Azure SignalR binding spec

Detailed documentation on the Azure SignalR binding component

配置

To setup Azure SignalR binding create a component of type bindings.azure.signalr. 请参阅本指南，了解如何创建和应用绑定配置。

  1. apiVersion: dapr.io/v1alpha1
  2. kind: Component
  3. metadata:
  4.   name: <NAME>
  5.   namespace: <NAMESPACE>
  6. spec:
  7.   type: bindings.azure.signalr
  8.   version: v1
  9.   metadata:
  10.   - name: connectionString
  11.     value: Endpoint=https://<your-azure-signalr>.service.signalr.net;AccessKey=<your-access-key>;Version=1.0;
  12.   - name: hub  # Optional
  13.     value: <hub name>

Warning

以上示例将 Secret 明文存储。 更推荐的方式是使用 Secret 组件， 这里。

元数据字段规范

字段必填绑定支持详情示例
connectionStringYOutputThe Azure SignalR connection string“Endpoint=https://<your-azure-signalr>.service.signalr.net;AccessKey=<your-access-key>;Version=1.0;”
hubNOutputDefines the hub in which the message will be send. The hub can be dynamically defined as a metadata value when publishing to an output binding (key is “hub”)“myhub”

绑定支持

该组件支持输出绑定，其操作如下:

  • create

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:

  1. {
  2.     "data": {
  3.         "Target": "<enter message name>",
  4.         "Arguments": [
  5.             {
  6.                 "sender": "dapr",
  7.                 "text": "Message from dapr output binding"
  8.             }
  9.         ]
  10.     },
  11.     "metadata": {
  12.         "group": "chat123"
  13.     },
  14.     "operation": "create"
  15. }
