socket模塊如何在Python項目中使用?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
socket ssh
import socket import os server = socket.socket() server.bind(('localhost', 6969)) #綁定被監(jiān)聽端口 server.listen(5) #監(jiān)聽端口 while True: print("我要開始等電話了") conn, addr = server.accept() # 就是等待的意思 #conn就是客戶端連過來的時候,在服務器端為其生成的一個連接實例 print("電話來了%s"% [conn, addr]) while True: data = conn.recv(1024) if not data: print('client is lost.') break # res = os.popen(data).read() #popen就是打開命令執(zhí)行,read就是獲取結(jié)果 # with open('filename', 'r') as ret: #這兩行就 可以用過來傳輸文件了。 # data = ret.read() print('receive:',data) conn.send(data.upper()) server.close()
socket client 模塊
#! /usr/bin/env python # -*- coding:utf-8 -*- # Author Ian Ying # mail: kongqing.ying@yitu-inc.com import socket client = socket.socket() #聲明socket類型,同時生成socket鏈接對象 client.connect(('localhost',6969)) #localhost就是本機地址 while True: msg = input('input msg >>:').strip() if len(msg) == 0: continue #檢查msg的信息,防止無輸入信息 #client.send(b"Hello, world!") #發(fā)送信息 client.send(msg.encode('utf-8')) data = client.recv(1024) #默認接受1024字節(jié),就是1k # with open('filename', 'w') as ret: # 這兩行就 可以用過來傳輸文件了。 # ret = data.write() print(data.decode()) client.close() #關(guān)閉端口
防止粘包的socket_ssh.py
