bug
在json2bean中如果不进行转换 if(bean instanceof HttpLogin){，将调用的市父类的Json2Me?
此并非最好的解决办法，应该用官方的json.toobject
package com.xx.app.inspector.api; import android.content.Context; import com.lidroid.xutils.exception.HttpException; import com.lidroid.xutils.http.ResponseInfo; import com.lidroid.xutils.http.callback.RequestCallBack; import com.xx.app.inspector.model.Http; import com.xx.app.inspector.model.HttpLogin; import com.xx.app.inspector.utils.LogUtils; import org.json.JSONException; import org.json.JSONObject;
public class HttpCallBack<T extends Http> extends RequestCallBack<String> { private Context mContext; public HttpCallBack(){} public HttpCallBack(Context context){ this.mContext = context; } @Override public void onSuccess(ResponseInfo<String> responseInfo) { } @Override public void onFailure(HttpException e, String s) { } public T json2Bean(String result,T bean){ try { JSONObject json = new JSONObject(result); if(bean instanceof HttpLogin){ HttpLogin h= (HttpLogin)bean; h.json2Me(json); }else{ bean.Json2Me(json); } return bean; } catch (JSONException e) { e.printStackTrace(); } return null; } }
public class HttpLogin extends Http { private final String TAG = "HttpLogin"; public String userName; public Long userId; public Token token; public void json2Me(JSONObject jsonObj) throws JSONException{ super.Json2Me(jsonObj); if(this.status == STATUS_SUCCESS){ JSONObject body = jsonObj.getJSONObject("body"); userName = body.getString("userName"); userId = body.getLong("userId"); LogUtils.d(TAG,"==="+userName); token= new Token(); token.json2Me(body.getJSONObject("token")); } } }
public class Http { /** 业务请求结果：成功*/ public static final int STATUS_SUCCESS = 0; /** 业务请求结果：错误*/ public static final int STATUS_ERROR = 1; public Integer status; public Integer code; public void Json2Me(JSONObject jsonObj) throws JSONException{ JSONObject obj = jsonObj.getJSONObject("header"); status = (Integer)obj.get("status"); code = getInteger(obj,"status"); code = getInteger(obj,"code"); } protected Integer getInteger(JSONObject obj,String key) throws JSONException{ return obj.isNull(key)?null:obj.getInt(key); } protected Long getLong(JSONObject obj,String key) throws JSONException{ return obj.isNull(key)?null:obj.getLong(key); } }
