节点JS无法获取/

Question

I am following this Node JS tutorial, but I have encountered a problem where I get the response Cannot GET / instead of Hello . Here is the structure for my code:

myapp/
├── app
│   └── routes
│       ├── index.js
│       └── note_routes.js
├── conf
│   ├── httpd-app.conf
│   └── httpd-prefix.conf
├── htdocs
├── node_modules
│   ├── ...
├── package.json
├── package-lock.json
└── server.js

server.js looks like this:

const express = require('express');
const MongoClient = require('mongodb').MongoClient;
const bodyParser = require('body-parser');

const app = express();

const port = 3000;

require('./app/routes')(app, {});
app.listen(port, () => {
  console.log('We are live on ' + port);
});

index.js is this:

const noteRoutes = require('./note_routes');
module.exports = function(app, db) {
  noteRoutes(app, db);
  // Other route groups could go here, in the future
};

And note_routes.js looks like this:

module.exports = function(app, db) {
  app.post('/notes', (req, res) => {
    // You'll create your note here.
    res.send('Hello')
  });
};

As can be seen, this is a very simple setup. According to the above-linked tutorial, this should be enough and should respond with Hello . However, this is not the case.

I am almost 100% sure that the port is correct because there is some not-503 response.

What's wrong here, and how can I get this to work as intended?

Answer 1

Your app.post() in note_routes should be app.get() or if you plan on making post requests then you can chain it like

app.post()
   .get();

Answer 2

this is wrong on a whole new kind of level.

I would imagine you are starting your server with node server.js

firstly, server.js does not require index.js anywhere

note_routes should contain .get() NOT .post()

in your browser you should be visiting http://localhost:3000/notes NOT plain old http://localhost:3000
