SUB端口可以连接多个PUB端口

context = zmq.Context()socket = context.socket(zmq.SUB)print("Collecting updates from weather server...")socket.connect("tcp://localhost:5666")socket.connect("tcp://localhost:5667")#socket.close() # 可以根据需要关闭连接

 context is the container for all sockets in a single process, and acts as the transport for inproc sockets, which are the fastest way to connect threads in one process.

Call  once at the start of a process, and  once at the end.

问题：

  如果写错了对端地址，根本不知道。
