为什么“Googletrans.Translator”突然停止工作？ [复制]

Question

几天前我在 Googletrans 中使用 Translator 功能写了几行。但是我今天试图重新运行这些行，它弹出了一系列错误......我对此感到非常困惑。如果您遇到过类似的问题，请在下方评论。欢迎任何帮助！

from googletrans import Translator
translator = Translator()
trans1 = translator.translate('Hello', dest = 'es')

我得到的错误如下：

AttributeError                            Traceback (most recent call last)
<ipython-input-19-c0f9e5495a2f> in <module>()
----> 1 trans1 = translator.translate('Hello', dest = 'es')

~\AppData\Local\Continuum\anaconda3\lib\site-packages\googletrans\client.py in translate(self, text, dest, src)
    170 
    171         origin = text
--> 172         data = self._translate(text, dest, src)
    173 
    174         # this code will be updated when the format is changed.

~\AppData\Local\Continuum\anaconda3\lib\site-packages\googletrans\client.py in _translate(self, text, dest, src)
     73             text = text.decode('utf-8')
     74 
---> 75         token = self.token_acquirer.do(text)
     76         params = utils.build_params(query=text, src=src, dest=dest,
     77                                     token=token)

~\AppData\Local\Continuum\anaconda3\lib\site-packages\googletrans\gtoken.py in do(self, text)
    178 
    179     def do(self, text):
--> 180         self._update()
    181         tk = self.acquire(text)
    182         return tk

~\AppData\Local\Continuum\anaconda3\lib\site-packages\googletrans\gtoken.py in _update(self)
     57         r = self.session.get(self.host)
     58         # this will be the same as python code after stripping out a reserved word 'var'
---> 59         code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
     60         # unescape special ascii characters such like a \x3d(=)
     61         if PY3:  # pragma: no cover

AttributeError: 'NoneType' object has no attribute 'group'

我试图对此错误消息进行研究，但一无所获。最让我困惑的是，这个简单的代码在 3 天前运行良好。但是当我今天早上打开时，我弹出了错误。请帮忙。非常感谢！

Answer 2

更新py-googletrans/googletrans/gtoken.py，如下所示：

RE_TKK = re.compile(r'TKK=eval\(\'\(\(function\(\)\{(.+?)\}\)\(\)\)\'\);',
                    re.DOTALL)
RE_RAWTKK = re.compile(r'tkk:\'([^\']*)\'',re.DOTALL)

def __init__(self, tkk='0', session=None, host='translate.google.com'):
    self.session = session or requests.Session()
    self.tkk = tkk
    self.host = host if 'http' in host else 'https://' + host

def _update(self):
    """update tkk
    """
    # we don't need to update the base TKK value when it is still valid
    now = math.floor(int(time.time() * 1000) / 3600000.0)
    if self.tkk and int(self.tkk.split('.')[0]) == now:
        return

    r = self.session.get(self.host)

    rawtkk = self.RE_RAWTKK.search(r.text)
    if rawtkk:
        self.tkk = rawtkk.group(1)
        return

Google 更改了创建令牌的方式。 在撰写本文时没有修复。 您必须等待 googletrans 更新。
