某些路线转到404错误页面快递 [英] Certain routes go to 404 error page express

问题描述

我正在设置我的第一个节点项目.在开始移动某些内容之前，我所有的页面都运行良好.我已经为 index.js 中的不同页面完成了所有路由.我已经进行了更改，并在我的rotes文件夹中创建了一个 login.js 文件，以分解一些逻辑.以前，所有网址都可以正常工作并正确显示页面.重构后，对于所有登录路径，我一直收到404页面未找到的错误.

I am setting up my first node project. I had all the pages working nicely until I started to move some thing around. I have done all of my routing for different pages in index.js. I have changed that and created a login.js file within my rotes folder to break up some of the logic. Before, all urls were working and displaying pages correctly. Post refactoring, I keep getting 404 page not found errors for all of the login routes.

app.js:

var express = require('express');
var exphbs  = require('express-handlebars');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var passport = require('passport');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
var login = require('./routes/login');
//Using firebase initialized in config file.
var database = require('./config/firebase');
var app = express();


///Setting stuff up here .....

app.use('/', routes);
app.use('/login', login);

app.use(function(req,res){
    res.status(404);
    res.render('404');
});

module.exports = app;

index.js:

var express = require('express');
var router = express.Router();
var csrf = require('csurf');
var csrfProtection = csrf();
var firebase = require('firebase');
var login = require('./login'); 


//tell express: All routes should be protected by csrf protection.
router.use(csrfProtection);

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('home', { title: 'Express' });
});

module.exports = router;

login.js:

var express = require('express');
var router = express.Router();
var csrf = require('csurf');
var csrfProtection = csrf();
//Using firebase initialized in config file.
var database = require('../config/firebase');

router.use(csrfProtection);

router.get('/login', function(req, res, next) {
  res.render('login', { title: 'Login' });
});

router.get('/forgotpassword', function (req,res){
    res.render('forgotpassword', {title:'Forgot Password'})
});

//ADD A TERMS PAGE TO SHOW TERMS AND CONDITIONS
router.get('/signup', function (req,res){
    res.render('signup', {title:'Sign up', csrfToken: req.csrfToken()});
});

router.post('/signup', function(req, res, next){
    res.redirect('/');
});

module.exports = router;

index.js 正在正确呈现主视图.其余的路由，例如/login或/signup都将转到404，我似乎无法弄清楚为什么.

The index.js is rendering the home view properly. Rest of the routes, like /login, or /signup are all going to 404 and I can't seem to figure out why.

推荐答案

执行此操作时:

app.use('/login', login);

您要告诉Express，所有以/login 开头的请求都应传递到登录"路由器.

You're telling Express that all requests starting with /login should be passed to the "login" router.

在该路由器中，您要处理的任何URL均应相对于该/login 前缀(这也是有点解释，

In that router, any URL's that you want to handle should be relative to that /login prefix (this is also somewhat explained here).

换句话说，如果要为/login 本身添加处理程序，则需要添加以下内容:

In other words, if you want to add a handler for /login itself, you need to add this:

router.get('/', function(req, res, next) { ... });

这也会给您带来一个问题，因为如果我对您的理解正确，那么您还需要一个用于/signup 的处理程序，您无法从已经以为前缀的路由器中创建该处理程序/login .就您而言，您的路由器正在为/login/signup 创建一个处理程序.

This will also present an issue for you, because if I understand you correctly, you also want a handler for /signup, which you cannot create from a router that is already prefixed with /login. In your case, your router is creating a handler for /login/signup.

您将需要一个单独的路由器来处理/signup ，并将其附加到主应用中，如下所示:

You're going to need a separate router to handle /signup, and attach it to the main app like this:

app.use('/signup', signup);
