业务功能背景描述 ，需要通过web页面访问本地服务程序实现启动第三方程序。
具体实现方式在本地实现固定端口的监听，实现接受第三方程序发出的指令及参数，完成逻辑判断，返回信息。
1.监听抽象类：
public abstract class HttpServer
{
protected int port;
protected string ip;
TcpListener listener;
bool is_active = true;
public HttpServer(int port, string ip)
{
if (string.IsNullOrEmpty(ip))
{
this.port = 2341;
this.ip = "127.0.0.1";
}
else
{
this.port = port;
this.ip = ip;
}
}
public void listen()
{
listener = new TcpListener(IPAddress.Parse(ip), port);
listener.Start();
while (is_active)
{
TcpClient s = listener.AcceptTcpClient();
HttpProcessor processor = new HttpProcessor(s, this);
Thread thread = new Thread(new ThreadStart(processor.process));
thread.Start();
Thread.Sleep(1);
}
}
public abstract void handleGETRequest(HttpProcessor p);
public abstract void handlePOSTRequest(HttpProcessor p, StreamReader inputData);
}
2.监听实现类
public class MyHttpServer : HttpServer
{
public MyHttpServer(int port, string ip)
: base(port, ip)
{
}
public override void handleGETRequest(HttpProcessor p)
{
if (p.httpHeaders.ContainsKey("URL"))
{
string url = p.httpHeaders["URL"].ToString();
url = HttpUtility.UrlDecode(url);
if (string.IsNullOrEmpty(p.path))
{
System.Diagnostics.Process.Start(url);
}
else
{
try
{
System.Diagnostics.Process.Start(p.path, url);
}
catch (Exception)
{
System.Diagnostics.Process.Start(url);
}
}
}
Console.WriteLine("request: {0}", p.http_url);
p.writeSuccess();
p.outputStream.WriteLine("<html><body><h1>test server</h1>");
p.outputStream.WriteLine("Current Time: " + DateTime.Now.ToString());
p.outputStream.WriteLine("url : {0}", p.http_url);
p.outputStream.WriteLine("<form method=post action=/form>");
p.outputStream.WriteLine("<input type=text name=foo value=foovalue>");
p.outputStream.WriteLine("<input type=submit name=bar value=barvalue>");
p.outputStream.WriteLine("</form>");
}
public override void handlePOSTRequest(HttpProcessor p, StreamReader inputData)
{
Console.WriteLine("POST request: {0}", p.http_url);
string data = inputData.ReadToEnd();
p.writeSuccess();
p.outputStream.WriteLine("<html><body><h1>test server</h1>");
p.outputStream.WriteLine("<a href=/test>return</a><p>");
p.outputStream.WriteLine("postbody: <pre>{0}</pre>", data);
}
}
3.处理解析类
public class HttpProcessor
{
public TcpClient socket;
public HttpServer srv;
// public string callurl = System.Configuration.ConfigurationManager.AppSettings["callurl"];
public string path = "";// System.Configuration.ConfigurationManager.AppSettings["path"];
public string defualturl ="http://www.baidu.com";// System.Configuration.ConfigurationManager.AppSettings["defualt"];
private StreamReader inputStream;
public StreamWriter outputStream;
public String http_method;
public String http_url;
public String http_protocol_versionstring;
public Hashtable httpHeaders = new Hashtable();
private static int MAX_POST_SIZE = 10 * 1024 * 1024; // 10MB
public HttpProcessor(TcpClient s, HttpServer srv)
{
this.socket = s;
this.srv = srv;
this.path = BrowsersData();
}
public string BrowsersData()
{
string path = "";
RegistryKey browsersKey;
browsersKey = Registry.LocalMachine.OpenSubKey(@"SOFTWAREWOW6432NodeClientsStartMenuInternet");
if (browsersKey == null)
browsersKey = Registry.LocalMachine.OpenSubKey(@"SOFTWAREClientsStartMenuInternet");
using (browsersKey)
{
string[] subKeys = browsersKey.GetSubKeyNames();
