写收藏的两种逻辑

.py入mongo：

class Collect(View):

def __init__(self):

self.mongo = Mongodb()

 

def post(self,request):

username = request.POST.get('username')

id = request.POST.get('id')

res = self.mongo.find_one({'username':username})

if res:

my_list = res['id']

my_list.append(int(id))

self.mongo.update_one({'username':username},{'$set':{'id':my_list}})

else:

db_list = [int(id)]

self.mongo.insert({'username':username,'id':db_list})

# return HttpResponse(res)

return HttpResponse('收藏成功')

 

.py入redis:

class Collect(View):

定义添加方法

def post(self,request):

#接收参数

id = request.POST.get('id','未接到参数')

username = request.POST.get('username','未接到参数')

print(f'这里是用户名的id:{username}')

cart_list = cache.get(username,'0')

#如果不存在就创建后添加

if cart_list == '0':

clist = []

clist.append(int(id))

cache.set(username,clist)

else:

cart_list.append(int(id))

cache.set(username,cart_list,360000)

cart_list=cart_list

# print(cart_list)

return HttpResponse('添加成功')

 

 

.html

 

//加入收藏逻辑

            function colle(id){

                username = $.cookie('username');

                alert(username);

                //获取url中的参数

                function getUrlParam(id) {

                var reg = new RegExp("(^|&)" + id + "=([^&]*)(&|$)"); //构造一个含有目标参数的正则表达式对象

                var r = window.location.search.substr(1).match(reg); //匹配目标参数

                if (r != null) return unescape(r[2]); return null; //返回参数值

                }

                var id = getUrlParam('id');

                //删除页面袁术

            

            //请求接口删除库里面的数据

            let param = new URLSearchParams();

            //将参数传递给对象

            param.append('id',id);

            param.append('username',username);

            // param.append('name',name);

            // param.append('price',price);

            

            

                axios({

                        //指定请求地址

                        url:'http://localhost:8000/md_admin_user/colles',

                        //请求参数

                        data:param,

                        //请求类型

                        method:'post',

                        //接口返回值类型

                        responseType:'text',

                })

                .then(function(obj){

            

                            console.log(obj);

                            // alert(obj.data);

                                if(obj.data == '收藏成功'){

                                    // window.location.href = 'http://localhost:8080/user_center_collect.html'

                                    

                                }

                        

                });

     }
