It's important to know the function of characteristics like HttpPostAttribute. Identical characteristics are defined for other HTTP verbs.
Using web page like a route parameter with attribute routing is a typical error. Undertaking that results in inconsistent and puzzling habits with URL technology.
Relaxation APIs need to use attribute routing to design the application's features being a set of assets the place operations are represented by HTTP verbs.
Attribute routes help the same inline syntax as traditional routes to specify optional parameters, default values, and constraints.
Route constraints are Utilized in both equally attribute-centered and traditional-primarily based routing in order that the values presented within the URL match the expected info varieties or formats. Enable’s say we want to make a route matching the next URLs.
As you are able to see in the above figure, the route is configured using the MapRoute() extension way of RouteCollection, where by name is "Default", url pattern is " controller / motion / id " and defaults parameter for controller, action strategy and id parameter.
HomeController matches a set of URLs comparable to exactly what the default traditional route controller=Home / action=Index / id? matches.
Employing places lets an app to obtain a number of controllers with the very same name, assuming that they may have diverse locations. Employing spots produces a hierarchy for the objective of routing by incorporating A further route parameter, region to controller and action.
In addition to earlier mentioned constraint, we might also outline custom made constraint to match our certain want. Take into consideration a situation, exactly where a particular feature or style of your application will not operate in Google chrome but operates in all other browser like Web Explorer and FireFox. In this case we could use custom made constraint routing.
Now run the application and navigate to the following URLs, and you'll begin to see the output as predicted. You need to change the port range.
To create attribute routing less repetitive, route characteristics to the controller are combined with route characteristics on the person actions.
Attribute routing supports defining a number of routes that get to the identical motion. The most routing in asp.net mvc common utilization of the is to imitate the conduct with the default standard route as demonstrated in the subsequent instance:
Simplicity: It reduces the necessity to define routes explicitly For each motion strategy or controller; rather, it takes advantage of default conventions.
Utilizing standard routing With all the default route permits producing the app without having to think of a completely new URL sample for each action. For an application with CRUD model actions, possessing consistency with the URLs throughout controllers:
