Question

我在使用python从服务器获取数据时遇到了困难。每当我尝试访问我的测试html文件时，我的浏览器上都会收到Errno 9错误的文件描述符和“连接已重置”消息。代码如下：

#import socket module
from socket import *
serverSocket = socket(AF_INET, SOCK_STREAM)
serverPort = 12000
#Prepare a sever socket
serverSocket.bind(("", serverPort))
serverSocket.listen(1)


while True:
    #Establish the connection
    print 'Ready to serve...'
    connectionSocket, addr = serverSocket.accept()#Accepts a TCP client    connection, waiting until connection arrives
    print 'Required connection', addr
    try:

        message = connectionSocket.recv(64)
        filename = message.split()[1]
        f = open(filename[1:])
        outputdata = f.read()

        #Send one HTTP header line into socket
        connectionSocket.send('HTTP/1.0 200 OK\r\n\r\n')


        #Send the content of the requested file to the client

        for i in range(0, len(outputdata)):
            connectionSocket.send(outputdata[i])
        connectionSocket.close() 

    except IOError:
        #Send response message for file not found
        connectionSocket.send('404 Not Found!')
        #Close client socket
        connectionSocket.close()
        serverSocket.close()

我不知道为什么我会收到此错误。我已经尝试从outputdata for循环外部移除关闭，这也不起作用。我尝试更改服务器端口，并以不同的顺序关闭套接字和服务器。

完整的引用是：

Traceback (most recent call last):
  File "UDPServer.py", line 13, in <module>
    connectionSocket, addr = serverSocket.accept()#Accepts a TCP client   connection, waiting until connection arrives
  File "C:\Anaconda\lib\socket.py", line 202, in accept
    sock, addr = self._sock.accept()
  File "C:\Anaconda\lib\socket.py", line 170, in _dummy
    raise error(EBADF, 'Bad file descriptor')
socket.error: [Errno 9] Bad file descriptor

关闭后，您无法使用套接字。 socket.close()的{{3}}说：

套接字对象的所有未来操作都将失败。

您可以在循环中创建一个新套接字。

errno 9坏文件描述符，基本python服务器套接字
