Flask-SocketIO在Azure上不起作用

Question

I have a website that works perfectly when I host it locally, but on Azure the socketio requests result in an http 400 error. It is a Python flask app that uses flask-socketio. The socket I connect to locally is ' http://127.0.0.1:5000 ,' but on Azure I connect to http://myurl.azurewebsites.net:80 because the Azure documentation says it listens on ports 80 and 443. I'm using javascript with jquery and this is how I create the socket:

var socket = io.connect('http://myurl.azurewebsites.net:80');

I've found many questions from people who had this issue, but they all seem to be using node.js, and the solution involves the node.js require() method. I can't find a solution using just javascript or jquery. Is this even possible? Thanks.

I tried to reproduce your issue but failed. I followed the sample here . After deploying to Azure, installing the requirements and enabling Web Sockets in Azure portal > App > Application Settings , it works all fine.Please refer to my components.

Output :

My web.config :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
    <webSocket enabled="true" />
  <handlers>
   <add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" />
  </handlers>

  <httpPlatform processPath="D:\home\Python27\python.exe" arguments="run_waitress_server.py" requestTimeout="00:04:00" startupTimeLimit="120" startupRetryCount="3" stdoutLogEnabled="true">
   <environmentVariables>
    <environmentVariable name="PYTHONPATH" value="D:\home\site\wwwroot" />
    <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
   </environmentVariables>
  </httpPlatform>

</system.webServer>
</configuration>

Hope it helps you.
