Django Web 應用程序處理發布請求

Question

我是 Django 的新手，對處理對我的服務器的 post 請求感到困惑。 我想接受這種 json 格式的 post 請求： {“username”:”john@doe.com”,”password”:”pass@word1”}並用這些 json 格式的回復回復：

{“status”:”success”,”message”:”user_authed”}如果找到用戶和密碼組合{“status”:”failure”,”message”:”user_not_found”}如果用戶和密碼組合未找到成立

這是我的 views.py 代碼

from django.shortcuts import render

from django.http import HttpResponse
from django.shortcuts import get_object_or_404
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from . models import users
from . serializers import userSerializer


class userList(APIView):

def get(self, request):
    user = users.objects.all()
    serializer = userSerializer(user, many=True)
    return Response(serializer.data)

def post(self, request):
    serializer = userSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

我想知道如何格式化 post 函數以接受上述格式的請求，以及如何自定義回復是否通過身份驗證。 任何幫助將不勝感激

您嘗試完成的操作稱為身份驗證。 請提前閱讀https://www.django-rest-framework.org/api-guide/authentication/ 。

然后根據所學內容編輯您的問題。

#serializers.py
from rest_framework import serializers
UserRequestSerializer(serializers.Serializer)
    username = CharField(required=True, max_length=128)
    password = CharField(required=True, max_length=128)

#views.py
from .serializers import *

UserCheckView(APIView):

    def post(request, *args, **kwargs):
        serializer = UserRequestSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        try:
            user = User.objects.get(username=serializer.validated_data['username'])
            if user.check_password(serializer.validated_data['password']:
                return Response(data={“status”:”success”,”message”:”user_authed”},status=status.HTTP_200_OK)
            return Response(data={“status”:”failure”,”message”:”password_did_not_match”}, status=status.HTTP_400_BAD_REQUEST)
        except User.DoesNotExist:
            return Response(data={“status”:”failure”,”message”:”user_not_found”}, status=status.HTTP_404_NOT_FOUND)
