快递查询接口通用API（JAVA对接）

摘要：快递查询接口通用是给发货电商用来实现查询快递物流轨迹功能的，接口对接前要先到快递鸟网站申请接口秘钥和对接要求查询接口支持按照运单号查询单个查询，并发不超过个。

快递查询接口通用API是给发货电商用来实现查询快递物流轨迹功能的，接口对接前要先到快递鸟网站申请接口秘钥和APIKEY

对接要求：
(1)、查询接口支持按照运单号查询(单个查询，并发不超过10个/S)。
(2)、指定的物流运单号选择相应的快递公司编码，格式不对或则编码错误都会返失败的信息。如EMS物流单号应选择快递公司编码（EMS）
(3)、返回的物流跟踪信息按照发生的时间升序排列。
(4)、接口指令1002
(5)、接口提供：快递鸟
(6)、请求地址：http://api.kdniao.cc/Ebusines...
