async_flask's Issues

Python 3.5 version

Is there any chance you could release a python 3.5 version of this? gevent-websocket now supports 3.5...

this code is not working

Hi,
I downloaded this code, but when run it I got this 👍

(colenv) C:\Users\alotfi\PycharmProjects\async_flask-master
λ python application.py

Thanks, your help is appreciated.

Would you mind adding a license to this repo?

Hi, I'd love to use and adapt some of your code for a personal project.
In the post on your website, you say

You can find all of the source code on GitHub, with instructions on how to install the necessary libraries etc. Feel free to adapt to your own needs, and leave any comments if you come up with something neat or have any problems.

However, I'd feel much more comfortable using and adapting if there was an actual license file in the repo (e.g. BSD-3-Clause but ultimately, it's your choice :)).

thread.isAlive() is deprecated

Thread.isAlive() is deprecated and hence needs to changed with thread.is_alive() for the project to work.

unsupported version of the Socket.IO

Installed package with the following command: pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org Flask-SocketIO==3.1.2

Error when launching the website shows the below information:

Only the first random generated number is shown, very slow to show new numbers

After a start, the first random generated number is shown instantly. However, subsequent numbers take ages to be displayed on the page. Any ideas?

gevent version

On some OSes (for example Ubuntu 1604 kernel 4.4.0-62) is needed to upgrade gevent to version 1.0.2. With version 1.0.1 "NameError: name 'PROTOCOL_SSLv3' is not defined" is raised

Of course it is enough to modify requirements.txt accordingly.

application.js file gets a net::ERR_ABORTED 404 (Not Found)

Hello everyone, I'm struggling with this for the past two days :'''(, and I have used it before and it was working.

So, I have just created a WS instance with Ubuntu 18.
I clone the repo in my /var/www/html/ and run the python application
The server seems to be running

`Server initialized for eventlet.

• Restarting with stat
  Server initialized for eventlet.
• Debugger is active!
• Debugger PIN: XXX-XXX-XXX
  (7604) wsgi starting up on http:// 127.0.0.1:5000`

When I load the page in my browser (tested with Chrome and Firefox, same result), I see the following error in the console:

GET http://ec2-XX-XX-XXX-XXX.eu-north-1.compute.amazonaws.com/async_flask/templates/static/js/application.js net::ERR_ABORTED 404 (Not Found)

... complaining about line 6 in the index.html file...

<script src="static/js/application.js"></script>

... so I change this to ...

<script src="../static/js/application.js"></script>

... and now I get this error in the browser console on each polling ...

GET http://ec2-XX-XX-XXX-XXX.eu-north-1.compute.amazonaws.com/socket.io/?EIO=3&transport=polling&t=1586010311097-0 404 (Not Found)

I have setup my Security Group in the AWS Dashboard. So there are Inbound rules for HTTP and SSH - 80 and 22 respectively.
