encStr计算方式

将提交body的json(URL编码前的内容)例： {"phoneNumber":"K+s7qzwjiqPumZu8DpmV9sJv630oWnJiFc9alzSZxLoKGyk5wbQVY/rzbrfguwstWW3h03PvYxm71jg8+4RLq5ih5PINR5a8GkCgtyPCA18KwafW33A1ff3YqmrCRaWjCsPg2PZ8IE4eDH53Upz1dZ/DX6wmQr9mKcksMHiO5Kg=","source":"3","t":"1679032038779","encStr":""}

依次拼接所有属性值 注：排除所有空值,包括t值,encStr因为没有置入所以也是排除的

拼接后结果： 假设定义s值 K+s7qzwjiqPumZu8DpmV9sJv630oWnJiFc9alzSZxLoKGyk5wbQVY/rzbrfguwstWW3h03PvYxm71jg8+4RLq5ih5PINR5a8GkCgtyPCA18KwafW33A1ff3YqmrCRaWjCsPg2PZ8IE4eDH53Upz1dZ/DX6wmQr9mKcksMHiO5Kg=3

在进行拼接 s+t+e7c398ffcb2d4824b4d0a703e38eb0bb s是上面拼接的字符串 t是json里面的13位时间戳 e7c398ffcb2d4824b4d0a703e38eb0bb(是固定字符串)

最终拼接结果： 假设定义e值 K+s7qzwjiqPumZu8DpmV9sJv630oWnJiFc9alzSZxLoKGyk5wbQVY/rzbrfguwstWW3h03PvYxm71jg8+4RLq5ih5PINR5a8GkCgtyPCA18KwafW33A1ff3YqmrCRaWjCsPg2PZ8IE4eDH53Upz1dZ/DX6wmQr9mKcksMHiO5Kg=31679032038779e7c398ffcb2d4824b4d0a703e38eb0bb

再将最终拼接结果e值进行MD5 MD5值就是encStr
