S3多部分上传：我怎样才能取消呢？ [英] S3 Multipart Upload: how can I cancel one?

问题描述

我需要取消正在进行的下载软件，与启动

I need to cancel an in-progress download that was initiated with

fileTransferUtility = new TransferUtility(/*...*/);
var uploadRequest = new TransferUtilityUploadRequest() /* config parameters... */
fileTransferUtility.BeginUpload(uploadRequest, new AsyncCallback(uploadComplete), file);

我已搜查SO和文件，但我不能找到一种方法...

I have searched SO and documentation, but I can't find a way...

理由：用户可以选择要上传的文件，并且可以选择一个非常大的文件，说1GB。我需要能够取消此

Rationale: the user can pick a file to upload, and may choose a very large file, say 1GB. I need to be able to cancel this.

在最坏的情况下，我可能只是试图杀死线程完全，或者关闭上传中不洁净的方式，但如何???

In the worst case, I could just try to kill the thread entirely, or shut down the upload in an unclean way, but how???

谢谢！

推荐答案

我收到的来自Amazon官方的回答的这一点。下面是他们的回答：

I received an official answer from Amazon on this. Here is their reply:

var fileTransferUtility = new TransferUtility(/* */);
var uploadRequest = new TransferUtilityUploadRequest();

Thread thread = new Thread(() => fileTransferUtility.Upload(uploadRequest));
Thread.Sleep(5000); // If not done in 5 seconds abort
if(thread.IsAlive)
    thread.Abort();

而不是使用 BeginUpload的 / EndUpload的呼叫，您需要使用上传呼叫包裹在一个线程，及协参照此主题。

Instead of using BeginUpload/EndUpload calls, you need to use a Upload call wrapped in a Thread, and heep the reference to this thread.

如果用户需要取消，叫中止（）线程，这将取消上传的。当然，你需要清洁的部分上传的文件（这些法案对他们！）。

If the user needs to cancel, call Abort() on the thread, which will cancel the upload. Of course, you need to clean partially uploaded files (they bill for them!).

据我的猜测：很简单的，直观的，但不是那么容易找到的：）

As I suspected: very simple and intuitive, but not so easy to find :)
