BackgroundUploader.GetCurrentUploadsForTransferGroupAsync（group）抛出“Operation Aborted”和“Operation Aborted”。例外 [英] BackgroundUploader.GetCurrentUploadsForTransferGroupAsync(group) throws an "Operation Aborted" exception
问题描述
大家好，
我正在使用IBackgroundTask将文件上传到服务器，我想更新上传信息给用户，所以我每2秒调用一次BackgroundUploader.GetCurrentUploadsForTransferGroupAsync获取上传信息。
I'm uploading files to a server using IBackgroundTask and I want to update upload information to user, so I call BackgroundUploader.GetCurrentUploadsForTransferGroupAsync every 2 seconds to get upload information.
此方法会抛出 "Operation Aborted"反复出现异常，因此我无法在很长一段时间内获得更新的转移信息（用户可能认为转移卡住了）但我找不到任何相关文档。
This method throws a "Operation Aborted" exception repeatedly, so I can't get updated information for transfer during a long time (user may think transfer is stuck) but I couldn't find any documentation about it.
1 - ）有谁知道为什么会这样？
1-) Does anyone know why this happens?
2-）有谁知道如何避免这个问题？
2-) Does anyone know how to avoid this problem?
最好的问候，
CJ
推荐答案
嗨CJ Santos，
Hi C.J. Santos,
由于我没有看到您的代码，所以我不确定问题出在哪里。请参阅官方代码示例"背景传输样本"。
在场景2中，它通过UploadOperation获取BackgroundUploadProgress。
Since I have not saw your code, so I’m not sure where the issue is. Please refer to the official code sample "Background transfer sample". In Scenario 2, it gets BackgroundUploadProgress via UploadOperation.
顺便提一下，每2秒调用一次BackgroundUploader.GetCurrentUploadsForTransferGroupAsync来获取上传信息。我认为这是不合理的。使用UploadOperation将是正确的方向。
By the way, you call BackgroundUploader.GetCurrentUploadsForTransferGroupAsync every 2 seconds to get upload information. I think it’s unreasonable. Use the UploadOperation would be on right direction.
