Question

检索特定阿拉伯语关键字的Twitter数据时，如下所示：

#imports
from tweepy import Stream
from tweepy import OAuthHandler 
from tweepy.streaming import StreamListener

#setting up the keys
consumer_key = '………….' 
consumer_secret = '…………….'
access_token = '…………..'
access_secret = '……...'

class TweetListener(StreamListener):
    # A listener handles tweets are the received from the stream.
    #This is a basic listener that just prints received tweets to standard output

    def on_data(self, data):
        print (data)
        return True

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

    #printing all the tweets to the standard output
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_secret)

    stream = Stream(auth, TweetListener())
    stream.filter(track=['سوريا'])

我收到此错误消息：

Traceback (most recent call last):
File "/Users/Mona/Desktop/twitter.py", line 29, in <module>
stream.filter(track=['سوريا'])
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site- packages/tweepy/streaming.py", line 303, in filter
encoded_track = [s.encode(encoding) for s in track]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd8 in position 0: ordinal not in range(128)

请任何帮助!!

我查看了tweepy的源代码，并在Stream的源代码中找到了seems to cause the problem的行。该行来自过滤方法。当您在代码中调用stream.filter(track=['سوريا'])时，Stream会调用s.encode('utf-8')，其中s ='سوريا'（查看过滤器的源代码，您将使用utf-8作为默认编码）。此时代码抛出异常。

要解决此问题，我们需要使用Unicode字符串。

 t = u"سوريا"
 stream.filter(track=[t])

（为了清楚起见，我只是将你的字符串放入变量t）。

使用Python检索Twitter数据时出现Unicode解码错误
