一些给后来的人的建议 about go-socket.io-client HOT 3 OPEN

func (c *clientConn) pingLoop() {
	lastPing := time.Now()
	lastTry := lastPing
	for {
		now := time.Now()
		pingDiff := now.Sub(lastPing)
		tryDiff := now.Sub(lastTry)
		select {
		case ok := <-c.pingChan:
			if !ok {
				return
			}
			fmt.Println("ping chan receive data")
			lastPing = time.Now()
			lastTry = lastPing
		case <-time.After(c.pingInterval - tryDiff):
			fmt.Println("ping again")
			c.writerLocker.Lock()
			if w, _ := c.getCurrent().NextWriter(message.MessageText, parser.PING); w != nil {
				writer := newConnWriter(w, &c.writerLocker)
				writer.Close()
			} else {
				c.writerLocker.Unlock()
			}
			lastTry = time.Now()
		}
		case <-time.After(c.pingTimeout - pingDiff):
			c.Close()
			return
		}
	}
}
