这只是一个小Demo，话几十分钟搞出来的。
不废话先上代码。
首先是服务端的
package com.cnryb; import java.io.IOException; import java.io.OutputStream; import java.net.InetSocketAddress; import org.apache.http.HttpStatus; import com.sun.net.httpserver.*; public class HttpSer { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { HttpServer server = HttpServer.create(new InetSocketAddress( "127.0.0.1", 8765), 0); server.createContext("/",new MyResponseHandler()); server.setExecutor(null); // creates a default executor server.start(); } public static class MyResponseHandler implements HttpHandler { @Override public void handle(HttpExchange httpExchange) throws IOException { //针对请求的处理部分 //返回请求响应时，遵循HTTP协议 String responseString = "<font color='#ff0000'>Hello! This a HttpServer!</font>"; //设置响应头 httpExchange.sendResponseHeaders(HttpStatus.SC_OK, responseString.length()); OutputStream os = httpExchange.getResponseBody(); os.write(responseString.getBytes()); os.close(); } } }
容易出现问题的是端口被占用，解决办法
换一个端口，嘿嘿
然后是用java访问该服务器的代码
package com.cnryb; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; 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; 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"); // HttpGet httpgets = new HttpGet("http://127.0.0.1:8765"); // HttpResponse response = httpclient.execute(httpgets); HttpResponse response=httpclient.execute(httpPost); HttpEntity entity = response.getEntity(); 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(sb.toString()); // httpgets.abort(); httpPost.abort(); } } }
这个段代码不只是能够访问这一个服务，别的已经存在的服务器也能够范围，像百度神马的，简单来说就是模拟浏览器请求的
写这些东西的时候，唯一让我纠结的就是那些该死的jar包，为了不让亲们纠结，我把我写好的demo也放上来，里面有jar包的
Live Writer竟然不能放附件？？等会儿手动上传吧
