代码片段如下

    wx.request({
      url: api.my_service_url,  // 后端路径
      data: that.data.request_data,  // code
      method: "POST",
      success: function (res) {
        console.log('getMyserviceData 请求成功')
        wx.hideLoading();
        console.log(res.data)
        var resData = res.data
        if(typeof resData != "object"){
          log.info('getMyserviceData typeof res:',typeof resData)
          var resData = JSON.parse(res.data);
        }
        log.info('getMyserviceData res:',resData)
        log.info('getMyserviceData status:',resData.status)
        log.info('getMyserviceData[status]:',resData["status"])
        log.error('getMyserviceData 500 error res.data.service_list:',resData.service_list)

      },
      fail: function (res) {
        log.error('getMyserviceData fail error:',res.data)

        console.log('getMyserviceData 请求失败')
        that.showInfo('内部服务错误！');
      }
    })

关键数据res.data的console打印如下：

{"status": 1,"totalpage": "26","service_list":[{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/17 13:13:38","content": "XXXXX"},{"group_id": "2","article_id": "376379","user_name": "XX","add_time": "2020/9/17 12:45:24","content": "XX"},{"group_id": "2","article_id": "376379","user_name": "XX","add_time": "2020/9/17 12:20:26","content": "XXXX"},{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/17 12:16:35","content": "XXXXXX"},{"group_id": "2","article_id": "376379","user_name": "XX","add_time": "2020/9/17 11:42:55","content": "XXXX"},{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/17 11:08:09","content": "XXXXXX"},{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/17 10:12:54","content": "XXXX"},{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/16 12:57:58","content": "XXXXXXXXX"},{"group_id": "2","article_id": "376379","user_name": "XXX","add_time": "2020/9/16 12:19:49","content": "XXXXX"},{"group_id": "2","article_id": "376379","user_name": "XX","add_time": "2020/9/15 15:46:17","content": "X"}]}

log打印日志如下：

[13:30:00]  getMyserviceData status: <Undefined>


[13:30:00]  getMyserviceData status: <Undefined>



[13:30:00]  getMyserviceData 500 error status: <Undefined>

res.data有数据，并且确实为object类型，如何解析其中的status和service_list值？
