Rails messing up with HTTP POST Params

Question

Our app provides an API that people can use to submit URLs like this:

curl -X POST http://app.local/resource -d'url=http://news.google.com/newshl=en&q=obama&um=1&ie=UTF-8&output=rss' 

Unfortunately, it seems that Rails messes up with this param. Any idea on how to fix this? See the log below :

Processing ApplicationController#index (for 127.0.0.1 at 2010-06-08 19:03:09) [POST]
  Parameters: {"um"=>"1", "url"=>"http://news.google.com/newshl=en", "output"=>"rss", "q"=>"obama", "ie"=>"UTF-8"}

I would expect the following :

  Parameters: {"url"=>"hhttp://news.google.com/newshl=en&q=obama&um=1&ie=UTF-8&output=rss"}

What exactly Rails messes up?

If you are referring to the fact that it didn't get complete Google URL (i.e. separated it to output, q and other params) that's because you need to encode '&' character if you want to use it as a part of a value. Something like:

curl -X POST http://app.local/resource -d'url=http://news.google.com/newshl=en%26q=obama%26um=1%26ie=UTF-8%26output=rss'
