Python 如何将send（）函数应用于套接字对象？

编辑：我使用不推荐的

apply（）

进行pickle漏洞攻击，用于安全竞赛

apply

似乎是使用pickle指令字符串调用方法的方式。不过，我很乐意知道更好的方法

我试图使用

apply（）

在

套接字上调用
send（）
方法。\u socketobject

，但收到一条奇怪的错误消息

In [130]: client
Out[130]: <socket._socketobject at 0x108d0bfa0>

In [131]: apply(socket._socketobject.send, (client, "stuff"))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-131-3f9b1f1de824> in <module>()
----> 1 apply(socket._socketobject.send, (client, "stuff"))

TypeError: 'member_descriptor' object is not callable

这就是我最初获得名为client的套接字对象的方式：

In [107]: import signal

In [108]: sock = socket.socket()

In [109]: sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

In [110]: sock.bind(('0.0.0.0', 1025))

In [111]: sock.listen(10)

In [112]: signal.signal(signal.SIGCHLD, signal.SIG_IGN)
Out[112]: 0
In [113]: client, addr = sock.accept()

感谢您的帮助

有趣的是，send（）属于function类型

不对

send

从其

\uuu get\uuu（）方法返回一个函数，因为它是一个函数。如果您想要得到要调用的实际函数，您将需要自己与描述符协议接口

>>> dir(socket._socketobject.send)
['__class__', '__delattr__', '__delete__', '__doc__', '__format__', '__get__', '__getattribute__', '__hash__', '__init__', '__name__', '__new__', '__objclass__', '__reduce__', '__reduce_ex__', '__repr__', '__set__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
>>> type(socket._socketobject.send)
<type 'member_descriptor'>

目录（socket.\u socketobject.send）
“UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU“，”集合“，”集合属性“，”大小属性“，”结构“，”子类钩子“]
>>>类型（socket.\u socketobject.send）

为什么要使用

apply

？自Python2.3.1以来，它一直被弃用<代码>应用已（非常）不推荐使用。2.这不是应该如何使用的请参见上面的编辑。除了我不应该使用它，因为它已经被弃用了之外，它应该如何使用呢？非常感谢你澄清这一点，我将不得不对它进行更深入的研究

>>> dir(socket._socketobject.send)
['__class__', '__delattr__', '__delete__', '__doc__', '__format__', '__get__', '__getattribute__', '__hash__', '__init__', '__name__', '__new__', '__objclass__', '__reduce__', '__reduce_ex__', '__repr__', '__set__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
>>> type(socket._socketobject.send)
<type 'member_descriptor'>
