使用Azure异步Python SDK遍历VM列表时触发AttributeError

我编写了一个简单的异步Python程序，用于获取Azure订阅中的所有Virtual Machines列表，但在遍历VM列表时出现错误，而遍历Web应用列表则无异常。

完整程序代码 #

from azure.identity.aio import AzureCliCredential
from azure.mgmt.compute.aio import ComputeManagementClient
from azure.mgmt.network.aio import NetworkManagementClient
from azure.mgmt.web.aio import WebSiteManagementClient
from azure.mgmt.sql.aio import SqlManagementClient
import asyncio

credential = AzureCliCredential()

compute_client = ComputeManagementClient(credential, "XXXXX")
web_client = WebSiteManagementClient(credential, "XXXX")

async def get_as_list():
    as_list = web_client.web_apps.list()
    async for _as in as_list:
        pass
    return as_list
async def get_vm_list():
    vm_list = compute_client.virtual_machines.list_all()
    async for vm in vm_list:
        pass
    return vm_list

async def main():
    await get_as_list()
    await get_vm_list()

if __name__ == '__main__':
    asyncio.run(main())

解决方案 #

这个错误源于Azure Compute Management异步客户端的版本兼容问题，可通过以下步骤解决：

• 更新Azure Compute管理包到最新稳定版
  执行命令更新依赖：

  pip install --upgrade azure-mgmt-compute
  

• 显式指定API版本初始化客户端
  创建ComputeManagementClient时手动指定稳定API版本（如2023-07-01），规避默认版本的配置缺陷：

  compute_client = ComputeManagementClient(credential, "XXXXX", api_version="2023-07-01")
  

• 统一更新所有Azure异步SDK包
  确保所有相关Azure SDK包版本一致，避免跨版本兼容问题：

  pip install --upgrade azure-identity azure-mgmt-compute azure-mgmt-web azure-mgmt-network azure-mgmt-sql
  

Web应用列表遍历正常，是因为WebSiteManagementClient的SDK实现不存在该版本配置问题，默认API版本可正常调用。
