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 1 == 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", "123");
            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, 0, true, false, true);
