NoHttp封装--03 cookie

Posted 2020-11-04 安卓笔记侠

NoHttp请求自动维持Cookie：
   1.支持Session、Cookie、临时Cookie的位置。
   2.支持App重启、关机开机后继续持久化维持。
   3.提供了接口，允许开发者监听Cookie的变化，也可以改变某个Cookie的值。

 

服务器端：

@WebServlet("/login")
public class LoginServlet extends BaseJsonServlet {

    private static final long serialVersionUID = 145646L;

    @Override
    protected String onResponse(HttpServletRequest request, HttpServletResponse response) throws Exception {
        String userName = request.getParameter("userName");
        String userpwd = request.getParameter("userPwd");
        if ("yolanda".equals(userName) && "123".equals(userpwd)) {
            Cookie cookie = new Cookie("userInfo", "yolalasf3153a1");
            cookie.setMaxAge(60 * 1000);
            response.addCookie(cookie);
            return "登录成功";
        } else {
            return "登录失败";
        }
    }

}

客户端：

 1 public class CookieGetActivity extends Activity implements View.OnClickListener {
 2 
 3     private TextView mTvResult;
 4 
 5     @Override
 6     protected void onCreate(Bundle savedInstanceState) {
 7         super.onCreate(savedInstanceState);
 8         setContentView(R.layout.activity_login);
 9         findViewById(R.id.btn_login).setOnClickListener(this);
10         mTvResult = (TextView) findViewById(R.id.tv_result);
11     }
12 
13     @Override
14     public void onClick(View v) {
15         if (v.getId() == R.id.btn_login) {// 登录按钮
16             Request<JSONObject> request = new FastJsonRequest("http://192.168.1.116/HttpServer/login?userName=yolanda&userPwd=123", RequestMethod.GET);
17             CallServer.getInstance().add(this, request, callBack, 0, true, false, true);
18         }
19     }
20 
21     private HttpCallBack<JSONObject> callBack = new HttpCallBack<JSONObject>() {
22         @Override
23         public void onSucceed(int what, Response<JSONObject> response) {
24             JSONObject jsonObject = response.get();
25             String result = "成功了：" + jsonObject.getString("data");
26 
27             // 成功时拿到头
28             Headers headers = response.getHeaders();
29             List<HttpCookie> cookies = headers.getCookies();
30             for (HttpCookie httpCookie : cookies) {
31                 String cookieName = httpCookie.getName();
32                 if ("userInfo".equals(cookieName)) {
33                     // 这里就拿到了你想那的cookie
34                     result += "\\n";
35                     result += httpCookie.getValue();
36                 }
37             }
38             mTvResult.setText(result);
39         }
40 
41         @Override
42         public void onFailed(int what, String url, Object tag, Exception exception, int responseCode, long networkMillis) {
43             mTvResult.setText("失败了" + exception.getClass().getName());
44         }
45     };
46 
47 }
