python - 搜索中文文本会抛出 UnicodeEncodeError

Question

我正在使用python-twiter使用 Twitter 的 API 搜索推文，但我遇到中文术语问题。这是重现该问题的最小代码示例:

# -*- coding: utf-8 -*-
import twitter

api = twitter.Api(consumer_key = "...", consumer_secret = "...",
                  access_token_key = "...", access_token_secret = "...")

api.VerifyCredentials()
print u"您说英语吗"
r = api.GetSearch(term=u"您说英语吗")

我收到此错误:

您说英语吗
Traceback (most recent call last):
          File "so.py", line 9, in <module>
    r = api.GetSearch(term=u"您说英语吗")

    json = self._FetchUrl(url, parameters=parameters)

    url = req.to_url()

    urllib.urlencode(query, True), fragment)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 1337, in urlencode
    l.append(k + '=' + quote_plus(str(elt)))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

Answer 1

GetSearch 中似乎存在错误:https://code.google.com/p/python-twitter/issues/detail?id=210 。我尝试用俄语(“Путин”)搜索“普京”，也得到了同样的错误。使用编码并没有帮助。

作为解决方法，您可以使用 twitter 包 ( https://github.com/sixohsix/twitter ):

# -*- coding: utf-8 -*-
from twitter import *

t = Twitter(auth=OAuth(token="...", token_secret="...", consumer_key="...", consumer_secret="...")))

print t.search.tweets(q=u"您说英语吗")
