javascript - 如何从 Android phonegap 应用程序中的 https URI 下载文件？

Question

如何在android中使用https协议(protocol)下载文件？我正在尝试使用它，但一直出现错误。

我的下载码:

var fileTransfer = new FileTransfer();
          fileTransfer.download(
                task_url,
                fileListDir + fileName,
            function(entry) {
                mylog("download complete: " + entry.fullPath);
            },
            function(error) {
                mylog("download error source " + error.source);
                mylog("download error target " + error.target);
                mylog("upload error code" + error.code);
            });

答案是将旧的 cordova 更改为 cordova 2.2.0 并在代码中写入 true，一些这样

var fileTransfer = new FileTransfer();
      fileTransfer.download(
            task_url,
            fileListDir + fileName,
        function(entry) {
            mylog("download complete: " + entry.fullPath);
        },
        function(error) {
            mylog("download error source " + error.source);
            mylog("download error target " + error.target);
            mylog("upload error code" + error.code);
        }, true);

这是工作!!!谢谢西蒙麦克唐纳!!
