python - 属性错误: '_Helper' object has no attribute 'encode'

Question

当我输入 help 时，我将客户端连接到服务器，我收到 AttributeError: '_Helper' object has no attribute 'encode'

这是完整的输出

-:-:-:-:-:Server:-:-:-:-:-
Connection from: ('127.0.0.1', 58675)
Your Instruction: help
Traceback (most recent call last):
  File "serverback.py", line 36, in <module>
    msg = msg.encode("UTF-8")
AttributeError: '_Helper' object has no attribute 'encode'

这是我的Python脚本

#imports
import socket
import os
import sys
#Variables
port = int(sys.argv[1])

#Functions

def clear():
    os.system('cls' if os.name=='nt' else 'clear')

#Starting Server
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = socket.gethostname()
serversocket.bind((host, port))
serversocket.listen(1)

clear()
print("-:-:-:-:-:Py Server:-:-:-:-:-")
clientsocket, addr = serversocket.accept()
print("Connection from: " + str(addr))
while True:
    msg = input("Your Instruction: ")

    if msg == "help":
        clear()
        print("-+-+-+-+-+HELP+-+-+-+-+-")
        print("Test Connection: 'test'")

        input("\nPress ENTER to continue")
        clear()
        print("-:-:-:-:-:Py Server:-:-:-:-:-")

    else:
        msg = msg.encode("UTF-8")
        clientsocket.send(msg)
        msg = clientsocket.recv(4096)
        print(msg.decode("UTF-8"))

Answer 1

msg 是否由于某种原因未定义？在 Python3+ 中，输入应始终返回一个字符串，但由于某种原因，当满足 else 条件时，您的 msg 变量似乎不是字符串。您可以将 msg 显式转换为字符串。

else:
    msg = str(msg).encode("UTF-8")
    clientsocket.send(msg)
    msg = clientsocket.recv(4096)
    print(msg.decode("UTF-8"))
