Well done! Instead of ugly URLs like:
localhost:8000/Movies/Horror/Create?title=Spooky+Ghosts&length=120
You can now re-define them like:
localhost:8000/AddScaries/Spooky+Ghosts/120
In this lesson you learned:
- Typing a string after the
@page
directive will edit the page’s default route. - Typing parameters within curly braces after the
@page
directive will define a route template. - Route values can be made optional with a question mark
?
. - Route values can be constrained using the colon syntax and keyword constraints.
- The
asp-route-{value}
attribute can add additional information to an<a>
element’shref
attribute, either in the form of an additional route segment or query string, depending on how the route template is defined.
<!-- No URL segments --> @page <!-- Edit the default route --> @page "/Days" <!-- Add a route template --> @page "/Days/{day}" <!-- Constrain route value --> @page "/Days/{day:int}" <!-- Make route value optional --> @page "/Days/{day:int?}"
Instructions
Experiment with the links at localhost:8000/Days/
. Check that the URLs match your expectations and the code in Activity.cshtml.
