Using class CGI gives you access to HTML query parameters in two ways. Suppose we are given a URL of /cgi-bin/lookup?player=Miles%20Davis&year=1958. You can access the parameters ``player'' and ``year'' using CGI#[] directly:

require 'cgi'
cgi =
cgi['player'] ["Miles Davis"]
cgi['year'] ["1958"]

Or, you can retrieve all parameters as a Hash:

require 'cgi'
cgi =
h = cgi.params
h['player'] ["Miles Davis"]
