首先吐槽一个工行的效率问题,兜圈子,回复慢,人家事还多。对接和一堆业务员对接,完全不懂技术,说不到点上。给的账号三番五次是错的,并且文档描述也和实际demo不一致,完全靠百度一点一点磨出来的。
微信小程序只能走微信支付,所以应客户需求走工行渠道的微信支付。

踩坑:一脚一个大坑
1. 如果出现APPID没授权,无效等去找工行,是他们没开权限。
2.文档上写的result_type参数选输,但是这项为空就过不去,在官网上找的和他相关的文档为必输项。
3.给的我请求地址是V2,但是文档上的参考是V1
4.文档上的tran_type是线上线下,业务为线上支付,但是工行就让传线下支付,没有原因。
5.当你完成了工行支付请求,它会响应一个预支付成功,工行业务回复没有预支付这个概念????最后还是预支付成功的。
6.当预支付成功以后,会返回一个sign_data用于唤起微信支付,但是它是base64编码,需解码,解码完之后会有一串内容,用于小程序即可。
7.但是问题来了,小程序API上写的签名类型只有两种,但是工行返回的签名类型是RSA,为此我找了半天转格式,一直签名错误,不用管这些说明,直接拿过来用,signType就是RSA就行。
8.测试网关公钥和线上网关公钥不同,拿着线上网关公钥报 Signature length not correct: got 128 but was expecting 256,工行就是说公钥没问题,最后发现给的是网站的网关公钥,并且生产环境的商户号也没有建档。
