MiddlewareMixin 缺少必需参数：'get_response' django

Question

有谁知道我为什么会收到此错误？我的程序之前可以运行，但我不知道我更改了什么导致它崩溃。

我的主网站可以工作，但每当我向http://10.0.0.233:8000/watcher/form/list发出此获取请求时，都会收到以下错误。我搜索了我的整个项目，没有发现 MiddlewareMixin 在任何地方使用。

网址.py：

from django.urls import path
from . import views

urlpatterns = [
    path('form/list',views.get_all_form_items),
]

视图.py

from django.shortcuts import render
from rest_framework.decorators import api_view
from ast import literal_eval
from rest_framework.response import Response
import json

import sys
sys.path.append("...Utilities") 

from Utilities import string_math

from . models import form_item_db
from . serializers import form_item_db_serializer
@api_view(['GET'])
def get_all_form_items(request):
    snippets = form_item_db.objects.all()
    serializer = form_item_db_serializer(snippets, many=True)
        
    return Response(serializer.data)

错误：

自 10.2020 起，github 上的 DRF 包中有一个修复： https: //github.com/encode/django-rest-framework/commit/7921e9af434f2ccfde6962cf8a1b76331cc77722#diff-25717930a68aebbdb51ee5f4060fb1e756d65ee4e8d96faf8 ad614ceced0db05

rest_framework/authentication.py 第 139 行附近

check = CSRFCheck()

更改为

def dummy_get_response(request):  # pragma: no cover
    return None

check = CSRFCheck(dummy_get_response)
