python - 使用 Python SDK 创建 Azure 容器时出现“HTTP 标头格式不正确”错误

问题描述

我正在尝试使用 Python SDK 和以下代码创建一个 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“访问密钥”部分的“连接字符串”。而且我认为连接不是问题，因为这条线工作正常blob_service_client = BlobServiceClient.from_connection_string(connection_string)。

我为此使用了一个干净的 venv，下面是库版本 azure-core==1.10.0 azure-storage-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

解决方案

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

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'
)
