流星目前活跃的用户？ [英] meteor currently active users?

问题描述

我在流星上做了一个简单的聊天室。我如何获得当前活跃用户的列表？有没有办法真正获得当前连接/客户端的列表？

I'm making a simple chatroom in meteor. How would I get a list of currently active users? Is there a way to actually get a list of current connections / clients?

推荐答案

我昨天浏览了流星源，看看是否有已经是这样了。我找不到连接旗帜或任何东西......

I browsed the meteor sources yesterday to see if there is already anything like that. I couldn't find a connected flag or anything...

我认为你有两个选择：

• 在每个连接用户的客户端和服务器中实现心跳。我个人不太喜欢这个想法，因为这可能会导致数以万计服务器上运行的间隔时间。

• Implement a heartbeat in the client and the server for every connected user. I personally don't like this idea very much, as this could result in zillions of intervals running on your server.

使用 sockjs 服务器获取打开的套接字。 Meteor.default_server.stream_server.all_sockets（）返回一个包含所有已打开套接字的数组。您可能只有一个间隔寻找其中的更改（或者您将更好地监听sockjs服务器本身的更改，有一个可能有用的 register 方法） ，将打开的套接字映射到您的用户，并使用集合将其推送到您的客户端。
每个客户都知道他的套接字ID，所以映射不应该很难。

Use the sockjs server to get the open sockets. Meteor.default_server.stream_server.all_sockets() returns an array with all opened sockets. You could than have a single interval looking for changes in that (or better you'll listen to changes of the sockjs server itself, there is a register method that could be useful), map the open sockets with your users and use a collection to push it to your clients. Each client knows his socket id, so the mapping shouldnt be to hard.

我没有实现它，所以这些只是想法从哪里开始。

I didn't implement it yet, so these are only ideas where to start.
