koa 项目实战（三）创建测试接口和用户模型

const Router = require('koa-router');
const router = new Router();

// 引入User
const User = require('../../models/User');

/**
 * @route GET api/users/test
 * @desc 测试接口地址
 * @access 接口是公开的
 */
router.get('/test', async ctx => {
  ctx.status = 200;
  ctx.body = { msg: 'users works...' };
});

module.exports = router.routes();

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

// 实例化数据模板
const UserSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true
  },
  password: {
    type: String,
    require: true
  },
  avatar: {
    type: String
  },
  date: {
    type: Date,
    default: Date.now
  }
});

module.exports = User = mongoose.model('users', UserSchema);

const Koa = require('koa');
const Router = require('koa-router');
const mongoose = require('mongoose');

// 实例化koa
const app = new Koa();
const router = new Router();

// 引入users.js
const users = require('./routes/api/users');

// 路由
router.get('/', async (ctx) => {
  ctx.body = { msg: 'Hello Koa Interfaces' };
});

// config
const db = require('./config/keys').mongoURI;

// 连接数据库
mongoose
  .connect(db, { useNewUrlParser: true })
  .then(() => {
    console.log('Mongodb Connected...');
  })
  .catch(err => {
    console.log(err);
  })

// 配置路由地址 localhist:5000/api/users
router.use('/api/users', users);

// 配置路由
app.use(router.routes()).use(router.allowedMethods());

// 设置端口号
const port = process.env.PORT || 5000;

// 监听端口号
app.listen(port, () => {
  console.log(`server started on ${port}`)
})
