# Node-koa2-mongodb-demo

> An API template by using koa2 + mongodb + passport + JWT.

## 一、koa setting

The base infrastructure of koa...

```

const Koa = require('koa')

const app = new Koa()

app.listen(3000)

```

详情请参考：[github - koa](https://github.com/koajs/koa)

## 二、mongodb setting

```

const mongoose = require('mongoose')

mongoose.Promise = global.Promise

mongoose.connect(config.mongo.uri, config.mongo.options).then(

  () => { // success! },

  err => { // error }

)

```

详情请参考：[mongoose official](http://mongoosejs.com/)

## 三、passport-auth

```

const passport = require('koa-passport')

const LocalStrategy = require('passport-local')

const JwtStrategy = require('passport-jwt').Strategy

const ExtractJwt = require('passport-jwt').ExtractJwt

const User = require('../schemas/user')

const config = require('../config')

/** 用户名密码验证策略 */

const localOptions = { // or whatever you want to use

  usernameField: 'email',    // define the parameter in req.body that passport can use as username and password

  passwordField: 'password',

  session: false

}

passport.use(new LocalStrategy (localOptions, 

  /**

   * @param username 用户输入的用户名

   * @param password 用户输入的密码

   * @param done 验证验证完成后的回调函数，由passport调用

   */

  (username, password, done) => {

    User.findOne({ email: username }, function(err, user) {

      if (err) { return done(err); }

      if (!user) {

        return done(null, false, { message: 'Incorrect email.' });

      }

      user.validPassword(password, (err, isAuthorize) => {

        if (!isAuthorize) {

          return done(null, false, { message: 'Incorrect password.' });

        }

        return done(null, user);

      })

    });

  }

))

/** JWT验证 */

const jwtOptions = {

  jwtFromRequest : ExtractJwt.fromAuthHeaderWithScheme('bearer'),

  secretOrKey : config.secret,

  session: false

}

passport.use(new JwtStrategy(jwtOptions, async (payload, done) => {

  const user = await User.findById(payload.user.id).exec();

  if(user)

      done(null, user);

  else

      done(null, false);

}))

module.exports = passport;

```
