python如何使用socket获得点对点的信息

python通过socket获得点对点的信息

import socket

print "Creating socket...",
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "done."

print "Looking up port number...",
port = socket.getservbyname('http', 'tcp')
print "done."

print "Connecting to remote host on port %d..." % port,
s.connect(("www.75271.com", port))
print "done."

print "Connected from", s.getsockname()
print "Connected to", s.getpeername()

返回结果如下：

Creating socket... done.
Looking up port number... done.
Connecting to remote host on port 80... done.
Connected from ('127.0.0.1', 51475)
Connected to ('116.255.236.107', 80)
