快递电子面单接口API比较常用在电商、仓储系统和ERP系统，对接后不用下载安装软件，可以直接嵌入系统网站调用。
目前有快递鸟和菜鸟提供集成的电子面单打印接口，分别支持20，15家快递的电子面单打印
1.1 接口
(1)、订单编号(OrderCode)不可重复提交，重复提交系统会返回具体错误代码。
(2)、支持常用20家快递电子面单打印。
(3)、测试地址：:8081/api/eorderservice/
(4)、正式地址：/api/EOrderService
(5)、接口申请：快递鸟网站注册账号申请接口
(6)、单号申请：部分快递需提前申请单号
1.2 系统级和应用级输入参数
1.3 返回结果参数
l同步返回
