  1. let socketOpen = false
  2. let socketMsgQueue = []

  5. })
  7. wx.onSocketOpen(function(res) {
  8.   socketOpen = true
  9.   for (let i = 0; i < socketMsgQueue.length; i++){
  10.     sendSocketMessage(socketMsgQueue[i])
  11.   }
  12.   socketMsgQueue = []
  13. })
  15. function sendSocketMessage(msg) {
  16.   if (socketOpen) {
  17.     wx.sendSocketMessage({
  18.       data:msg
  19.     })
  20.   } else {
  21.     socketMsgQueue.push(msg)
