1  由于(https://www.cnblogs.com/S-Mustard/p/11924227.html)讲到通过telnet访问百度首页,现在通过java代码来实现访问百度服务，获取首页信息。

       try(Socket s=new Socket("www.baidu.com",80);
            Scanner in =new Scanner(s.getInputStream(),"UTF-8");
            BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));){
            StringBuffer sb = new StringBuffer();
            sb.append("GET https://www.baidu.com HTTP/1.1\r\n").append("Host:"+ "www.baidu.com" + "\r\n").append("\r\n");
            out.write(sb.toString());
            out.flush();
            while(in.hasNextLine()){
                System.out.println(in.nextLine());
            }
        }
