由于 Twitter 更改了他们的 API，我必须控制原型自动售货机的脚本不再起作用，编写脚本的开发人员已经转向更环保的牧场。

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

当它识别出一条新推文时，它会向 Arduino 发送一个信号，Arduino 会触发一个螺线管来分发免费的产品样品（目前是防晒霜）

这行代码似乎是问题/过时的：

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，所以我有消费者密码和令牌代码等，但我仍然不知道如何使用这些 OAuth 代码修改旧代码以使其再次工作。我在下面完整复制了代码。任何人都可以帮助我并告诉我如何让这个脚本再次工作。

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，但您仍然需要将 twitter 键放入代码中。
