SOCKET 的簡單使用

• server端：

    import socket
    so = socket.socket() #創(chuàng)建套接字
    so.setsockopt(socket.SOL_SOCKET, soket.SO_REUSEADDR, 1) #防止端口被長期占用
    
    so.bind( ("IP",端口)) #綁定你要開啟服務(wù)的端口
    so.listen()
    connet ,addr = so.accept() #等待鏈接后重新分配一個(gè)端口
    # addr 為請求方的地址和端口
    # connet 為重新分配的套接字笋籽，為本次連接的客戶端服務(wù)
    
    ret = connet.recv(1024) #等待接收字節(jié)數(shù)據(jù)
    # 處理你的數(shù)據(jù)
    print(ret)
    
    connet.close() #關(guān)閉本次連接
    
    so.close() #關(guān)閉本程序連接
  

• client端：

    import socket
    
    so = socket.socket() # 創(chuàng)建套接字
    so.connect(("IP", 端口)) # 連接要發(fā)送的地址和端口
    so.send(b"字節(jié)數(shù)據(jù)")    # 發(fā)送字節(jié)數(shù)據(jù)
    so.close()  # 關(guān)閉本次連接
  

• 作業(yè):

    1. 循環(huán)對話聊天
    2. server： #接收時(shí)間戳?xí)r間劝篷，轉(zhuǎn)換成格式化時(shí)間\
       client： 每10秒鐘發(fā)送一次時(shí)間戳
  

• 循環(huán)聊天：

    1、server端：
    
    import socket
  
    Addr = "127.0.0.1"
    Port = 9000
    
    so = socket.socket()
    so.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    so.bind((Addr, Port))
    so.listen()
    connect, addr = so.accept()
    print(str(addr) + "已經(jīng)連接")
    while True:
        ret = connect.recv(1024).decode("utf-8")
        if ret == "bye":
            break
        else:
            print(ret)
            info = input(">>>輸入要發(fā)送的內(nèi)容：")
            connect.send(bytes(info, encoding="utf-8"))
    
    connect.close()
    so.close()
    
    
    
    2、client端：
    # coding:UTF-8
    import socket
    
    Addr = "127.0.0.1"
    Port = 9000
    
    so = socket.socket()
    so.connect((Addr, Port))
    while True:
        info = input(">>>輸入你要發(fā)送的內(nèi)容：")
        so.send(bytes(info, encoding="utf-8"))
        ret = so.recv(1024).decode("utf-8")
        if ret == "bye":
            print("斷開連接")
            break
        print(ret)
    
    so.close()
  

• 定時(shí)時(shí)間轉(zhuǎn)換：

    1舒萎、server端：
    import socket
    import time
    Addr = "127.0.0.1"
    Port = 9000
    
    so = socket.socket()
    so.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    so.bind((Addr, Port))
    so.listen()
    connect, addr = so.accept()
    
    while True:
        ret = connect.recv(1024).decode("utf-8")
        ret = time.localtime(float(ret))
        print(time.strftime("%Y-%m-%d %H:%M:%S", ret))
    
    
    connect.close()
    so.close()
    
    
    2、client端:
    # coding:UTF-8
    import socket
    import time
    Addr = "127.0.0.1"
    Port = 9000
    
    so = socket.socket()
    so.connect((Addr, Port))
    
    while True:
        time.sleep(10)
        so.send(bytes(str(time.time()), encoding="utf-8"))
    
    so.close()
