My routes are as follows:
app.add_route('/v1/my_route', MyResource())
app.add_route('/v1/my_route/{app_id}', MyResource())
app.add_route('/v1/my_route2/any_route', AnyRouteResource())
app.add_route('/v1/my_route2/any_route/{app_id}', AnyRouteResource())
and Middleware is something similar to
class MyMiddleware(object):
def process_request(self, req, resp):
/** Here i want to get <app_id> value if it is passed **/

The other way to access the Route parameters in the middlware involves gettting all the parameters. Imagine you had a route like this /params/ {id}/ {category}/ {name}. All the route params are usually saved in an array, which in a middleware is accessible through $request->route ()->parameters ().
In this case, the name of the parameter is file_path, and the last part, :path, tells it that the parameter should match any path. So, you can use it with:
In this article, we’ll look at how to get path params in React Router. To get path params in React Router, we can use the useParams hook. We create the Child component that calls the useParams hook to return an object with the route params in the URL. And we render the value of the id param on the page.
Getting the URL params. To get the url parameter from a current route, we can use the useParams () hook in react router v5. Consider, we have a route like this in our react app. Now, we can access the :id param value from a Users component using the useParams () hook. In React router v4, you can access it using the props.match.params.id.
You can get every attribute of the request object from req. For example, to get the path of your resource:
class MyMiddleware(object):
def process_request(self, req, resp):
path = req.path
# process your path here
Check the docummentation for more info about requests.
If you want to get the app_id directly, just extend the method with params, falcon will do the job.
class MyMiddleware(object):
def process_request(self, req, resp, params):
app_id = params["app_id"]
There is process_resource(self, req, resp, resource, params) method in the base middleware. You can override it. There params is a dict like object with params extracted from the uri template fields.
