僕は直前になるまで、というか、実際に仕様変更されるまで気付かなかったわけですが、今月の頭からTwitterのBasic認証が使えなくなったそうですね。従って、Basic認証を用いてTwitterのAPIを使用しているBot達は、仕様変更の日を境に、屍と化してしまっているそうです。
僕が作ったtango! botなども同様に、Basic認証を利用していたので、屍と化してしまいました。ですが、tango! botにザオリクを唱えて欲しい(?)というご要望に応えまして、先週末にOAuth認証システムを実装しました。
で、せっかく実装したので、Simple Twitter Botを例にとって僕の実装例を次の場所に置いておきます。参考になるかどうかは甚だ疑問ではありますが、もし何かの参考になれたら幸いです。

*使い方(READMEから一部引用)
This bot runs in the following ways.
1. Search tweets using 'search_term' in Twitter.
2. Re-tweet the tweets.
HOW TO SETUP:
1. Register your OAuth client on Twitter
URL: http://twitter.com/oauth_clients
* you MUST choose 'client' for Simple Twitter Bot.
2. Run 'python register_pin.py' and
use CONSUMER_KEY and CONSUMER_SECRET you got from the registeration.
3. Change setting variables(e.g. CONSUMER_KEY, CONSUMER_SECRET) in main.py
4. Run Google App Engine dev_server and visit the following URL
URL: http://localhost:8080/cron/update
* If you finish all of your setting, set debug_flag in main.py off.
5. Done!
Enjoy developing your own twitter bot!
