业务功能

• 接口组使用说明，本接口专门为2g网络接口设计，在网络环境恶劣的情况下，下游可调用本接口组进行交易。
  本接口转为2g网络使用，通讯方式使用socket。
  签名可以传16位（前16位）、也支持32位，为提高传输效率，建议使用16位签名。

  所有请求参数不能含中文、通知地址必须以http开头
  如果机构号错误或系统异常，签名的key为空字符串。
  签名字符不需要传递字符串的长度

• 所以接口调用必须传递accessid、sign参数。

• 公共返回参数return_code、签名

• 本系统接口，仿照银联8583报文格式，去除位图和厂商等信息、开发人员严格按照文档中参数的顺序进行签名和发送
  发送格式参数字节长度使用BCD码 + 参数ASCII字节码
  例如：outer_order_no = test000000001;
  长度 bcd(lenth(test000000001)) 1字节
  参数值 outer_order_no.getBytes()
  然后拼接长度和参数值

• 示例代码如下:
