     ----  一切皆是资源,操作只是请求方式
     
     ----book表增删改查

restful协议理解

安装restframework

pip3 install djangorestframework 

Django序列化方式
# 方式1：
        # publish_list=list(Publish.objects.all().values("name","email"))

        # 方式2：
        # from django.forms.models import model_to_dict
        # publish_list=Publish.objects.all()
        # temp=[]
        # for obj in publish_list:
        #     temp.append(model_to_dict(obj))

        # 方式3：
        # from django.core import serializers
        # ret=serializers.serialize("json",publish_list)
