Router.use需要中间件功能吗？ [英] Router.use requires middleware function?

问题描述

所以我试图在一个名为login_routes.js的单独JS文件中分隔我的登录路线

So I'm trying to seperate my login routes in a seperate JS file called login_routes.js

我一直收到这个特定的错误：

I keep getting this specific error:

TypeError：Router.use（）需要中间件函数，但在Function处获得了一个Object
。 （/Users/ethanthomas/Desktop/mean-stuff/express-server/node_modules/express/lib/router/index.js:446:13）

TypeError: Router.use() requires middleware function but got a Object at Function. (/Users/ethanthomas/Desktop/mean-stuff/express-server/node_modules/express/lib/router/index.js:446:13)

不完全理解它要求我实施？

login_routes.js：

var express = require('express');
var app = express();

app.route('/login')

.get(function(req, res, next) {
    res.send('this is the login form');
})

.post(function(req, res, next) {
    console.log('processing');
    res.send('proccessing the login form!');
});

server.js：

var express = require('express');
var app = express();
var path = require('path');
var adminRoutes = require('./app/routes/admin_routes');
var loginRoutes = require('./app/routes/login_routes');

app.use('/admin', adminRoutes);
app.use('/login', loginRoutes);


//send our index.html file to the user for the home page
app.get('/', function(req, res) {
    res.sendFile(path.join(__dirname + '/index.html'));
});

//start the server
app.listen(1337);
console.log('leet is the magic port');

推荐答案

您的 login_routes.js 应该看起来像这样（在快递的上下文中）：

Your login_routes.js should look something like this (in the context of express):

var express = require('express');
var router = express.Router();

// GET request to /login
router.get('/', function(req, res, next) {
    // do something
});

// POST request to /login
router.post('/', function(req, res, next) {
    // do something
});

module.exports = router;

在 app.js 中，您使用

In your app.js you use

var login_routes = require('./login_routes');
...
app.use('/login', login_routes);
...

看看在代码由 express-generator 模块生成。这是快递网络服务器应用程序的起点。

Have a look at the code generated by the express-generator module. That is a starting point for express webserver apps.
