(Ruby) Twitter PIN-Based Authorization (Step 1)

Demonstrates the 1st step in Twitter PIN-based authorization using OAuth. The purpose of this step is to obtain a temporary request token that will be traded for an access token + secret in the final step. Once the access token + secret is obtained, the application can access the Twitter account in whatever ways it was authorized.

Note: This example requires Chilkat v11.0.0 or greater.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

http.put_OAuth1(true)
http.put_OAuthConsumerKey("my-consumer-key")
http.put_OAuthConsumerSecret("my-consumer-secret")

req = Chilkat::CkHttpRequest.new()
req.put_HttpVerb("POST")
req.put_ContentType("application/x-www-form-urlencoded")

resp = Chilkat::CkHttpResponse.new()
success = http.HttpReq("https://api.twitter.com/oauth/request_token",req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit

if (resp.get_StatusCode() == 200)

    oauthToken = resp.urlEncParamValue(resp.bodyStr(),"oauth_token")
    print "OAuth temporary request token = " + oauthToken + "\n";

    oauthTokenSecret = resp.urlEncParamValue(resp.bodyStr(),"oauth_token_secret")
    print "OAuth temporary token secret = " + oauthTokenSecret + "\n";

    oauthCbConfirmed = resp.urlEncParamValue(resp.bodyStr(),"oauth_callback_confirmed")
    print "OAuth callback confirmed  = " + oauthCbConfirmed + "\n";

    # At this point, the end-user needs to browse to the following
    # Twitter URL to log in to his/her Twitter account and get a PIN.
    # 
    # https://api.twitter.com/oauth/authenticate?oauth_token=OAUTH_TOKEN
    # 
    # (where OAUTH_TOKEN is replaced with the contents
    # of the OAuth temporary request token.)

    # Your application may have an embedded browser such
    # that it automatically navigates to the above URL, or it may
    # be necessary for the user to browse to this URL independently.

    # Once the PIN is obtained, your application should provide a means
    # for the end-user to enter it (by typing it into an input text box, for example), 
    # and then Step 2 (the final step) can begin.
