微信、支付寶二碼合一掃碼支付實現思路（java）

發布時間：2020-09-21 14:07:58 來源：腳本之家閱讀：372 作者：kung900519 欄目：編程語言

一、支付二維碼（預訂單）

根據需要購買的信息創建預訂單，將訂單信息保存到Redis中，并設置有效期，注意生產二維碼的鏈接后的參數可以關聯到Redis中的key；

QRCode 為servlet掃碼請求的URL；

UUIDUtils.getUUID() 為預訂單單號，在servlet請求中截取，然后在Redis中查找對應的Key的數據；

二維碼地址：http://kung900519.qicp.io/interface/QRCode/UUIDUtils.getUUID()；

二、創建二維碼掃碼請求地址servlet：QRCodeServlet；微信支付重定向請求servlet：WechatPayServlet；支付寶重定向請求servlet：AliPayServlet；

QRCodeServlet 用于用戶使用微信或者支付寶掃碼二維碼進行客戶端識別及重定向到對應的業務處理；
