Phonegap 3.0 FileTransfer download not working

Question

I'm downloading a multi-part mime encoded image to iOS like this:

var ft = new FileTransfer();
url = encodeURI(url);

ft.download(url, path, function(fileEntry) {}, function(err) {});

with

path = "file://localhost/var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg"

and get the following error:

body: "Could not create path to save downloaded file: The operation couldn’t be completed. (Cocoa error 513.)"
code: 1 (file not found)
http status: 200

This hints to an invalid path, but I can't see anything wrong with it. I get the path like this:

path = fs.root.toURL();

Everything else works fine and files can be stored in exactly the same path by taking photos. Just not via a FileTransfer download.

Any ideas or a bug in Phonegap 3.0? Thanks!

UPDATE - Workaround

FileWriter works and now even saves blobs on iOS and Android. Example code:

var xhr = new XMLHttpRequest();

xhr.open('GET', url, true);
xhr.responseType = 'arraybuffer';

xhr.onload = function() {
    var blob = new Blob([xhr.response], {type: 'image/jpeg'});

    // save via FileWriter
};

xhr.send();

Could you provide some code how you solved this problem? Is that a bug in Cordova? We have the same problem. — christianmenkens, Nov 19 '13 at 20:26
Don't know if FileTransfer works now, haven't tried in a while. See code example above. You need to know the mimeType to construct a correct blob, but that can be just text I guess. If you need a reference for the FileSystemAPI, look up Filer.js by Eric Bidelman. — Benjamin E., Nov 20 '13 at 03:12

I found the problem in iOS:

The path: path = "file://localhost/var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg"

does not work because it is an URL with "localhost" in it.

From FileEntry in Cordova one can get a string using "fullPath" and "toURL" ... on Android they work both to write a file. On iOS only the fullPath works ... the URL does not successfully write a file!

Hi @christianmenkens my i know what did you did on the success callback return to display it on image src? i got success but it returns var/mobile ... – BizApps Mar 12 '14 at 10:08
a path with file://var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg should be fine to work with on iOS. We are just using this path to put it into FileUpload. – christianmenkens Mar 20 '14 at 22:15
@christianmenkens are you sure there are just two slashes after file: ? I get three when requesting FS ... (and cocoa error 512.. works well on Android) – trainoasis Jul 08 '14 at 10:51

I use dirEntry.nativeURL+filename as the target for FileTransfer.download on iOS and Android and it works like a charm! – 695Multimedia Nov 14 '14 at 15:46

I had problems with that while working on the iOS Simulator, but once I tested it on the actual device, it worked.

use nativeURL to get the prefix and append your file name to it and pass it to FileTransfer object it will work.

You'll want to use FileEntry.toURL() to get a path that looks like this:

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

See the documentation here: https://github.com/apache/cordova-plugin-file-transfer
