首页 > 解决方案 > 使用 Azure 存储模拟器创建 Python `BlobClient.from_blob_url`?

问题描述

我正在尝试在以下场景中使用 Azure 存储模拟器:

  1. Blob 上传到模拟容器
  2. 上传 Blob 时创建的模拟事件网格消息
  3. 模拟队列存储接收事件网格消息
  4. 从队列存储消息触发本地运行的 Azure 函数

问题:

1 以上。工作正常(模拟器已启动并运行)

2 以上。是手动的,我不想下载和使用第三方事件网格模拟器。

    "event_type": "Microsoft.Storage.BlobCreated"
}

4 以上。函数触发但无法执行以下代码:

credentials = DefaultAzureCredential()

def create_blob_client(credentials):
        try:
            blob_client = BlobClient.from_blob_url(eg_msg_json['data']['blobUrl'], credentials, max_single_get_size = 256*1024*1024, max_chunk_get_size = 128*1024*1024)
            logging.info(f'####### Successfully created BlobClient #######')
        except:
            logging.error(f'####### Failed to create BlobClient  #######')
            logging.error(f'####### Blob URL: {eg_msg_json["data"]["blobUrl"]}  #######')
        return blob_client

错误:

谁能告诉我这里哪个是正确的?
