皮卡：如何在生产者和经纪人之间建立理想的联系？

Question

问题的根源

我的扭曲必须不时向rabbitmq发布消息。但在测试过程中，出现了以下问题：

1. ConnectionClosed: timeout

2. ConnectionClosed: (-1, "ConnectionResetError(54, 'Connection reset by peer')")

3. ChannelClosed

4. mq = MessageQueue() mq.declare_direct_exchange("exchange") mq.publish_message(message)

要求

此连接需要满足以下要求：

1. 不会断开连接。

2. 断开连接时可以自动重新连接。

调用代码

class MessageQueue():
channel = None

def __init__(self):
    if not MessageQueue.channel:
        credentials = pika.PlainCredentials("name", "password")
        conn_params = pika.ConnectionParameters(ip,
                                                credentials = credentials,
                                                heartbeat=10)
        conn_broker = pika.BlockingConnection(conn_params)

        MessageQueue.channel = conn_broker.channel()

    self.exchange_declared = False
    self.exchange_name = ""

def declare_direct_exchange(self, exchange_name):
    self.exchange_name = exchange_name
    self.channel.exchange_declare(exchange=exchange_name,
                                  exchange_type="direct",
                                  passive=False,
                                  durable=True,
                                  auto_delete=False)
    self.exchange_declared = True

def publish_message(self, message=""):
    if not self.exchange_declared:
        raise ExchangeNotDeclaredException("Exchange must be declared "
                                           "before publish messages.")
    msg_props = pika.BasicProperties()
    msg_props.content_type = "text/plain"

    self.channel.basic_publish(body=message,
                               exchange=self.exchange_name,
                               properties=msg_props,
                               routing_key="hola")

MessageQueue Class

我将通道设置为类属性导致以后创建的mq实例不必重新创建连接。

var test = [ '/', '/login', '//', '/login/login' ];

var reForFail = /(\/(?:login)?)\1$/;
var reForMatch = /\/(?:login)?$/;

console.log(test.map(e => !reForFail.test(e) && reForMatch.test(e)));
