ionic $ state不会触发套接字发射

Question

SELECT FROM_UNIXTIME(900 * FLOOR(UNIX_TIMESTAMP(timestamp)/900)) timestamp
     , MAX(CASE WHEN address = 1 THEN value END) temp 
     , MAX(CASE WHEN address = 2 THEN value END) rh 
     , MAX(CASE WHEN address = 3 THEN value END) co2 
  FROM historical
 WHERE register_type = 11 
 GROUP 
    BY timestamp;

不确定为什么我需要刷新然后只能看到已执行的emit。我使用$ state.go（'order'）来到这个页面。
