多网络套接字python

我正在创建一个python脚本，它侦听多个端口（在portslist中定义），当有人连接到其中任何一个端口时，会向他们发送一条“hello”消息。目前，下面的代码为端口列表中的所有端口创建套接字，但只向最后一个端口上的通信发送消息

谢谢

servers = []
for port in portlist:
    datasocket = ("0.0.0.0", port)

    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server.bind(datasocket)
    server.listen(5)

    servers.append(server)


while True:
ready_server = select.select(servers, [], [])


for s in ready_server:
        connection, address = server.accept()
        print str(address) + " has connected!\n"
        msg ="hello\n"
        connection.send(msg)
        connection.close()

当

select.select

返回时，

ready\u server

将是如下列表：

因此，ready_server中s的
将迭代这些列表，而不是套接字

此外，该循环中的
server.accept（）
并不引用任何循环变量，而是引用上一个循环中的
server

试试这个：

servers = []
for port in portlist:
    datasocket = ("0.0.0.0", port)

    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server.bind(datasocket)
    server.listen(5)

    servers.append(server)


while True:
    # unpack the returned list
    ready_server, _, _ = select.select(servers, [], [])


    for s in ready_server:
        # use s.accept instead of server.accept
        connection, address = s.accept()
        print str(address) + " has connected!\n"
        msg ="hello\n"
        connection.send(msg)
        connection.close()

首先，您在
while
循环下的缩进不好
