Twitter Viewer

This is my first project using http.request and openURL. Can anyone show me a tutorial that uses Parameter tables for http.request?

-- HTTP.REQUEST

-- Use this function to perform your initial setup
function setup()
    TwitterLogo = nil

end
-- This function gets called once every frame
function draw()
    -- This sets a dark background color 
    background(40, 40, 50)
font("AmericanTypewriter-Condensed")
fill(237, 237, 237, 255)
text("Double-Tap to load",WIDTH/2,HEIGHT/2)
if TwitterLogo ~= nil then
    sprite(TwitterLogo,WIDTH/2,HEIGHT/2,WIDTH,HEIGHT)
    openURL("http://www.twitter.com")
    end
--Do your drawing here

end

function didGetLogo(theImage,status,head)
    TwitterLogo = theImage
    print("Status: "..status)
    if status < 200 then
        print("Error")
        print("Error report: "..status)
        print("This is a "..status.." error")
        print("--------------------")
        else 
           if status > 201 then
                print("Error")
                print("Error Report: "..status)
                print("This is a "..status.." error")
                print("-------------------")
                end
                if status == 404 then
                    print("Please check your WiFi connection")
                    print("or check to see you have a valid link")
                    end
    end
    end
    function touched(t)
        if t.tapCount == 1 and t.state == ENDED then
    http.request("http://images.wikia.com/moshimonsters/images/a/a7/Twitter_Logo.jpg",didGetLogo)
            end
                if status == 200 then
        openURL("http://twitter.com")
        end
            end
