有关文件传输（）问题下载的PhoneGap

问题描述

结果
我一直在开发一个应用程序的PhoneGap Android和iOS。我试图用下载文件传输（）下载从服务器中的文件（.PDF），它的正常工作。但是当我使用fileTransfer.onprogress话，好像下载超过文件的大小（我的文件为20MB，并下载40兆字节2倍以上）。

I have been developing a Phonegap App for Android and IOS. I am trying to download a file(.pdf) from server using FileTransfer() download, and it's working normally. But when I use fileTransfer.onprogress then it seems to download more than the size of the file (my file is 20Mb and it downloads 40Mb more than 2x).

fileTransfer.onprogress = function(progressEvent) {
    if (progressEvent.lengthComputable) {
        var percent = progressEvent.loaded/progressEvent.total;
        //percent allways equal 2, than more 2x size of real file
        console.log(percent);
    }
};
//Else FileTransfer() upload working well.

我不知道为什么？为什么会这样任何人都可以解释一下吗？

I don't known why? Can anyone explain to me why this is happening?
