ZMQ_SUBSCRIBE属性将会在ZMQ_SUB类型的socekt上创建一个新的消息过滤标志。新建立的ZMQ_SUB类型socket会对进入socket的所有消息进行过滤,这样你就可以使用这个属性来建立最初的消息过滤项。 一个option_value的长度是0的过滤属性会订阅所有的广播消息。一个非空的option_value值会只订阅所有以option_value的值为前缀的...

socket.setsockopt(zmq.SUBSCRIBE,zip_filter) 第二个参数就是你期望的过滤条件,只有那些以这个过滤条件开头的消息才会被接收 最后是自问自答环节 问题1: 如果想创建多个socket怎么写? 答: 一个上下文可以创建任意多个socket,完全不受限制 问题2: 明明先启动了客户端,后启动的服务端,为啥有些消息却没有收到呢?
