Examples with oauth redirect or for oob

See example_google.lua and example_twitter.lua for working oob examples. You may use a proper token_ready-url if you want to use a website instead of an standalone application.

Example with single_token (without oauth redirect or long-lived token)

-- generate a accesstoken, by the single_token at
-- http://dev.twitter.com/pages/oauth_single_token
access, msg = consumer.getAccess(
    "fdgsdf908g7df98g7dfs9g7df98g7df9g8fdg98", -- oauth_token
    "89fdg80df78gdasd9as0dsa0ds21kjh321kj3h12" -- oauth_token_secret 
)

-- now call a method!
return_value = access.call("method", {
    param = 'value',
    param2 = 'value2'
});
