如何使用MongoDB + NodeJS Express向ReactJS React Router和Redux添加登录验证和会话？

Question

我有一个MongoDB + NodeJS Express服务器,运行Webpack并能够向用户注册数据库的凭据.我现在想在用户登录时添加身份验证和会话.我正在调查Passport.js但似乎无法掌握如何将所有内容放在一起.

最好的方法是什么？任何例子和指导将不胜感激.

到目前为止,这些是我的设置.

对于服务器:

var express = require('express');
var path = require('path');
var config = require('../webpack.config.js');
var webpack = require('webpack');
var webpackDevMiddleware = require('webpack-dev-middleware');
var webpackHotMiddleware = require('webpack-hot-middleware');
var bodyParser = require('body-parser');
var MongoClient = require('mongodb').MongoClient;
var ObjectId = require('mongodb').ObjectID;

var app = express();
var db;

var compiler = webpack(config);

app.use(webpackDevMiddleware(compiler, {noInfo: true, publicPath: config.output.publicPath}));

app.use(webpackHotMiddleware(compiler));

app.use(express.static('dist'));

app.use(bodyParser.json());

app.post('/api/users/', function(req, res) {
  console.log('Req body', req.body);
  var newUser = req.body;
  db.collection('users').insertOne(newUser, function(err, result) {
    if(err) console.log(err);
    var newId = result.insertedId;

    db.collection('users').find({_id: newId}).next(function(err, doc) {
      if(err) console.log(err);
      res.json(doc);
    })
  })
})

app.get('/', function (req, res) {
  res.sendFile(path.resolve('client/index.html'));
});

MongoClient.connect('mongodb://localhost/testdb', function(err, dbConnection) {
  if(err) console.log(err);

  db = dbConnection;
  var server = app.listen(3000, function() {
      var port = server.address().port;
      console.log("Started server at port", port);
  });
});

至于路由器(正在登录页面Login和正在呈现的注册页面Register):

//react-router
render(
  <div>
    <Provider store={store}>
      <Router history={hashHistory}>
        <Route
          component ={MainPage}
          path='/'
        >
          <IndexRoute component={Login}/>
          <Route
            component={Register} path="Register"
          />
        </Route>
      </Router>
    </Provider>
  </div>,
  document.getElementById('app')
)

redux中的API POST请求:

//How registered user's credentials are stored via action in redux
  registerUser(username, email, name, password) {
    console.log('Started registering request')
    var user = {
      username: username,
      email: email,
      name: name,
      password: password,
    }

    var request = {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(user)
    }

    console.log('Adding user: ', user)

    fetch(`http://localhost:3000/api/users`, request)
    .then(res => res.json())
    .then(user => {
      console.log(user);
      return user;
    })
    .catch(err => {
      console.log('Error is', err)
    })

    console.log('Ending registering request')
  },

如果我很清楚您需要保持用户登录状态。我建议您在用户登录jwt后使用 jwt 创建令牌并将此令牌存储到 localstorage.setItem(token) 中。

希望有帮助
