服务总线的 Azure 事件网格事件架构Azure Event Grid event schema for Service Bus

本文提供了服务总线事件的属性和架构。This article provides the properties and schema for Service Bus events. 有关事件架构的简介，请参阅 Azure 事件网格事件架构。 For an introduction to event schemas, see Azure Event Grid event schema.

有关示例脚本和教程的列表，请参阅服务总线事件源。For a list of sample scripts and tutorials, see Service Bus event source.

可用事件类型Available event types

服务总线发出以下事件类型：Service Bus emits the following event types:

事件类型Event type 说明Description
Microsoft.ServiceBus.ActiveMessagesAvailableWithNoListenersMicrosoft.ServiceBus.ActiveMessagesAvailableWithNoListeners 当队列或订阅中存在活动消息，但却没有接收器在侦听时会引发此事件。Raised when there are active messages in a Queue or Subscription and no receivers listening.
Microsoft.ServiceBus.DeadletterMessagesAvailableWithNoListenerMicrosoft.ServiceBus.DeadletterMessagesAvailableWithNoListener 当死信队列中存在活动消息，但却没有活动接收器时会引发此事件。Raised when there are active messages in a Dead Letter Queue and no active listeners.

示例事件Example event

以下示例显示了没有侦听器事件的活动消息的架构：The following example shows the schema of active messages with no listeners event:

[{
  "topic": "/subscriptions/{subscription-id}/resourcegroups/{your-rg}/providers/Microsoft.ServiceBus/namespaces/{your-service-bus-namespace}",
  "subject": "topics/{your-service-bus-topic}/subscriptions/{your-service-bus-subscription}",
  "eventType": "Microsoft.ServiceBus.ActiveMessagesAvailableWithNoListeners",
  "eventTime": "2018-02-14T05:12:53.4133526Z",
  "id": "dede87b0-3656-419c-acaf-70c95ddc60f5",
  "data": {
    "namespaceName": "YOUR SERVICE BUS NAMESPACE WILL SHOW HERE",
    "requestUri": "https://{your-service-bus-namespace}.servicebus.chinacloudapi.cn/{your-topic}/subscriptions/{your-service-bus-subscription}/messages/head",
    "entityType": "subscriber",
    "queueName": "QUEUE NAME IF QUEUE",
    "topicName": "TOPIC NAME IF TOPIC",
    "subscriptionName": "SUBSCRIPTION NAME"
  },
  "dataVersion": "1",
  "metadataVersion": "1"
}]

死信队列事件的架构类似：The schema for a dead letter queue event is similar:

[{
  "topic": "/subscriptions/{subscription-id}/resourcegroups/{your-rg}/providers/Microsoft.ServiceBus/namespaces/{your-service-bus-namespace}",
  "subject": "topics/{your-service-bus-topic}/subscriptions/{your-service-bus-subscription}",
  "eventType": "Microsoft.ServiceBus.DeadletterMessagesAvailableWithNoListener",
  "eventTime": "2018-02-14T05:12:53.4133526Z",
  "id": "dede87b0-3656-419c-acaf-70c95ddc60f5",
  "data": {
    "namespaceName": "YOUR SERVICE BUS NAMESPACE WILL SHOW HERE",
    "requestUri": "https://{your-service-bus-namespace}.servicebus.chinacloudapi.cn/{your-topic}/subscriptions/{your-service-bus-subscription}/$deadletterqueue/messages/head",
    "entityType": "subscriber",
    "queueName": "QUEUE NAME IF QUEUE",
    "topicName": "TOPIC NAME IF TOPIC",
    "subscriptionName": "SUBSCRIPTION NAME"
  },
  "dataVersion": "1",
  "metadataVersion": "1"
}]
