Question

您好我正在尝试显示消息：使用路径文件夹/ user.js

中的资源进行响应

  exports.list = function (req, res) {
  res.send("respond with a resource");
  };

但是我在命令提示符下收到错误404.并在url中 localhost：8080 \ user发送响应的地方我收到消息：

无法获取/用户

我的app.js有代码：

var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');

var app = express();

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

// development only
if ('development' == app.get('env')) {
    app.use(express.errorHandler());
}

app.get('/', routes.index);
app.get('/users', user.list);

http.createServer(app).listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

您的路线名为/users 而不是 /user。因此，请尝试在浏览器中导航到/users，它应该可以正常工作。

res。发送它导致404错误？
