- // 1、表单提交方式:form-data
- // 示例:1B2M2Y8AsgTpgAmY7PhCfg==
- // 2、请求头部参数
- // 参数1:sign(签名值,具体算法参考一下的前面算法)
- // 参数2:timestamp(时间戳,13位)
- // 3、请求体参数:
- // 参数1:appId(appId值,每个接入者唯一一个)
- // 参数2:timestamp(时间戳,13位,与上述一致)
- // 参数3:bizData(json字符串,举个例子,比方说要传合同编号如:{"contractNo":"0001"})

- // 4.1、将上述3所属的bizData(json字符串),按照阿拉伯字母排序(如:{"ba":1,"ac":2}--->{"ac":2,"ba":1}),
