MVC5 Learning Note Controller

Main reference book "ASP. MVC5 Advanced Programming (5th Edition)" Jon Galloway, etc.

1. MVC represents the model-view-controller. MVC is a pattern for developing applications that is well architected, testable, and easy to maintain. The MVC-based application contains:

Models: A class that represents the data for an application and enforces the data for the business rule using validation logic.

Views: template files that your application uses to dynamically generate HTML responses.

Controllers: The browser that processes the incoming request, the class retrieves the model's data, and then specifies the view template that returns the response to the browser.

2. The controller in the MVC pattern is primarily responsible for responding to user input and modifying the model when responding. The controller in the MVC pattern focuses on application flow, the processing of input data, and the provision of related view output data.

3. The adoption of the MVC pattern in web development requires that every user input in a Web application only takes the form of a request. For example, in ASP. NET MVC, each request is routed to a controller's method, and the controller is solely responsible for interpreting the requests, manipulating the model if necessary, and then selecting a view feedback to the user.

4. The only way to determine whether a class is a Controller class is to see if the class inherits from System.Web.Mvc.Controller.

5. The controller is the real core, each request must be handled by the controller, however some of these requests do not need model and view.
