类中存在一个错误，不理解用python编写

Question

我想运行此代码时出现以下错误。我犯了一个错误，我不明白所有正常的地方

你认为错误在哪里

import socket,time
import thread
    class http():
        def __init__(self):
            self.socket = socket
            self.port = 5000
            self.buffsize = 1024
            self.listen = 5
            self._header = ("HTTP/1.1 200 OKrn"
                            "Content-Type: text/html; charset=utf-8rnrn")
        def _worker(self,socket,sleep):
            # Client connect for thread worker
            while True:
                time.sleep(sleep)
                client,address = socket.accept()
                data = client.recv(1024)
                if data:
                    client.send(self._header)
                    client.send(data)
                client.close()
        def httpHandler(self):
            # Create Socket For Connection
            try:
                self.socket.socket(socket.AF_INET,socket.SOCK_STREAM)
                self.socket.bind(('127.0.0.1',self.port))
                self.socket.listen(self.listen)
                self.socket.setblocking(False)
            except socket.error as error:
                print error
            finally:
                print "HTTP Server Running - 127.0.0.1:5000"
                self._worker(self.socket,1)
    if __name__ == "__main__":
        application = http()
        application.httpHandler()

当我想在终端上运行时，错误

但怎么能说有自我的问题呢？

HTTP Server Running - 127.0.0.1:5000
Traceback (most recent call last):
  File "/Users/batuhangoksu/http.py", line 44, in <module>
    application.httpHandler()
  File "/Users/batuhangoksu/http.py", line 40, in httpHandler
    self._worker(self.socket,1)
  File "/Users/batuhangoksu/http.py", line 22, in _worker
    client,address = socket.accept()
AttributeError: 'module' object has no attribute 'accept'

Answer 1

使用 self.socket ，而不是socket ：

            client,address = self.socket.accept()

socket是模块的名称。 self.socket是一个socket._socketobject，调用socket.socket返回的值。确实，有太多的东西叫做"套接字":)。我建议将self.socket更改为其他内容以帮助分离想法。

调用 socket.socket 时还需要保存返回值。目前，您有

self.socket = socket

将实例属性self.socket设置为模块socket。这没有用，因为您已经可以使用普通的旧socket访问该模块。相反，请使用类似

        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
