无法重载python socket.send

我确信您实际上并不需要它,而且还有其他方法来解决您的任务(不是子类化,而是真正的任务)。

如果您确实需要模拟对象,请使用代理对象:

from socket import socket


class PolySocket(object):
    def __init__(self, *p):
        print "PolySocket init"
        self._sock = socket(*p)

    def __getattr__(self, name):
        return getattr(self._sock, name)

    def sendall(self, *p):
        print "PolySocket sendall"
        return self._sock.sendall(*p)

    def send(self, *p):
        print "PolySocket send"
        return self._sock.send(*p)

    def connect(self, *p):
        print "connecting..."
        self._sock.connect(*p)
        print "connected"

HOST = "stackoverflow.com"
PORT = 80
readbuffer = ""

s = PolySocket()
s.connect((HOST, PORT))
s.send("a")
s.sendall("a")

输出结果如下:

% python foo.py
PolySocket init
connecting...
connected
PolySocket send
PolySocket sendall
