PhoneGap文件传输错误1，在哪里写FileTransfers？ [英] PhoneGap File Transfer Error 1, where to write FileTransfers?

问题描述

相关：下载文件并将其存储在本地在sdcard使用PhonegapBuild ，但这个问题从未回答过。

Related to: Download File and store them locally in sdcard using PhonegapBuild but that questions has never been answered.

关于这个程序，我在写一个小应用程序，显示一堆pdf的，使用jquerymobile + phonegap编写，它正在使用phonegap构建服务。

About this app, I'm writing a little app that displays a bunch of pdf's, it's written using jquerymobile + phonegap and it's being build with the phonegap build service.

我意识到这个函数不能工作，因为根目录不是一个有效的地方写任何东西。但是，我无法得到我的应用程序的工作目录，也没有能够弄清楚什么是错误代码1的意思使用该文档。

I realize that this function cannot work, since the root-Directory is not a valid place to write anything. But, I was unable to get the working directory of my application, nor was I able to figure out what exactly Error Code 1 meant using the documentation.

从config.xml ：

from config.xml:

 <preference name="AndroidPersistentFileLocation" value="Internal" />

<preference name="permissions" value="none" />
<feature name="http://api.phonegap.com/1.0/file"/>
<feature name="http://api.phonegap.com/1.0/device" />


<gap:plugin name="org.apache.cordova.file" />
<gap:plugin name="org.apache.cordova.file-transfer" />

构建服务告诉我这些插件已成功添加。

And the build service tells me that these plugins have been sucessfully added.

打开apk并查看清单还会显示

Unpacking the apk and looking into the manifest also reveals that

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

已成功添加。

特别是使用

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

，然后只剩下实际的函数：

and then there is only the actual function left that would be to blame:

function downloadFile(name, url, y,x, canvasid, wrapperid){
   alert(name);
   window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
   function(fileSystem) {
      var directoryEntry = fileSystem.root; // to get root path to directory
      var rootdir = fileSystem.root;
      var fp = rootdir.fullPath;
      fp = fp+"/bestsongs/"+name;
      alert("downloading: " + url + " to " + fp);
      var fileTransfer = new FileTransfer();
      alert("downloading: " + url + " to " + fp);
      fileTransfer.download(
            url,
            name,
            function(theFile) {
                  alert("download complete: " + theFile.toURI());
                  loadPDF(theFile.toURI(), y,x, canvasid, wrapperid);
      },function(error) {
            alert("error: " + JSON.stringify(error));
      }
   );
   }, 
   function(arg) { 
      alert("FAIL ON requestFileSystem" + JSON.stringify(arg)); }
  );
}

 $(function() {
document.addEventListener("deviceready", function() {
       alert("deviceready!");
       try {
           alert(url);
           downloadFile(lyrics,url,y,x, 'the-canvas', 'wrapper');
       } catch(e) {
           alert(e);
       }
}, false);
});

使用警报，这里是我得到的：

Using the alerts, here is what I get:

deviceready!
<url> to file (which is right)
the name of the file.
downloading <url> to //bestsongs/<name>
downloading <url> to //bestsongs/<name>
error: {
        "code":1, 
        "source":<url>, 
        "target":<name>, 
        "http_status": null, 
        "body": null
       }
