Python 3.5.2，Tweepy 3.5.0，Windows 8.1

我正在关注senddex制作的教程，该教程展示了如何使用tweepy从Twitter流式传输数据。（他的教程是在Python 2中，但对Python 3来说很容易） -

但是，当我运行脚本时，它不会吐出任何数据。它会挂起，直到我得到一个3向IncompleteRead异常，或直到我执行Ctrl + C.

这是我的Listener类代码：

class listener(StreamListener):

    def on_date(self,data):
        try:
            print(data)
            save = open('twitDB.csv', 'a')
            save.write(data)
            save.write('\n')
            save.close()
            return True
        except BaseException as e:
            print('failed on data,',str(e))
            time.sleep(5)

    def on_error(self,status):
        print(status)

auth = OAuthHandler(ckey, csecret)
auth.set_access_token(atoken,asecret)
twitterStream = Stream(auth=auth, listener=listener())
twitterStream.filter(track=["car"])

正如您所看到的，我将其设置为在将其保存到csv时捕获错误并打印数据，但它实际上没有做任何事情，只是挂起。

另外，对于曲目，我确实尝试使用不太通用的东西，但它仍然被绞死。

引发KeyboardInterrupt时：

Traceback (most recent call last):
  File "C:\Program Files\Python35\lib\site-packages\requests\packages\urllib3\co
ntrib\pyopenssl.py", line 217, in recv_into
    return self.connection.recv_into(*args, **kwargs)

    raise WantReadError()

During handling of the above exception, another exception occurred:

KeyboardInterrupt

这是我第一次使用社交媒体API，所以如果我遗漏了一些明显的东西，我会道歉。感谢帮助，谢谢。

Answer 1

def on_date(self,data):

这应该是

def on_data(self,data):

Answer 2

没关系，当我将on_status与status.text一起使用时，它确实有用，必须是我所遗漏的东西。

为什么使用Python 3的Tweepy根本不会从流中返回任何数据？
