损坏的Python脚本通过Twi触发Arduino

Question

自从Twitter改变了他们的APi，我必须控制的一个原型自动售货机的脚本不再工作了，编写脚本的开发人员已经转向了更环保的牧场。在

该脚本每15秒扫描一次Twitter，搜索包含指定标签（当前设置为#sunshine）的最新tweet，并过滤掉任何转发。在

当它识别出一个新的tweet时，它会向一个Arduino发送一个信号，触发一个螺线管来分发免费的产品样本（目前是防晒霜）

这行代码似乎有问题/过时：

j =json.loads(urllib.urlopen('http://search.twitter.com/search.json?q='+searchTerm+'&result_type=recent&rpp=1&filter:retweets').read())

我已经在Twitter上注册了一个开发者帐户，所以我有了消费者的秘密和令牌代码等等，但是我仍然不知道如何用这些OAuth代码修改旧代码，使其重新工作。我已经在下面完整地复制了代码。有谁能帮我，告诉我如何让这个脚本再次运行。在

您发布的代码甚至没有使用twitter库。下面的代码已经过修改，实际上使用了twitter库，但是您仍然需要将twitter键放入代码中。在

from twitter import *
