psutil
是一个 Python 库,用于获取系统使用情况,如 CPU、内存、磁盘和网络接口等
- 获取网络接口信息:
import psutil net_interfaces = psutil.net_if_addrs() for interface, addrs in net_interfaces.items(): print(f"Interface: {interface}") for addr in addrs: print(f" Address: {addr.address}, Mask: {addr.netmask}, Broadcast: {addr.broadcast}")
- 获取网络连接状态:
import psutil
connections = psutil.net_connections()
for conn in connections:
print(f"Protocol: {conn.info['type']}, Local Address: {conn.laddr}, Remote Address: {conn.raddr}")
- 获取网络流量统计信息:
import psutil net_io_counters = psutil.net_io_counters() print(f"Bytes Sent: {net_io_counters.bytes_sent}") print(f"Bytes Received: {net_io_counters.bytes_recv}")
- 获取 TCP 和 UDP 连接的详细信息:
import psutil tcp_connections = psutil.net_tcp_stats() udp_connections = psutil.net_udp_stats() print("TCP Connections:") for conn, stats in tcp_connections.items(): print(f" State: {stats.status}, Recv Queue: {stats.recv_queue}, Send Queue: {stats.send_queue}") print("\nUDP Connections:") for conn, stats in udp_connections.items(): print(f" Recv Queue: {stats.recv_queue}, Send Queue: {stats.send_queue}")
这些示例展示了如何使用 psutil
库来获取网络编程相关的信息。你可以根据自己的需求对这些示例进行修改和扩展。
