firefox的fidder插件

而Java程序需要设置proxy才能生效：

[java] view plain copy
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。
[java] view plain copy
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;

/**
*@author www.zuidaima.com
**/
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();
}
}

}
