我正在尝试关注 this tutorial to so connect to Google Analytics API .我一步一步地跟着一切。但是当我在 python 中运行模块时,出现以下错误:
Traceback (most recent call last):
File "C:\Users\me\Desktop\New folder (3)\HelloAnalytics.py", line 112, in <module>
main()
File "C:\Users\me\Desktop\New folder (3)\HelloAnalytics.py", line 106, in main
service_account_email)
File "C:\Users\me\Desktop\New folder (3)\HelloAnalytics.py", line 35, in get_service
service_account_email, key, scopes=scope)
File "C:\Python27\lib\site-packages\oauth2client\service_account.py", line 274, in from_p12_keyfile
with open(filename, 'rb') as file_obj:
TypeError: file() argument 1 must be encoded string without NULL bytes, not str
如果有人能指出我正确的方向,那就太好了。完整代码就在这里:

最佳答案
错误被追溯到ServiceAccountCredentials.from_p12_keyfile()
功能。它似乎在 service_account_email 字符串中检测到空值。您可以通过在第一个引号前加上“r”使其成为原始字符串:
service_account_email = r'<Replace with your service account email address.>'
或使用反斜杠“\”转义空值。
