AliPay
- 阿里的支付也就是支付宝，官网已经出了Python的SDK了，所以先下载：pip3 install alipay-sdk-python 网址
- 支付宝沙箱环境的地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info
一、使用详情：
第1步:访问沙箱环境地址，注册一个商家账户点击
- 密钥生成方式1(推荐)：生成RSA密钥
- 密钥生成方式2：OpenSSL工具生成密钥
- 按照上面方式生成商户的公钥和私钥，把公钥放入网站私钥自己留着签名用,设置应用公钥后
- 下面是商户信息以及卖家信息下载一个支付宝的沙箱环境
- 然后按照下面的账号和密码登录和支付，只支持安卓
第2步:阅读文档 找到一个适合自己的API 点击
- 这里选择：统一收单下单并支付页面接口 点击
- 仔细阅读文档按照文档的参数要求去向接口发请求
第3步:代码实例
- 回调url的测试要放在公网IP上,所以测试的时候放入自己服务器 pip install alipay-sdk-python
- alipay-sdk-python
