ZeroMQ的笔迹

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 zmq_ctx_new() once at the start of a process, and zmq_ctx_destroy() once at the end.

问题：

  如果写错了对端地址，根本不知道。
