Python Pika basic_发布大型邮件时出现发布错误

Pika发布消息成功，其大小小于10k字节，当大小大于10k字节时失败

错误信息如下：

Error. Connection closed, and the message was never delivered.
Traceback (most recent call last):

    ret = test_mq.publish(test_str)

我建议您升级到pika 0.9.14。最新版本修复了几个相当严重的套接字错误；包括引起你问题的那个

您可以使用pip升级到0.9.14：

pip安装pika——升级

这是从0.9.14的“尚未完成”中提取的

Major issue with socket buffer refactor in 0.9.13 (#328) fixes by cooper6581 and Erik Andersson

作为替代方案，如果出于某种原因无法从0.9.13升级到0.9.14，可以尝试Python的一些替代RabbitMQ客户端

• -->code>pip安装amqp storm
• -->code>pip安装rabbitpy
• -->code>pip安装amqp
• --

  pip安装librabbitmq

• -->code>pip安装txamqp

--在RabbitMQ官方网站上提供了更全面的pika替代品列表。

感谢您提供的可行替代品列表。我想补充一点。当然，这并不是一个全面的列表。我主要是想给他提供一些类似皮卡的替代品，以防他无法使用。
