# coding=utf-8 import socket import sys from thread import * HOST = '' # Symbolic name meaning all available interfaces PORT = 8888 # Arbitrary non-privileged port # 创建对象 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) print 'Socket created' # 绑定IP端口,真正创建socket # Bind socket to local host and port try: s.bind((HOST, PORT)) # 如果创建 socket 函数失败,会抛出一个 socket.error 的异常,需要捕获 except socket.error, msg: print 'Bind failed. Error Code : ' + str(msg[0]) + ' Message ' + msg[1] sys.exit() print 'Socket bind complete' # 监听 # Start listening on socket s.listen(10) print 'Socket now listening' # 接受数据的方法 # Function for handling connections. This will be used to create threads def clientthread(conn): # Sending message to connected client conn.send('Welcome to the server. Type something and hit enter\n') # send only takes string # infinite loop so that function do not terminate and thread do not end. while True: # Receiving from client data = conn.recv(1024) reply = 'OK...' + data if not data: break conn.sendall(reply) # came out of loop conn.close() # 为每一个连接创建一个线程执行以上接受数据的方法 # now keep talking with the client while 1: # wait to accept a connection - blocking call conn, addr = s.accept() print 'Connected with ' + addr[0] + ':' + str(addr[1]) # 用普通tread一样,自己给方法传参就是了 # start new thread takes 1st argument as a function name to be run, second is the tuple of arguments to the function. start_new_thread(clientthread, (conn,)) s.close()
客服端(这是http客服端 改改就能和上面的一起用)
import socket # for sockets import sys # for exit try: # create an AF_INET, STREAM socket (TCP) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) except socket.error, msg: print 'Failed to create socket. Error code: ' + str(msg[0]) + ' , Error message : ' + msg[1] sys.exit(); print 'Socket Created' host = 'www.baidu.com' port = 8080 try: # 此方法可以通过域名获取IP remote_ip = socket.gethostbyname(host) except socket.gaierror: # could not resolve print 'Hostname could not be resolved. Exiting' sys.exit() print 'Ip address of ' + host + ' is ' + remote_ip # Connect to remote server/与远端ip 端口 连接 s.connect((remote_ip, port)) print 'Socket Connected to ' + host + ' on ip ' + remote_ip # Send some data to remote server/一串http的命令 message = "GET / HTTP/1.1\r\n\r\n" try: # Set the whole string//发送字符串 s.sendall(message) except socket.error: # Send failed print 'Send failed' sys.exit() print 'Message send successfully' # Now receive data//接受数据 reply = s.recv(4096) print reply # 聊天室类的 在连接后来个while 1 循环接受发送即可 s.close()
