充当事件网格源的 Azure 服务总线Azure Service Bus as an Event Grid source

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.

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.
Microsoft.ServiceBus.ActiveMessagesAvailablePeriodicNotificationsMicrosoft.ServiceBus.ActiveMessagesAvailablePeriodicNotifications 如果在队列或订阅中存在活动消息，即使该特定队列或订阅上有活动侦听器，也会定期引发此事件。Raised periodically if there are active messages in a Queue or Subscription, even if there are active listeners on that specific Queue or Subscription.
Microsoft.ServiceBus.DeadletterMessagesAvailablePeriodicNotificationsMicrosoft.ServiceBus.DeadletterMessagesAvailablePeriodicNotifications 如果队列或订阅的死信实体中存在消息，即使该特定队列或订阅的死信实体上有活动侦听器，也会定期引发此事件。Raised periodically if there are messages in the dead-letter entity of a Queue or Subscription, even if there are active listeners on the dead-letter entity of that specific Queue or Subscription.

示例事件Example event

没有侦听器时有活动消息可用Active messages available with no listeners

如果队列或订阅中存在活动的消息，但却没有接收器侦听，则会生成此事件。This event is generated if you have active messages in a queue or a subscription and there are no receivers listening.

[{
  "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"
}]

没有侦听器时有死信消息可用Deadletter Messages Available With No Listener

死信队列事件的架构类似。The schema for a dead letter queue event is similar. 对于每个有消息但没有活动接收器的死信队列，你会至少收到一个事件。You get at least one event per dead-letter queue that has messages and no active receivers.

[{
  "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"
}]

活动消息可用定期通知Active Messages Available Periodic Notifications

如果在特定队列或订阅上具有活动消息，即使该特定队列或订阅上有活动侦听器，也会定期生成此事件。This event is generated periodically if you have active messages on the specific queue or subscription, even if there are active listeners on that specific queue or subscription.

[{
  "topic": "/subscriptions/<subscription id>/resourcegroups/DemoGroup/providers/Microsoft.ServiceBus/namespaces/<YOUR SERVICE BUS NAMESPACE WILL SHOW HERE>",
  "subject": "topics/<service bus topic>/subscriptions/<service bus subscription>",
  "eventType": "Microsoft.ServiceBus.ActiveMessagesAvailablePeriodicNotifications",
  "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-WILL-SHOW-HERE.servicebus.chinacloudapi.cn/TOPIC-NAME/subscriptions/SUBSCRIPTIONNAME/$deadletterqueue/messages/head",
    "entityType": "subscriber",
    "queueName": "QUEUE NAME IF QUEUE",
    "topicName": "TOPIC NAME IF TOPIC",
    "subscriptionName": "SUBSCRIPTION NAME"
  },
  "dataVersion": "1",
  "metadataVersion": "1"
}]

死信消息可用定期通知Deadletter Messages Available Periodic Notifications

如果在特定队列或订阅上具有死信消息，即使该特定队列或订阅的死信实体上有活动侦听器，也会定期生成此事件。This event is generated periodically if you have deadletter messages on the specific queue or subscription, even if there are active listeners on the deadletter entity of that specific queue or subscription.

[{
  "topic": "/subscriptions/<subscription id>/resourcegroups/DemoGroup/providers/Microsoft.ServiceBus/namespaces/<YOUR SERVICE BUS NAMESPACE WILL SHOW HERE>",
  "subject": "topics/<service bus topic>/subscriptions/<service bus subscription>",
  "eventType": "Microsoft.ServiceBus.DeadletterMessagesAvailablePeriodicNotifications",
  "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-WILL-SHOW-HERE.servicebus.chinacloudapi.cn/TOPIC-NAME/subscriptions/SUBSCRIPTIONNAME/$deadletterqueue/messages/head",
    "entityType": "subscriber",
    "queueName": "QUEUE NAME IF QUEUE",
    "topicName": "TOPIC NAME IF TOPIC",
    "subscriptionName": "SUBSCRIPTION NAME"
  },
  "dataVersion": "1",
  "metadataVersion": "1"
}]
