对接浦发银行支付（三）-- QR扫码付

本文主要是介绍对接浦发银行支付（三）-- QR扫码付，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、使用场景

扫码付，指的是支付平台，给每个用户的具体订单生成一个QR二维码，用户本人或者他人扫码付款。
付款用户可以直接识别二维码，或者下载到本地，通过微信或支付宝扫一扫识别，第二步将跳转至对应的支付页面H5–第三方支付提供。
二维码其实就是一个h5地址，既要支持微信扫，又要支持支付宝扫。

简单的流程如下：
在这里插入图片描述

从上述要求寻找浦发银行的支付方式，交易类型tranType，选择“OK-聚合动态码支付”。

下面将具体介绍浦发银行的扫码付。

二、扫码付接口

和jsapi支付是同一个接口，交易类型不同，且不必要openId。

接口名称：对公收款支付
接口URI：/api/corporateAccounts/payments/orders
请求方式：POST

请求报文

在这里插入图片描述

terminalNo：终端号，在申请商户的时候，由浦发银行分配给我们
cmdtyDsc：商品描述
tranAmt：交易金额，单位是元
iPAdress：这个最容易踩坑，地址的英文明明是address，它偏偏要少写一个d；其次该字段在Lombok自动生成getter/setter的时候，会变成“IPAdress”。
mrchlInfmAdr：支付回调的异步通知地址
tranType：选择“OK”
mrchId：商户号，在联调接口前，先在浦发后台申请好商户（注意：不是浦发开放平台，这也是我想不明白的地方：既然有开放平台，怎么不把商户后台相关功能一并开放给商户呢？这一点还是微信商户后台做得好，真的是让银行望尘莫及了）
mrchOrdrNo：平台支付流水号，这个字段命名也是醉了（好端端的订单编号OrderNo，被他给取成了OrdrNo，每次都生怕写错了）

响应报文

tranOrdrNo：浦发银行支付流水号，需要保存至支付订单
trandDate：交易日期，本来没什么用，查询支付结果接口中需要用到它，且必传参数。
qRCdLind：二维码链接，这就是我们本文的主要成果，目标就是为了得到它。
