當從Facebook登錄使用python-social-auth，SqlAlchemy和Flask重定向時出錯

我正嘗試使用python-social-auth在Flask中實現社交登錄。它在本地主機的開發中工作，但不在生產中。當從Facebook登錄使用python-social-auth，SqlAlchemy和Flask重定向時出錯

從Facebook登錄重定向時發生此錯誤。調試後，它似乎是由sql type pickle或json中的解碼引起的。我鑽進了json模塊，但不知道如何解決它，我認爲它不應該在那裏修復，因爲它是一個內置模塊。

爲什麼Facebook登錄在本地主機上的開發工作，但不是在生產？

只是做骯髒固定在SQLAlchemy的包的sqltype.py調試後。我在下面的方法中發現了不同的價值類型。所以我決定跳過並返回值，如果它已經是字典。

1245  def result_processor(self, dialect, coltype): 
1246   impl_processor = self.impl.result_processor(dialect, coltype) 
1247   loads = self.pickler.loads 
1248   if impl_processor: 
1249    def process(value): 
1250     value = impl_processor(value) 
1251     if value is None: 
1252      return None 
1253     return loads(value) 
1254   else: 
1255    def process(value): 
1256     if value is None: 
1257      return None 
#### ->>>   if type(value) is dict: return value 
1258     return loads(value) 
1259   return process

if type(value) is dict: return value在行1258
