我正在以低速率（30 / s）将消息发布到RabbitMQ。 如果在消息发布后关闭连接，则显示以下错误。
fatal error: concurrent map read and map write

我的代码：
func Publish(name string, body []byte) {
channel, err := connection.Channel()
defer channel.Close() // commenting out this does not cause any errors but too many channels are left.
err := channel.Publish("", name, false, false, amqp.Publishing{
DeliveryMode: amqp.Persistent,
ContentType: "text/plain",
Body: body,
})
util.HandlerError(err, "Could not publish message for mq : "+name)
}
有没有办法防止错误，但关闭通道？
