Sockets python中的套接字使用

我想在两台机器之间创建一个聊天程序。我使用的是IP地址为192.168.0.5的机器一，我可以成功地向机器二192.168.0.2发送消息，然后从机器二向机器一发送响应消息

但是，我在任何一台机器的第二次发送尝试中遇到了一个问题（注意，在第二次发送之前，我等待来自初始发送的响应），声称IP地址已在使用中或连接被拒绝，如何更改此设置，以便发送定义数量的选择

我知道下面的代码不是发送和接收多条消息的最有效方式，这可能是for循环的一些描述。例如，范围为（0,5）的sendAndRecieve的

这两台机器使用以太网电缆通过交换机连接，代码同时运行

机器1代码：

#Sending first message

host = "192.168.0.5"
port = 4446
from socket import *
s = socket(AF_INET, SOCK_STREAM)
s.bind((host,port))
s.listen(1)
print("listening")
q,addr = s.accept(1024)
data = "This is the first message I am sending"
data = data.encode("utf-8")
q.send(data)
s.close

#Recieving response message 1

while True:
    try:
        host = "192.168.0.2"
        port = 4446
        from socket import*
        s = socket(AF_INET, SOCK_STREAM)
        s.connect((host,port))
        msg = s.recv(1024)
        msg = msg.decode("utf-8")
        print(msg)
        s.close()
    except:
        pass

#Sending second message this is where the problem happens

host = "192.168.0.5"
port = 4446
from socket import *
s = socket(AF_INET, SOCK_STREAM)
s.bind((host,port))
s.listen(1)
print("listening")
q,addr = s.accept(1024)
data = "This is the first message I am sending"
data = data.encode("utf-8")
q.send(data)
s.close

机器2代码：

#Recieving message 1

while True:
    try:
        host = "192.168.0.5"
        port = 4446
        from socket import*
        s = socket(AF_INET, SOCK_STREAM)
        s.connect((host,port))
        msg = s.recv(1024)
        msg = msg.decode("utf-8")
        print(msg)
        s.close()
    except:
        pass

#Sending first message

host = "192.168.0.2"
port = 4446
from socket import *
s = socket(AF_INET, SOCK_STREAM)
s.bind((host,port))
s.listen(1)
print("listening")
q,addr = s.accept(1024)
data = "This is the first message I am sending"
data = data.encode("utf-8")
q.send(data)
s.close

#Recieving response message 1 this is where the problem happens

while True:
    try:
        host = "192.168.0.25"
        port = 4446
        from socket import*
        s = socket(AF_INET, SOCK_STREAM)
        s.connect((host,port))
        msg = s.recv(1024)
        msg = msg.decode("utf-8")
        print(msg)
        s.close()
    except:
        pass

通读您的代码，我看不出机器2的while循环如何停止尝试从机器1接收数据（循环中没有中断，除非遇到错误）。在机器2第一次连接后，机器1会继续运行，但当机器2尝试连接到机器1时，会尝试连接到机器2。这可能是您看到的错误的原因，也是您只看到发送/接收的第一条消息的原因
