第一步：创建json 序列化工具类：JSONUtil.py

import json
    from django.core.serializers import serialize, deserialize
    from django.db import models
    from django.http import JsonResponse
    
    
    # json 序列化
    def json_to_list(json):
        if json[0] == '[':
            deserializedObjectList = deserialize('json', json)
        else:
            deserializedObjectList = deserialize('json', '[' + json + ']')
        list = []
        for deserializedObject in deserializedObjectList:
            list.append(deserializedObject.object)
        return list
    
    
    # 序列化
    def to_json(obj):
        if isinstance(obj, models.Model):
            obj = [obj]  # 因为serialize只支持可迭代对象，比如querySet对象
        data = serialize("json", obj)
        return data
    
    
    # 该方法没有做严格的验证，只支持dict,models.Model,models.QuerySet，可以根据需要自行扩展
    def render_json(data, dict_key='data', **response_kwargs):
        if isinstance(data, dict):
            return JsonResponse(data)
        data = to_json(data)
        if 'safe' in response_kwargs and response_kwargs['safe'] is False:
            pass
        else:
            data = {dict_key: data}  # 默认必须传递字典数据
        if isinstance(data, str):  # 由于非字典类型的数据会被当做字符串处理，即返回结果两边都有引号，所以此处将其转换为对象，否则ajax调用时不方便处理
            data = json.loads(data)
        return JsonResponse(data, **response_kwargs)

第二步：创建XML 序列化工具类：XMLUtil.py

# -*- coding=utf-8 -*-
    from django.core import serializers
    from django.db import models
    from django.db.models.query import QuerySet
    from django.http import HttpResponse
    
    
    def render_xml(data):
        data = to_xml(data)
        response = HttpResponse(data)
        response['Content-Type'] = 'application/xml'
        return response
    
    
    # 序列化
    def to_xml(data):
        if isinstance(data, models.Model):
            data = [data]  # 因为serialize只支持可迭代对象，比如querySet对象
        elif isinstance(data, QuerySet):
            data = data
        else:
            pass
        data = serializers.serialize("xml", data)
        return data
    
    
    # 反序列化
    def xml_to_list(xml):
        deserializedObjectList = serializers.deserialize("xml", xml)
        list = []
        for deserializedObject in deserializedObjectList:
            list.append(deserializedObject.object)
        return list

视图函数编写：

# json 序列化
    def json(request):
        book_list = Books.objects.all()
        return JSONUtil.render_json(book_list, safe=False)
    
    
    # xml 序列化
    def xml(request):
        book_list = Books.objects.all()
        return XMLUtil.render_xml(book_list)

路由函数：

from django.conf.urls import url
    from . import views
    
    urlpatterns = [
        url('create/', views.create, name='create'),
        url('read', views.read, name='read'),
        url('update/', views.update, name='update'),
        url('delete/', views.delete, name='delete'),
        url('search', views.search, name='search'),
        url('json/', views.json),
        url('xml/', views.xml),
    ]
