支付宝app支付和h5支付

使用模块 pip install python-alipay-sdk==1.10.1

from alipay import AliPay

    )
    return ali_pay


class AliPayViewSet(viewsets.ViewSet):
    permission_classes = (IsAuthenticated,)
    
    #app支付超简单,返回order_string给前端就ok了

    #h5支付,官方文档https://docs.open.alipay.com/203/105285
    #需要转成form表单
    #如上图所示，用户在商户的H5网站下单支付后，商户系统按照手机网站支付接口alipay.trade.wap.payAPI的参数规范生成订单数据，然后在前端页面通过Form表单的形式请求到支付宝。
