下面是我的服务端：

@WebServlet("/user")

public class UserServlet extends HttpServlet {



	@Override

	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

		req.setCharacterEncoding("utf-8");

		Enumeration<String> e=req.getHeaderNames();

		while(e.hasMoreElements()){

			String key=e.nextElement();

			System.out.println(key+"="+req.getHeader(key));

		}

		resp.setCharacterEncoding("utf-8");

		resp.setContentType("text/html;charset=utf-8");	

		PrintWriter out=resp.getWriter();

		String name=req.getParameter("name");

		if("kaiqi".equals(name)){

			System.out.println("通过验证");

			out.println("<html><head><title></title></head><body>successed<body></html>");

		}else{

			System.out.println("验证未通过");

			out.println("<html><head><title></title></head><body>failed<body></html>");

		}

		

	}





}

下面是我的android客户端，只有一个按钮控件：

public class MainActivity extends AppCompatActivity {

    private Button loginBtn;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        loginBtn=(Button)findViewById(R.id.loginBtn);



        loginBtn.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                new Thread(){

                    @Override

                    public void run() {

                        String urlStr="http://192.168.1.101:8080/AndroidNetTest/user?name=kaiqi";

                         //String urlStr="http://www.baidu.com";

                        try {

                            URL url=new URL(urlStr);

                            HttpURLConnection con= (HttpURLConnection) url.openConnection();

                            InputStream in=con.getInputStream();

                            byte[] buf=new byte[1024];

                            in.read(buf);

                            Log.i("wjq",new String(buf,"utf-8"));

                        } catch (MalformedURLException e) {

                            e.printStackTrace();

                        } catch (IOException e) {

                            e.printStackTrace();

                        }



                    }

                }.start();

            }

        });



    }

}
