问题描述
通过HttpURLConnection我可以轻松的获取网站数据：public class NewSocket {public static String getNetData(String host) throws IOException {HttpURLConnection conn = (HttpURLConnection) new URL(host).openConnection();InputStream inputStream = conn.getInputStream();int len = 1;byte[] buffer = new byte[1024];ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();while ((len = inputStream.read(buffer)) != -1) {byteArrayOutputStream.write(buffer, 0, len);}return new String(byteArrayOutputStream.toByteArray());}public static void main(String[] args) {try {System.out.println(NewSocket.getNetData("http://localhost:8080/videoweb"));} catch (IOException e) {e.printStackTrace();}}}但是通过socket的话，我不知道怎么访问web数据。public class OtherNewSocket {public static String getNetData(String host, int port) throws IOException {Socket socket = new Socket(host, port);byte[] buffer = new byte[1024];ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();int len = 0;while ((len = socket.getInputStream().read(buffer)) != -1) {byteArrayOutputStream.write(buffer);}return new String(byteArrayOutputStream.toByteArray());}public static void main(String[] args) {try {System.out.println(OtherNewSocket.getNetData("localhost", 8080));} catch (IOException e) {e.printStackTrace();}}}求指教,然后我想知道通过url访问和通过socket访问有什么不同点，我理解的就是，通过url访问访问的直接是某个项目网页地址，而通过socket访问呢，则是端对端的访问，也就是访问的其实是目标服务器的某一端口上的进程，但是如果要具体访问进程上的项目，也就是默认欢迎页面index.jsp,又该如何做呢 问题补充：khan 写道
解决方案
你需要看下http协议的底层啊，live.html是一个资源路径啊，获取别的就写别的了，只是举个例子。你可以参看http协议
解决方案二：
别忘给分啊，兄弟！
解决方案三：
package com.iteye.wenda.socket;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class HttpGetWebPage {public static void main(String[] args) {try {Socket socket = new Socket("mdcc.csdn.net", 80);BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream())); PrintWriter out = new PrintWriter(socket.getOutputStream(),true);out.print("GET /live.html HTTP/1.1");out.println("/n");String rep = "";while(null!=(rep = reader.readLine())){System.out.println(rep);}out.flush();out.close();reader.close();} catch (UnknownHostException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}
解决方案四：
模拟HTTP发送一个get请求即可
