杰迪socket.io:从服务器端捕获和发出事件 [英] GeddyJS & socket.io: catching and emitting events from server side

问题描述

我想和Geddy一起使用socket.io.我只是按照以下链接中的说明进行操作:

i would like to use socket.io along with Geddy. I just followed the instructions in the below link:

https://github.com/mde/geddy/wiki/Getting-started-with-Geddy,-Socket.io,-and-Authentication

建议我如何在服务器端捕获特定模型上的连接"事件.

Suggest me how to catch the 'connection' event on specific model in server-side.

还可以从下面一窥我到目前为止使用此模型所做的事情...

Also find below the glimpse of what i have did so far with this model...

geddy scaffold -rt LiveUpdate stat:string category:string

并在

geddy.io.addListenersForModels(['LiveUpdate']);
geddy.model.LiveUpdate.on('update', function (chat) { 
  ....

我真正需要的是知道如何从服务器端捕获或发出此模型的事件.

What i actually need is to know how to catch or emit events for this model from the server-side.

推荐答案

从Geddy中的模型和控制器发出socket.io事件非常简单:

Emitting socket.io events from models and controllers in Geddy is pretty simple:

• geddy.io.sockets.emit将向所有连接的客户端发出事件

• geddy.io.sockets.emit will emit an event to all connected clients

如果要侦听来自特定客户端的事件或将事件发送到特定客户端，则需要在应用程序的config目录中创建一个after_start.js文件，并像通常使用socket.io一样使用geddy.io:

If you want to listen for events from, or send events to specific clients, you'll need to create an after_start.js file in your app's config directory, and use geddy.io like you would normally use socket.io:

geddy.io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});
