luffy课程表的创建-支付宝API-购买服务器

# 1、在沙箱环境下实名认证：https://openhome.alipay.com/platform/appDaily.htm?tab=info

# 2、电脑网站支付API：https://docs.open.alipay.com/270/105898/

# 3、完成RSA密钥生成：https://docs.open.alipay.com/291/105971

# 4、在开发中心的沙箱应用下设置应用公钥：填入生成的公钥文件中的内容

# 5、Python支付宝开源框架：https://github.com/fzlee/alipay

给定支付宝功能，例如alipay.trade.page.pay，我们将定义一个相应的功能alipay.api_alipay_trade_page_pay()

通常我们会进行这样的翻译：

function_name = "api_" + alipay_function_name.replace(".", "_")
根据支付宝文件，输入的某些参数biz_content是可选的，而有些则不是。我们以这种方式定义函数，以便您可以将这些可选参数放入kwargs：

def api_alipay_xxx(self, out_trade, total_amount, **kwargs):
    ...
    biz_content.update(kwargs)

＃对于Python 2用户（您应该真正考虑Python 3），
＃确保非ascii字符串是utf-8编码的 
subject =  u “测试订单” .encode（ “ utf8 ”）
＃对于Python 3用户，只需使用默认字符串 
主题 =  “测试订单”

＃通过网络付款，在浏览器中打开以下URL：https://openapi.alipay.com/gateway.do？+ order_string 
order_string = alipay.api_alipay_trade_page_pay（
     out_trade_no = “ 20161112 ”，

     return_url = “ https://example.com ”，
     notify_url = “ https://example.com/notify ”  ＃这是可选

＃通过WAP付款，在浏览器中打开以下网址：https://openapi.alipay.com/gateway.do？+ order_string 
order_string = alipay.api_alipay_trade_wap_pay（
