我试着用RabbitMQ发送和接收消息。我没有计算机科学背景，我使用的术语不可能很准确。
我尝试复制教程文件：当提交我的html表单时，我的python脚本（cgi）将消息提交到队列

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
        channel = connection.channel()
        channel.queue_declare(queue='task_queue', durable=True)
        message = PN
        channel.basic_publish(exchange='',
                              routing_key='task_queue',
                              body=message,
                              properties=pika.BasicProperties(
                                 delivery_mode = 2, # make message persistent
                              ))
        connection.close()

我的接收器正在运行：

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()
channel.queue_declare(queue='task_queue', durable=True)
print(' [*] Waiting for messages. To exit press CTRL+C')

def callback(ch, method, properties, body):
    print(" [x] Received Project %r" % body)
    #ch.basic_ack(delivery_tag = method.delivery_tag) 
    if not (os.path.isfile(js_path)):
        print (' [*] ERROR files missing ')
        #ch.basic_ack(delivery_tag = method.delivery_tag)
        return
    p= subprocess.Popen(run a subprocess here)
    p.wait()

    print (' [*] Temporary Files removed')
    print(" [*] Waiting for messages. To exit press CTRL+C")

channel.basic_qos(prefetch_count=1)
channel.basic_consume(callback,queue='task_queue',no_ack=True)
channel.start_consuming()

它管理的大部分时间，但随机崩溃与以下错误：
