def
on_data(self, data):
print
data
return
True
auth = OAuthHandler(API_KEY, API_SECRET)
auth.set_access_token(TOKEN_KEY, TOKEN_SECRET)
stream = Stream(auth, Listener())
stream.filter(track=['child labor'])
下面，你需要添加代码，通过
on_data
方法，像本章之前那样将推文保存到数据库、文件
或其他的存储工具。

能够同应用编程接口进行交互是数据处理中很重要的一部分。在这一章中，我们学习了一
些
API
基础知识（见表
13-2
中的总结），并且处理了来自
Twitter API
的数据。
表13-2：API概念
概念 功能
REST API
（与流式
API
相比） 返回数据，并且暴露静态的节点
流式
API
（与
REST API
相比） 返回查询相关的实时数据
OAuth
和
OAuth2
给定一系列
key
值和
token
的认证
分级数据卷 数据频率限制
/
可用性的不同级别；一些需要付费
key
和
token
标识用户和应用的唯一
ID
和密钥
我们已经复用了许多已经知道的
Python
概念，并且在这一章中学习了一些新的
Python
概
念。首先是
tweepy
的使用，一个处理同
Twitter API
交互的库。你还学习了有关认证和
OAuth
协议的知识。
作为同
