Now, many of us may be considering whether it would be possible to just declare GET and POST methods inside a View class and let Flask handle the rest of the stuff. The answer to this question is MethodView. Let's write our previous snippet using MethodView:

from flask.views import MethodView class GetPostRequest(MethodView): 
 
    def get(self): 
        bar = request.args.get('foo', 'bar') 
        return 'A simple Flask request where foo is %s' % bar 
 
    def post(self): 
        bar = request.form.get('foo', 'bar') 
        return 'A simple Flask request where foo is %s' % bar 
 
app.add_url_rule( 
    '/a-request', 
    view_func=GetPostRequest.as_view('a_request') 
)
