保留Azure Batch的输出文件时出现FileUploadMiscError

我在尝试将日志文件从Azure Batch执行持久保存到Azure Blob存储时遇到以下错误-“ FileUploadMiscError-上载输出文件之一时遇到其他错误”。此错误不会提供很多有关可能出问题的信息。我尝试检查Microsoft文档中的此错误代码,但未提及此特定错误代码。 下面是用于将任务添加到Azure批处理的相关代码,我已将其从C#移植到Python以持久保存日志文件。

注意:添加任务时会创建我配置的容器,但是里面没有斑点。

批处理的OutputFile处理中存在一个错误,如果完整的容器URL包含除SAS令牌中所包含的查询字符串以外的任何查询字符串参数,都会导致其无法上传到容器。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。

这个问题刚刚提出来,我们将在接下来的几周内发布修复程序,但是一个简单的解决方法是使用make_container_url来制作URL,而不是使用{{1} }。

生成的URL应该如下所示:container_url = 'https://{}/{}?{}'.format(blob_service.primary_endpoint, blob_details['container_name'], container_sas)-特别是它不应包含https://<account>.blob.core.windows.net/<container>?se=2019-01-12T01%3A34%3A05Z&sp=w&sv=2018-03-28&sr=c&sig=<sig>(这是restype=container软件包所包含的内容)
