Azure Logic应用-从Blob事件获取Blob内容

通过http:创建斑点时，我的逻辑应用程序会收到斑点事件.

My logic app receives a blob event when a blob is created via http:

我使用事件网格订阅，当Blob创建事件发生时，该订阅通过Webhook触发Logic App.

I use an Event Grid Subscription, which triggers the Logic App via webhook, when a Blob Created event occurs.

http触发器收到的典型blob事件如下:

A typical blob event received by the http trigger looks like:

[
  {
    "topic": "/subscriptions/xxxxxxx/resourceGroups/a-resource-group/providers/Microsoft.Storage/storageAccounts/ablobstorageaccount",
    "subject": "/blobServices/default/containers/testcontainer/blobs/9de2125e-5279-4375-bc60-c9987eb99251",
    "eventType": "Microsoft.Storage.BlobCreated",

      "sequencer": "00000000000000000000000000003D5300000000018067c3",

        "batchId": "be84f175-da20-4a44-8a8c-5d33a92fbcd3"
      }
    },
    "dataVersion": "",
    "metadataVersion": "1"
  }
]

如何通过设计器的获取blob内容操作使用此事件数据指定blob内容?

How can I use this event data to specify the blob content, using the Designer's Get blob content action?
