Question

我正在使用geventwebsockets但是甚至无法让示例应用运行起来。下面的代码给出了错误：

Traceback（最近一次调用最后一次）：文件＆＃34; /usr/local/lib/python2.7/dist-packages/gevent/pywsgi.py" ;,第884行，在handle_one_response中 self.run_application（）File＆＃34; /usr/local/lib/python2.7/dist-packages/geventwebsocket/handler.py"，第88行，在run_application中 return super（WebSocketHandler，self）.run_application（）File＆＃34; /usr/local/lib/python2.7/dist-packages/gevent/pywsgi.py" ;,第870行，在run_application中 self.result = self.application（self.environ，self.start_response）文件＆＃34; /usr/local/lib/python2.7/dist-packages/geventwebsocket/resource.py" ;, 第90行，在通话中引发异常（＆＃34;没有定义应用程序＆＃34;）例外：没有定义应用程序

from geventwebsocket import WebSocketServer, WebSocketApplication, Resource

class EchoApplication(WebSocketApplication):
    def on_open(self):
        print "Connection opened"

    def on_message(self, message):
        self.ws.send(message)

    def on_close(self, reason):
        print reason

WebSocketServer(
    ('', 8000),
    Resource({'/': EchoApplication})
).serve_forever()

我一直在圈子里跑来跑去。谁能帮我吗？非常感谢。

对你有用吗</ p>

如果添加echo_app

def echo_app(environ, start_response):
    websocket = environ.get("wsgi.websocket")

    if websocket is None:
        return http_handler(environ, start_response)
    try:
        while True:
            message = websocket.receive()
            websocket.send(message)
        websocket.close()
    except geventwebsocket.WebSocketError, ex:
        print "{0}: {1}".format(ex.__class__.__name__, ex)

和传递它

print "Running %s from %s" % (agent, path)
WebSocketServer(("", 8000), echo_app, debug=False).serve_forever()
