请求（where和where_X二选一）：
{你的接口域名}/?s=App.SuperTable.FreeAF&model_name=article&op_fun=SUM&op_field=view_times&group_filed=title&where=[["id",">",0]]&database=super&app_key={你的app_key}&sign={动态签名}

请求（where和where_X二选一）：

返回：
{
    "ret": 200,
    "data": {

示例2-附加更多选择字段select_more：
请求：
{你的接口域名}/?s=App.SuperTable.FreeAF&model_name=article&op_fun=SUM&op_field=view_times&group_filed=title&where=[["id",">",0]]&select_more=post_time,state@COUNT&database=super&app_key={你的app_key}&sign={动态签名}

上面查询相当于：SELECT post_time, COUNT(state) AS state_AT_COUNT, title, SUM(view_times) AS total_num FROM pa_article_tbl WHERE AND (id > 0) GROUP BY title ORDER BY total_num ASC LIMIT 0,10

返回：
{

                "state_AT_COUNT": "1", // 对应参数：select_more=state@COUNT
                "title": "这是一篇文章标题",
                "total_num": "100"
            },
