NoHttp封装--02 自定义请求

bean实体类请求：

1.bean

 import java.io.Serializable;
 import com.alibaba.fastjson.annotation.JSONField;

 public class UserInfo implements Serializable {
     private static final long serialVersionUID = 145641645L;

     @JSONField(name = "data")
     private String data;
     @JSONField(name = "error")
     private int error;
     @JSONField(name = "msg")
     private String msg;

     public UserInfo() {
         super();
     }

     public UserInfo(String data, int error, String msg) {
         super();
         this.data = data;
         this.error = error;
         this.msg = msg;
     }
     public String getData() {
         return data;
     }
     public void setData(String data) {
         this.data = data;
     }
     public int getError() {
         return error;
     }
     public void setError(int error) {
         this.error = error;
     }

     public String getMsg() {
         return msg;
     }
     public void setMsg(String msg) {
         this.msg = msg;
     }

     public boolean isSucceed() {
         return  == error;
     }

 }

2.针对bean的request

 import com.alibaba.fastjson.JSON;
 import com.yolanda.nohttp.Headers;
 import com.yolanda.nohttp.JsonObjectRequest;
 import com.yolanda.nohttp.RequestMethod;
 import com.yolanda.nohttp.RestRequest;
 import com.yolanda.nohttp.StringRequest;
 import com.yolanda.nohttptest.bean.UserInfo;

 public class UserInfoRequest extends RestRequest<UserInfo> {

     public UserInfoRequest(String url, RequestMethod requestMethod) {
         super(url, requestMethod);
     }
     public UserInfoRequest(String url) {
         super(url);
     }
     @Override
     public String getAccept() {
         return JsonObjectRequest.ACCEPT;
     }
     @Override
     public UserInfo parseResponse(String url, Headers responseHeaders, byte[] responseBody) {
         UserInfo info = null;
         String string = StringRequest.parseResponseString(url, responseHeaders, responseBody);
         try {
             info = JSON.parseObject(string, UserInfo.class);
         } catch (Exception e) {
             info = new UserInfo();
         }
         return info;
     }
 }

3.具体在activity中使用：

 public class ObjectActivity extends Activity implements View.OnClickListener {

     private final int NOHTTP_LOGIN = 0x01;
     private final int NOHTTP_LOGOUT = 0x02;

     private TextView tvResult;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_object);
         findViewById(R.id.btn_login).setOnClickListener(this);
         findViewById(R.id.btn_logout).setOnClickListener(this);
         tvResult = (TextView) findViewById(R.id.tv_result);
     }

     @Override
     public void onClick(View v) {
         if (v.getId() == R.id.btn_login) {
             UserInfoRequest request = new UserInfoRequest(Constants.LOGIN, RequestMethod.GET);
             request.add("userName", "yolanda");
             request.add("userPwd", "");
             CallServer.getInstance().add(this, request, callBack, NOHTTP_LOGIN, true, false, true);
         } else {
             UserInfoRequest request = new UserInfoRequest(Constants.LOGOUT, RequestMethod.GET);
             CallServer.getInstance().add(this, request, callBack, NOHTTP_LOGOUT, true, false, true);
         }
     }

     private HttpCallBack<UserInfo> callBack = new HttpCallBack<UserInfo>() {

         @Override
         public void onSucceed(int what, Response<UserInfo> response) {
             UserInfo info = response.get();
             if (what == NOHTTP_LOGIN) {// 处理登录结果
                 if (info.isSucceed()) {
                     tvResult.setText("登录接口结果：" + info.getData());
                 }
             } else if (what == NOHTTP_LOGOUT) {// 处理登出结果
                 if (info.isSucceed()) {
                     tvResult.setText("退出接口结果：" + info.getData());
                 }
             }
         }

         @Override
         public void onFailed(int what, String url, Object tag, Exception exception, int responseCode, long networkMillis) {
             tvResult.setText("请求失败");
         }
     };
 }

---

可以解析所有JavaBean的自定义请求

 public class JavaBeanRequest<E> extends RestRequest<E> {

     private Class<E> clazz;

     public JavaBeanRequest(String url, RequestMethod requestMethod, Class<E> clazz) {
         super(url, requestMethod);
         this.clazz = clazz;
     }

     public JavaBeanRequest(String url, Class<E> clazz) {
         this(url, RequestMethod.GET, clazz);
     }

     @Override
     public E parseResponse(String url, Headers responseHeaders, byte[] responseBody) {
         String result = StringRequest.parseResponseString(url, responseHeaders, responseBody);
         try {
             return JSON.parseObject(result, clazz);
         } catch (Exception e) {
             E instance = null;
             try {
                 // 但是前提是传进来的JavaBean必须提供了默认实现
                 instance = clazz.newInstance();
             } catch (InstantiationException e1) {
             } catch (IllegalAccessException e1) {
             }
             return instance;
         }
     }

     @Override
     public String getAccept() {
         return JsonObjectRequest.ACCEPT;
     }

 }

activity

Request<ServerBean> request = new JavaBeanRequest<ServerBean>(url, ServerBean.class);
CallServer.getInstance().add(this, request, callBack, , true, false, true);
