Привязка триггера Azure Web PubSub для Функции Azure

[Function("Broadcast")]
public static void Run(
[WebPubSubTrigger("<hub>", WebPubSubEventType.User, "message")] UserEventRequest request, ILogger log)
{
    log.LogInformation($"Request from: {request.ConnectionContext.UserId}");
    log.LogInformation($"Request message data: {request.Data}");
    log.LogInformation($"Request message dataType: {request.DataType}");
}

[FunctionName("WebPubSubTrigger")]
public static void Run(
    [WebPubSubTrigger("<hub>", WebPubSubEventType.User, "message")] UserEventRequest request, ILogger log)
{
    log.LogInformation($"Request from: {request.ConnectionContext.UserId}");
    log.LogInformation($"Request message data: {request.Data}");
    log.LogInformation($"Request message dataType: {request.DataType}");
}

[Function("Broadcast")]
public static UserEventResponse Run(
[WebPubSubTrigger("<hub>", WebPubSubEventType.User, "message")] UserEventRequest request)
{
    return new UserEventResponse("[SYSTEM ACK] Received.");
}

[FunctionName("WebPubSubTriggerReturnValueFunction")]
public static UserEventResponse Run(
    [WebPubSubTrigger("hub", WebPubSubEventType.User, "message")] UserEventRequest request)
{
    return request.CreateResponse(BinaryData.FromString("ack"), WebPubSubDataType.Text);
}

const { app, trigger } = require('@azure/functions');

const wpsTrigger = trigger.generic({
    type: 'webPubSubTrigger',
    name: 'request',
    hub: '<hub>',
    eventName: 'message',
    eventType: 'user'
});

app.generic('message', {
    trigger: wpsTrigger,
    handler: async (request, context) => {
        context.log('Request from: ', request.connectionContext.userId);
        context.log('Request message data: ', request.data);
        context.log('Request message dataType: ', request.dataType);
    }
});

Определите привязку триггера в function.json.

{
  "disabled": false,
  "bindings": [
    {
      "type": "webPubSubTrigger",
      "direction": "in",
      "name": "data",
      "hub": "<hub>",
      "eventName": "message",
      "eventType": "user"
    }
  ]
}

Определите функцию в index.js.

module.exports = function (context, data) {
  context.log('Request from: ', context.bindingData.request.connectionContext.userId);
  context.log('Request message data: ', data);
  context.log('Request message dataType: ', context.bindingData.request.dataType);
}

app.generic('message', {
    trigger: wpsTrigger,
    handler: async (request, context) => {
          return {
              "data": "ack",
              "dataType" : "text"
          };
    }
});

module.exports = async function (context) {
  return {
    "data": "ack",
    "dataType" : "text"
  };
}
