Question

I have the following function that decodes a URL into a hash comprised of different pieces of the URL. For example, after the first line where I assign hash, I receive this output:

>> CGI.parse(URI.parse("http://google.com/?foo=bar&baz=hello").query)
=> {"foo"=>["bar"], "baz"=>["hello"]}

In this function, I’m trying to pull values if the key is “p” or “q”. I essentially want to filter the hash into only the keys and values I want.

My goal is to only show the keywords someone searches for such as brick or cement.

Here’s my function:

  def self.get_search_terms(search_url)
    hash = CGI.parse(URI.parse(URI.encode(search_url)).query) #returns a hash
    keywords = []
    hash.each do |key|
      if key["q"] != nil || 
        key["p"] != nil
        keywords << key
      end
    end
    keywords
  end

One way to do it:

def self.get_search_terms(search_url)
  hash = CGI.parse(URI.parse(URI.encode(search_url)).query)
  keywords = []
  hash.each do |key, value|
    if key == 'p' || key == 'q'
      keywords << value
    end
  end
  keywords
end
