使用 bunny,如何在连接到现有队列时设置 x-max-length

Using bunny, how to set x-max-length when connecting to existing queue

我有以下 ruby 函数连接到一个 max_length 值为 10000

的现有兔子队列
  def self.send(settings, event_str)
    conn = Bunny.new(
        hostname: settings['host'],
        username: settings['user'],
        password: settings['password'],
        virtual_host: settings['virtual_host']
    )
    conn.start
    ch = conn.create_channel
    q = ch.queue(
        settings['queue'],
        durable: true,
        auto_delete: false,
        x_max_length: 10000
    )
    ch.default_exchange.publish(event_str, :routing_key => q.name)
  end

调用时,返回此错误:

PRECONDITION_FAILED - inequivalent arg 'x-max-length' for queue 'event_queue' in vhost '/sensu': received none but current is the value '100000' of type 'signedint'

兔子版本:2.0.1 Ruby版本:2.3.1

我尝试了各种参数 ch.queue 但找不到设置最大队列长度值的方法。

欢迎提出建议。

看起来诀窍是将 arguments 哈希设置为 ch.queue

的参数
    q = ch.queue(
        settings['queue'],
        durable: true,
        auto_delete: false,
        :arguments => { 'x-max-length' => settings['queue_length'].to_i }
    )
