Python使用googletrans包进行翻译-AttributeError: ‘NoneType‘ object has no attribute ‘group‘&httpcore._except

问题分析

安装googletrans包：

pip install googletrans

默认版本是：3.0.0

第一个报错：httpcore._exceptions.ConnectTimeout: timed out 连接超时！

因为是外网googletrans默认访问URL是translate.google.com，所以修改URL：

# 导入google翻译接口工具
from googletrans import Translator

# 实例化翻译对象
translator = Translator(service_urls=['translate.google.cn'])

translator = Translator(service_urls=['translate.google.cn'])

第二个报错：

>>> from googletrans import Translator
>>> translator = Translator()
>>> translator.translate('안녕하세요.')

Traceback (most recent call last):
  File "", line 1, in <module>
    translator.translate('안녕하세요.')
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/client.py", line 172, in translate
    data = self._translate(text, dest, src)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/client.py", line 75, in _translate
    token = self.token_acquirer.do(text)
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/gtoken.py", line 180, in do
    self._update()
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/googletrans/gtoken.py", line 59, in _update
    code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
AttributeError: 'NoneType' object has no attribute 'group'

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

解决办法

重新安装指定版本的googletrans==4.0.0-rc1

pip install googletrans==4.0.0-rc1

# 导入google翻译接口工具
from googletrans import Translator

# 实例化翻译对象
translator = Translator(service_urls=['translate.google.cn'])
# translator = Translator()

result = translator.translate('Hello', dest='zh-CN').text
print(result)
result = translator.detect('Hello').lang
print(result)
