Question

我试图在Express 4中找到路由器路由器。文档让它听起来很棒，但它不适合我。

如果我使用命令行工具制作标准应用程序，然后添加如下所示的routes / contacts.js：

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

router.route('/:contactid')
  .get(function(req, res) {
    res.send('(get) It worked '+contactid);
  })

module.exports = router;

然后在app.js中添加：

var contacts = require('./routes/contacts');

...

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

我希望http://localhost:8000/contacts/1与来自contacts.js的路线相匹配。但是，我收到的错误基本上表明它与contacts.js

中的任何路由都不匹配

Error: Not Found
    at Layer.app.use.res.render.message [as handle] (project1/app.js:31:15)
    at trim_prefix (project1/node_modules/express/lib/router/index.js:226:17)

如果我使用静态前缀添加路由，它会按预期工作：

router.get('/1', function(req, res) {
  res.send('It worked!');
});

// http://localhost:8000/contacts/1 says "It worked!"

关于我做错了什么的提示？

Answer 1

路由器路径相对于已安装的路径。所以你的联系人路由器只会是：

router.route('/:contactid')
  .get(function(req, res) {
    res.send('(get) It worked ' + req.params.contactid);
  })

我认为这应该有用（对我而言）

在routes / contacts.js

中

/* Created by matthias on 6/9/14. */
var express = require('express');
var router = express.Router();

router.get('/:contactid', function(req, res) {
        res.send('(get) It worked ' + req.params.contactid);
    });

module.exports = router;

然后在app.js

var contacts = require('./routes/contacts');
var app = express();
app.use('/contacts', contacts);

适合我：localhost：3000 / contacts /：3

可以预见到:(获得）它工作了3

Express.js 4路由与router.route不匹配
