如何在Django中使用web API

from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['GET'])
def my_api_view(request):
    # 处理API请求的逻辑
    data = {'message': 'Hello, World!'}
    return Response(data)

from django.urls import path
from .views import my_api_view

urlpatterns = [
    path('api/my-endpoint/', my_api_view, name='my_api_view'),
]

from rest_framework import serializers

class MyDataSerializer(serializers.Serializer):
    message = serializers.CharField()

# 在API视图中使用序列化器
@api_view(['GET'])
def my_api_view(request):
    data = {'message': 'Hello, World!'}
    serializer = MyDataSerializer(data)
    return Response(serializer.data)

from rest_framework import parsers, renderers

@api_view(['POST'])
def my_api_view(request):
    # 解析请求数据
    data = request.data

    # 处理数据逻辑
    # ...

    # 构建响应数据
    response_data = {'message': 'Success'}

    # 渲染响应数据
    renderer = renderers.JSONRenderer()
    response = renderer.render(response_data)

    return Response(response)
