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协议下载文件？我试着用它，但总是出错。

我的下载代码：

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);
});

Answer 1

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

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);

这就是工作！！！谢谢Simon Mac Donald！！
