当我添加的所有三个文件（dishRouter.js，promoRouter.js和app.js leaderRouter.js）显示了我下面的错误未处理的“错误”事件？
这是我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 dishRouter = require('./routes/dishRouter');
var promoRouter = require('./routes/promoRouter');
var leaderRouter = require('./routes/leaderRouter');
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);
app.use('/dishes',dishRouter);
app.use('/promotions',promoRouter);
app.use('/leadership',leaderRouter);
// 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;
这是dishRouter.js
var express = require('express');
var morgan = require('morgan');
var bodyParser = require('body-parser');
var hostname = 'localhost';
var port = 3000;
var app = express();
app.use(morgan('dev'));
var dishRouter = express.Router();
dishRouter.use(bodyParser.json());
dishRouter.route('/')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send all the dishes to you!');
})
.post(function(req, res, next){
res.end('Will add the dish: ' + req.body.name + ' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting all dishes');
});
dishRouter.route('/:dishId')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send details of the dish: ' + req.params.dishId +' to you!');
})
.put(function(req, res, next){
res.write('Updating the dish: ' + req.params.dishId + '\n');
res.end('Will update the dish: ' + req.body.name +
' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting dish: ' + req.params.dishId);
});
app.use('/dishes',dishRouter);
app.use(express.static(__dirname + '/public'));
app.listen(port, hostname, function(){
console.log(`Server running at http://${hostname}:${port}/`);
});
module.exports = dishRouter;
这是leaderRouter.js
var express = require('express');
var morgan = require('morgan');
var bodyParser = require('body-parser');
var hostname = 'localhost';
var port = 3000;
var app = express();
app.use(morgan('dev'));
var leaderRouter = express.Router();
leaderRouter.use(bodyParser.json());
leaderRouter.route('/')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send all the leaders to you!');
})
.post(function(req, res, next){
res.end('Will add the leader: ' + req.body.name + ' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting all leaders');
});
leaderRouter.route('/:leaderId')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send details of the leader: ' + req.params.leaderId +' to you!');
})
.put(function(req, res, next){
res.write('Updating the leader: ' + req.params.leaderId + '\n');
res.end('Will update the leader: ' + req.body.name +
' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting leader: ' + req.params.leaderId);
});
app.use('/leaders',leaderRouter);
app.use(express.static(__dirname + '/public'));
app.listen(port, hostname, function(){
console.log(`Server running at http://${hostname}:${port}/`);
});
module.exports = leaderRouter;
，这是promoRouter.js
var express = require('express');
var morgan = require('morgan');
var bodyParser = require('body-parser');
var hostname = 'localhost';
var port = 3000;
var app = express();
app.use(morgan('dev'));
var promoRouter = express.Router();
promoRouter.use(bodyParser.json());
promoRouter.route('/')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send all the promotions to you!');
})
.post(function(req, res, next){
res.end('Will add the promotion: ' + req.body.name + ' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting all promotions');
});
promoRouter.route('/:promotionId')
.all(function(req,res,next) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
next();
})
.get(function(req,res,next){
res.end('Will send details of the promotion: ' + req.params.promotionId +' to you!');
})
.put(function(req, res, next){
res.write('Updating the promotion: ' + req.params.promotionId + '\n');
res.end('Will update the promotion: ' + req.body.name +
' with details: ' + req.body.description);
})
.delete(function(req, res, next){
res.end('Deleting promotion: ' + req.params.promotionId);
});
app.use('/promotions',promoRouter);
app.use(express.static(__dirname + '/public'));
app.listen(port, hostname, function(){
console.log(`Server running at http://${hostname}:${port}/`);
});
module.exports = promoRouter;
但要加只有一个路由器，完美的作品，为什么呢？
我用的Win7，节点v4.4.5，NPM v3.9.0
是的，就是这样，现在的作品！非常感谢！ – Aleksandar
