我想从一个Datalake复制一个blob到另一个，下面是我的简单代码来完成这项工作：
DataLakeFileSystemClient sourceDataLakeFileSystemClient = StorageAccountDataLakeHelper.GetDataLakeFileSystemClient(SourceContainer, SOURCE_DATALAKE_NAME, SOURCE_DATA_LAKE_ACCESS_KEY);
DataLakeFileSystemClient taregetDataLakeFileSystemClient = StorageAccountDataLakeHelper.GetDataLakeFileSystemClient(TargetContainer, TARGET_DATALAKE_NAME, TARTGET_DATA_LAKE_ACCESS_KEY);
DataLakeDirectoryClient sourcedirectoryClient = sourceDataLakeFileSystemClient.GetDirectoryClient("folder1/folder2/");
DataLakeFileClient sourcefileClient = sourcedirectoryClient.GetFileClient("myfile.csv.csv");
Stream reader= await sourcefileClient.OpenReadAsync();
DataLakeDirectoryClient targetdirectoryClient = taregetDataLakeFileSystemClient.GetDirectoryClient("folder1/folder2/");
DataLakeFileClient targetfileClient = await targetdirectoryClient.CreateFileAsync("myfile.csv.csv");如您所见，基于访问密钥的身份验证。我可以成功地在本地运行这段代码。但是如果我在azure中发布一个函数应用程序，我会得到这样的异常：
An unhandled exception of type 'Azure.RequestFailedException' occurred in System.Private.CoreLib.dll
Service request failed.
Status: 403 (This request is not authorized to perform this operation.)
ErrorCode: AuthorizationFailure

Date: Wed, 28 Apr 2021 14:20:59 GMT此行发生异常：
Stream reader= await sourcefileClient.OpenReadAsync();我应该怎么做才能解决这个问题？
