python - 'charmap' 编解码器无法编码字符

Question

我正在使用 tweepy，在屏幕上打印推文消息时出现此错误 (Windows)。

#!/usr/bin/env python

from tweepy import Stream
from tweepy import OAuthHandler
from tweepy.streaming import StreamListener
import json

#consumer key, consumer secret, access token, access secret.
ckey = 'xyz'
csecret = 'xyz'
atoken = 'xyz'
asecret = 'xyz'


class Listener(StreamListener):

    def on_data(self, data):
        print json.loads(data)['text']
        return True

    def on_error(self, status):
        print status


auth = OAuthHandler(ckey, csecret)
auth.set_access_token(atoken, asecret)

twitterStream = Stream(auth, Listener())
twitterStream.filter(track=['#hash1', '#hash2'], languages=['en'])

这是Windows不支持所有字符造成的。有解决办法吗？

Answer 1

您收到此错误，因为它无法打印 tweet.text 的 unicode 部分。将其编码为 utf-8 (unicode)。

def on_data(self, data):
    print json.loads(data)['text'].encode('utf-8')
    return True
