本人最近通过自己动手处理http请求，对http协议、Jetty以及HttpClient有了更深刻的理解，特在此与大家分享。
此图是http协议的请求格式。根据请求方法，有get和post之分。get和post的区别在于参数传递的方式：post的参数就是请求包体那一行；get的参数跟在URL后面，也就没有请求包体。
get方式的请求格式
GET /search?hl=zh-CN&source=hp&q=domety&aq=f&oq= HTTP/1.1 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint,
application/msword, application/x-silverlight, application/x-shockwave-flash, */* Referer: <a href="http://www.google.cn/">http://www.google.cn/</a> Accept-Language: zh-cn Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; TheWorld) Host: <a href="http://www.google.cn">www.google.cn</a> Connection: Keep-Alive Cookie: PREF=ID=80a06da87be9ae3c:U=f7167333e2c3b714:NW=1:TM=1261551909:LM=1261551917:S=ybYcq2wpfefs4V9g;

post方式的请求格式
POST /search HTTP/1.1 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint,
application/msword, application/x-silverlight, application/x-shockwave-flash, */* Referer: <a href="http://www.google.cn/">http://www.google.cn/</a> Accept-Language: zh-cn Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; TheWorld) Host: <a href="http://www.google.cn">www.google.cn</a> Connection: Keep-Alive Cookie: PREF=ID=80a06da87be9ae3c:U=f7167333e2c3b714:NW=1:TM=1261551909:LM=1261551917:S=ybYcq2wpfefs4V9g;

所以，对请求进行解析的时候需要区分。
1、用Jetty捕获请求
直接上代码
1 package test; 2 import org.eclipse.jetty.server.Request; 3 import org.eclipse.jetty.server.Server; 4 import org.eclipse.jetty.server.handler.AbstractHandler; 5 6 import javax.servlet.ServletException; 7 import javax.servlet.http.HttpServletRequest; 8 import javax.servlet.http.HttpServletResponse; 9 10 public class JettyServer { 11 public static void main(String[] args) { 12 try { 13 // 进行服务器配置 14 Server server = new Server(8888); 15 server.setHandler(new MyHandler()); 16 // 启动服务器 17 server.start(); 18 server.join(); 19 } catch (Exception e) { 20 e.printStackTrace(); 21 } 22 } 23 } 24 25 class MyHandler extends AbstractHandler { 26 27 @Override 28 public void handle(String target, Request baseRequest, 29 HttpServletRequest request, HttpServletResponse response) 30 throws IOException, ServletException { 31 //写自己的处理 32 } 33 34 }
