今天我们来聊如何使用快递鸟提供的接口来查询圆通快递的物流轨迹。解说之前我们来看一下，接口完成以后的实际显示效果以下是我挪用快递鸟接口获得的中通物流轨迹信息，显示的界面效果需要自己开发：现在我们来聊一聊详细实现！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仅限测试情况使用)API测试地址：http://sandboxapi.kdniao.com:8080/kdniaosandbox/gateway/exterfaceInvoke.json我以C#开发为例来解说，如果还没有注册快递鸟，或者还不知道如何获取API Key，可以会见这个视频教程：https://v.qq.com/x/page/z3068yfw0fl.html（注册登陆获取快递鸟API Key）接下来，我们解说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，这些参数是挪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，请求的业务接口差别，参数的字段，内容也差别，是随着业务变化的，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通报快递公司编码和物流单号 ，圆通快递的编码是YTO如要检察其他快递公司的编码，点击此链接：http://www.kdniao.com/documents正如我前面的轨迹截图，圆通快递的编码是YTO，物流单号是78120038107849业务参数报文组合如下：{'OrderCode':'','ShipperCode':'YTO','LogisticCode':'YT4313813113511'}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%27YTO%27%2c%27LogisticCode%27%3a%27YT4313813113511%27%7d%0d%0a++++++++&EBusinessID=1617571&RequestType=1002&DataSign=YjUxYzNlYTBiMjYwYjIzZjE4ZGQ4ZjgyYjJhNGRiZjQ%3d&DataType=2未编码的请求报文：RequestData={'OrderCode':'','ShipperCode':'YTO','LogisticCode':'YT4313813113511'} &EBusinessID=1617571&RequestType=1002&DataSign=YjUxYzNlYTBiMjYwYjIzZjE4ZGQ4ZjgyYjJhNGRiZjQ=&DataType=2返回的报文信息：{"LogisticCode": "YT4313813113511","ShipperCode": "YTO","Traces": [{"AcceptStation": "【山东省青岛市胶州市公司】 已收件 取件人: 张茂盛 (18521137295)","AcceptTime": "2019-12-29 18:15:41"}, {"AcceptStation": "【山东省青岛市胶州市公司】 已打包","AcceptTime": "2019-12-29 18:41:22"}, {"AcceptStation": "【山东省青岛市胶州市】 已发出 下一站 【青岛转运中心公司】","AcceptTime": "2019-12-29 18:44:43"}, {"AcceptStation": "【青岛转运中心公司】 已收入","AcceptTime": "2019-12-29 19:40:51"}, {"AcceptStation": "【青岛转运中心】 已发出 下一站 【深圳转运中心公司】","AcceptTime": "2019-12-29 20:10:01"}, {"AcceptStation": "【深圳转运中心公司】 已收入","AcceptTime": "2019-12-31 13:39:41"}, {"AcceptStation": "【深圳转运中心】 已发出 下一站 【广东省深圳市宝安区机场公司】","AcceptTime": "2019-12-31 14:04:58"}, {"AcceptStation": "【广东省深圳市宝安区机场公司】 已收入","AcceptTime": "2020-01-01 01:43:02"}, {"AcceptStation": "【广东省深圳市宝安区机场公司】 派件中 派件人: 罗家宁 电话 13924819329 如有疑问，请联系：0755-27393821","AcceptTime": "2020-01-01 09:36:26"}, {"AcceptStation": "客户签收人: B5超人 已签收 谢谢使用圆通速递，期待再次为您服务 如有疑问请联系：13924819329，投诉电话：0755-27393821","AcceptTime": "2020-01-02 12:52:32"}],"State": "3","EBusinessID": "1617571","Success": true} {"OrderCode": "012657018199","ShipperCode": "STO","PayType": 1,"MonthCode": "1234567890","ExpType": 1,"Sender": {"Company": "LV","Name": "Taylor","Mobile": "15018442396","ProvinceName": "上海","CityName": "上海市","ExpAreaName": "青浦区","Address": "明珠路"},"Receiver": {"Company": "GCCUI","Name": "Yann","Mobile": "15018442396","ProvinceName": "北京","CityName": "北京市","ExpAreaName": "向阳区","Address": "三里屯街道"},"Commodity": [{"GoodsName": "鞋子","Goodsquantity": 1,"GoodsWeight": 1}],"Weight": 1,"Quantity": 1,"Volume": 0,"Remark": "小心轻放"} C#关键代码：/// <summary> /// 即时查询物流轨迹 /// </summary> /// <param name="url">http://sandboxapi.kdniao.com:8080/kdniaosandbox/gateway/exterfaceInvoke.json</param> /// <param name="eBusinessID">test1617571</param> /// <param name="appKey">554343b2-7252-439b-b4eb-1af42c8f2175</param> /// <param name="requestData">{'OrderCode':'','ShipperCode':'ZTO','LogisticCode':'78120038107849'}</param> /// <returns></returns> public string getOrderTracesByJson(string url,string eBusinessID, string appKey, string requestData) { Dictionary<string, string> param = new Dictionary<string, string>();
