08支付和订单
为了方便开发，和以后项目的维护，我们再次创建子应用orders来完成接下来的订单和订单支付功能。
cd luffy/apps
python ../../manage.py startapp orders注册子应用，settings/dev.py，代码：

return Response({"message":"成功生成订单!","order":order.order_number})上面我们使用了redis的事务操作保证数据的一致性。但是mysql里面我们也是在进行多表操作，所以也是需要使用事务来保证数据的一致性的。
事务有四大特性：
原子性（Atomicity）
一致性（Consistency）
隔离性（Isolation）[事务隔离级别->幻读，脏读]
持久性（Durability）django框架本身就提供了2种事务操作的用法。
django的事务操作方法主要通过 django.db.transation模块完成的。
启用事务用法1：
from django.db import transaction
from rest_framework.views import APIView
class OrderAPIView(APIView):
@transaction.atomic # 开启事务，当方法执行完成以后，自动提交事务
def post(self,request):
....启用事务用法2：
from django.db import transaction
from rest_framework.views import APIView
class OrderAPIView(APIView):
def post(self,request):
....
with transation.atomic(): # 开启事务，当with语句执行完成以后，自动提交事务
# 数据库操作在使用事务过程中， 有时候会出现异常，当出现异常的时候，我们需要让程序停止下来，同时需要回滚事务。
from django.db import transaction
from rest_framework.views import APIView
class OrderAPIView(APIView):
def post(self,request):
....
with transation.atomic():
# 设置事务回滚的标记点
sid = transation.savepoint()
....
try:
....
except:
transation.savepoint_rallback(sid)使用django提供的mysql事务操作保证下单过程中的数据一致性

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。

]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
应用公钥复制粘贴到支付宝网站页面中.
/assets/1554192122648.png)
点击修改以后,粘贴进去
2. 保存应用私钥文件
在payments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。
-----BEGIN RSA PRIVATE KEY-----
私钥
-----END RSA PRIVATE KEY-----3. 保存支付宝公钥
在payment/keys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/

订单状态显示分析
根据订单状态显示:
1. 如果未支付[order.order_stauts=0],则显示"去支付"按钮
2. 如果已支付[order.order_stauts=1],则显示"去学习"按钮
3. 如果未支付,并超过指定时间[12个小时],则显示"已取消" [celery+RabbitMQ / Django-crontab 定时任务 ]
用户下单在12小时以后自动判断订单状态如果是0,则直接改成3
