十二、支付宝沙箱环境配置
12.1.创建应用
进入蚂蚁金服开放平台（https://open.alipay.com/platform/home.htm），登录后进入管理中心-->>应用列表
创建应用
创建应用后会有一个appid。还需要提交信息进行审核。微信支付和支付宝支付都是要求企业认证才可以完成的，个人开发不可以，所以我们需要用
沙箱环境，它可以让我们不具备这些应用或者说应用审核还没通过的时候先开发调试
12.2.沙箱环境
沙箱应用地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info
（1）公钥和私钥的生成方法
地址：https://docs.open.alipay.com/291/105971/
选winwods，如果linux就选linux
下载好工具照着生成就可以了
（2） 把生成的公钥和私钥拷贝到trade/keys下面--->>>重命名--->>首位各添加下面的内容
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
（3）把支付宝公钥也拷贝到这路径下面，同样首尾添加
12.3.文档说明
我们主要用到电脑网站支付，文档地址：https://docs.open.alipay.com/270
用到的API接口：统一收单下单并支付页面接口
里面有文档说明
几个比较重要的参数
sign签名
应该看未使用开放平台的SDK里面的说明：https://docs.open.alipay.com/291/106118
请求参数
必填的几个：
12.4.编写代码
把环境改成本地的
首先的安装一个模块
pip install pycryptodome
utils中新建alipay.py，代码如下：

（1）配置url
# 配置支付宝支付相关接口的url
path('alipay/return/', AlipayView.as_view())

（6）测试代码
把本地修改的地方一定要上传到服务器，因为我们需要在服务器上调试代码
vue项目中api.js里面local_host改为服务器ip
let local_host = 'http://47.93.198.159:8000';
在phcharm中开始运行项目
浏览器访问地址：http://47.93.198.159:8000/orders/
创建一个订单
生成订单的详情
12.6.vue静态文件放到django中
vue有两种开发模式
- build 用来生成静态文件
- dev
（1）运行
cnpm run build
生成的静态文件在dist目录下面
（2）把index.html拷贝到templates目录下
（3）django中创建static目录
- 把index.entry.js考到django的static目录下面
- 把dist/static下的两个文件夹拷贝到django static目录下
（4）settings设置静态文件路径
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static"),
)
（5）修改index.html中静态文件路径
<script type="text/javascript" src="/static/index.entry.js"></script></body>
（6）配置index的url
from django.views.generic import TemplateView
urlpatterns = [
# 首页
path('index/', TemplateView.as_view(template_name='index.html'),name='index')
]
（7）配置支付成功return的地址

response = redirect("/index/#/app/home/member/order")
return response
else:
response = redirect("index")
return response
