ASP.NET一个简易的WebServer,用控制台程序模拟IIS 托起web服务
写了一个简单WebServer 服务器，可以处理js、css、html、aspx的请求，以及图片、视频代码如下：
public delegate void ProcessRequestHandler(string page, string query, TextWriter writer);
public class WebServer : MarshalByRefObject, IRegisteredObject
{
public void ProcessRequest(string page, string query, TextWriter writer)
{
SimpleWorkerRequest worker = new SimpleWorkerRequest(page, query, writer);
HttpRuntime.ProcessRequest(worker);
}
public void Stop(bool immediate)
{
HostingEnvironment.UnregisterObject(this);
}
}
public class SimpleHttpListener
{
ProcessRequestHandler ProcessRequest;
public void SetProcessRequest(ProcessRequestHandler handler)
{
this.ProcessRequest = handler;
}
static string PhysicRoot = string.Empty;
public void Run()
{
if (!HttpListener.IsSupported)
throw new InvalidOperationException("使用 HttpListener 必须为 Windows XP SP2 或 Server 2003 以上系统！");
string[] prefixes = new string[] { "http://localhost:49152/" };
HttpListener listener = new HttpListener();
foreach (string item in prefixes)
{
listener.Prefixes.Add(item);
}
listener.Start();
Console.WriteLine("开始监听.....");
while (true)
{
HttpListenerContext context = listener.GetContext();
HttpListenerRequest request = context.Request;
Console.WriteLine("{0} {1} HTTP/1.1", request.HttpMethod, request.RawUrl);
HttpListenerResponse response = context.Response;
using (StreamWriter writer = new StreamWriter(response.OutputStream))
{
StringWriter sw = new StringWriter();
string content = string.Empty;
string filename = request.Url.LocalPath.ToLower();
Regex reg = new Regex("(.aspx|.ashx|.svc|.asmx)");
Match m = reg.Match(filename);
if (m.Success)
{
string path = request.Url.AbsolutePath;
string query = request.Url.Query.Replace("?", string.Empty);
string prefx = m.Groups.Value;
if (!filename.EndsWith(prefx))
{
int index = path.IndexOf(prefx);
index = index + prefx.Length;
query = path.Substring(index);
path = path.Substring(0, index);
}
path = Path.GetFileName(path);
this.ProcessRequest(path, query, sw);
content = sw.ToString();
sw.Close();
response.ContentLength64 = Encoding.UTF8.GetByteCount(content);
response.ContentType = "text/html; charset=UTF-8";
writer.Write(content);
}
else
{
string filePath = Path.Combine(PhysicRoot, request.Url.AbsolutePath.Substring(1));
lock (this)
{
byte[] buffer = new byte;
if (File.Exists(filePath))
{
using (StreamReader sr = new StreamReader(filePath))
{
response.ContentLength64 = sr.BaseStream.Length;
int readLength = sr.BaseStream.Read(buffer, 0, buffer.Length);
while (readLength > 0)
{
writer.BaseStream.Write(buffer, 0, readLength);
readLength = sr.BaseStream.Read(buffer, 0, buffer.Length);
}
}
}
else
{
string msg = "not found:" + filePath;
byte[] data = Encoding.UTF8.GetBytes(msg);
writer.BaseStream.Write(data, 0, data.Length);
}
}
}
Console.WriteLine("\r\nProcess Ok.\r\n");
}
if (Console.KeyAvailable)
break;
}
listener.Stop();
}
public static void Start()
{
PhysicRoot = @"C:\Users\majiang\Documents\Visual Studio 2010\Projects\Jquery\Jquery";
WebServer server = CreateWorkerAppDomainWithHost(typeof(WebServer), "/", PhysicRoot) as WebServer;
//WebServer server = ApplicationHost.CreateApplicationHost(typeof(WebServer), "/", @"C:\Users\majiang\Documents\Visual Studio 2010\Projects\Jquery\Jquery") as WebServer;
SimpleHttpListener listener = new SimpleHttpListener();
listener.SetProcessRequest(server.ProcessRequest);
listener.Run();
}
static object CreateWorkerAppDomainWithHost(Type hostType, string virtualPath, string physicalPath)
{
string uniqueAppString = string.Concat(virtualPath, physicalPath).ToLowerInvariant();
string appid = (uniqueAppString.GetHashCode()).ToString("X", CultureInfo.InvariantCulture);
var appmanager = ApplicationManager.GetApplicationManager();
var buildManagerHostType = typeof(HttpRuntime).Assembly.GetType("System.Web.Compilation.BuildManagerHost");
var buildManagerHost = appmanager.CreateObject(appid, buildManagerHostType, virtualPath, physicalPath, false);
buildManagerHostType.InvokeMember("RegisterAssembly", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.NonPublic, null, buildManagerHost, new object[] { hostType.Assembly.FullName, hostType.Assembly.Location });
return appmanager.CreateObject(appid, hostType, virtualPath, physicalPath, false);
}
