【学习笔记】python 简单创建新建一个网络客户端,并返回相关的信息
#导入socket包 import socket #使用socket.socket创建socket连接 #AF_INET表示通信类型,与IPv4对应 #SOCK_STREAM对应TCP通信 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') #tuple print('connecting to remote host on port %d...'%port) s.connect(('www.baidu.com',port)) print('done') #返回本地IP和端口号,返回远程机器IP和端口号 print(s.getsockname()) print(s.getpeername())
