问题 I have an existing web application on the standard PHP/Apache platform. Now, what I want is to add chat functionality, and I want it to be real-time over a websocket, and to that extend I've studied socket.io on nodejs a little bit. So in addition to Apache running the big PHP app, I would have nodejs with socket.io running chat. But what I don't really understand, is how would I recognise my users in the code for nodejs chat? For one, Apache and nodejs won't be able to run on the same port,

问题 I am developing chat application, using node.js socket.io module on a server, and javascript on a client. As it become more complex, I become tired to test different usage scenarios by clicking across browsers. At now I use different browsers in order to separate cookies. So in Firefox there is one chat participant, in Opera - second, etc. Therefore my question is: Can I automate this somehow? I've heard about headless testing engines like Phantom JS, Selenium WebDriver, but I don't know how
