Django实现支付宝沙箱操作，太强了呀！

Django实现支付宝沙箱操作

环境即所需模块

1. Django == 3.1.0
2. python == 3.7.4
3. python-alipay-sdk=2.0.1

所需

1. 下载模块 python-alipay-sdk=2.0.1
2. 文档 非官方支付宝 Python SDK: https://github.com/fzlee/alipay/blob/master/README.zh-hans.md#alipay.trade.page.pay

沙箱环境配置

 

1. 在支付宝开放平台---->开发者中心—>开发服务---->沙箱
2. RSA2密钥生成并上传 参考官方地址：https://opendocs.alipay.com/open/291/105971
3. 下载支付宝开放平台开发助手下载地址https://opendocs.alipay.com/open/291/introduce下载后生成秘钥[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-iAJ4s57z-1602600230093)(C:\Users\ASUS\AppData\Roaming\Typora\typora-user-images\image-20201013215751437.png)]

Django Models

# 支付状态表
class Status(BaseModel):
    name = models.CharField(max_length=32)

    class Meta:
        db_table = 'status'


# 支付表
class Order(BaseModel):
    out_trade_no = models.CharField(max_length=60)
    trada_no = models.CharField(max_length=60, null=True, blank=True)
    goods = models.ForeignKey(Goods, on_delete=models.CASCADE)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    goods_num = models.IntegerField()
    status = models.ForeignKey(Status, on_delete=models.CASCADE)

    class Meta:
        db_table = 'order'

Django Views配置

1. ​ 所需的包import uuid import redis from app01.views import login_serializer from alipay import AliPay, AliPayConfig123

# 绝对路径打开文件  {}代表从这里往前
app_private_key_string = open('{}\\app02\\alipay_key\\app_private_key'.format(settings.BASE_DIR)).read()
alipay_public_key_string = open('{}\\app02\\alipay_key\\alipay_public'.format(settings.BASE_DIR)).read()12
