Node Express - ＆＃34; req.params.name＆＃34;未定义

Question

在我基于Express和Node的项目中，当我访问http://localhost:3000/users/lbs时，req.params.name＆＃34;应该等于＆＃39; lbs＆＃39;但它是未定义的。

//app.js
app.use("/users/:name",username);

//username.js
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) {
    res.send('user: ' + req.params.name);
});
module.exports = router;

Answer 1

我认为您应该将其更改为：

//app.js
app.use("/users",username);

//username.js
var express = require('express');
var router = express.Router();
router.get('/:name', function(req, res) {
    res.send('user: ' + req.params.name);
});
module.exports = router;

Answer 2

试试这个解决方案：

//app.js
app.use("/users",username);

//username.js
var express = require('express');
var router = express.Router();
router.get('/:name', function(req, res) {
    res.send('user: ' + req.param('name'));
});
module.exports = router;
