在路由中使用socket.io [英] Using socket.io in routes

问题描述

我在我的角度应用程序和服务器之间使用了socket.io，没有任何麻烦，但是当我在路由中使用socket.io时，我不知道该怎么做.

I use socket.io between my angular app and my server without any trouble but I don't know how to do it when it comes to use socket.io in my routes.

这是我到目前为止所做的:

Here is what i did so far :

var server = app.listen(port);
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
socket.on('server',function(data){
    log.info(data.message);
});
socket.on('console',function(data){
    log.info(data.message);
});
socket.emit('client',{action:"test"});
});

正如我所说，它可以正常工作.

as i said , it works.

现在我想在我的一条路由中使用socket.io，这是从路由器加载的路由:

Now i want to use socket.io in one of my routes , routes loaded from my router :

require('./app/my.routes')(app,io);//i've tried to use it this way

my.routes.js

module.exports = function (app,io){ 
    io = app.get('io');//and get it this way
    io.sockets.emit('socket.io :: sucessfully passed from app to router')
    log.info('Trying to load express routes...');
    router.use(function (req, res, next) {
        next(); // make sure we go to the next routes and don't stop here
    });
    require('./models.mongoose/user');
    //require routes
    var consoleRoute = require('./express.routes/console.route')
   ...

现在我遇到了这个错误

io.sockets.emit('socket.io :: sucessfully passed from app to router')
  ^

TypeError: Cannot read property 'sockets' of undefined

很明显，我必须做错什么，但我不知道该怎么办. 有什么想法吗?

I must do something wrong obviously but I have no idea what. Any ideas ?

我也尝试过 app.set('io'，io) 在app.js和 app.get('io') 在另一边，但都失败了

I also tried app.set('io',io) in app.js and app.get('io') on the other side but it failed all the same

最后，我找到了解决方法，

Finally , i've found the solution,

app.io = io.sockets.on('connection', function (socket) {
socket.on('server', function (data) {
    log.info(data);
});
socket.emit('client', {
    action: "alert",
    text: 'test from socket io'
  });
});;

现在它已链接到应用程序，我可以在任何地方使用它.

Now it's linked to app, and I can use it anywhere.

推荐答案

您可以在快速配置文件中设置套接字io实现，并将"io"对象作为变量传递到应用程序中.

You can setup your socket io implementation in your express configuration file and pass your "io" object as a variable within the app.

app.io = io;

想法是做这样的事情:

module.exports = function (app){ 
    app.io.sockets.emit('socket.io sucessfully passed from app to router');
}
