Parsing params (one of the params value has ampersand)

Hello,

I am trying to parse a URL of this format

http://example.com/links?deal_id=161&url=http://another_example.com/index.php?route=product/product&product_id=275

I need to get 2 params

deal_id and url

However, in the above example, if I do params[:url], then I get "http://another_example.com/index.php?route=product/product"

product_id=275 is dropped on the floor as its considered another params....

CGI:escape for url is not an option since I have no choice in what I am being passed...

Any ideas?

1) Parse the entire query string yourself instead of using the params     hash

2) Explicitly retrieve params['product_id'] and (re)build the url param     as you need it in the controller.

3) Fix the request (as in #2) in a Rack middleware filter.

4) Tell the "no-choice" source of these malformed unescaped URLs      to read the damn RFCs :slight_smile:

HTH,
