问题描述
我有一个使用autobahnWebSocket框架实现的WebSocket服务器。WebSocket服务器在运行该程序时运行良好。但是，如果我使用twistd服务器运行器通过创建TAC文件作为扭曲服务来运行此程序，当任何客户端尝试建立连接并且握手失败时，我在服务器中得到以下错误。

推荐答案
今天我发现了同样的问题。 您应该将txaio降级到版本1.1.0
这是我的PIP清单 高速公路(0.10.9) AutobahnestSuite(0.7.3) 扭曲(15.4.0) Txaio(1.1.0) Zope.interface(4.1.3)
这篇关于使用tac文件运行twistd时出现Autobahn WebSocket问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持编程学习网！
