以下代码是我从网上找来的，但是一直获取不到post提交的参数，最后经过我的修改，终于可以得到post提交的数据。因为本人在网上找了很久都没有找到相关的资料，特意发出来希望能帮到大家，有什么不足的地方还请大神们指正，小弟不胜感激。
Httpserver代码
1 public void StartListen()
2 {
3 using (HttpListener listerner = new HttpListener())
4 {
5 listerner.AuthenticationSchemes = AuthenticationSchemes.Anonymous;//指定身份验证 Anonymous匿名访问
6 listerner.Prefixes.Add("http://localhost:8080/web/");
7
8 // listerner.Prefixes.Add("http://localhost/web/");
9 listerner.Start();
10 Console.WriteLine("WebServer Start Successed.......");
11 while (true)
12 {
13 //等待请求连接
14 //没有请求则GetContext处于阻塞状态
15 HttpListenerContext ctx = listerner.GetContext();
16 ctx.Response.StatusCode = 200;//设置返回给客服端http状态代码
17 //RequestType=1&Longitude=0.0&Latitude=0.0&RequestSource=xx
18 string RequestType = "";
19 string Longitude = "";
20 string Latitude = "";
21 string RequestSource = "";
22 //获取客户端写入的信息
23 string strRequest = ShowRequestData(ctx.Request);
24 if (!string.IsNullOrEmpty(strRequest))
25 {
26 string[] strR = strRequest.Split(‘&‘);
27 string[] strP = new string[strR.Length];
28 for (int i = 0; i < strR.Length; i++)
29 {
30 strP[i] = strR[i].Split(‘=‘)[1];
31 }
32 RequestType = strP[0];
33 Longitude = strP[1];
34 Latitude = strP[2];
35 RequestSource = strP[3];
36 }
37 string strSend = "";
38
39 if (!string.IsNullOrEmpty(RequestType))
40 {
41 if (RequestType == "1" && !string.IsNullOrEmpty(Longitude) && !string.IsNullOrEmpty(Latitude))
42 {
43 strSend = GetPointWeather(Longitude, Latitude, RequestSource);
44 }
45 if (RequestType == "2")
46 {
47
48 }
49 }
50
51 //使用Writer输出http响应代码
52 using (StreamWriter writer = new StreamWriter(ctx.Response.OutputStream, Encoding.GetEncoding("gb2312")))
53 {
54 writer.WriteLine(strSend);
55 writer.Close();
56 ctx.Response.Close();
57 }
58
59 }
60 //listerner.Stop();
61 }
62 }
GetPointWeather函数是我自己定义的，主要是得到返回给客户端的信息。
获取客户端的输入流
1 public string ShowRequestData(HttpListenerRequest request)
2 {
3 if (!request.HasEntityBody)
4 {
5 Console.WriteLine("No client data was sent with the request.");
6 return "";
7 }
8 System.IO.Stream body = request.InputStream;
9 System.Text.Encoding encoding = request.ContentEncoding;
10 System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
11 if (request.ContentType != null)
12 {
13 Console.WriteLine("Client data content type {0}", request.ContentType);
14 }
15 Console.WriteLine("Client data content length {0}", request.ContentLength64);
16
17 Console.WriteLine("Start of client data:");
18 // Convert the data to a string and display it on the console.
19 string s = reader.ReadToEnd();
20 Console.WriteLine(s);
21 Console.WriteLine("End of client data:");
22 body.Close();
23 reader.Close();
24 // If you are finished with the request, it should be closed also.
25 return s;
26 }
post请求代码：
1 /// <summary>
2 /// 使用Http请求天气信息
3 /// </summary>
4 /// <param name="RequestType">请求类别（1：点预报 2：镇预报）</param>
5 /// <param name="Longitude">经度（如果是镇预报请求 值为空）</param>
6 /// <param name="Latitude">纬度（如果是镇预报请求 值为空）</param>
7 /// <param name="RequestSource">请求来源</param>
8 public void GetWeatherByHttp(string RequestType, string Longitude, string Latitude, string RequestSource)
9 {
10 string strURL = "http://localhost:8080/web/";
11 System.Net.HttpWebRequest request;
12 request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);
13 //Post请求方式
14 request.Method = "POST";
15 //内容类型
16 request.ContentType = "application/x-www-form-urlencoded";
17 //参数经过URL编码
18 Encoding myEncoding = Encoding.GetEncoding("gb2312");//GetEncoding("gb2312")
19 string paraUrlCoded = HttpUtility.UrlEncode("RequestType", myEncoding);
20 paraUrlCoded += "=" + HttpUtility.UrlEncode(RequestType, myEncoding);
21 paraUrlCoded += "&" + HttpUtility.UrlEncode("Longitude", myEncoding);
22 paraUrlCoded += "=" + HttpUtility.UrlEncode(Longitude, myEncoding);
23 paraUrlCoded += "&" + HttpUtility.UrlEncode("Latitude", myEncoding);
24 paraUrlCoded += "=" + HttpUtility.UrlEncode(Latitude, myEncoding);
25 paraUrlCoded += "&" + HttpUtility.UrlEncode("RequestSource", myEncoding);
26 paraUrlCoded += "=" + HttpUtility.UrlEncode(RequestSource, myEncoding);
27 byte[] payload;
28 //将URL编码后的字符串转化为字节
29 payload = System.Text.Encoding.ASCII.GetBytes(paraUrlCoded);
30 //设置请求的ContentLength
31 request.ContentLength = payload.Length;
32 //获得请求流
33 Stream writer = request.GetRequestStream();
34 //将请求参数写入流
35 writer.Write(payload, 0, payload.Length);
36 //关闭请求流
37 writer.Close();
38 System.Net.HttpWebResponse response;
39 //获得响应流
40 response = (System.Net.HttpWebResponse)request.GetResponse();
41 System.IO.Stream s;
42 s = response.GetResponseStream();
43 string StrDate = "";
44 string strValue = "";
45 StreamReader Reader = new StreamReader(s, Encoding.Default);
46 while ((StrDate = Reader.ReadLine()) != null)
47 {
48 strValue += StrDate + "\r\n";
49 }
50 // txtInfo.Text = strValue;
51 Reader.Close();
52 }
