带有 .NET 路由器的高速公路组件 (WampSharp)

Question

目前我正在使用 WAMP 原型，我很好奇这样的事情是否可行，因为我无法让它工作：

1.拥有用 c# (WampSharp) 编写的 WAMP 路由器：

const string location = "ws://127.0.0.1:9999/wsdemo";

try
{
    using (IWampHost host = new DefaultWampHost(location))
    {
        IWampHostedRealm realm = host.RealmContainer.GetRealmByName("realm1");
        host.Open();
        Console.WriteLine("Host is running on : " + location);
    }
}
catch(Exception exc)
{
    Console.WriteLine("Error : " + exc.ToString());
}

2.用python编写组件：

import random
from twisted.internet.defer import inlineCallbacks
from autobahn.twisted.util import sleep
from autobahn.twisted.wamp import ApplicationSession, ApplicationRunner

class Component(ApplicationSession):
    """
    An application component that publishes events with no payload
    and with complex payload every second.
    """

    @inlineCallbacks
    def onJoin(self, details):
        print("session attached")

        counter = 0
        while True:
            num = random.randint(0, 100)
            print("publishing : com.myapp.topic1", num)
            self.publish(u'com.myapp.topic1', num)
            counter += 1
            yield sleep(1)


if __name__ == '__main__':
    runner = ApplicationRunner(url=u"ws://127.0.0.1:9999/wsdemo", realm=u"realm1")
    runner.run(Component)

当我运行 python 脚本时，我得到了错误：

2017-02-20T19:49:46+0100 Main loop terminated.

根据http://autobahn.ws/python/wamp/programming.html#running-a-wamp-router

我们创建的组件尝试连接到 WAMP 路由器 在本地运行，它接受端口 8080 上的连接，并且对于 领域领域1。

我们建议的方法是使用 Crossbar.io 作为您的 WAMP 路由器。有 除了 Crossbar.io 之外的其他 WAMP 路由器。

这样的事情能实现吗？

您的 using 语句在程序结束之前处理路由器。

只需添加一个 Console.ReadLine();在 Console.WriteLine() 语句之后的 using 范围内的语句。应该可以的。
