尝试将socket.io消息广播到所有已连接的套接字，例如房间 [英] Trying to broadcast socket.io message to all connected sockets in e.g. room

问题描述

挑战：

我想使用 SailsJS ，并能够通过socket.io加入房间，并且

I would like to use SailsJS, and be able to join a room, by means of socket.io, and receive unsolicited messages from this room, not just when one enters or leaves the room but also receive objects.

因此，几个客户端连接到服务器。
之后将消息/对象广播（从服务器启动）到每个房间，从而在这个房间里连接连接的插座。

So several clients connect to the server. Afterwards broadcast (initiated from the server) messages/objects to every room and thus everey connected socket in this room.

我也许可以只发送每个连接的插座一条消息，但非常希望获得一个示例，说明如何使用SailsJS 0.10做到这一点，以及使用SailsJS 0.10方式实现优雅的方法。

I maybe could just send every connected socket a message, but dearly would like a example on how to do this with SailsJS 0.10, and a elegant method in the SailsJS 0.10 way.

我正在查看： https://github.com/balderdashy/sailsChat ，但我认为这与模型本身非常接近，像例如：autosubscribe：['destroy'，'update']

I am looking at : https://github.com/balderdashy/sailsChat, but I think this is to close to the models themselves, with like e.g: autosubscribe: ['destroy', 'update']

在我看来，这应该更宽松地耦合，而不是与模型本身联系在一起。

In my opinion this should be more loosely coupled, and not so tied to the model itself.

谢谢！

I。

推荐答案

SailsChat 示例的目的是演示可能会从套接字消息中消除很多麻烦。您可以使用非常少量的后端代码在Sails中创建功能齐全的聊天应用程序，这一点令人印象深刻。对于不适合使用资源充足的pubsub的情况-或者如果您只是不想使用它-Sails会在 sails.sockets 命名空间。文档对其工作方式非常清楚。

The purpose of the SailsChat example is to demonstrate how Sails JS resourceful pubsub can take a lot of hassle out of socket messaging when you are mainly concerned with sending messages about models. The fact that you can make a full-featured chat app in Sails with very little back-end code is what makes it impressive. For situations where resourceful pubsub is not appropriate--or if you just plain don't want to use it--Sails exposes lower-level methods on the sails.sockets namespace. The docs are pretty clear on how they work.

要将套接字连接到任意房间，请执行 sails.sockets.join（< socket> ;，< roomName>），其中< socket> 是原始套接字（可能来自 req.socket 或套接字ID）。

To join a socket to an arbitrary room, do sails.sockets.join(<socket>, <roomName>), where <socket> is either a raw socket (probably from req.socket or a socket ID).

要将消息广播到房间中的所有套接字，请执行 sails.sockets。广播（< roomName> ;,<数据>）。

To broadcast a message to all sockets in a room, do sails.sockets.broadcast(<roomName>, <data>).

这些和更多方法在 Sails JS文档。
