将数据追加到所有Socket.io客户端发出的数据

Question

I'm working on a couple sites that share some Socket.io initialization code. Also shared is a global var. If this var has a value I need to send it over in all socket emits.

I have not been able to figure out a good way to append this variable to all outgoing emits. I was hoping that Socket.io would have a method that is called whenever an emit is fired (just before sending the data), allowing you to add to the data as needed. But, if it exists, I could not find it.

Any suggestions?

这很丑陋，但是您可以保存现有的代码，并编写自己的emit函数来执行所需的操作，然后调用原始的emit 。
