使用代理访问,且获取请求的响应值

//请求获取响应
    public static StringBuffer senGet(String url){
        StringBuffer result=new StringBuffer();
        BufferedReader in =null;
        try {
            URL realUrl = new URL(url);
            // /创建代理服务器
            InetSocketAddress addr = new InetSocketAddress("192.168.11.254", 8080);
            //http代理
            Proxy proxy = new Proxy(Proxy.Type.HTTP, addr); 
            //设置代理访问
            //HttpURLConnection connection1 = (HttpURLConnection) realUrl.openConnection(proxy);// 设置代理访问
            // 打开和URL之间的连接
            HttpURLConnection connection =(HttpURLConnection)realUrl.openConnection(proxy);
            //设置通用的请求属性
            connection.setRequestProperty("accept", "*/*");
            connection.setRequestProperty("connection", "Keep-Alive");
            connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            //连接
            connection.connect();
            
            Map<String,List<String>> map = connection.getHeaderFields();
