python的socket

记录：备忘录。
1.socket

from socket import *

#1.创建socket
serverSocket = socket(AF_INET, SOCK_STREAM)
#2.绑定端口和地址
addrInfo = ("192.168.109.1",8082)
serverSocket.bind(addrInfo)
#3.设置为非阻塞socket
serverSocket.setblocking(False)
#4.设置监听参数
serverSocket.listen(50)
#5.定义list保存已经连接的客户端信息
clientAddrList = []

#6.循环
while True:
    try:
        #7.等待连接
        clientSocket,clientAddr = serverSocket.accept()
    except:
        pass
    else:
        print("新增一个客户端：%s"%str(clientAddr))
        clientSocket.setblocking(False)
        # 8.把新增连接加入到list中
        clientAddrList.append((clientSocket,clientAddr))
    # 9.遍历socket列表
    for clientSocket,clientAddr in clientAddrList:
        try:
            recvData = clientSocket.recv(1024)
        except:
            pass
        #10.接收到数据并处理
        else:
            if len(recvData) >0:
                print("%s:%s" % (str(clientAddr), recvData))
            # 11.客户端断开连接
            else:
                clientSocket.close()
                clientAddrList.remove((clientSocket, clientAddr))
                print("%s 下线" % str(clientAddr))

2.socket

import select
import socket
import sys

#1.创建socket
serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#2.绑定地址
serverSocket.bind(('', 8096))
#3.设置监听参数
serverSocket.listen(10)
#4.入参设置
inputs = [serverSocket, sys.stdin]
runFlag = True
while True:
    #5.调用select函数
    readable, writeable, exceptional = select.select(inputs, [], [])
    #6.遍历已读数据
    for sock in readable:
        # 7.监听新的连接
        if sock == serverSocket:
            conn, addr = serverSocket.accept()
            inputs.append(conn)

        # 8.监听键盘输入
        elif sock == sys.stdin:
            cmd = sys.stdin.readline()
            runFlag = False
            break

        # 9.有数据到达
        else:
            # 10.读取客户端发送的数据
            data = sock.recv(1024)
            if data:
                #11.打印接收的数据
                print(str(data, encoding="gbk"))
                # 12.向客户端发送数据
                sock.send("服务端已经接收到数据.".encode("gbk"))
            else:
                # 13.移除select监听的socket
                inputs.remove(sock)
                sock.close()
    # 退出
    if not runFlag:
        break
serverSocket.close()
