1.文件存储

视频文件,存储到某个位置,如果放在自己服务器上
	放在项目的media文件夹
    服务器上线后,用户既要访问接口,又要看视频,都是一个域名和端口
    分开:文件单独放在文件服务器上,文件服务器带宽很高
文件服务器:专门存储文件的服务器
	第三方:
    	阿里云:对象存储 oss
        腾讯对象存储
        七牛云存储
	自己搭建:
    	fastdfs:文件对象存储  https://zhuanlan.zhihu.com/p/372286804
        minio:
python 如何把文件传到上面
	对应sdk
七牛云存储 
	使用代码,上传视频
    两种方案
    	前端---》传到咱们的服务器----》在服务端再传入到七牛云

七牛云上传文件

from qiniu import Auth,put_file

q = Auth('','')
# 要上传的空间
bucket_name = 'lqz'
# 上传后保存的文件名
key = '致命诱惑.mp4'
# 生成上传 Token,可以指定过期时间等
token = q.upload_token(bucket_name, key, 3600)
# 要上传文件的本地路径
localfile = './致命诱惑.mp4'
ret, info = put_file(token, key, localfile, version='v2')
print(info)

2.搜索导航栏

前端  Header 组件上有个搜索框----》输入内容,搜索----》后端搜索接口
所有的商城类的网站,app,都会有搜索功能,其实搜索功能非常复杂且技术含量高
	咱们目前只是简单的搜索,输入课程名字,价格 就可以把实战课搜出来
    输入:课程名字,价格把所有类型课程都搜出来(查询多个表)
    后面会有专门的搜索引擎:分布式全文检索引擎 es  做专门的搜索
前端搜索结果呈现页面

#### 路由
router.register('search', views.SearchCourseView, 'search')

#### 视图类
class SearchCourseView(GenericViewSet, CommonListModelMixin):
    # 只有实战课
    queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
    serializer_class = CourseSerializer

5.支付宝支付介绍

立即购买功能,点击立即购买按钮,使用支付宝支付
支付宝支付
	测试环境:大家都可以测试
    	https://openhome.alipay.com/develop/sandbox/app
    正式环境:申请,有营业执照
    	咱们做不了
咱们开发虽然用的沙箱环境,后期上线,公司会自己注册,注册成功后有个商户id号,作为开发,只要有商户id好,其他步骤都是一样,所有无论开发还是测试,代码都一样,只是商户号不一样
支付流程
使用支付宝支付
	API接口
    SDK:优先使用,早期,支付宝没有python的sdk,后期有了
    使用了第三方sdk
    	第三方人通过api接口,使用python封装了sdk,开源出来了
沙箱环境
	安卓的支付宝app,付款用的---》买家用的
    扫码使用这个app,付款,这个app的钱都是假的,付款进测试商户(卖家)

支付测试,生成支付链接

https://github.com/fzlee/alipay
安装
pip install python-alipay-sdk
生成公钥私钥---》非对称加密
	使用支付宝提供的工具:https://opendocs.alipay.com/common/02kipl
    就可以生成公钥私钥
    
    生成的公钥---》配置在支付宝的网站上(沙箱环境)---》生成一个支付宝公钥---》以后使用这个支付宝公钥
支付宝公钥,应用私钥---》放到项目中
	pub.pem
	pri.pem
代码
from alipay import AliPay
from alipay.utils import AliPayConfig
app_private_key_string = open("./pri.pem").read()
alipay_public_key_string = open("./pub.pem").read()
alipay = AliPay(
    appid="2016092000554611",
    app_notify_url=None,  # 默认回调 url
    app_private_key_string=app_private_key_string,
    # 支付宝的公钥,验证支付宝回传消息使用,不是你自己的公钥,
    alipay_public_key_string=alipay_public_key_string,
    sign_type="RSA2",  # RSA 或者 RSA2
    debug=False,  # 默认 False
    verbose=False,  # 输出调试数据
    config=AliPayConfig(timeout=15)  # 可选,请求超时时间
)
res=alipay.api_alipay_trade_page_pay(subject='性感内衣', out_trade_no='asdas23sddfsasf', total_amount='999')
print('https://openapi.alipaydev.com/gateway.do?'+res)

