获取响应中的JASON对象

 protected BaseRes parseJsonResponse(HttpResponse httpRes, Class clz) throws Exception {

 

// 处理JSON返回结果

String jsonStr = EntityUtils.toString(httpRes.getEntity());

StringBuilder sb = new StringBuilder();

String[] jsonItems = jsonStr.split(","); 

sb.append(" parseJsonResponse - start - " + "\n");

for (String string : jsonItems) {

sb.append("  " + string + "\n");

}

sb.append(" parseJsonResponse - end - " + "\n");

LogUtils.logi(LOG_TAG, "json str:" + sb.toString());

 

JSONObject jsonObject = new JSONObject(jsonStr);

 

// 取json中response节点中的字串

String responseStr = jsonObject.getString("response");

 

// 转换器

GsonBuilder builder = new GsonBuilder();

 

// 不转换没有 @Expose 注解的字段

builder.excludeFieldsWithoutExposeAnnotation();

Gson gson = builder.create();

 

// 从JSON串转成JAVA对象

BaseRes response = gson.fromJson(responseStr, clz);

jsonObject = null;

builder = null;

//added by edwar 2012-08-31 释放内存 --end

return response;
