在 Python 中，我们可以使用 Socket 的 SO_BROADCAST 选项来启用广播功能。以下是一个示例，展示了如何使用广播发送消息：import socket# 创建 Socketsock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)# 启用广播sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)# 广播消息message = b"Hello, ...
importsocket# 创建一个UDP Socketsock=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)# 设置Socket的广播选项sock.setsockopt(socket.SOL_SOCKET,socket.SO_BROADCAST,1)# 定义广播地址和端口broadcast_address='<broadcast>'port=12345# 发送消息message='Hello, world!'sock.sendto(message.encode(),(broadcast_...
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1) PORT = 6454 network ='127.0.0.1'# '<broadcast>' s.sendto('Client broadcast message!'.encode('utf-8'), (network, PORT)) def formatdata(dvcid,dat): sendBuf=[0x41, 0x72,...
通过设置 Socket 的选项,我们可以开启广播或组播功能。 # 设置 Socket 的属性udp_socket.setsockopt(socket.SOL_SOCKET,socket.SO_BROADCAST,1)udp_socket.setsockopt(socket.IPPROTO_IP,socket.IP_MULTICAST_TTL,2) 1. 2. 3. 上述代码中,我们使用setsockopt()方法来设置 Socket 的选项。socket.SOL_SOCKET表示当前 ...

INADDR_ANY和INADDR_BROADCAST是被保留的IP地址分别代表任意IP地址和广播地 址; INADDR_LOOPBACK 代表loopback设备,总是地址127.0.0.1。这些变量是32位字节数字形式的。 getfqdn([name])函数返回关于给定主机名的全域名(如果省略,则返回本机的全域名)。 server.py import socket ip_port=('127.0.0.1',5555) ...
