根“/”上的快速路由在 app.get 中不起作用

Question

I've been having this issue where for some reason the Express route doesn't see my root get function. I've declared my app.js this way:

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

Then in my index.js I have my definition this way:

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

router.get('/', function(req, res, next) {
  console.log('Enter root.');
});

router.get('/something', function(req, res, next) {
  console.log('Enter something.');
});

Express routes into '/something' just fine, but couldn't see '/' . Anybody have an idea why it doesn't work? Thanks.

Modified based on new info:

If you're getting a 304 status back in the browser, that's because the browser has cached the GET request and the server is telling the browser that the page has not been changed so the browser can just use the cached copy.

You can make the page uncacheable by changing the headers the server sends with the request.

See Cache Control for Dynamic Data Express.JS and NodeJS/express: Cache and 304 status code and Nodejs Express framework caching for more info.

You show no exports in index.js so this line:

var index = require('./app/routes/index');

does not accomplish anything. index is an empty object and thus this:

app.use('/', index);

doesn't do anything and, in fact, may even cause an error.

Perhaps what you want is this:

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

router.get('/', function(req, res, next) {
  console.log('Enter root.');
});

router.get('/something', function(req, res, next) {
  console.log('Enter something.');
});

// export your router
module.exports = router;

Then, index in your other file will be the router.
