我想修复此代码并解码脚本
from cryptography.fernet import Fernet
key = b'QBShfFGhSYZ9uC_G35ZdNLzNR0m_FDrTXxuo-fDljg0='
token = b'gAAAAABdLZ4U_F4a89F7rtlylp62cjZ73AjWWYbxfjkrfF2ONXKdrqPW_Fs9tP9 jtp2p3WjBGo9ILuXr6O0lqUm3WXQL8I3Z5nMVACEQ9aPah1USfGrspw2r6PtmI0zcK3i5u0eTtW '
f = Fernet(_key)
print(f.decrypt(token).decode(utf-8))
