This article introduces the relevant knowledge of "how to achieve express bird API interface signature in C#". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Code implementation of method call / / E-commerce IDstring eEBusinessID = "test1617571"; / / E-commerce encryption private key, provided by express bird, take care to keep it, do not disclose string appKey= "554343b2-7252-439b-b4eb-1af42c8f2175"; / / request urlstring reqURL = "http://sandboxapi.kdniao.com:8080/kdniaosandbox/gateway/exterfaceInvoke.json";// request instruction string reqType=" 1002 "; / / 2-json string dataType =" 2 " / / character encoding is UTF-8 string charset = "UTF-8"; / / JSON string jsonStr = "{\" OrderCode\ ":\"\ ",\" ShipperCode\ ":\" SF\ ",\" LogisticCode\ ":\" 118461988807\ "}"; / / MD5 (jsonStr+APIKey) to encrypt string md5Str=MD5 (jsonStr+ apiKey, charset); / / Base64 encode md5Str to string base64Str=base64 (md5Str,charset) / / URL encoding (utf-8) string datasign = HttpUtility.UrlEncode (base64Str, charset); / / request message parameter string postStr = "RequestType=reqType&EBusinessID= eEBusinessID&RequestData=jsonStr & DataSign= datasign&DataType=dataType"; / / Communication protocol uses Http protocol Post request method to return track data string post = SendPost (reqURL, postStr) / / the post data obtained is the complete message returned by the express bird. Then you can write a method to parse the json and get the field information in it. C # encapsulated method / string MD5 encryption / Encoding / ciphertext private string MD5 (string str, string charset) {byte [] buffer = System.Text.Encoding.GetEncoding (charset) .GetBytes (str); try {System.Security.Cryptography.MD5CryptoServiceProvider check Check = new System.Security.Cryptography.MD5CryptoServiceProvider (); byte [] somme = check.ComputeHash (buffer); string ret = ""; foreach (byte an in somme) {if (a < 16) ret + = "0" + a.ToString ("X") Else ret + = a.ToString ("X");} return ret.ToLower ();} catch {throw } / base64 Encoding / content / Encoding method / private string base64 (String str, String charset) {return Convert.ToBase64String (System.Text.Encoding.GetEncoding (charset) .GetBytes (str)) } / Post method to submit data, return the source code of the web page / request message parameters / the response result of the remote resource private string SendPost (string url, string postData) {string result = "; byte [] byteData = Encoding.GetEncoding (" UTF-8 ") .GetBytes (postData.ToString ()) Try {HttpWebRequest request = (HttpWebRequest) WebRequest.Create (url); request.ContentType = "application/x-www-form-urlencoded"; request.Referer = url; request.Accept = "* / *"; request.Timeout = 30 * 1000; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) .net CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) "; request.Method =" POST "; request.ContentLength = byteData.Length; Stream stream = request.GetRequestStream (); stream.Write (byteData, 0, byteData.Length); stream.Flush (); stream.Close () HttpWebResponse response = (HttpWebResponse) request.GetResponse (); Stream backStream = response.GetResponseStream (); StreamReader sr = new StreamReader (backStream, Encoding.GetEncoding ("UTF-8")); result = sr.ReadToEnd (); sr.Close (); backStream.Close (); response.Close (); request.Abort () } catch (Exception ex) {result = ex.ToString ();} return result;} "how to implement express bird API interface signature in C#" is introduced here.
