1. 物流服务购买
1)登录阿里云平台：https://www.aliyun.com/
2)注册登录阿里云账号，搜索关键字 物流***
3)询问客服，选择合适服务（有些服务调用第三方物流时必须要传快递公司和物流单号，有些可以自动识别快递公司只需要传物流单号即可；有些可以实现国际物流服务，有些只能实现国内物流服务等等内容）
本人综合公司业务最总选择的是全国快递物流查询，如下图所示：
4)购买服务成功后，可获取appKey、和AppCode
2.API接口
调用地址：http(s)://wuliu.market.alicloudapi.com/kdi
请求方式：GET
返回类型：JSON
API 调用：API 简单身份认证调用方法（APPCODE）
API 签名认证调用方法（AppKey& AppSecret）
3.程序实现
