C# 实现快递鸟API接口签名 快递查询对接更高效

接口对接常见的问题基本上是数据签名错误导致的接口联调失败,大家在电商平台调用快递鸟接口时,为了提供对接效率,给大家提供一些方法供大家参考。

虽然前面的问题也要见解,内容太多,也是为了大家更好的高效率看自己想了解的部分。

方法调用的代码实现

//电商ID
string eEBusinessID = "test1617571";
 //电商加密私钥,快递鸟提供,注意保管,不要泄漏
string appKey= "554343b2-7252-439b-b4eb-1af42c8f2175";
 //请求url
string reqURL = "http://sandboxapi.kdniao.com:8080/kdniaosandbox/gateway/exterfaceInvoke.json";
//请求指令 
string reqType="1002";
//2-json 
string dataType = "2"; 
//字符编码采用UTF-8 
string charset = "UTF-8"; 
//JSON字符串string 
string jsonStr = 
"{\"OrderCode\":\"\",\"ShipperCode\":\"SF\",\"LogisticCode\":\"118461988807\"}" ;
//把(jsonStr+APIKey)进行MD5加密
string md5Str=MD5(jsonStr + apiKey, charset);
//把md5Str 进行Base64编码
string base64Str=base64(md5Str,charset);
//进行URL编码 (utf-8)
string datasign = HttpUtility.UrlEncode(base64Str, charset); 
//请求报文参数 
string postStr = "RequestType=reqType&EBusinessID= eEBusinessID&RequestData=jsonStr 
&DataSign= datasign&DataType=dataType"; 
//通讯协议使用Http协议Post请求方式 返回轨迹数据
string post = SendPost(reqURL, postStr);
//获取到的post数据就是快递鸟返回的完整报文,接下来自己写一个解析json的方法就能获取到里面的字段信息。
