At the early stage of. NET development, Microsoft provided a WEB development model called WebForm, which tried to eliminate the gap between Web and desktop and establish a consistent development experience. However, the ideal is very plump, and the reality is very skinny. The Web development method is completely different from the desktop software. Compared with WebForm, the later developed MVC obviously meets the needs of Web developers. The code quality is significantly improved, and the performance is also optimized a lot.

When I was working on the MVC project, I had some habits:

1. encapsulate the frequently used methods in Request and Response as extension methods, such as the method for obtaining logon UserId:

public static AuthMemberInfo GetMember(this HttpRequestBase request){    if (request.IsAuthenticated)    {        HttpCookie authCookie = request.Cookies[FormsAuthentication.FormsCookieName];        FormsAuthenticationTicket Ticket = FormsAuthentication.Decrypt(authCookie.Value);        return JsonConvert.DeserializeObject<AuthMemberInfo>(Ticket.UserData);    }    return null;}

2. Permission verification inherits the AuthorizeAttribute class and implements its own authentication logic:

public override void OnAuthorization(AuthorizationContext filterContext){    var user = filterContext.HttpContext.Request.GetMember();    if (user == null)    {        filterContext.Result = new RedirectResult(FormsAuthentication.LoginUrl            + "?returnUrl=" + filterContext.HttpContext.Server.UrlEncode            (filterContext.HttpContext.Request.RawUrl));        return;    }}

In this way, add this Attribute to any Controller or method that requires permission verification.

3. All controllers inherit the custom BaseController to perform unified behavior when necessary, such as logging in OnException.

4. MVC uses the JSON serializer of the framework to compare the disadvantages. In particular, date processing is not in the ISO format, which makes front-end JS troublesome. We can handle the Override Json method in BaseController:

protected override JsonResult Json(object data, string contentType,     Encoding contentEncoding, JsonRequestBehavior behavior){    return new JsonNetResult    {        Data = data,        ContentType = contentType,        ContentEncoding = contentEncoding,        JsonRequestBehavior = behavior    };}

JsonNetResult uses Json.net as the serializer, which is flexible:

public class JsonNetResult : JsonResult{    public override void ExecuteResult(ControllerContext context)    {        if (context == null)            throw new ArgumentNullException("context");        var response = context.HttpContext.Response;        response.ContentType = !String.IsNullOrEmpty(ContentType) ? ContentType : "application/json";        if (ContentEncoding != null)            response.ContentEncoding = ContentEncoding;        if (Data == null)            return;        var serializedObject = JsonConvert.SerializeObject(Data, Formatting.Indented,            new StringEnumConverter { CamelCaseText = false });        response.Write(serializedObject);    }}

5. After Global. asax detects a Global exception, it is handed over to ErrorController for processing:

Var routeData = new RouteData (); routeData. values. add ("controller", "Error"); routeData. values. add ("action", "ThrowError"); routeData. values. add ("message", "Sorry, an internal error occurred on the server. "); Server. clearError (); // output service exception information IController errorController = new ErrorController (); errorController. execute (new RequestContext (new HttpContextWrapper (this. context), routeData ));

How to Implement aspnet mvc?

The problem is widespread in space. It is recommended that you learn mvc first. If you learn about it, you can look at mvc-related projects or the source code of mvc. Good luck! Think more, practice diligently, do not simply look at and do not practice!

How to create the aspnet mvc Project

Install Visual Studio 2008 + SP1, install Microsoft's asp.net mvc Framework, and find the MVC project in the category of new Web applications.
