我正在使用 google Channel API 和 appengine 进行小型聊天。有没有一种简单的方法可以知道有多少用户活跃在聊天中?
谢谢, 大卫

如果您要求跟踪有多少客户端连接到给定通道,答案应该很简单: 1. Channel API 不支持广播。
如果您询问如何跟踪客户端是否连接到通道,那么现在没有内置的方法可以做到这一点。您可以查看此问题的答案以获取更多信息:AppEngine Channel API - 检查通道是否仍然打开的最佳方式(服务器端)
Channel API 的存在(在上面提到)问题)很快就会到来。
If you're asking to track how many clients are connected to a given channel, the answer should be easy: 1. The Channel API doesn't support broadcast.
If you're asking for how to track whether a client is connected to a channel, there's not a built-in way to do that right now. You can see the answer to this question for more info: AppEngine Channel API - Best way to check if a channel is still open (server side)
Presence for the Channel API (referenced in the above question) is coming very, very soon.
