Autobahn Application Runner 不是 运行 Apps

Autobahn Application Runner is not running Apps

我对 Autobahn 和 WAMP(Web 应用消息传递协议)还很陌生。

我只是基于 http://autobahn.ws/python/wamp/programming.html and https://github.com/crossbario/crossbarexamples/blob/master/votes/python/votes.py

创建一个简单的应用程序组件

下面是我的服务器端Python

from autobahn.asyncio.wamp import (
    ApplicationSession,
    ApplicationRunner
)
from autobahn import wamp

from asyncio import coroutine


class MyComponent(ApplicationSession):
    @wamp.register("com.myapp.add2")
    def add2(self, x, y):
        print("added 2")
        return x + y

    @wamp.register("com.myapp.add3")
    def add3(self, x, y, z):
        print("added 3")
        return x + y + z

    @coroutine
    def onJoin(self, details):
        res = yield from self.register(self)
        print("{} procedures registered.".format(len(res)))

if __name__ == '__main__':
    runner = ApplicationRunner(url="ws://localhost:8080/ws", realm="realm1")
    runner.run(MyComponent)

和客户端

<script src="http://autobahn.s3.amazonaws.com/autobahnjs/latest/autobahn.min.jgz"></script>

<script>
    var connection = new autobahn.Connection({
        url: "ws://localhost:8080/ws",
        realm: "realm1"
    });

    connection.onopen = function (session, details) {
        session.call("com.myapp.add2", [2,3]).then(session.log);
        session.call("com.myapp.add3", [2,3,4]).then(session.log);
    };

    connection.onclose = function (reason, details) {
        console.log("Connection lost: " + reason);
    };

    connection.open();
</script>
</body>
</html>

错误

看起来这与https://github.com/hwmrocker/hextest/issues/2 but I can't get my head around. I can't even find a sample that works. This one (https://github.com/tavendo/AutobahnPython/tree/master/examples/asyncio/wamp/wamplet/wamplet1) 相似,但它也有同样的问题。

令人惊讶的是,当我 运行 在同一端口上的外部 Crossbar 示例和 运行 上面的示例时,它就像魔术一样工作,我可以在控制台上看到结果。

我找到了这个 (https://github.com/tavendo/AutobahnPython/blob/master/examples/asyncio/wamp/basic/server.py),但它看起来很复杂。

请帮帮我。

谢谢你的进阶。

您的代码无需修改即可为我工作:

您的应用包含 2 个 WAMP 应用程序组件:浏览器端(使用 AutobahnJS)和服务器端(使用 AutobahnPython/Python3/asyncio)。

要让这两个组件相互通信,两个组件都需要连接到 WAMP 路由器。我用了 Crossbar.io.

请注意,您的 Python 组件在逻辑上 是一个 server-side 组件,但在技术上不是 服务器:它不打开侦听端口或什么,但它连接到WAMP路由器。
