我已经设置了新的express(nodejs)项目,当我尝试运行url时,它向我显示404找不到错误的错误。但我没有修改任何单行代码和目录结构。我使用了express-generator命令来创建快速项目的结构。
有人能为我提供以下问题的建议吗? - 为什么默认代码不运行? - 我应该如何设置我的项目目录以防止写这个长网址。 - 我如何将我的聊天应用程序与yii1项目集成。
以下是我的代码详情。
网址:http://localhost:3000/wchat/wnode/users
目录结构: wchat / wnode /用户 wchat:php项目 wnode:节点目录,用于实现即时通知和聊天 用户:模块
代码文件: app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
index.js
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
users.js
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
module.exports = router;

答案 0 :(得分:4)
看看你的路线,
app.use('/', routes); -> handlers GET on localhost:3000
app.use('/users', users); -> handles GET on localhost:3000/users
所以没有什么可以处理localhost:3000/wchat/wnode/users
。因此404。
如果你想处理像localhost:3000/wchat/wnode/users
这样的事情,
你需要一个像
router.verb('/wchat/wnode/users', function (req, res, next) {
// handle whatever you want.
});
查看您的代码以及您尝试获取的网址,我建议您熟悉快速处理路由的方式。更多信息here
