从 Azure Batch 保留输出文件时出现 FileUploadMiscError

Question

我在尝试将日志文件从 Azure Batch 执行保存到 Azure Blob 存储时遇到以下错误 - "FileUploadMiscError - A miscellaneous error was encountered while uploading one of the output files"。这个错误并没有提供很多关于可能出了什么问题的信息。我尝试查看 Microsoft 文档以了解此错误代码，但并未提及此特定错误代码。下面是将任务添加到 Azure Batch 的相关代码，我已将其从 C# 移植到 Python 以保留日志文件。

注意：我配置的容器是在添加任务时创建的，但是里面没有blob。

import azure.storage.blob.models as blob_model
import yaml
from azure.batch import models
from azure.storage.blob.baseblobservice import BaseBlobService
from azure.storage.common.cloudstorageaccount import CloudStorageAccount
from dotenv import load_dotenv

LOG = logging.getLogger(__name__)


def add_tasks(batch_client, job_id, task_id, io_details, blob_details):

    task_commands = "This is a placeholder. Actual code has an actual task. This gets completed successfully."

    LOG.info("Configuring the blob storage details")
    base_blob_service = BaseBlobService(
        account_name=blob_details['account_name'],
        account_key=blob_details['account_key'])
    LOG.info("Base blob service created")

    base_blob_service.create_container(
        container_name=blob_details['container_name'], fail_on_exist=False)
    LOG.info("Container present")

    container_sas = base_blob_service.generate_container_shared_access_signature(
        container_name=blob_details['container_name'],
        permission=blob_model.ContainerPermissions(write=True),
        expiry=datetime.datetime.now() + datetime.timedelta(days=1))
    LOG.info(f"Container SAS created: {container_sas}")

    container_url = base_blob_service.make_container_url(
        container_name=blob_details['container_name'], sas_token=container_sas)
    LOG.info(f"Container URL created: {container_url}")

    # fpath = task_id + '/output.txt'
    fpath = task_id

    LOG.info(f"Creating output file object:")
    out_files_list = list()

    out_files = models.OutputFile(
        file_pattern=r"../stderr.txt",
        destination=models.OutputFileDestination(
            container=models.OutputFileBlobContainerDestination(
                container_url=container_url, path=fpath)),
        upload_options=models.OutputFileUploadOptions(
            upload_condition=models.OutputFileUploadCondition.task_completion))

    out_files_list.append(out_files)
    LOG.info(f"Output files: {out_files_list}")

    LOG.info(f"Creating the task now: {task_id}")
    task = models.TaskAddParameter(
        id=task_id, command_line=task_commands, output_files=out_files_list)

    batch_client.task.add(job_id=job_id, task=task)
    LOG.info(f"Added task: {task_id}")

Batch 的 OutputFile 处理中存在一个错误，如果完整的容器 URL 包含除 SAS 令牌中包含的参数之外的任何查询字符串参数，它会导致无法上传到容器.不幸的是，azure-storage-blob Python 模块在通过 make_container_url.

生成 URL 时包含一个额外的查询字符串参数

我们刚刚收到这个问题，将在未来几周内发布修复程序，但一个简单的解决方法是不要使用 make_container_url 制作 URL，而是自己制作所以：container_url = 'https://{}/{}?{}'.format(blob_service.primary_endpoint, blob_details['container_name'], container_sas).

结果 URL 应该看起来像这样： https://<account>.blob.core.windows.net/<container>?se=2019-01-12T01%3A34%3A05Z&sp=w&sv=2018-03-28&sr=c&sig=<sig> - 具体来说它不应该有 restype=container （这是 azure-storage-blob 包中包含的内容)
