一：官方文档：

http://docs.python.org/py3k/library/socket.html

socket — Low-level networking interface

二：example

Server start:

F:\workspace_android\test\com\nagat\socket>Server.py
listen:...............
host: localhost ,post: 12345
wait.................
Connected by ('127.0.0.1', 50710)
其他数据：fs
Connected by ('127.0.0.1', 50711)
数据:hi

Client:

F:\workspace_android\test\com\nagat\socket>Client.py fs
from server to client： 其他数据：fs

F:\workspace_android\test\com\nagat\socket>Client.py hi
from server to client： 你好，世界

 

三：example code

server：

import socketHOST = 'localhost'                 # Symbolic name meaning all available interfacesPORT = 12345              # Arbitrary non-privileged ports = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.bind((HOST, PORT))s.listen(1)print("listen:............... ")print("host:",HOST,",post:",PORT)print("wait.................")while 1:    conn, addr = s.accept()    print ('Connected by', addr)    while 1:        data = conn.recv(1024)#        print(repr(data))#        print(str(data,"utf-8"))        if not data: break                if  data == bytes("hi","utf-8"):            print("数据:"+str(data,"utf-8"))            conn.sendall(bytes("你好，世界","utf-8"))        else :            print("其他数据："+str(data,"utf-8"))            conn.sendall(bytes("其他数据："+str(data,"utf-8"),"utf-8"))    conn.close()

 

Client：

import socket,sys#print(sys.argv)#print(sys.argv[1])HOST = 'localhost'    # The remote hostPORT = 12345              # The same port as used by the servers = socket.socket(socket.AF_INET, socket.SOCK_STREAM)s.connect((HOST, PORT))s.sendall(bytes(sys.argv[1],"utf-8"))data = s.recv(1024)s.close()print('from server to client：', str(data,"utf-8"))

四：除了字符串还能发送别的不？
