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.???????

我如何知道选择了哪个端口？我将用redis查找表格供工人阅读。

我正在使用推拉式模型。我需要让工人知道要连接的端口。

我必须这样做，因为我在uwsgi中使用gevent循环并指定一个简单的盲目索引和错误，因为fork。如果使用bind_to_random_port然后选择一个端口，我只是不知道哪个。

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

zeromq和bind_to_random_port - 如何选择端口
