报文格式为：JSON

请求报文：{"mchnt_cd" :"商户代码", "message"："密文体"}

密文是由明文封装成json字符串 商户用富友公钥加密，富友在用富友私钥解密

#

请求明文格式如下：

#

{

"mchnt_cd" :"商户代码",

"message"："{"mchnt_cd":"0002900F0096235","order_date":"20200917","order_id":"10771600324085063","ver":"1.0.0"}"

}

对message明文json字符串进行加密 最终得到密文报文体如下：

#

{

"mchnt_cd" :"商户代码",

"message":"uX7DcjQfDmmu3SiCoANd2sUmYAN8fifC2QFuIilyFgT146h2Navc
