Question

鉴于此部分代码，当按Ctrl + C时，程序返回错误“name'sock'未定义。”。我想这是正常的，因为sock.close()在课堂之外，但我应该怎么做才能阻止它？

在我的情况下，它是关于一个客户端，而不是服务器，要求关闭套接字。

import socket

class something(object):
    def connect(self):
        self.sock = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
        self.sock.connect((self.tcp_ip, self.tcp_port))
        # etc.

if __name__ == '__main__':
    try:
        app = something()
        app.connect()
    except KeyboardInterrupt:
        pass
    finally:
        sock.close()

Answer 1

我觉得这应该有用

import socket
class something(object):
    def __init__(self):
        self.sock = None

    def connect(self):
        self.sock = socket.socket( socket.AF_INET, socket.SOCK_STREAM)
        self.sock.connect(('127.0.0.1', 12397))
        self.sock.recv(1024)

    def close(self):
        self.sock.close()

if __name__ == '__main__':
    try:
        sk = something()
        sk.connect()
    except KeyboardInterrupt:
        pass
    finally:
        sk.close()
        print "Socket Closed"

Answer 2

试试这个。

if __name__ == '__main__':
    try:
        foo = something()
        foo.connect()
    except KeyboardInterrupt:
        pass
    finally:
        foo.sock.close()

除了KeyboardInterrupt之外，如何正常关闭带有sock.close（）的套接字：在类之外
