Python套接字无效参数

Question

一些信息： 操作系统：Windows 10（已安装WSL2） IDE:Emacs

我正在一个使用python套接字库的项目中工作

我创建了一个类来组织服务器进程，在该服务器中我有一个方法“requestConnection”，当我调用该方法时，它会给我一个错误“Errno 22[invalid argument]”

以下是错误：

Traceback (most recent call last):
  File "SocketChat.py", line 4, in <module>
    servidor.requestConnection()
  File "/mnt/c/Users/Mauro/Development/Projects/SocketChat/server.py", line 16, in requestConnection
    self.con = self.server_socket.accept()
  File "/usr/lib/python3.8/socket.py", line 292, in accept
    fd, addr = self._accept()
OSError: [Errno 22] Invalid argument

以下是主要代码：

from server import Server, Chat

servidor = Server('127.0.0.1', '5000')
servidor.requestConnection()

chat = Chat(servidor.receiveMsg())

以下是课程：

import socket

class Server:
    def __init__(self, host, port):
        self.host = host
        self.port = port
        self.addr = (host, port)
        self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)


    def shutDown(self):
        self.server_socket.close()


    def requestConnection(self):
        self.con = self.server_socket.accept()


    def receiveMsg(self):
        receive = self.con.recv(1024)
        return str(receive)


class Chat:
    def __init__(msg):
        self.msg = msg
        pass


    def newMsg(self):
        print(f"new message: {self.msg.decode()}")
        pass

如果你知道如何解决这个问题，请给我答案

Answer 1

尝试将端口号作为整数而不是字符串传递：

from server import Server, Chat

servidor = Server('127.0.0.1', 5000)