7.订单表设计

订单板块需要写的接口
	下单接口---》没有支付是订单是待支付状态
    支付宝post回调接口---》修改订单状态成已支付
    前端get回调接口(暂时先不关注)
订单板块表设计
	订单表
    订单详情表
新建order 的app,在models.py中写入表
from django.db import models

from django.db import models
from user.models import User
from course.models import Course


class Order(models.Model):
    """订单模型"""
    status_choices = (
        (0, '未支付'),
        (1, '已支付'),
        (2, '已取消'),
        (3, '超时取消'),
    )
    pay_choices = (
        (1, '支付宝'),
        (2, '微信支付'),
    )
    订单标题
    subject = models.CharField(max_length=150, verbose_name="订单标题")
    # 订单总价格
    total_amount = models.DecimalField(max_digits=10, decimal_places=2, verbose_name="订单总价", default=0)
    # 订单号,咱们后端生成的,唯一:后期支付宝回调回来的数据会带着这个订单号,根据这个订单号修改订单状态
    # 使用什么生成? uuid(可能重复,概率很多)    【分布式id的生成】  雪花算法
    out_trade_no = models.CharField(max_length=64, verbose_name="订单号", unique=True)
    # 流水号:支付宝生成的,回调回来,会带着
    trade_no = models.CharField(max_length=64, null=True, verbose_name="流水号")
    # 订单状态
    order_status = models.SmallIntegerField(choices=status_choices, default=0, verbose_name="订单状态")
    # 支付类型,目前只有支付宝
    pay_type = models.SmallIntegerField(choices=pay_choices, default=1, verbose_name="支付方式")
    # 支付时间---》支付宝回调回来,会带着
    pay_time = models.DateTimeField(null=True, verbose_name="支付时间")
    # 跟用户一对多    models.DO_NOTHING
    user = models.ForeignKey(User, related_name='order_user', on_delete=models.DO_NOTHING, db_constraint=False,
                             verbose_name="下单用户")
    created_time = models.DateTimeField(auto_now_add=True, verbose_name='创建时间')

    class Meta:
        db_table = "luffy_order"
        verbose_name = "订单记录"
        verbose_name_plural = "订单记录"

    def __str__(self):
        return "%s - ¥%s" % (self.subject, self.total_amount)


class OrderDetail(models.Model):
    """订单详情"""
    # related_name 反向查询替换表名小写_set
    # on_delete 级联删除
    # db_constraint=False ----》默认是True,会在表中为Order何OrderDetail创建外键约束
    # db_constraint=False  没有外键约束,插入数据 速度快,  可能会产生脏数据【不合理】,所以咱们要用程序控制,以后公司惯用的
    # 对到数据库上,它是不建立外键,基于对象的跨表查,基于连表的查询,继续用,跟之前没有任何区别
    order = models.ForeignKey(Order, related_name='order_courses', on_delete=models.CASCADE, db_constraint=False,
                              verbose_name="订单")
    course = models.ForeignKey(Course, related_name='course_orders', on_delete=models.DO_NOTHING, db_constraint=False,
                               verbose_name="课程")
    price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="课程原价")
    real_price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="课程实价")

    class Meta:
        db_table = "luffy_order_detail"
        verbose_name = "订单详情"
        verbose_name_plural = "订单详情"

    def __str__(self):
        try:
            return "%s的订单:%s" % (self.course.name, self.order.out_trade_no)
        except:
            return super().__str__()
'''
ForeignKey 中on_delete 
    -CASCADE  级联删除
    -DO_NOTHING    啥都不做,没有外键约束才能用它
    -SET_NULL       字段置为空,字段 null=True
    -SET_DEFAULT   设置为默认值,default='xx'
    -PROTECT    受保护的,很少用
    -models.SET(函数内存地址)   会设置成set内的值
'''

8.下单接口

登录后才能用---》前端点击立即购买----》post--》携带数据  {courses:[1,],total_amount:99.9,subject:'xx课程'}----》视图类中重写create方法---》主要逻辑写到序列化类中
主要逻辑:
	1.取出所有课程id号,拿到课程
    2.统计总价格,跟传入的total_amount做比较,如果一样,继续往后
    3.获取购买人信息:登录后才能访问的接口 request.user
    4.生成订单号 支付链接需要,存订单表需要
    5.生成支付链接:支付宝支付生成,    
    6.生成订单记录,订单是待支付状态(order,order_detail)
    7.返回前端支付链接

序列化类