string locationPath = @"DefaultIcon";
Hashtable ht = new Hashtable();
foreach (string key in subKeys)
{
RegistryKey appLocationKey = browsersKey.OpenSubKey(key + locationPath);
// Console.WriteLine("{0}:{1}", key, (string)appLocationKey.GetValue(null));
string key1 = key.ToUpper();
string pathtemp =((string)appLocationKey.GetValue(null)).Split(',')[0];
if (key1.Contains("360"))
{
ht.Add("360", pathtemp);
}
else if (key1.Contains("IE"))
{
ht.Add("IE", pathtemp);
}
else if (key1.Contains("TSB"))
{
ht.Add("TSB", pathtemp);
}
else if (key1.Contains("CHROME"))
{
ht.Add("CHROME", pathtemp);
}
else
{
ht.Add(key, pathtemp);
}
appLocationKey.Close();
}
if (ht.Contains("CHROME"))
{
path = ht["CHROME"].ToString();
return path;
}
if ((ht.Contains("TSB")))
{
path = ht["TSB"].ToString();
return path;
}
if ((ht.Contains("360")))
{
path = ht["360"].ToString();
return path;
}
if ((ht.Contains("IE")))
{
path = ht["IE"].ToString();
return path;
}
return path;
}
}
public void process()
{
// bs = new BufferedStream(s.GetStream());
inputStream = new StreamReader(socket.GetStream());
outputStream = new StreamWriter(new BufferedStream(socket.GetStream()));
try
{
parseRequest();
readHeaders();
if (http_method != null)
{
if (http_method.Equals("GET"))
{
handleGETRequest();
}
else if (http_method.Equals("POST"))
{
handlePOSTRequest();
}
}
}
catch (Exception e)
{
Console.WriteLine("异常消息: " + e.ToString());
writeFailure();
}
outputStream.Flush();
// bs.Flush(); // flush any remaining output
inputStream = null; outputStream = null; // bs = null;
socket.Close();
}
public void parseRequest()
{
String request = inputStream.ReadLine();
if (request == null)
{
request = "";
}
string[] tokens = request.Split(' ');
if (tokens.Length != 3)
{
Console.WriteLine("starting no invalid http request line");
}
else
{
http_method = tokens[0].ToUpper();
http_url = tokens[1];
http_protocol_versionstring = tokens[2];
Console.WriteLine("starting: " + request);
}
}
/// <summary>
/// 获取请求头部信息
/// </summary>
public void readHeaders()
{
Console.WriteLine("readHeaders()");
String line;
while ((line = inputStream.ReadLine()) != null)
{
if (line.Equals(""))
{
Console.WriteLine("got headers");
return;
}
int separator = line.IndexOf(':');
if (separator == -1)
{
throw new Exception("invalid http header line: " + line);
}
String name = line.Substring(0, separator);
int pos = separator + 1;
while ((pos < line.Length) && (line[pos] == ' '))
{
pos++; // strip any spaces
}
string value = line.Substring(pos, line.Length - pos);
name = name.ToUpper();
Console.WriteLine("header: {0}:{1}", name, value);
httpHeaders[name] = value;
}
}
public void handleGETRequest()
{
srv.handleGETRequest(this);
}
public void handlePOSTRequest()
{
try
{
Console.WriteLine("get post data start");
int content_len = 0;
MemoryStream ms = new MemoryStream();
string url = defualturl;
if (this.httpHeaders.ContainsKey("CONTENT-LENGTH") || this.httpHeaders.ContainsKey("content-length"))
{
content_len = Convert.ToInt32(this.httpHeaders["CONTENT-LENGTH"]);
Console.WriteLine("Content-Length=" + content_len);
if (content_len > MAX_POST_SIZE)
{
throw new Exception(
String.Format("POST Content-Length({0}) too big for this simple server",
content_len));
}
byte[] buf = new byte[4096];
char[] chaf = new char[1000];
