javascript - HackHands Satellizer 示例 - 意外的 token 问题

Question

我正在使用这个 HackHands 示例来开始使用 Satellizer 并坚持运行 Express 服务器 - https://hackhands.com/building-instagram-clone-angularjs-satellizer-nodejs-mongodb/

这是我的 Server.js-

var bcrypt = require('bcryptjs');
var bodyParser = require('body-parser');
var cors = require('cors');
var express = require('express');
var jwt = require('jwt-simple');
var moment = require('moment');
var mongoose = require('mongoose');
var path = require('path');
var request = require('request');

var config = require('./config');

var User = mongoose.model('User', new mongoose.Schema({

   instagramId: { type: String, index: true },
   email: { type: String, unique: true, lowercase: true },
   password: { type: String, select: false },
   username: String,
   fullname: String,
   picture: String,
  accesstoken: String
 }));
mongoose.connect(config.db);

var app = express();

app.set('port', process.env.PORT || 3000);
app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));

function createToken(user){
  var payload = {
   exp: moment().add(14, 'days').unix(),
    iat: moment().unix(),
    sub: user._id
  };
  return jwt.encode(payload, config.tokenSecret);
}


function isAuthenticated(req, res, next) {
  if (!(req.headers && req.headers.authorization)) {
return res.status(400).send({ message: 'You did not provide a JSON Web Token in the Authorization header.' });
  }

  var header = req.headers.authorization.split(' ');
  var token = header[1];
  var payload = jwt.decode(token, config.tokenSecret);
  var now = moment().unix();

  if (now > payload.exp) {
    return res.status(401).send({ message: 'Token has expired.' });
  }

  User.findById(payload.sub, function(err, user) {
    if (!user) {
      return res.status(400).send({ message: 'User no longer exists.' });
    }

   req.user = user;
    next();
  })
}


app.post('/auth/login', function(req, res) {

  user = user.toObject();
  delete user.password;

  var token = createToken(user);
  res.send({ token: token, user: user });

}

var user = new User({
  email: req.body.email,
  password: req.body.password
});

bcrypt.genSalt(10, function(err, salt) {
  bcrypt.hash(user.password, salt, function(err, hash) {
    user.password = hash;

    user.save(function() {
      var token = createToken(user);
      res.send({ token: token, user: user });
    });
  });
});
  });
});

      res.send({ token: token, user: user });

     app.get('/api/feed', isAuthenticated, function(req, res) {

这是我运行 npm start cmd 时的错误日志-

我总是在终端上收到此错误 -语法错误:意外的标记； 在 Exports.runInThisContext (vm.js:73:16) 在 Module._compile (module.js:443:25) 在 Object.Module._extensions..js (module.js:478:10) 在 Module.load (module.js:355:32) 在 Function.Module._load (module.js:310:12) 在 Function.Module.runMain (module.js:501:10) 启动时(node.js:129:16) 在node.js:814:3

不确定我在这里缺少什么。有人可以帮忙吗？

我的package.json粘贴在下面-

{

“名称”:“instagram 服务器”， “版本”:“0.0.0”， “脚本”:{ “开始”:“Node 服务器.js” }, “依赖项”:{ "bcryptjs": "^2.0.2", "body-parser": "^1.8.1", “cors”:“^2.4.2”， " express ": "^4.9.0", "jwt-simple": "^0.2.0", "时刻": "^2.8.3", " Mongoose ": "^3.8.17", “请求”:“^2.44.0” }

}

Answer 1

我在按照本教程运行 Express 服务器时遇到了同样的问题。我所做的只是删除了 &

改变

if (!(req.headers &&req.headers.authorization))

至

if (!(req.headers && req.headers.authorization))

您还需要为所有包含 & 的后续函数更改它。
