升级到 Django 1.5 获取 UnicodeDecodeError

Question

我正在从 Django 1.3 升级到 1.5 在 1.3 中一切正常，但在 1.5.5 中我遇到了一堆编码错误。查看堆栈：

 Traceback:

 Exception Type: UnicodeDecodeError at /login/
 Exception Value: 'utf8' codec can't decode byte 0xaa in position 0: invalid start byte

Answer 1

我的问题是我设置了

SESSION_SERIALIZER = 'django.contrib.sessions.serializers.JSONSerializer'

在我删除所有编码问题（在正常运行期间，夹具加载仍然无法正常工作）后，我得到了修复。
