一。1) 支持的传输协议
http ，暂时只支持HTTP协议进行通信。
(2) 支持的数据传输格式
Json ，所有接口暂只支持json消息格式。
(3) 编码格式：UTF-8
交互编码格式统一用
UTF-8，避免传递中文数据出现乱码。
(4) 安全验证
在数据传输过程中，为避免数据被篡改，需要对数据进行加密。
a.
在传输的参数中，既要传递原始的json字符串params，又要传输加密后的摘要digest.
摘要的生成规则是
base64(MD5(params+apikey+timestamp)).
params 参数表的json格式
/// <summary> /// 德邦密文生成器 /// </summary> /// <param name="param"></param> /// <returns></returns> public static string createdigest(string param) { byte[] buffer = System.Text.Encoding.GetEncoding("UTF-8").GetBytes(param); System.Security.Cryptography.MD5CryptoServiceProvider check; check = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] somme = check.ComputeHash(buffer); string ret = ""; foreach (byte a in somme) { if (a < 16) ret += "0" + a.ToString("X"); else ret += a.ToString("X"); } string re = Convert.ToBase64String(System.Text.Encoding.GetEncoding("UTF-8").GetBytes(ret.ToLower())); return re; } /// <summary> /// 德邦时间差生成 /// </summary> /// <returns></returns> public static string createTimestamp() { TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0); string time = Convert.ToInt64(ts.TotalMilliseconds).ToString(); return time; }
Post 信息 http:
Uri myUri = new Uri("http://58.40.17.67/dop/order/alterOrder.action"); Encoding myEncoding = Encoding.GetEncoding("gb2312"); UTF8Encoding encoding2 = new UTF8Encoding(); string sendPrams2 = System.Web.HttpUtility.UrlEncode("companyCode", myEncoding) + "=" + System.Web.HttpUtility.UrlEncode(COMPARNY, myEncoding) + "&" + System.Web.HttpUtility.UrlEncode("params", myEncoding) + "=" + System.Web.HttpUtility.UrlEncode(jsonSaveOrder, encoding2) + "&" + System.Web.HttpUtility.UrlEncode("digest", myEncoding) + "=" + System.Web.HttpUtility.UrlEncode(digest, myEncoding) + "&" + System.Web.HttpUtility.UrlEncode("timestamp", myEncoding) + "=" + System.Web.HttpUtility.UrlEncode(time, myEncoding); HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(myUri); webRequest.Method = "POST"; webRequest.ContentType = "application/x-www-form-urlencoded"; byte[] setStr = System.Text.Encoding.UTF8.GetBytes(sendPrams2); webRequest.ContentLength = setStr.Length; using (System.IO.Stream s = webRequest.GetRequestStream()) { s.Write(setStr, 0, setStr.Length); s.Close(); } try { HttpWebResponse httpWebResponse = (HttpWebResponse)webRequest.GetResponse(); using (System.IO.StreamReader sr = new System.IO.StreamReader(httpWebResponse.GetResponseStream(), System.Text.Encoding.UTF8)) { string returnMessage = sr.ReadToEnd();
异步操作：
Task task = new Task(()
=>
{}）；
task.Start();
（5）WCF 。。。
