如果通过JAVA重启路由器和获取IP地址

1、路由器的用户名和密码我是知道，这里不是hacker技术，是为了方便

2、借助了Fiddler这个工具来对路由器访问的请求进行解析

3、通过Fiddler这个工具让我们了解到DI-504应用的是Basic这个认证方式

4、参考代码：

package com.van.client;

import java.io.IOException;  
import java.io.InputStream;
import java.net.HttpURLConnection;  
import java.net.MalformedURLException;  
import java.net.URL;  
/**

public class Router {  
    private static final String USERNAME_PASSWORD = "admin:a";  
    public Router() {  
        this.disconnect();  
    }  
    
    //http://192.168.3.1/do_cmd.htm?CMD=SYS_CONF&CCMD=0&nowait=1重启路由器
    private void disconnect() {  
        String urlStr = "http://192.168.3.1/info.htm";  
        this.runCgi(urlStr, USERNAME_PASSWORD);  
    }  
  
    private void runCgi(String urlStr, String authorizationStr) {  
        URL xUrl = null;  
        HttpURLConnection xHuc = null;  
        try {  
            xUrl = new URL(urlStr);  
            if (xUrl != null) {  
                xHuc = (HttpURLConnection) xUrl.openConnection();  
                if (xHuc != null) {  
                    if (!"".equals(authorizationStr)) {  
                        xHuc.setRequestProperty("Authorization", "Basic "  
                                + Base64.encodeBytes(USERNAME_PASSWORD  
                                        .getBytes()));  
                    }   
                    xHuc.setRequestProperty("Content-Length", "0");  
                    xHuc.setRequestProperty("Content-Type",  
                            "application/x-www-form-urlencoded");  
                    xHuc.connect();  
                    String aa = xHuc.getResponseMessage();  
                    ////下面这些是用来获取IP地址的
                    InputStream in=xHuc.getInputStream();
                    int chint=0;
                    StringBuffer sb=new StringBuffer();
                    while((chint=in.read())!=-1){
                    	sb.append((char)chint);
                    }
                    String html=sb.toString();
                    int first=html.indexOf("wanIP=\"");
                    String content=html.substring(459,471);
                    System.out.println(content);  
                }  
            }  
        } catch (MalformedURLException e) {  
            e.printStackTrace();  
        } catch (IOException e) {  
            e.printStackTrace();  
        } finally {   
            if (xHuc != null) {  
                xHuc.disconnect();  
            }  
        }  
    }  
    public static void main(String[] args) {  
        new Router();  
    }
  
}  

  其中文中引用到的Base64的java文件在插件里面，还有一些API说明
