2.3.1.验签数据

商户/代理方用以验证返回的报文是否合法。

值为空字符不参与签名

对返回报文中的返回头rspHeader和返回体rspBody，按照名称的ASCII码从小到大先分别进行排序，如果名称的首字母相同，则比较第二个字母，以此类推。将排序后的rspBody计算Md5(hex转大写)，再将排序后的请求头rspHeader和请求体rspBody计算得到的Md5值进行拼接，拼接后的字符串，返回报文中rspSign签名，使用RSA公钥验签（公钥由易生提供，密钥位数为2048（SHA256WITHRSA）位【其他算法使用其他算法的密钥和加密方式】，计算签名是否正确用以确认易生签发的报文数据。

注意

若rspBody没有返回则算MD5的时候用 {}

rspBody排序后

{"orderNo":"20240524162916","transSequence":"2024052404265933"}

MD5计算排序后的rspBody 并转成大写

排序后rspHeader:

{"easyPayCertificateId":"00000000","rspCode":"000000","rspInfo":"成功","transCode":"0001"}

待验签内容为[verfyString]

{"easyPayCertificateId":"00000000","rspCode":"000000","rspInfo":"成功","transCode":"0001"}121E9DF4157A519349A718EC72A7C477

rspHeader对象排序后的jsonString + MD5(rspBody排序后的verfyString).toUpperCase()
