我正在正确处理Express项目,目前我有app.js,socket文件夹在哪里,但是我的所有逻辑都在bin / www中,因为我在这样的路由中使用了套接字:
req.io.emit('dataUpdated', { id: client });
但是我想将其分离到app.js中,如何在不破坏我的应用程序的情况下做到这一点。
这是我的www文件:
var express = require('express');
var path = require('path');
var logger = require('morgan');
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
var config = require('../config.json');
var appRoutes = require('./routes/Approutes');
var app = express();
app.use(express.static(path.join(__dirname, '../public')));
mongoose.Promise = global.Promise;
mongoose.connect('localhost/db_test');
app.set('views', path.join(__dirname, '../views'));
app.set('view engine', 'hjs');
app.set('appProperties', {
secret: config.secret
});
var siofu = require("socketio-file-upload");
app.use(siofu.router);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
var debug = require('debug')('express-seed:server');
var server = require('http').Server(app);
/**
* Get port from environment and store in Express.
*/
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
/**
* Set socket
*/
var socketioJwt = require('socketio-jwt');
var socketIo = require('socket.io');
var io = socketIo.listen(server);
io.use(socketioJwt.authorize({
secret: config.secret,
handshake: true
}));
app.io = io;
app.use(function(req, res, next) { 'use strict'; req.io = io; next(); });
app.use('/', appRoutes);
require('../sockets/user')(io);
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
/**
* Normalize a port into a number, string, or false.
*/
function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
}
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
var bind = typeof addr === 'string'
? 'pipe ' + addr
: 'port ' + addr.port;
debug('Listening on ' + bind);
}
我的app.js文件为空... 和我的套接字文件
exports = module.exports = function (io) {
io.sockets.on('connection', (socket) => {
socket.on('clientGetList', (req) => {
// getting clientList
});
})
}
如何在不破坏应用程序的情况下将逻辑从www文件迁移到app.js文件?
答案 0 :(得分:1)
我想将中间件和套接字连接移至app.js和www中,以启动服务器
您可以这样分离代码,并将app
和server
变量都传递到app.js
模块,在该模块中,它可以运行其余的初始化代码(中间件,路由,套接字)。 io设置等...):
// www
const express = require('express');
const app = express();
const server = require('http').Server(app);
const port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
// load app.js and let it do it's part of the initialization of app and server
require('./app.js')(app, server);
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
/**
* Normalize a port into a number, string, or false.
*/
function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
}
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
var bind = typeof addr === 'string'
? 'pipe ' + addr
: 'port ' + addr.port;
debug('Listening on ' + bind);
}
然后,这将是app.js的概述:
const bodyParser = require('body-parser');
const siofu = require("socketio-file-upload");
const config = require('../config.json');
const appRoutes = require('./routes/Approutes');
const socketioJwt = require('socketio-jwt');
const socketIo = require('socket.io');
// export one function that gets called once as the server is being initialized
module.exports = function(app, server) {
app.set('views', path.join(__dirname, '../views'));
app.set('view engine', 'hjs');
app.set('appProperties', {
secret: config.secret
});
app.use(siofu.router);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
var io = socketIo.listen(server);
io.use(socketioJwt.authorize({
secret: config.secret,
handshake: true
}));
app.io = io;
app.use(function(req, res, next) { 'use strict'; req.io = io; next(); });
app.use('/', appRoutes);
require('../sockets/user')(io);
}
