“请求已提交”使用BackgroundUploadAsync时 [英] "The request has already been submitted" when using BackgroundUploadAsync

问题描述

您好，

我正在使用Windows Phone 8应用程序，我将设置文件上传到SkyDrive上的特定文件夹。我面临的问题是，在我的设备上，当我尝试使用BackgroundUploadAsync上传文件时，我收到一条错误消息："请求
已经提交。"奇怪的是，这在模拟器上工作正常。我已经在下面概述了我的步骤，希望有人可以看到我做错了什么。

I'm working on a Windows Phone 8 app in which I upload a settings file to a particular folder on SkyDrive. The problem that I'm facing is that on my device, when I attempt to upload the file using BackgroundUploadAsync, I get an error saying: "The request has already been submitted." Oddly, this works fine on the emulator. I've outlined my steps below in hopes that somebody can see what I'm doing wrong.

我首先获取文件夹ID（通过获取所有文件夹和文件来完成）根然后解析它以获取我的特定文件夹）

I first get the folder ID (accomplished by getting all of the folders and files at the root then parsing it to get my particular folder)

                LiveOperationResult e = await client.GetAsync("me/skydrive/files");
                IDictionary<string, object> resultDict = (IDictionary<string, object>)e.Result;
                List<object> items = (List<object>)resultDict["data"];
                foreach (object o in items)
                {
                    IDictionary<string, object> item = (IDictionary<string, object>)o;

                    if (item["name"].ToString() == "MyData")
                    {
                        folderID = item["id"].ToString();
                    }
                }

这对我来说总是有用。然后我按照请求将文件上传到该特定文件夹：

This always works for me. I then follow with a request to upload the file to that particular folder:

LiveOperationResult fileOpRes = await client.BackgroundUploadAsync(folderID, new Uri(filename, UriKind.Relative), OverwriteOption.Overwrite);

正如我上面所说的，这在模拟器中有效，但我收到"请求已经提交"，当我发送错误时部署到我的手机。

As I'd said above, this works in the emulator, but I get the "request has already been submitted" error when I deploy to my phone.

任何帮助？

谢谢！
