该博客给出了C#串通京东接口的demo代码。代码中构建了请求参数的JObject对象，对参数进行压缩、拼接，计算签名，处理中文参数编码，创建HTTP请求并发送，最后获取响应结果。还包含了签名生成和MD5加密的方法。

 1  public string Get(int id)
 2         {
 3 
 4             JObject o = new JObject(
 5                 new JProperty("billNo", "ESL1363593563"),
 6                 new JProperty("billType", "24"),
 7                 new JProperty("pageNo", "1"),
 8                 new JProperty("pageSize", "10"),
 9                 new JProperty("queryType ", "1")
10                 );
11             //压缩str,用于得到sign的值
12             string str = "360buy_param_json" + o.ToString() + "access_token" + 123 + "app_key" + 123 + "method" + 123 + "timestamp=" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "v2.0";
13             //完整str
14             string str1 = "360buy_param_json=" + o.ToString() + "&access_token=" + 123 + "&app_key=" + 123 + "&method=" + 123 + "&timestamp=" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "&v=2.0";
15 
16             string end = "yourappSecret" + str + "yourappSecret";
17             string md5 = StrToMD5(end);//得出来sign  
18             //最后拼接url：
19             string endstr = str1 + "&sign=" + md5;
20             //经常用到url中含有中文字符的需要对其进行字符串编码和解码，所以这里就用了这个System.Web.HttpUtility.UrlEncode，
21             c#asp.net url 传递中文参数要使用 System.Web.HttpUtility.UrlEncode 而不能使用Server.UrlEncode
22             string allStr = System.Web.HttpUtility.UrlEncode(endstr, System.Text.Encoding.UTF8);

28             WebReq.ContentLength = allStr.Length;
29             Stream PostData = WebReq.GetRequestStream();
30             PostData.Write(bufferB, 0, bufferB.Length);
31             PostData.Close();

35             string backstr = sr.ReadToEnd();
36             backstr = HttpUtility.UrlDecode(backstr);
37             Console.WriteLine(WebResp.StatusCode);
