Android Cordova FileTransfer.upload generates 503 errors with some web servers.

See:
https://github.com/apache/incubator-cordova-android/blob/master/framework/src/org/apache/cordova/FileTransfer.java
private void upload(final String source, final String target, JSONArray args
, CallbackContext callbackContext)

Cordova Android may have a bug with the way files are being sent. The
Android source code appears to use the built in java HttpURLConnection and
the developer who wrote the functionality decided to write the logic to
assemble the post data to be transfered. I examined two different post dumps
being sent to a web server running Nginx and Varnish. Notice how the
headers are different between *iOS *and *Android*.
I would suggest using
http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/DefaultHttpClient.html

Here are the two post dumps:

How odd but I have no choice but to believe in Google :)

Still I wish I would have seen these in the docs when I was writing the
initial code back in Android 2.x days. It would have made my life a lot
easier.

Re: Android Cordova FileTransfer.upload generates 503 errors with some web servers.

Posted by Andrew Grieve <ag...@chromium.org>.

I looked at switching to HttpClient when fixing some of the Android FT bugs
a while ago. According to this blog post (by an Android
dev), HttpURLConnection is recommended for gingerbread+.

Re: Android Cordova FileTransfer.upload generates 503 errors with some web servers.

Posted by Simon MacDonald <si...@gmail.com>.

Oh my crap. I swear this was not documented when I worked on the original
File Transfer code for Android. The entire FileTransfer plugin can be
re-written now to use actual tested code. The only thing we need do is to
keep the old method signatures.

If you are looking for me I'll be over in the corner kicking the cat.

Apache HttpClient is available to applications as part of the Android
platform, isn't it? Perhaps I've misunderstood.

org.apache.cordova.HttpHandler [1] makes use of HttpClient, but
HttpHandler itself doesn't appear to be referenced by any other Cordova
code.

I'd be happy to work on a pull request if it is in fact available
without adding a dependency.

Re: Android Cordova FileTransfer.upload generates 503 errors with some web servers.

I would have loved to have used the Apache HttpClient package but we are
trying to stay away from external dependencies.

When you set chunkedMode to false I know that the transfer worked as per
your comment on JIRA. I will update the docs to mention Nginx servers.
