我目前正在创建一个使用科尔多瓦3.1我的第一个web应用。林在这个相当新的，所以请裸跟我来。

林利用cordovas文档页面的文件传输code。 Everyting安装了CLI。
结果
这是多远我来：

Im using the file-transfer code from cordovas doc page. Everyting is installed with CLI.
This is how far i've come:

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
   download();
}    

function download(){
        var filePath = '/mnt/sdcard';
        var fileTransfer = new FileTransfer();
        var uri = encodeURI("https://www.dropbox.com/s/27bxw65u4ga5is0/test.pdf");

        fileTransfer.download(
            uri,
            filePath,
            function(entry) {
                console.log("download complete: " + entry.fullPath);
            },
            function(error) {
                console.log("download error source " + error.source);
                console.log("download error target " + error.target);
                console.log("upload error code" + error.code);
            },
            false,
            {
                headers: {
                    "Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
                }
            }
        );
}

config.xml中

config.xml

<access origin="*" />
<feature name="File">
<param name="android-package" value="org.apache.cordova.file.FileUtils" />
</feature>
<feature name="FileTransfer">
<param name="android-package" value="org.apache.cordova.filetransfer.FileTransfer" />
</feature>

和我的清单

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

I've spent almost 2 days now trying to solve this issue without success. So any help at all would be very apperciated.

编辑：解决

删除科尔多瓦3.1手动安装2.7.0，并得到​​它的工作。

Removed Cordova 3.1 and installed 2.7.0 manually and got it to work.

推荐答案

不知道约3.1，但科尔多瓦的最新版本（3.3+），较新（1.0.0+）版本文件的文件系统使用的网址，而不是文件路径。事情是这样的：

Not sure about 3.1, but for the latest version of Cordova (3.3+), the newer (1.0.0+) version of File uses filesystem URLs instead of the file path. Something like this:

cdvfile://localhost/persistent/path/to/file
