【问题描述】：

我遇到了 Pika 出现超时错误的问题。相同的代码（如下）在其他环境中运行良好，但在这个环境中失败。

connection = pika.BlockingConnection(pika.ConnectionParameters(host=host))

【参考方案1】：

查看 RabbitMQ 日志，您可能需要提供登录凭据：

pika.BlockingConnection(pika.ConnectionParameters(host, port=port, virtual_host=vhost, credentials=pika.credentials.PlainCredentials(username, password)))
