Description

Seems like Ruby on Rails doesn't like a Content-Type header along side a form-data multipart. It will attempt to convert normal form/data key/value pairs into a File Attachment (containing the value) instead.

In iPhone, this Content-Type header is not present and it works fine. So, for normal fields, we should be suppressing this header field to have the same behavior as iOS. Removing this field causes it to work OK.

How can Thomas reproduce this to move it to a resolved state?

the easiest way is to:
- build a simple RoR app that will print out the values of the incoming post fields. the non-file fields should be text
- post a mixed POST with both a file and key/value pairs

Thomas, I can also share the customer client code if you'd like.

I verified that this works on 1.5.0, Android 2.2 and 2.1. Here's my Rails controller code:

   class UploadController < ApplicationController
     def doit
       render :text => "got #{params[:file]} and also #{params[:hello]}, request:\n#{request}"
     end
   end

And the Titanium code:

   var xhr = Titanium.Network.createHTTPClient();
   var f = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory, 'KS_nav_ui.png');

   

   
   
   

   xhr.onerror = function(e) {

   Ti.API.info('IN ERROR ' + e.error);

   
   
   

   };
   xhr.onload = function(e) {

   Ti.API.info('IN ONLOAD ' + this.responseText);

   
   
   

   };
   // open the client
   xhr.open('POST','http://10.0.1.91:3000/upload/doit')">http://10.0.1.91:3000/upload/doit');
   
   

   // send the data
   xhr.send({image:f,hello:'hello world!',password:'sanford1000',message:'check me out'});
