通过HttpListener实现轻量级Web服务器[原创]
由于最近要搞一个P2P项目，所以最近找了份C#版BtTorrent [MonoTorrent]代码，参考参考它对BT协议的实现，在看Tracker模块时发现了这个功能，非常不错，于是就将他单独挖出来，写了个简单测试代码，这东西还是很不错的，有时候还真能派上点用处。
测试代码：
class Program
{
static HttpListener listener;
public static bool Running
{
get { return listener != null; }
}
static void Main(string[] args)
{
Start();
Console.WriteLine("正在监听中....");
while (true)
{
System.Threading.Thread.Sleep(2000);
}
Console.WriteLine("IsOver");
Console.ReadLine();
}
static void Start()
{
if (Running)
return;
listener = new HttpListener();
//这里开启Http 监听
listener.Prefixes.Add("http://127.0.0.1:1234/");//也支持域名形式
listener.Start();
//异步等待URL请求传入
listener.BeginGetContext(EndGetRequest, listener); ;
}
static void Stop()
{
if (!Running)
return;
listener.Close();
listener = null;
}
static void EndGetRequest(IAsyncResult result)
{
HttpListenerContext context = null;
System.Net.HttpListener listener = (System.Net.HttpListener)result.AsyncState;
try
{
context = listener.EndGetContext(result);
HandleRequest(context);
}
catch (Exception ex)
{
Console.Write("Exception in listener: {0}{1}", Environment.NewLine, ex);
}
finally
{
if (context != null)
context.Response.Close();
if (listener.IsListening)
listener.BeginGetContext(EndGetRequest, listener);
}
}
static void HandleRequest(HttpListenerContext context)
{
bool isScrape = context.Request.RawUrl.StartsWith("/scrape", StringComparison.OrdinalIgnoreCase);
string responseStr = "very nice! haha"n来个中文你支持吗？"n";
for (int i = 0; i < context.Request.QueryString.Count; i++)
{
responseStr = responseStr + "query:" + context.Request.QueryString.Keys[i] + "=" + context.Request.QueryString[i] + ""n";
}
Console.WriteLine("good");
byte[] response = System.Text.Encoding.Default.GetBytes(responseStr);
context.Response.ContentType = "text/plain"; //这里的类型随便你写.如果想返回HTML格式使用text/html
context.Response.StatusCode = 200;
context.Response.ContentLength64 = response.LongLength;
context.Response.OutputStream.Write(response, 0, response.Length);
}
}
编译以上代码，运行编译生成出来的.exe文件，这时你的服务器上就开起了基与1234端口的http监听，此时你就可以通过 http://127.0.0.1:1234/?a=11&b=22 的地址格式来访问 该Web服务器了，很方便吧