int to_read = content_len;
int numread = this.inputStream.Read(chaf, 0, content_len);
string value = new string(chaf).Trim();
if (value.Split('&').Length>1)
url = value.Split('&')[0].Split('=')[1];
Console.WriteLine("url" + url);
buf = Encoding.UTF8.GetBytes(value);
ms.Write(buf, 0, buf.Length);
ms.Seek(0, SeekOrigin.Begin);
}
url = HttpUtility.UrlDecode(url);
Console.WriteLine( "url:" + url);
if ( string.IsNullOrEmpty(url))
{
url = defualturl;
}
if (string.IsNullOrEmpty(path))
{
System.Diagnostics.Process.Start( url);
}
else
{
try
{
System.Diagnostics.Process.Start(path, url);
}
catch (Exception )
{
System.Diagnostics.Process.Start( url);
}
}
//PostHttp(callurl,"","application/x-www-form-urlencoded");
Console.WriteLine("get post data end");
srv.handlePOSTRequest(this, new StreamReader(ms));
}
catch (Exception ex)
{
Console.WriteLine("错误信息" + ex.Message);
}
}
public void writeSuccess()
{
outputStream.Write("HTTP/1.0 200 OK
");
outputStream.Write("Content-Type: text/html
");
outputStream.Write("Access-Control-Allow-Origin: *");
outputStream.Write("Connection: close
");
outputStream.Write("
");
}
public void writeFailure()
{
outputStream.Write("HTTP/1.0 404 File not found
");
outputStream.Write("Connection: close
");
outputStream.Write("
");
}
public string PostHttp(string url, string body, string contentType)
{
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
//application/x-www-form-urlencoded
httpWebRequest.ContentType = contentType;
httpWebRequest.Method = "POST";
httpWebRequest.Timeout = 20000;
byte[] btBodys = Encoding.UTF8.GetBytes(body);
httpWebRequest.ContentLength = btBodys.Length;
httpWebRequest.GetRequestStream().Write(btBodys, 0, btBodys.Length);
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream());
string responseContent = streamReader.ReadToEnd();
httpWebResponse.Close();
streamReader.Close();
httpWebRequest.Abort();
httpWebResponse.Close();
return responseContent;
}
public string CreateHttpRequest(string post)
{
StringBuilder sb = new StringBuilder();
sb.Append(@"<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:exc=访问地址'>");
sb.Append("<soapenv:Header/>");
sb.Append("<soapenv:Body>");
sb.Append("<exc:HisWxEccute>");
sb.Append("<exc:xmlString>");
sb.Append(post);
sb.Append("</exc:xmlString>");
sb.Append("</exc:HisWxEccute>");
sb.Append("</soapenv:Body>");
sb.Append("</soapenv:Envelope>");
return sb.ToString();
}
public void callservice(string req,string Url)
{
string input = CreateHttpRequest(req);
// string result = WebRequestHelper.Current.HttpPost(Url, input, Encoding.UTF8, Encoding.UTF8);
}
}
5.调用实现方法 新建一个windows服务程序 ，并把它做成windows安装程序
public partial class Service1 : ServiceBase
{
public Service1()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
// string input =System.Configuration.ConfigurationManager.AppSettings["port"];
int port = 2000;// Regex.IsMatch(input, @"^[+-]?d*[.]?d*$") ? Convert.ToInt32(input) : 2000;
string ip = "127.0.0.1";//System.Configuration.ConfigurationManager.AppSettings["ip"];
HttpServer httpServer;
httpServer = new MyHttpServer(port,ip);
Thread thread = new Thread(new ThreadStart(httpServer.listen));
thread.Start();
Console.WriteLine("服务已启动！");
}
protected override void OnStop()
{
Console.WriteLine("服务已关闭！");
}
}
1.实现效果如下： 启动本地服务 ，并在浏览器服务2000端口 就会启动相关的程序。
