【问题描述】：

连接到我的 WebSocket 时，我在客户端连接后立即收到上述错误。

在客户端它看起来像这样：

WebSocket connection to 'ws://server-ip:1025/' failed: Error during WebSocket handshake: Invalid status line

我一直在尝试做的事情：

我关注this tutorial 创建了一个实时聊天（与 Django）。我使用的 chatserver.py 直接来自他们的文档：https://twistedmatrix.com/documents/current/_downloads/chatserver.py。其余的（jQuery 脚本等）与该教程中的一样。

【参考方案1】：

MyChat.lineReceived 将消息发送给每个连接的客户端包括本身。我希望这意味着它会将收到的所有标头回显给 WebSocket 客户端，这可能不是它所期望的。

您链接到的 ferritfarmer 教程通过将 MyChat 的工厂包装在 WebsocketResource 中来处理此问题，这是对您直接从普通 Twisted 示例链接到的 chatserver.py 的修改。

我相信 WebsocketResource 来自教程链接到的 Twisted 的特定开发分支。不幸的是，该分支似乎停滞不前。我听说Autobahn 的 WebSocket 实现是个不错的选择。
