Python套接字服务器：处理输入

我希望通过一个无法发送RESTful消息的软件来控制Phillips hue lights，因此我尝试编写一个中间件，它将解释TCP消息，并将适当的请求传递给灯泡。套接字服务器来自我在BinaryTides上找到的一个示例

我对Phillips的所有东西都使用qhue，但是我的问题是python对消息的解释。当我启动socket服务器并使用netcat从另一台笔记本电脑连接到它时，我似乎无法让它激活所需的颜色变化

输入红色或绿色应该会导致qhue消息被发送，但我总是以“未知命令”的结果结束

更新：

我已经编写了一个简单的脚本，它基于

raw\u input

执行相同的操作，可以根据需要工作。因此，问题似乎在于套接字服务器读取和存储数据的方式。（以下文字有效）

见线程。尝试

=

而不是

is

，这是一个非常有用的链接。然而不幸的是，用

=

替换

is

会产生相同的结果。

打印数据

行说了什么？
