调用所有路由功能，直到调用实际路由并调用不存在的路由

标签： node.js express routing

在我的快递申请中，我已经定义了一系列路线如下：

import express from 'express';
import passport from 'passport';
import authStrategies from './auth.strategies';
import authController from './auth.controller';
import authService from './auth.service';

let router = express.Router();


router.post('/', authController.create);
router.get('/login', authController.redirectToLogin);
router.post('/login', authController.loginLocal);
router.get('/', authService.verifyOrdinaryUser, authService.verifyAdmin, authController.index);
router.delete('/:id', authService.verifyOrdinaryUser, authService.verifyAdmin, authController.destroy);
router.get('/me', authService.verifyOrdinaryUser, authController.me);
router.put('/:id/password', authService.verifyOrdinaryUser, authController.changePassword);
router.get('/:id', authService.verifyOrdinaryUser, authController.show);
router.get('/google',
    passport.authenticate('google', {
        scope: ['profile']
    }));
router.get('/google/callback',
    passport.authenticate('google'), authController.googleCallback);
module.exports = router;

我将此路由器添加到server.js中的应用程序：

'use strict'
// import the required modules
import express from 'express';
import passport from 'passport';
import config from './config/config';
import logger from 'morgan';
import cookieParser from 'cookie-parser';
import bodyParser from 'body-parser';
import mongoose from 'mongoose';
import path from 'path';
import auth from './auth/index'

// connect to db
mongoose.connect(config.db.url, {
    useMongoClient : true
});

// initialize the required variables
let db = mongoose.connection,
    app = express();

// log db connection status
db.on('error', console.error.bind(console,'connection error.'));
db.once('open',() => {
    console.log('Successfully connected to server');
});

//set application variables
app.set("port",config.server.port);

// add middleswares
passport.serializeUser(function(user, done) {
    console.log('serialize ',user);
  done(null, user._id);
});

passport.deserializeUser(function(id, done) {
    console.log('deserialize ',id);
  done(null, id);
});
app.use(passport.initialize());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname,'client')));

//add routes
app.use('/auth', auth.router);
app.use('/', (req, res, next) => {
    res.status(200).json({message : "success"});
})

module.exports = app;

现在，当我向/ auth / google发送GET请求时，它会转到路径中的所有路由，这是我的摩根日志：

但对于所有其他路线，它运作正常。

POST /auth/ 200 159.107 ms - 1292
GET /auth/me 200 10.090 ms - 129
GET /auth/5991385d081fb00b1b106422 200 4.367 ms - 52
POST /auth/5991385d081fb00b1b106422/password 200 2.339 ms - 21

如果我将/ google路由作为第一个放在路由器文件中，那么它正常工作。我坚持要解决这个问题。

同样，我们可以看到没有名为/ auth / logme的路由，但是当我尝试访问该路由而不是返回404时，它会抛出以下错误。我在这几个小时，但我无法弄清楚原因。

1 个答案:

答案 0 :(得分：0)

让我们逐一解决问题。 Express路由器是一个正则表达式，并按路由器顺序匹配url。所以路由器的顺序非常重要。

locations.append(Location(title: "A Location", latitude: 0.0, longitude: 0.0, phone: <#Double#>)) 匹配SO。 /auth/logme也匹配router.get('/:id')

您应该首先更改路由器的顺序，如下所示。

/auth/google

这样router.get('/:id')现在匹配router.get('/google/callback', passport.authenticate('google'), authController.googleCallback); router.get('/me', authService.verifyOrdinaryUser, authController.me); router.get('/google', passport.authenticate('google', { scope: ['profile'] })); router.get('/login', authController.redirectToLogin); router.get('/:id', authService.verifyOrdinaryUser, authController.show); router.get('/', authService.verifyOrdinaryUser, authService.verifyAdmin, authController.index); router.post('/login', authController.loginLocal); router.post('/', authController.create); router.delete('/:id', authService.verifyOrdinaryUser, authService.verifyAdmin, authController.destroy); router.put('/:id/password', authService.verifyOrdinaryUser, authController.changePassword); 相关问题：Order of router precedence in express.js

如果你想要404 / / auth / logme 

/auth/google
