Python 类型错误 : an integer is required while working with Sockets

Question

研究:

Getting a "TypeError: an integer is required" in my script

https://github.com/faucamp/python-gsmmodem/issues/39

https://docs.python.org/2/howto/sockets.html

这是我完整的错误输出:

Traceback (most recent call last):
File "/home/promitheas/Desktop/virus/socket1/socket1.py", line 20, in <module>
createSocket()
File "/home/promitheas/Desktop/virus/socket1/socket1.py", line 15, in    createSocket
ServerSock.bind((socket.gethostname(), servPort))
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
TypeError: an integer is required

代码:

import socket

# Acquiring the local public IP address
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(('8.8.8.8', 0))

# Defining some variables
servIpAddr = s.getsockname()[0]
servPort = ''
while ((len(servPort) < 4)): # and (len(servPort) > 65535)
    servPort = raw_input("Enter server port. Must be at least 4     digits.\n> ")

# Creating a socket to wait for a connection
def createSocket():
    ServerSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    ServerSock.bind((socket.gethostname(), servPort)) # This is where the error occurs
    ServerSock.listen(5)
    (clientsocket, address) = ServerSock.accept()

if __name__ == "__main__":
    createSocket()

我不确定是否还有其他错误，但我真的被这个错误难住了。请询问您是否需要任何其他信息，在此先感谢您!

看起来地址元组的第二个元素需要是一个整数。来自文档:

A pair (host, port) is used for the AF_INET address family, where host is a string representing either a hostname in Internet domain notation like 'daring.cwi.nl' or an IPv4 address like '100.50.200.5', and port is an integer.

在 bind 中使用它之前，尝试将 servPort 转换为整数。

servPort = ''
while ((len(servPort) < 4)): # and (len(servPort) > 65535)
    servPort = raw_input("Enter server port. Must be at least 4     digits.\n> ")
servPort = int(servPort)
