UPDATE: Fixed puts statements. should have been x.token, not x.key.
I have gotten tired of twitterfeed not handling our RSS feed and tweeting our new posts. So have the other LosTechies members. I decided to finally learn OAuth so that I can write a script/app to handle tweeting our new blog posts.
This is the way I learned so bare with me.
First things first, is you have to go to twitter and login to your account. Once done, register your OAuth application and click the Register a new application link. This will set you up with an OAuth consumer key and secret; which we need to obtain the OAuth request token/secret and our ultimate goal of an OAuth access token/secret.
Required fields that I had to fill out were:
- Application Name
- Application Website
- Application Type (I chose Client)
- Default Access Type (I chose Read & Write)
- ReCaptcha at the bottom.
Once accepted you’ll be directed to a page displaying your consumer key and secret, like this:
I’ve looked at a few ways to do this and the easiest that I found was by using the twitter_oauth gem. Following the README for this gem I was able to get an access token/secret pretty easily.
I’m doing all of this through IRB because there is one part where you need to open a web page and allow your twitter client to post to Twitter.
~ > irb irb(main):001:0$ require 'rubygems' => true irb(main):002:0$ require 'twitter_oauth' => true irb(main):003:0$ client = TwitterOAuth::Client.new( irb(main):004:1* :consumer_key => 'YOUR_APP_CONSUMER_KEY', irb(main):005:1* :consumer_secret => 'YOURA_APP_CONSUMER_SECRET') ) => ...object output... irb(main):005:0$ request_token = client.request_token => ...object output... irb(main):006:0$ puts request_token.token, request_token.secret => [REQUEST_TOKEN] => [REQUEST_SECRET] irb(main):007:0$ request_token.authorize_url => http://twitter.com/oauth/authorize?oauth_token=TOKEN
Copy that url and put it into your browser of choice. When the “Deny” and “Allow” buttons become visible, click the “Allow” button. You will be presented with a numeric PIN. Copy that number into your clipboard because we’re going to use it on this final step to obtain the OAuth Access Token and Secret.
irb(main):007:0$ access_token = client.authorize( irb(main):008:1* request_token.token, irb(main):009:1* request_token.secret, irb(main):0010:1* :oauth_verifier => 'THE_NUMERIC_PIN_YOU_GOT_FROM_TWITTER' irb(main):0011:1* ) => ...object output... irb(main):0011:0$ puts access_token.token, access_token.secret => [ACCESS_TOKEN] => [ACCESS_SECRET] irb(main):0012:0$ client.authorized? => true
You now have everything you need to use the TwitterOAuth gem without having to authenticate everytime.
irb(main):0013:0$ client = TwitterOAuth::Client.new( irb(main):0014:1* :consumer_key => 'YOUR_CONSUMER_KEY', irb(main):0015:1* :consumer_secret => 'YOUR-CONSUMER-SECRET', irb(main):0016:1* :token => access_token.token, irb(main):0017:1* :secret => access_token.secret ) => ...object output... irb(main):0017:0$ client.authorized? => true
To tweet something after you have the client instance, just call the update method:
client.update('test tweet with OAuth')
That is how I figured out OAuth without a callback URL. Hacky, but it works.
