luffcc项目-13-积分抵扣、发起支付、

一、积分抵扣

1.修改用户模型

user/models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.
from lyapi.utils.models import BaseModelclass User(AbstractUser):phone = models.CharField(max_length=16,null=True,blank=True)wechat = models.CharField(max_length=16,null=True,blank=True)credit = models.IntegerField(default=0, blank=True, verbose_name="贝里")class Meta:db_table = 'ly_user'verbose_name = '用户表'verbose_name_plural = verbose_nameclass Credit(BaseModel):"""积分流水"""OPERA_OPION = ((1, "赚取"),(2, "消费"),)user = models.ForeignKey("User", related_name="user_credit", on_delete=models.CASCADE, verbose_name="用户")opera = models.SmallIntegerField(choices=OPERA_OPION,verbose_name="操作类型")number = models.SmallIntegerField(default=0, verbose_name="积分数值")class Meta:db_table = 'ly_credit'verbose_name = '积分流水'verbose_name_plural = verbose_namedef __str__(self):return "%s %s %s 贝壳" % ( self.user.username, self.OPERA_OPION[self.opera][1], self.number )from course.models import Course
class UserCourse(BaseModel):"""用户的课程购买记录"""pay_choices = ((1, '用户购买'),(2, '免费活动'),(3, '活动赠品'),(4, '系统赠送'),)# 1   1# 1   2# 1   3# 2   1# 2   2user = models.ForeignKey(User, related_name='user_courses', on_delete=models.DO_NOTHING, verbose_name="用户")course = models.ForeignKey(Course, related_name='course_users', on_delete=models.DO_NOTHING, verbose_name="课程")trade_no = models.CharField(max_length=128, null=True, blank=True, verbose_name="支付平台的流水号", help_text="将来依靠流水号到支付平台查账单")buy_type = models.SmallIntegerField(choices=pay_choices, default=1, verbose_name="购买方式")pay_time = models.DateTimeField(null=True, blank=True, verbose_name="购买时间")out_time = models.DateTimeField(null=True, blank=True, verbose_name="过期时间") #null表示永不过期class Meta:db_table = 'ly_user_course'verbose_name = '课程购买记录'verbose_name_plural = verbose_name

数据迁移

python manage.py makemigrations
python manage.py migrate

在xadmin运营站点中,给当前测试用户设置积分

2.设置积分比例

在配置文件中,设置积分和真实货币的换算比例
settings/contains.py增加配置:

# 积分兑换比例
CREDIT_MONEY = 10   # 10个积分顶一块钱

3.增加返回积分和换算比例的字段

在用户登录的代码中,增加返回积分和换算比例的字段

服务端中users/utils.py,代码;

...
from lyapi.settings import containsdef jwt_response_payload_handler(token, user=None, request=None):# print('>>>>>',user,type(user))return {'token': token,'username': user.username,'id':user.id,'credit':user.credit,'credit_to_money':contains.CREDIT_MONEY,}
...

在客户端中,保存积分到本地存储中.
Login.vue,在登录成功以后的代码中,

...loginHandle(){// 登录，用户名、密码、验证码数据var captcha1 = new TencentCaptcha('2041284967', (res) =>{ //生成图片验证码的if (res.ret === 0){console.log(res.randstr);console.log(res.ticket);this.$axios.post(`${this.$settings.Host}/users/login/`,{username:this.username,password:this.password,ticket:res.ticket,randstr:res.randstr,}).then((res)=>{console.log(res);// console.log(this.remember);if (this.remember){localStorage.token = res.data.token;localStorage.username = res.data.username;localStorage.id = res.data.id;localStorage.credit = res.data.credit;localStorage.credit_to_money = res.data.credit_to_money;sessionStorage.removeItem('token');sessionStorage.removeItem('username');sessionStorage.removeItem('id');sessionStorage.removeItem('credit');sessionStorage.removeItem('credit_to_money');}else {sessionStorage.token = res.data.token;sessionStorage.username = res.data.username;sessionStorage.id = res.data.id;sessionStorage.credit = res.data.credit;sessionStorage.credit_to_money = res.data.credit_to_money;localStorage.removeItem('token');localStorage.removeItem('username');localStorage.removeItem('id');localStorage.removeItem('credit');localStorage.removeItem('credit_to_money');}this.$confirm('下一步想去哪消费！', '提示', {confirmButtonText: '去首页',cancelButtonText: '回到上一页',type: 'success'}).then(() => {this.$router.push('/');}).catch(() => {this.$router.go(-1);});}).catch((error)=>{this.$alert('用户名或者密码错误', '登录失败', {confirmButtonText: '确定',});})}});captcha1.show(); // 显示验证码}
...

