快递查询接口是指快递查询网对外开放的应用程序接口，开发人员能够通过调用该接口与快递查询网进行交互，并基于该接口开发自己的快递查询应用程序。
技术文档请参考快递鸟官网api：免费查询快递接口_100%安全保障_物流即时查询API-快递鸟
（一）接入流程：
1、登录快递鸟官网注册页面注册快递鸟账号
网址：快递单号查询接口_电子面单_APIKey授权申请-快递鸟账号注册
2、登录快递鸟用户管理后台
网址：用户登录_快递鸟API让物流接口对接更简单
接口说明
(1)、接口支持的消息接收方式为HTTP POST，请求方法的编码格式(utf-8)：“application/x-www-form-urlencoded;charset=utf-8”。
(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)、 API测试地址：:8081/api/dist
(4)、API正式地址：/api/dist
(5)、定时推送新的物流信息
(6)、接口秘钥申请：快递鸟（/reg）
