Websockets 问题 - 灵活的应用程序引擎

Question

过去几天，当我尝试运行示例 python websocketFlexible-app-engine 应用程序时，出现以下错误（https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/appengine /灵活/websockets）。它以前可以工作，但现在当我运行时，我看到以下错误。

当我使用“gunicorn -b 127.0.0.1:8080 -kflask_sockets.worker main:app”在本地运行时，我没有看到这个问题。

我仅在部署在谷歌云中时才看到此问题。

  File "/env/lib/python3.6/site-packages/gevent/pywsgi.py", line 999, in handle_one_response
    self.run_application()
  File "/env/lib/python3.6/site-packages/geventwebsocket/handler.py", line 75, in run_application
    self.run_websocket()
  File "/env/lib/python3.6/site-packages/geventwebsocket/handler.py", line 52, in run_websocket
    list(self.application(self.environ, lambda s, h, e=None: []))

    return self.wsgi_app(environ, start_response)

    handler, values = adapter.match()
  File "/env/lib/python3.6/site-packages/werkzeug/routing.py", line 2026, in match
    raise WebsocketMismatch()

请帮忙

Werkzeug 发布了 2.0.0 版本，这也给我带来了麻烦。

https://github.com/pallets/werkzeug/releases/tag/2.0.0

在需求文件顶部添加

Werkzeug==1.0.1

解决了我的问题。
