Question

当我尝试使用Azure门户UI在特定虚拟网络子网中创建池时，它可以工作，我可以从这些计算节点访问同一子网上的其他VM。但是，如果我尝试使用Python SDK这样做：

new_pool = batch.models.PoolAddParameter(
            id=pool_id,
            virtual_machine_configuration=batch_models.VirtualMachineConfiguration(
                image_reference=image_ref_to_use,
                node_agent_sku_id=sku_to_use),
            vm_size=constants._POOL_VM_SIZE,
            target_dedicated_nodes=constants._POOL_NODE_COUNT,
            max_tasks_per_node=2,
            task_scheduling_policy=batch.models.TaskSchedulingPolicy(
                node_fill_type=batch.models.ComputeNodeFillType.pack),
            start_task=batch.models.StartTask(
                command_line=azure_helper.wrap_commands_in_shell('linux', task_commands),
                user_identity=batch_models.UserIdentity(auto_user=user),
                wait_for_success=True,
                resource_files=self.application_files),
            network_configuration=batch_models.NetworkConfiguration(subnet_id=constants.AZURE_BATCH_SUBNET_ID),
        )

        try:
            self.batch_client.pool.add(new_pool)
        except batch_models.batch_error.BatchErrorException as err:
            print_exception()
            raise

它给了我azure.batch.models.batch_error.BatchErrorException: {'lang': u'en-US', 'value': u'Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.\nRequestId:xxxxxxxxxxxxxxxxxxxxxxx\nTime:2018-02-01T15:36:25.5107368Z'}

如果我在创建池时未指定network_configuration参数，则它适用于Python SDK。我的子网ID的格式为/subscriptions/xxxxxxxxxxxxxxxx/resourceGroups/xxxxx-compute/providers/Microsoft.Network/virtualNetworks/xxxxx-compute-vnet/subnets/default

有人能指出我为什么会这样吗？手动创建池很麻烦，因为我要添加许多资源文件URL。

谢谢！

Joining your compute pool with a Virtual Network requires authenticating with Azure Active Directory. Please see this article for more information. The AAD requirement is listed in the pre-requisites section of that article. Please review that article fully as it underscores other important requirements and restrictions when joining a pool with a virtual network.

You can see a sample of authenticating with AAD with the Python SDK here.
