    #循环读取删除消息直到队列空
    #receive message请求使用long polling方式，通过wait_seconds指定长轮询时间为3秒

    ## long polling 解析:
    ### 当队列中有消息时，请求立即返回；
    ### 当队列中没有消息时，请求在MNS服务器端挂3秒钟，在这期间，有消息写入队列，请求会立即返回消息，3秒后，请求返回队列没有消息；

    wait_seconds = 3
    # print "%sReceive And Delete Message From Queue%s\nQueueName:%s\nWaitSeconds:%s\n" % (10*"=", 10*"=", queue_name, wait_seconds)
    #读取消息
    try:
        recv_msg = my_queue.receive_message(wait_seconds)
        # print "Receive Message Succeed! ReceiptHandle:%s MessageBody:%s MessageID:%s" % (recv_msg.receipt_handle, recv_msg.message_body, recv_msg.message_id)

            print
            "Queue not exist, please create queue before receive message."
