简短版本：
这一小段代码从未回拨过。我在msdn这样的地方环顾四周，无法找到解决方案。在我看来，像BackgroundTransfer的BackgroundUploader的createUploadAsync的startAsync启动，但后来没有做任何事情。它没有错误或成功回调。
而且＆＃34;很少＆＃34;它实际上会再次停止工作几次。给设备一个硬重置似乎也解决了这个问题。网络连接通过本地局域网。与服务器的连接稳定。我在visual studio中的本地计算机上运行API的副本，请求成功运行。
我试图回归到cordova 5.1.1和cordova-plugin-file-transfer 1.3.0和1.2.0以查看它是否与我使用的版本有关。
我连接的服务器可与任何其他设备配合使用。值得注意的是，这整个功能似乎在Windows模拟器中工作，让我觉得这可能是一个特定的设备问题？
我可能已经削减了自己试图为Windows Phone 8.1进行流血的尝试
var uploader = new Windows.Networking.BackgroundTransfer.BackgroundUploader();
uploader.createUploadAsync(uri, transferParts).then(function(result) {
var uploadOperation = upload.startAsync();
fileTransferOps[uploadId].promise = uploadOperation;
uploadOperation.then(successFunc, errorFunc);
}, errorCallBack);
编辑： 我已经为此操作设置了超时，以便在25秒后中止，这样做。在所有其他（iOS / Android 4.2 / 5.x）设备上，这是即时的。由于某些原因，Windows Phone的速度并不慢，因为请求的时间超过60分钟。也许BackgroundUploader（）默默地失败......将会研究这个。
Edit2：在此处提交了错误报告：https://issues.apache.org/jira/browse/CB-10254 我试图帮助解决这个问题的其他方法是禁用时间和日期的同步，重新启动设备，它就像一个魅力......一会儿。进一步调试表明我的所有请求都已取消或待处理。
对于那些有兴趣帮助我深入了解这一点的人来说，下面是无聊的事。
代码示例：
$scope.album = {

var promises = [];

// Windows phone doesn't work so we have to add a dirty workaround, as usual.
if (ionic.Platform.isWindowsPhone()) {
photos[i] = "cdvfile://localhost/persistent/" + decodeURIComponent(photos[i].split("/").pop());
}
var scannInvoice = parseToBool($localstorage.get("remindInvoiceScan")) ? 1 : 0;
