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.new
|
cgi['player']
|
� |
["Miles Davis"]
|
cgi['year']
|
� |
["1958"]
|
Or, you can retrieve all parameters as a
Hash:
require 'cgi'
|
cgi = CGI.new
|
h = cgi.params
|
h['player']
|
� |
["Miles Davis"]
|
