403 error occurred in win server2008+IIS7 installation django environment

due to the business need to assemble the django environment in the win server2008+IIS7 environment, the Python related libraries are installed normally and the, django runserver is running normally.
after installing wfastcgi, add the web.config, code to the root directory of the django project as follows:

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
        <system.webServer>
            <handlers>
                <add name="Python FastCGI" 
                     path="*" 
                     verb="*" 
                     modules="FastCgiModule" 
                     scriptProcessor="c:\python\python.exe|c:\python\lib\site-packages\wfastcgi.py" 
                     resourceType="Unspecified" 
                     requireAccess="Script"/>
            </handlers>
        </system.webServer>
        <appSettings>
            <add key="WSGI_HANDLER" value="django.core.wsgi.get_wsgi_application()" />
            <add key="PYTHONPATH" value="D:\wwwroot\yzf\MyDjango\MyDjango" />
            <add key="DJANGO_SETTINGS_MODULE" value="MyDjango.settings" />
        </appSettings>
    </configuration>
