今天我们来聊如何利用快递鸟提供的接口来查询【申通快递】的物流轨迹。

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，

如果还没有注册快递鸟，或者还不知道如何获取API Key，可以访问这个腾讯视频教程：

https://v.qq.com/x/page/z3068yfw0fl.html（注册登陆获取快递鸟API Key）接下来，我们讲解一下请求参数

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 ，圆通快递的编码是YTO

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，申通快递的编码是STO，物流单号是777007389359024

业务参数报文组合如下：

{'OrderCode':'','ShipperCode':'STO','LogisticCode':'777007389359024'}

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%27STO%27%2c%27LogisticCode%27%3a%27777007389359024%27%7d%0d%0a++++++++&EBusinessID=1617571&RequestType=1002&DataSign=N2I4ZGEzYjkwMzhkZWY0YmM5ZGYxOGNkYjU5MmI2ZTU%3d&DataType=2

未编码的请求报文：

RequestData=

{'OrderCode':'','ShipperCode':'STO','LogisticCode':'777007389359024'}

&EBusinessID=1617571&RequestType=1002&DataSign=N2I4ZGEzYjkwMzhkZWY0YmM5ZGYxOGNkYjU5MmI2ZTU=&DataType=2

返回的报文信息：
