Http服务器与客户端Java版

项目需要，一直在学习http相关知识，动手写了一个http服务器的实例，通过该实例可以清楚了解整个http包头及工作原理；（直接能eclipse运行）

package com.cnryb;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.apache.http.Header;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;

import com.sun.net.httpserver.Headers;

public class HttpC {

	/**
	 * @param args
	 * @throws IOException
	 * @throws IllegalStateException
	 */
	public static void main（String[] args） throws IllegalStateException
			IOException {
		HttpClient httpclient = new DefaultHttpClient（）;
		HttpPost httpPost=new HttpPost（“http://127.0.0.1:8765“）;
		HttpResponse response=httpclient.execute（httpPost）;
		HttpEntity entity = response.getEntity（）;
		parseResponseEntity（response）;
		if （entity != null） {
			InputStream instreams = entity.getContent（）;
			BufferedReader bf = new BufferedReader（new InputStreamReader（
					instreams））;
			StringBuilder sb=new StringBuilder（）;
			String line = null;
			while （（line = bf.readLine（）） != null） {
				sb.append（line + “\n“）;
			}
			System.out.println（“\nContent:“+sb.toString（）+“length=“+sb.length（））;
			//httpPost.abort（）;
		}
	}

	private static void parseResponseEntity（HttpResponse response） {
		if （response != null） {
			Header[] headers=response.getAllHeaders（）;
			System.out.println（“Headers:“+“size=“+headers.length）;
			for（Header header:headers）{			
				System.out.println（“Name=“+header.getName（））;
				System.out.println（“Value=“+header.getValue（））;
				System.out.println（“\n“）;
				
			}
			System.out.println（“\n“+“Version=“+response.getProtocolVersion（）+“\nStatus=“+response.getStatusLine（）.getStatusCode（））;	
			
			System.out.println（“Local=“+response.getLocale（）.toString（））;
			
			HttpEntity entity = response.getEntity（）;
			//entity.
			
		}

	}

}
