python之Django 'AsgiRequest' 对象没有属性 'content_type'

2024年10月01日34lori

我正在开发一个名为 app 的 django 应用程序，它是 django 项目的一部分，但我在尝试登录管理员时遇到了一些问题。

当我尝试通过 localhost:8000/admin/login/登录在 shell 中创建的 super 用户时出现错误，它显示错误:

然后显示回溯

这是我的requirements.txt:

appdirs==1.4.2 
Django==1.10.5 
django-custom-user==0.7 
packaging==16.8 
psycopg2==2.6.2 
pyparsing==2.1.10 
six==1.10.0 
Pillow==4.0.0 
asgi-redis==0.8.3 
asgiref==0.9 
autobahn==0.12.1 
channels==0.9.3 
daphne==0.9.1 
haikunator==1.0.1 
msgpack-python==0.4.7

six==1.10.0 
Twisted==15.5.0 
txaio==2.2.1 
wheel==0.24.0 
zope.interface==4.1.3

有什么好的方法可以解决这个问题吗？ 最难得的是，直到昨天它都能正常工作，而今天我没有做任何更改而且它不起作用

请您参考如下方法:

AsgiRequest 来自 channels 包。因此，要么将其升级到最新版本，要么安装您正在使用的 channels 版本支持的 django 版本。因此，请尝试使用 pip install channels -U 将 channel 升级到最新版本以解决此问题。
