The socket cannot be reconnected after the applet background is hidden

The socket cannot be reconnected after the applet background is hidden

• Event parameters of the fail callback function when connecting:connectSocket:fail:jsapi has no permission,event=createSocketTask,runningState=suspend,permissionMsg=permission ok,detail=network api interrupted in suspend state
• Cause of the error: It takes time to switch the foreground in the background of the applet. This error indicates that the applet is not in the foreground and cannot be connected when connected
• Solution: Use recursion in the fail callback function to continuously reconnect until it succeeds
• Note: when recursive, the time difference should be set

fail: function (e) {
    console.log('connect fail', e)
    setTimeout(() => {
        reconnect()  // 重连函数
    }, 300)
}
