api/sign', controller.login.sign); router.get('/login', controller.login.loginHtml); router.post('/api/login', controller.login.login); router.get('/logout', controller.login.logout); }; 

控制器

//app/controller/home.js 'use strict'; const Controller = require('egg').Controller; class HomeController extends Controller { 
    async index() { 
    const { 
    ctx } = this; if (ctx.session.login) { 
    await ctx.render('home'); } else { 
    ctx.redirect('/login'); } } } module.exports = HomeController; 

// app/controller/login.js 'use strict'; const Controller = require('egg').Controller; class SignController extends Controller { 
    async signHtml() { 
    const { 
    ctx, app } = this; // console.log(user); await ctx.render('sign'); } async sign() { 
    const { 
    ctx, app } = this; // console.log('================',ctx.request.body); const requestBody = ctx.request.body; await ctx.model.User.insertMany({ 
    username: requestBody.username, password: requestBody.password }); // console.log(user); ctx.body = '<h1>注册成功！</h1>'; } async loginHtml() { 
    const { 
    ctx, app } = this; await ctx.render('login'); } async login() { 
    const { 
    ctx, app } = this; const requestBody = ctx.request.body; const inputPassword = requestBody.password; const findUser = await ctx.model.User.find({ 
    username: requestBody.username, }); if (findUser.length && findUser[0].password === inputPassword) { 
    ctx.session.login = true; ctx.redirect('/'); } else { 
    ctx.redirect('/login'); } // console.log('findUser', findUser) } async logout() { 
    const { 
    ctx, app } = this; ctx.session.login = false; ctx.redirect('/login'); } } module.exports = SignController; 

model

// {app_root}/app/model/user.js module.exports = app => { const mongoose = app.mongoose; const Schema = mongoose.Schema; const UserSchema = new Schema({ username: { type: String }, password: { type: String }, }); return mongoose.model('User', UserSchema); }
