firefox的fidder插件

而java程序需要设置proxy才能生效：

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("127.0.0.1", 8888));
URL serverUrl = new URL(url);
HttpURLConnection conn = (HttpURLConnection) serverUrl.openConnection(proxy); 

详细代码请下载。

package com.zuidaima.http;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.URL;


/**

public class Http302Redirect {

	public static void main(String[] args) {
		try {
			String url = "http://www.zuidaima.com/";
			System.out.println("访问地址:" + url);

			Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,
					new InetSocketAddress("127.0.0.1", 8888));
			URL serverUrl = new URL(url);
			HttpURLConnection conn = (HttpURLConnection) serverUrl
					.openConnection(proxy);
			conn.setRequestMethod("GET");

			conn.addRequestProperty("Accept-Charset", "UTF-8;");
			conn.addRequestProperty("User-Agent",
					"Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.8) Firefox/3.6.8");
			conn.addRequestProperty("Referer", "http://javaniu.com/");
			conn.connect();
			BufferedReader reader = new BufferedReader(new InputStreamReader(
					conn.getInputStream()));
			StringBuffer buffer = new StringBuffer();
			String line = reader.readLine();
			while (line != null) {
				buffer.append(line).append("\r\n");
				line = reader.readLine();
			}
			reader.close();
			conn.disconnect();
			System.out.println(buffer);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
