socket链接服务器被拒

u99304454

>>> s_client.connect((host, port))

Traceback (most recent call last):

  File "<pyshell#7>", line 1, in <module>

    s_client.connect((host, port))

ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

老师，为啥会报这种错误呢？我查了下对应得端口没有被占用
