Thrift：类型错误：getaddrinfo() 参数 1 必须是字符串或 None
您好，我正在尝试用 python 编写一个简单的 thrift 服务器（名为 PythonServer.py），使用单个方法返回用于学习目的的字符串。服务器代码如下。当我运行服务器时，Thrift 的 python 库中出现以下错误。有没有人遇到过这个问题并提出解决方法？
执行输出：

Hi I am trying to write a simple thrift server in python (named PythonServer.py) with a single method that returns a string for learning purposes. The server code is below. I am having the following errors in the Thrift's python libraries when I run the server. Has anyone experienced this problem and suggest a workaround?
The execution output:

您的问题是这一行：
当调用单个参数的
TSocket.TServerSocket时，该值被视为主机标识符，因此getaddrinfo()出现错误。要解决此问题，请将行更改为：
Your problem is the line:
When calling
TSocket.TServerSocketwhich a single argument, the value is treated as a host identifier, hence the error withgetaddrinfo().To fix that, change the line to:
