FineUploader上传到安卓设备上的Azure stall

Question

我正在尝试让FineUploader直接上载到Azure Blob存储。

我按照说明设置了一个演示页面，上面有上传程序，为CORS配置了我的blob存储帐户，并设置了一台SAS服务器。在桌面浏览器和我的iOS设备上，一切似乎都像预期的那样工作，但我的安卓设备上的上传似乎总是在8MB左右停滞不前。

有时摊位永远不会恢复，有时它似乎可以恢复，上传另一个~8兆，然后再次摊位。在任何一种情况下，它似乎在一个PUT上停留了2.2分钟。我不确定这个持续时间是否有任何意义，但到目前为止在我的测试中它是非常一致的。

我试过禁用和启用分块，大小为4MB，据我所知，它似乎对结果没有重大影响。

我在2个wifi网络和4g网络上尝试了2个Android设备(4.3和4.4)，结果相同。

我有与上传程序嵌入在它的网页暴露在以下网址：

http://fineuploadertest.blob.core.windows.net/cdn/index.htm (4兆字节)

index2.htm (禁用分块)和index3.htm (1兆块)位于同一目录中，如果您想要检查它们。

在这一点上，我的想法已经用完了，有没有其他人遇到过这个问题，或者有什么其他的想法可以让我尝试一下？

下面是我通过Chrome远程调试获得的一些调试输出，用于尝试(使用分块)失败。

put 1-7在2-4秒内成功，put 8停滞2.2分钟。声明的错误是"net::ERR_SSL_PROTOCOL_ERROR"，但我不确定这是否真的很重要，或者只是错误处理中的一个默认分支。

这个问题似乎不是fineuploader的错，而是SSL在Azure Blob Storage上的工作方式的结果，它只允许在单个HTTPS会话中传输特定数量的数据(在我的测试中大约是5兆)。

微软已经承认了issue，但目前还没有关于修复的预计时间。我不清楚为什么这个问题只影响SSL的某些实现。

同时，如果你需要允许更大的文件从浏览器上传到azure blob存储，并且在Android或其他浏览器上遇到问题，解决方法是：

1)如果您的用例不需要安全地传输数据，请切换到非SSL (HTTP)端点。

2)不要直接上传到blob存储，而是上传到自定义端点，然后让该端点将文件复制到blob存储。此终结点托管在Azure网站、Web角色或辅助角色中是可以的，此问题不会影响它们。
