'HTTP headers is not in the correct format' 使用 Python SDK 创建 Azure 容器时出错

Question

我正在尝试使用 Python SDK 和以下代码创建 Azure blob 容器。我在响应中收到 'ErrorCode:InvalidHeaderValue'。

我正在使用存储帐户 Azure 门户中 'Access Keys' 部分的 'ConnectionString'。而且我不认为连接是问题，因为这条线工作正常 blob_service_client = BlobServiceClient.from_connection_string(connection_string).

我为此使用了干净的 venv，下面是库版本蔚蓝核心==1.10.0 天蓝色存储 blob==12.7.1

import os
import yaml
from azure.storage.blob import ContainerClient, BlobServiceClient

def load_config():
    dir_root = os.path.dirname(os.path.abspath(__file__))
    with open (dir_root + "/config.yaml", "r") as yamlfile:
        return yaml.load(yamlfile, Loader=yaml.FullLoader)

config = load_config()
connection_string = config['azure_storage_connectionstring']

blob_service_client = BlobServiceClient.from_connection_string(connection_string)
blob_service_client.create_container('testing')

Traceback (most recent call last):
  File "/Users/anojshrestha/Documents/codes/gen2lake/project_azure/lib/python3.7/site-packages/azure/storage/blob/_container_client.py", line 292, in create_container

  File "/Users/anojshrestha/Documents/codes/gen2lake/project_azure/lib/python3.7/site-packages/azure/storage/blob/_generated/operations/_container_operations.py", line 134, in create
    raise HttpResponseError(response=response, model=error)
azure.core.exceptions.HttpResponseError: Operation returned an invalid status 'The value for one of the HTTP headers is not in the correct format.'

During handling of the above exception, another exception occurred:

Answer 1

如@kopaczew 所述，将 azure_storage_blob 恢复到 12.6.0 版本解决了我的问题。它似乎确实是最新的 azure-storage-blob 库的某种错误。不幸的是，上述问题并不仅限于 create_container 调用。回答我自己的问题，以防这对处于类似情况的其他人有所帮助。

我是如何解决我的问题的：

删除了我以前的venv环境（重新安装本身导致导入azure库时出现一些问题）
创建了新的 venv
pip install azure-storage-bob==12.6.0

Answer 2

您不需要重新安装。您可以通过在实例化任何客户端时设置 api_version 变量来解决此问题。

例如：

blob = BlobServiceClient(
    account_url="https://MY_BLOB_STORAGE.blob.core.windows.net",
    credential="MY_PRIMARY_KEY",
    api_version="2019-12-12", #or api_version='2020-02-10'
)