4.用户可以设置抵扣积分

在用户购买课程进入计算页面时把积分显示并让用户可以设置要抵扣的积分金额

Orde.vue

<template><div class="cart"><Vheader/><div class="cart-info"><h3 class="cart-top">购物车结算 <span>共1门课程</span></h3><div class="cart-title"><el-row><el-col :span="2">&nbsp;</el-col><el-col :span="10">课程</el-col><el-col :span="8">有效期</el-col><el-col :span="4">价格</el-col></el-row></div><div class="cart-item" v-for="(course,index) in course_list"><el-row><el-col :span="2" class="checkbox">&nbsp;&nbsp;</el-col><el-col :span="10" class="course-info"><img :src="course.course_img" alt=""><span>{{course.name}}</span></el-col><el-col :span="8"><span>{{course.expire_text}}</span></el-col><el-col :span="4" class="course-price">¥{{course.real_price}}</el-col></el-row></div><div class="discount"><div id="accordion"><div class="coupon-box"><div class="icon-box"><span class="select-coupon">使用优惠劵：</span><a class="select-icon unselect" :class="use_coupon?'is_selected':''" @click="use_coupon=!use_coupon"><img class="sign is_show_select" src="../../static/img/12.png" alt=""></a><span class="coupon-num">有{{coupon_list.length}}张可用</span></div><p class="sum-price-wrap">商品总金额：<span class="sum-price">0.00元</span></p></div><div id="collapseOne" v-if="use_coupon"><ul class="coupon-list"  v-if="coupon_list.length>0"><li class="coupon-item" :class="select_coupon(index,coupon.id)" v-for="(coupon,index) in coupon_list" @click="change_coupon(index,coupon.id)"><p class="coupon-name">{{coupon.coupon.name}}</p><p class="coupon-condition">满{{coupon.coupon.condition}}元可以使用</p><p class="coupon-time start_time">开始时间：{{coupon.start_time.replace('T',' ')}}</p><p class="coupon-time end_time">过期时间：{{coupon.end_time.replace('T',' ')}}</p></li></ul><div class="no-coupon" v-if="coupon_list.length<1"><span class="no-coupon-tips">暂无可用优惠券</span></div></div></div><div class="credit-box"><label class="my_el_check_box"><el-checkbox class="my_el_checkbox" v-model="use_credit"></el-checkbox></label><p class="discount-num1" v-if="!use_credit">使用我的贝里</p><p class="discount-num2" v-else><span>总积分：{{credit}}，<el-input-number v-model="num" @change="handleChange" :min="0" :max="max_credit()" label="描述文字"></el-input-number>，已抵扣 ￥{{num / credit_to_money}}，本次花费{{num}}积分</span></p></div><p class="sun-coupon-num">优惠券抵扣：<span>0.00元</span></p></div><div class="calc"><el-row class="pay-row"><el-col :span="4" class="pay-col"><span class="pay-text">支付方式：</span></el-col><el-col :span="8"><span class="alipay"  v-if="pay_type===0"><img src="../../static/img/alipay2.png"  alt=""></span><span class="alipay" @click="pay_type=0"  v-else><img src="../../static/img/alipay.png" alt=""></span><span class="alipay wechat" v-if="pay_type===1"><img src="../../static/img/wechat2.png" alt="" ></span><span class="alipay wechat"  @click="pay_type=1" v-else><img src="../../static/img/wechat.png" alt=""></span></el-col><el-col :span="8" class="count">实付款： <span>¥{{ (total_price - num/credit_to_money).toFixed(2)}}</span></el-col><el-col :span="4" class="cart-pay"><span @click="payhander">支付</span></el-col></el-row></div></div><Footer/></div>

5.后端抵扣积分接口

在用户确定确认下单时, 在序列化器中计算实付金额时纳入积分抵扣
order/serializers.py

import datetimefrom rest_framework import serializers
from . import models
from django_redis import get_redis_connection
from users.models import User
from course.models import Course
from course.models import CourseExpire
from coupon.models import UserCoupon, Coupon

二、发起支付

支付宝开发平台
https://open.alipay.com/platform/home.htm

1.沙箱环境

是支付宝提供给开发者的模拟支付的环境
沙箱环境跟真实环境是分开的，项目上线时必须切换对应的配置服务器地址和开发者ID和密钥。

沙箱账号：https://openhome.alipay.com/platform/appDaily.htm?tab=account

  真实的支付宝网关:   https://openapi.alipay.com/gateway.do沙箱的支付宝网关:   https://openapi.alipaydev.com/gateway.do

2.支付宝开发者文档

文档主页：https://openhome.alipay.com/developmentDocument.htm
产品介绍：https://docs.open.alipay.com/270

3.开发支付功能

cd lyapi/apps
python ../../manage.py startapp payment

注册子应用

INSTALLED_APPS = [...'payment',
]

4.配置秘钥

(1)生成应用的私钥和公钥

下载对应系统的秘钥生成工具: https://doc.open.alipay.com/docs/doc.htm?treeId=291&articleId=105971&docType=1

windows操作系统

生成如下,安装软件时需要管理员身份来安装.

Linux系统

生成如下:

openssl
OpenSSL> genrsa -out app_private_key.pem 2048                         # 生成私钥到指定文件中
OpenSSL> rsa -in app_private_key.pem -pubout -out app_public_key.pem  # 导出公钥
OpenSSL> exit

把软件生成的应用公钥复制粘贴到支付宝网站页面中.
点击修改以后,粘贴进去生成支付宝公钥。

(2)保存应用私钥文件

在payment应用中新建keys目录，用来保存秘钥文件。
将应用私钥文件app_private_key.pem复制到payment/keys目录下。
windows系统生成的私钥必须在上下两行加上以下标识:

-----BEGIN RSA PRIVATE KEY-----
私钥
-----END RSA PRIVATE KEY-----

(3)保存支付宝公钥到项目中

在payment/key目录下新建alipay_public_key.pem文件，用于保存支付宝的公钥文件。
将支付宝的公钥内容复制到alipay_public_key.pem文件中

-----BEGIN PUBLIC KEY-----
公钥
-----END PUBLIC KEY-----

(4)使用支付宝的sdk开发支付接口

SDK：https://docs.open.alipay.com/270/106291/
python版本的支付宝SDK文档：https://github.com/fzlee/alipay/blob/master/README.zh-hans.md
安装命令：

pip install python-alipay-sdk --upgrade

5.后端提供发起支付的接口url地址

总urls.py

...path(r'payment/',include('payment.urls')),
...

payment/urls.py

from django.urls import path,re_path
from . import viewsurlpatterns = [path('alipay/',views.AlipayView.as_view(),),path('result/',views.AlipayResultView.as_view(),)]

payment/views.py
