Windows Server VM上的Django Hello World Web应用

Question

Good Evening, I am trying to setup hello world app on azure cloud. I am following the tutorial Django hello world web app on windows server vm

After doing all the set up when I navigate to the http://localhost/

I get following error

I saw in some post, people suggested to add django.setup() like for standalone apps, that did not work or I put that in wrong spot. I tried to run python manage.py runserver and it ran without error.

Following is my web.config file

<configuration>
<appSettings>
    <add key="WSGI_HANDLER" value="django.core.handlers.wsgi.WSGIHandler()" />
    <add key="PYTHONPATH" value="C:\inetpub\wwwroot\resumeApp" />
    <add key="DJANGO_SETTINGS_MODULE" value="resumeApp.settings" />

    <!-- optional settings -->
    <add key="WSGI_LOG" value="C:\inetpub\wwwroot\resumeApp\Logs\resumeApp.log" />
</appSettings>
<system.webServer>
    <handlers>
        <add name="Python FastCGI" 
            path="*" 
            verb="*" 
            modules="FastCgiModule" 
            scriptProcessor="c:\users\compUser\appdata\local\programs\python\python36\python.exe|c:\users\compUser\appdata\local\programs\python\python36\lib\site-packages\wfastcgi.py" 
            resourceType="Unspecified" />
    </handlers>
</system.webServer>

This is my settings.py

In web.config , replace:

<add key="WSGI_HANDLER" value="django.core.handlers.wsgi.WSGIHandler()" />

with:

<add key="WSGI_HANDLER" value="django.core.wsgi.get_wsgi_application()" />

refer to django source code .
