补充资料

By default the Azure SignalR output binding will broadcast messages to all connected users. To narrow the audience there are two options, both configurable in the Metadata property of the message:

  • group: Sends the message to a specific Azure SignalR group
  • user: Sends the message to a specific Azure SignalR user

Applications publishing to an Azure SignalR output binding should send a message with the following contract:

{
    "data": {
        "Target": "<enter message name>",
        "Arguments": [
            {
                "sender": "dapr",
                "text": "Message from dapr output binding"
            }
        ]
    },
    "metadata": {
        "group": "chat123"
    },
    "operation": "create"
}
