创建表

	python manage.py makemigrations

	python manage.py migrate

参考官方文档

定义序列化器

在 lyb 文件夹下创建 serializers.py 文件，

	from rest_framework import serializers
	from .models import Lyb


	class LybSerializer(serializers.HyperlinkedModelSerializer):
	class Meta:
	model = Lyb # 需要序列化的模型
	fields = "__all__" # 序列化所有字段

在 lyb 的 view.py 文件下创建视图

	from django.shortcuts import render
	from rest_framework import viewsets
	from .models import Lyb
	from .serializers import LybSerializer
	from django.shortcuts import HttpResponse

	# Create your views here.

	class LybViewSet(viewsets.ModelViewSet):
	"""
	API endpoint that allows users to be viewed or edited.
	"""
	queryset = Lyb.objects.all().order_by('-posttime')
	serializer_class = LybSerializer

配置跨域

https://blog.csdn.net/zbx2010/article/details/107481686

参考到上面的第一点就行了

在 setting.py 中

	INSTALLED_APPS = [
	...
	'corsheaders',
	...
	]

	MIDDLEWARE = [
	'corsheaders.middleware.CorsMiddleware', # 放最前面
	...
	]

CORS_ORIGIN_ALLOW_ALL: 添加允许执行跨站点请求的主机

	# 如果为 True，则将不使用白名单，并且将接受所有来源。默认为 False
	CORS_ORIGIN_ALLOW_ALL = True
