app.use不要被解雇

Question

我正在尝试在应用程序中使用中间件来检查所有路由是否都通过了令牌，此刻我只想使用/ users路由对其进行测试，因此我在我的应用程序文件中进行了此操作：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var debug = require('debug')('express-sequelize');
var http = require('http');
var models = require('./models');
var jwt = require('./routes/jwt');
var app = express();


// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/',require('./routes/authentication'));

app.use('/users',jwt); // executa a verificacao do token em todas as rotas excepto o registo e login


// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

然后在我的jwt文件中，我这样做：

var express = require('express');
var User = require('../models').User;
var router = express.Router();
var jwt = require('jsonwebtoken');

// route middleware to verify a token
module.exports = function () {
    return function (req, res, next) {
        console.log("entered");
        // check header or url parameters or post parameters for token
        var token = req.body.token || req.query.token || req.headers['x-access-token'];
        // decode token
        if (token) {
            // verifies secret and checks exp
            jwt.verify(token, app.get('superSecret'), function (err, decoded) {
                if (err) {
                    return res.json({ success: false, message: 'Failed to authenticate token.' });
                } else {
                    // if everything is good, save to request for use in other routes
                    req.decoded = decoded;
                    next();
                }
            });
        } else {
            // if there is no token
            // return an error
            return res.status(403).send({
                success: false,
                message: 'No token provided.'
            });

        }
    }
};

我的jwt文件位于路由文件夹中，该文件夹与应用程序文件位于同一级别，有任何建议吗？ 它没有达到路线

您的jwt文件未正确设置，请将其更改为

var express = require('express');
var User = require('../models').User;
var router = express.Router();
var jwt = require('jsonwebtoken');

router.get('/', function(req, res, next) {
    console.log("entered");

    // check header or url parameters or post parameters for token
    var token = req.body.token || req.query.token || req.headers['x-access-token'];
    // decode token
    if (token) {
        // verifies secret and checks exp
        jwt.verify(token, app.get('superSecret'), function (err, decoded) {
            if (err) {
                return res.json({ success: false, message: 'Failed to authenticate token.' });
            } else {
                // if everything is good, save to request for use in other routes
                req.decoded = decoded;
                next();
            }
        });
    } else {
        // if there is no token
        // return an error
        return res.status(403).send({
            success: false,
            message: 'No token provided.'
        });

    }
})

module.exports = router;
