zeromq 和 bind_to_random_port - 如何选择端口

Question

在python中，我使用以下内容:

    context = zmq.Context()
    socket = context.socket(zmq.PUSH)
    socket.bind_to_random_port('tcp://*', min_port=6001, max_port=6004, max_tries=100)
    port_selected = socket.???????

我怎么知道选择了哪个端口？我将在 redis 中有一个查找表供 worker 阅读。

我正在使用推拉模型。我需要让工作人员知道要连接到哪些端口。

我必须这样做，因为我在 uwsgi 中使用了 gevent 循环并指定了一个简单的盲区和错误，因为 fork 。如果使用 bind_to_random_port 然后选择一个端口，我只是不知道是哪个。

port_selected = socket.bind_to_random_port('tcp://*', min_port=6001, max_port=6004, max_tries=100)
