【Python】通讯循环与避免BUG

# 客户端
import socket
phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  # 1.获取socket对象
phone.connect(('127.0.0.1', 8080))  # 2.连接服务端端口
data = phone.recv(1024)  # 3.接收
while 1:
    msg = input()
    phone.send(msg.encode('utf-8'))  # 发送数据
    if not msg: continue           # 防止空内容bug
phone.close()  # 4.关闭

# 服务端
import socket
phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  # 1.获取socket对象
phone.bind(('127.0.0.1', 8080))  # 2.绑定服务端口
phone.listen(5)  # 3.等待连接
connect, client_addr = phone.accept()  # 4.建立连接并获得连接对象
while 1:
    try:
        data = connect.recv(1024)   # 5.接收数据
        if not data: break         # 防止客户端单方终止的Linux bug
    except ConnectionResetError:   # 防止客户端单方终止的windows bug
        break
    connect.send(data.upper())  # 发送数据
connect.close()  # 6. 关闭连接
phone.close()  # 7.关机


连续循环通讯

# 客户端
import socket
phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  # 1.获取socket对象
phone.connect(('127.0.0.1', 8080))  # 2.连接服务端端口
data = phone.recv(1024)  # 3.接收
while 1:  # 通信循环
    msg = input()
    phone.send(msg.encode('utf-8'))  # 发送数据
    if not msg: continue           # 防止空内容bug
phone.close()  # 4.关闭

# 服务端
import socket
phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
phone.bind(('127.0.0.1', 8080))
phone.listen(5)  # 当有1个客户端通信阻塞时,其他客户端会被挂起,上限是 5 个

while not close:  # 连接循环  可进行多次连接, 但每次只通信一个客户端, 排队服务..
    connect, client_addr = phone.accept()
    while not disconnect:  # 通信循环
        try:
            data = connect.recv(1024)
            if not data: break
        except ConnectionResetError:
            disconnect = 1
        connect.send(data.upper())
    connect.close()

phone.close()
