HonoBearer Auth Middleware
The Bearer Auth Middleware provides authentication by verifying an API token in the Request header. The HTTP clients accessing the endpoint will add the Authorization header with Bearer {token} as the header value.
Using curl from the terminal, it would look like this:
curl -H 'Authorization: Bearer honoiscool' http://localhost:8787/auth/pagecurl -H 'Authorization: Bearer honoiscool' http://localhost:8787/auth/pageImport
