Features and technologies big collection Architecture Clean Architecture

 

 

1. Areas

Key code:

            app.UseMvc(routes =>            {                routes.MapRoute(                    name: "areaRoute",                    template: "{area:exists}/{controller}/{action}",                    defaults: new { action = "Index" });                routes.MapRoute(                    name: "default",                    template: "{controller=Home}/{action=Index}/{id?}");            });

Add an areaRoute, add the corresponding Areas folder, and add [Area ("Admin")] to the Controller in Areas.

2. ViewComponents

In the ViewComponents folder of the project, note that the corresponding view is in the Views \ Shared \ Components folder.

3. Middleware

Middleware for RequestIPMiddleware that records ip addresses and related information

Public class RequestIPMiddleware {private readonly RequestDelegate _ next; private readonly ILogger _ logger; public RequestIPMiddleware (RequestDelegate next) {_ next = next; _ logger = LogManager. getCurrentClassLogger ();} public async Task Invoke (HttpContext httpContext) {var url = httpContext. request. path. toString (); if (! (Url. contains ("/css") | url. contains ("/js") | url. contains ("/images") | url. contains ("/lib") {_ logger. info ($ "Url: {url} IP: {httpContext. connection. remoteIpAddress. toString ()} Time: {DateTime. now} ") ;}await _ next (httpContext) ;}} public static class RequestIPMiddlewareExtensions {public static IApplicationBuilder UseRequestIPMiddleware (this IApplicationBuilder builder) {return builder. useMiddleware <RequestIPMiddleware> ();}}

View Code4. Identity

Integrates Identity, extends User tables, and customizes User tables.

Permission Policy

            services.AddAuthorization(options =>            {                options.AddPolicy(                    "Admin",                    authBuilder =>                    {                        authBuilder.RequireClaim("Admin", "Allowed");                    });            });

Complexity of Logon password Registration

            services.AddIdentity<User, IdentityRole>(options =>            {                options.Password = new PasswordOptions() {                    RequireNonAlphanumeric = false,                    RequireUppercase=false                };            }).AddEntityFrameworkStores<DataContext>().AddDefaultTokenProviders();

 

5. EF Core

EF Core uses the Sqlite database.

Read configuration files

services.AddDbContext<DataContext>(options => options.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));

Use code to initialize a database

        private void InitializeNetCoreBBSDatabase(IServiceProvider serviceProvider)        {            using (var serviceScope = serviceProvider.GetRequiredService<IServiceScopeFactory>().CreateScope())            {                var db = serviceScope.ServiceProvider.GetService<DataContext>();                db.Database.Migrate();                if (db.TopicNodes.Count() == 0)                {                    db.TopicNodes.AddRange(GetTopicNodes());                    db.SaveChanges();                }            }        }

Project Tiering DataContext in Infrastructure, precautions for using the dotnet ef command

dotnet ef migrations add InitMigration --startup-project ../NetCoreBBS/NetCoreBBS.csproj

Update a specified field. You do not need to query the object first.

        public IActionResult EditSave(Topic topic)        {            _context.Attach(topic);            _context.Entry(topic).Property(r => r.Title).IsModified = true;            _context.Entry(topic).Property(r => r.Content).IsModified = true;            _context.SaveChanges();            return RedirectToAction("Index");        }

 

6. Configuration

Read the link string Configuration. GetConnectionString ("DefaultConnection ")

7. Partial Views

_ LoginPartial. cshtml head logon distribution View

_ PagerPartial. cshtml page distribution View

@ {Var pageindex = Convert. ToInt32 (ViewBag. PageIndex); var pagecount = Convert. ToInt32 (ViewBag. PageCount); pagecount = 0? 1: pagecount; pageindex = pageindex> pagecount? Pagecount: pageindex; var path = Context. request. path. value; var query = string. empty; var querys = Context. request. query; foreach (var item in querys) {if (! Item. key. equals ("page") {query + = $ "{item. key} = {item. value} & ";}} query = string. empty? "? ":"? "+ Query; path + = query; var pagestart = pageindex-2> 0? Pageindex-2: 1; var pageend = pagestart + 5> = pagecount? Pagecount: pagestart + 5;} <ul class = "pagination"> <li class = "prev previus_page @ (pageindex = 1? "Disabled": "") "> <a href =" @ (pageindex = 1? "#": $ "{Path} page = {pageindex-1}") ">&# 8592; previous Page </a> </li> <li @ (pageindex = 1? "Class = active": "")> <a rel = "start" href = "@ (path) page = 1 "> 1 </a> </li> @ if (pagestart> 2) {<li class = "disabled"> <a href = "#"> & hellip; </a> </li >}@ for (int I = pagestart; I <pageend; I ++) {if (I> 1) {<li @ (pageindex = I? "Class = active": "")> <a rel = "next" href = "@ (path) page = @ I "> @ I </a> </li >}}@ if (pageend <pagecount) {<li class = "disabled"> <a href = "#"> & hellip; </a> </li >}@ if (pagecount> 1) {<li @ (pageindex = pagecount? "Class = active": "")> <a rel = "end" href = "@ (path) page = @ pagecount "> @ pagecount </a> </li >}< li class =" next next_page @ (pageindex = pagecount? "Disabled": "") "> <a rel =" next "href =" @ (pageindex = pagecount? "#": $ "{Path} page = {pageindex + 1}") "> next page & #8594; </a> </li> </ul>

It is not well written and can be optimized to TagHelper.

8. Injecting Services Into Views

@inject SignInManager<User> SignInManager

@ Inject keyword

9. Dependency Injection and Controllers

public IActionResult Index([FromServices]IUserServices user)

FromServices can be injected in a specified Action or using constructor.

        private ITopicRepository _topic;        private IRepository<TopicNode> _node;        public UserManager<User> UserManager { get; }        public HomeController(ITopicRepository topic, IRepository<TopicNode> node, UserManager<User> userManager)        {            _topic = topic;            _node = node;            UserManager = userManager;        }

 

10. Release

I have previously written the corresponding Publishing Article ASP. NET Core and published it to the Ubuntu System in the Linux production environment.

Since project. json is changed to csproj, the release changes.

By default, the release is still the same as the dotnet publish, and csproj is changed during the release.

Edit NetCoreBBS. csproj

<RuntimeIdentifiers>ubuntu.14.04-x64</RuntimeIdentifiers>

The following is also the dotnet publish-r ubuntu.14.04-x64

Note that this node is released by default, and the server must also install the same version of runtime.

<RuntimeFrameworkVersion>1.0.0</RuntimeFrameworkVersion>

 

Some of the code can be mined by yourself.

NETCoreBBS started at RC2, and many people should have read this project. This article gives you a better understanding of this project.
