中国邮政包裹快递查询（中国邮政物流官网）

如何利用快递鸟提供的接口来查询邮政快递的物流轨迹。

讲解之前我们来看一下，接口完成以后的实际显示效果

以下是产品应用截图，调用快递鸟接口获得的轨迹信息：

实际上快递鸟返回的报文信息会更详细，在给客户展示的信息可根据产品需要来封装返回轨迹信息。

现在我们来聊一聊具体实现！

首先我们准备好需要用到的资源，

测试商户ID：

test1617571

测试API key：

554343b2-7252-439b-b4eb-1af42c8f2175(此Key仅限测试环境使用)

API测试地址：

http://sandboxapi.kdniao.com:8080/kdniaosandbox/gateway/exterfaceInvoke.json

我以C#开发为例来讲解

接下来，我们讲解一下请求参数

请求系统级参数说明：

备注：R-必填（Required），O-可选（Optional），C-报文中该参数在一定条件下可选（Conditional）

这里提到了系统级参数，也相当于是公用参数，这些参数是调用每个接口都是必须要传参的。

接口参数：

接口参数，也叫业务参数，请求的业务接口不同，参数的字段，内容也不同，是跟着业务变化的，这里我们实现的是即时查询接口，请求指令类型：1002，快递鸟官网要求必须传递快递公司编码和物流单号 ，邮政快递的编码是YZPY

如要查看其他快递公司的编码，点击此链接：

正如我前面的轨迹截图，邮政快递的编码是YZPY，物流单号是9861545869525

业务参数报文组合如下：

{'OrderCode':'','ShipperCode':'YZPY','LogisticCode':'9861545869525'}

请求的完整报文（URL编码以后）：

RequestData=%0d%0a++++++++++++%7b%27OrderCode%27%3a%27%27%2c%27ShipperCode%27%3a%27YZPY%27%2c%27LogisticCode%27%3a%279861545869525%27%7d%0d%0a++++++++&EBusinessID=1264783&RequestType=1002&DataSign=MjQ2YWZiMTU1Mzc5YmFiMTFkMWYyYjI3YTliMjRkYmU%3d&DataType=2

未编码的请求报文：

RequestData=

{'OrderCode':'','ShipperCode':'YZPY','LogisticCode':'9861545869525'}

&EBusinessID=1264783&RequestType=1002&DataSign=MjQ2YWZiMTU1Mzc5YmFiMTFkMWYyYjI3YTliMjRkYmU=&DataType=2

返回的报文信息：

{

"LogisticCode": "9861545869525",

"ShipperCode": "YZPY",

"Traces": [

{

"AcceptStation": "【邮政仙居包快部】已收件,揽投员:周峰,电话:18358689325",
