如何使用快递鸟提供的接口来查询邮政快递的物流轨迹。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产物应用截图，挪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凭据产物需要来封装返回轨迹信息。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 ，邮政快递的编码是YZPY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，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", "AcceptTime": "2020-02-19 16:10:29" }, { "AcceptStation": "脱离【邮政仙居包快部】,下一站【仙居中心】", "AcceptTime": "2020-02-19 16:10:33" }, { "AcceptStation": "到达【浙江仙居县处置惩罚中心】", "AcceptTime": "2020-02-19 16:10:34" }, { "AcceptStation": "脱离【浙江仙居县处置惩罚中心】,下一站【台州中心局邮件处置惩罚中心】", "AcceptTime": "2020-02-21 11:13:33" } ], "State": "2", "EBusinessID": "1264783", "Success": true}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>();
