支付寶提供接口:給商戶使用,收錢

-Java,php,C#的demo,沒有python的demo -git有人封裝了 -需要安裝模塊:pip3 install -應用私鑰---自己保存,一定不能丟 -應用公鑰---給別人用 -支付寶公鑰---支付寶用的 -生成公鑰私鑰:https://docs.open.alipay.com/291/105971 -把應用公鑰配置在支付寶上:應用公鑰,配置完成以后,支付寶自動生成一個支付寶公鑰 -在程序中:配置應用私鑰,支付寶公鑰 -如果支付成功,支付寶會回調(diào),但是如果你的服務器掛掉了怎么辦? -支付寶24小時以內(nèi)不定時再給你發(fā),你修改掉訂單狀態(tài)即可 -支付成功,支付寶會有一個get回調(diào),一個post回調(diào):修改訂單狀態(tài)
