Heroku + socket.io 广播上的多个 dynos [英] Multiple dynos on Heroku + socket.io broadcasts

问题描述

我似乎遇到了一个问题，当我有 1 个以上的 dyno 时，我在 Heroku 上的 node.js 应用程序中的 socket.io 广播似乎不起作用.一旦我将其缩放到 1，它就会完美运行.有什么我需要知道的吗?也许有一种不同的方式可以向所有 dynos 广播?如果我需要提供更多信息或代码，请告诉我.

I seem to be having an issue where socket.io broadcasts in my node.js app on Heroku don't seem to work when I have more than 1 dyno. As soon as I scale it to 1, it works perfectly. Is there anything I need to know about this? Maybe there is a different way to broadcast to all dynos? Please elt me know if I need to provide more info or code.

推荐答案

如果您在多个 dynos/服务器上运行，那么您必须将 socket.io 配置为使用非内存会话存储，例如 RedisStore.socket.io 文档有详细信息，还有更多讨论此处.

If you're running on multiple dynos/servers then you have to configure socket.io to use a non-in-memory session store like the RedisStore. The socket.io documentation has details and there's more discussion here.
