推荐答案

我遇到了此错误，结果是因为我把 SESSION_COOKIE_SECURE = True 在我的主设置文件中，忘记了将 SESSION_COOKIE_SECURE = False 放入我的开发设置中（与OP一样）是在使用 manage.py runserver 时，因此无法使用安全cookie）。

I came across this error, and it turned out to be because I had put SESSION_COOKIE_SECURE = True in my main settings file and forgotten to put SESSION_COOKIE_SECURE = False in my dev settings (as with the OP this was while using manage.py runserver, so secure cookies were not possible).
