多个Websockets [英] Multiple Websockets
问题描述
我正在尝试在一个页面上使用两个websockets。这是我的代码：
I'm trying to use two websockets on one page. This is my code:
var pageViewWs = new WebSocket("ws://localhost:9002/pageView");
var sessionWs = new WebSocket("ws://localhost:9002/session");
pageViewWs.onmessage = function (event) {
alert("PageView");
};
sessionWs.onmessage = function (event) {
alert("Session");
};
仅显示PageView警报。在服务器端没有请求/ session，只有/ pageView。
Only the PageView alert appears. On the server side no requests are made to /session, only to /pageView.
现在，如果我切换var pageViewWs和var sessionWs，那么会显示会话警报的PageView。这不是因为它们是警报，我试图附加到身体和divs，我已经介入使用Firebug。似乎一次只能创建一个WebSocket，尽管在Firebug中，pageViewWs和sessionWs的属性看起来是相同的，除了它们的url。
Now, if I switch var pageViewWs and var sessionWs around then the Session alert is shown instead of the PageView. It is not because they are alerts, I've tried appending to the body and to divs and I've stepped through using Firebug. It seems that only one WebSocket can be created at a time although in Firebug the properties for pageViewWs and sessionWs appear the same with the exception of their url.
我只有在Firefox 15.0.1中对此进行了测试。是否存在某种Websocket限制，您一次只能运行一个？或者我的代码出了什么问题？
I've only tested this in Firefox 15.0.1. Is there some sort of Websocket limitation whereby you can only run one at a time? Or is something wrong with my code?
推荐答案
我遇到了通过同一个端口运行多个服务的同样问题。所以，我创建了一个 PHP库来执行此操作。
I faced the same problem to run multiple services through the same port. So, I created a PHP library to do this.
主机提供商的一些免费计划不允许您绑定到端口或允许您绑定到一个端口。如果是 OpenShift Cloud Server ，则只能绑定到端口8080.因此，无法运行多个WebSocket服务。在这种情况下， Francium DiffSocket 非常有用。
Some free plans of hosting providers don't allow you to bind to ports or allow you to bind to one port. In case of OpenShift Cloud Server, you can only bind to port 8080. So, running multiple WebSocket services is not possible. In this case, Francium DiffSocket is useful.
您可以使用 PHP库在同一端口上运行不同的服务名为 Francium DiffSocket 。
You can run different services on the same port using a PHP library called Francium DiffSocket.
设置Francium DiffSocket后，您可以使用不同的服务：
After setting up Francium DiffSocket, you can do this for using different services :
var chatWS = new WebSocket("ws://ws.example.com:8000/?service=chat");
var gameWS = new WebSocket("ws://ws.example.com:8000/?service=game");
这些服务是通过单一端口运行的一个例子：
An example are these services which are running through a single port :
- Finding Value Of Pi
- Advanced Live Group Chat With PHP, jQuery & WebSocket
- Live Group Chat With PHP, jQuery & WebSocket
