python - /social/complete/facebook/ 处的 social_django TypeError 需要一个类似字节的对象，而不是“元组”

问题描述

我正在使用 social_django 进行 Facebook 登录。当用户使用 facebook 登录时，我想拥有 facebook 的个人资料照片。但是，当我尝试使用 facebook 登录时出现此错误；

/social/complete/facebook/a 字节类对象的类型错误是必需的，而不是“元组”

我已经设法将图片（Facebook 给我的 url 作为回应）下载到我的 media/profile_pics 文件夹，但我无法将它保存到该人的个人资料图片中。我认为问题来自 ImageField 和 FileField 困境，但我无法解决。

我在网上尝试了许多解决方案，但没有帮助。感谢您在高级方面的任何帮助。
