❔ ASP.NET to .net Core

Im trying to convert my asp.net project to .net core. I have a class thats using Httpcontext in some getter functions. I cant convert this class to .net core class. Can you help me ?
public static User CurrentUser { get { var ck = HttpContext.Request.Cookies[TOKEN_COOKIE_NAME]; Guid token; if (ck != null && Guid.TryParse(ck.Value, out token)) { var key = "BlueCMSUser" + token; if (HttpContext.Current.Cache[key] == null) { var user = User.GetByToken(token); if (user != null) { HttpContext.Current.Cache.Add(key, user, null, System.Web.Caching.Cache.NoAbsoluteExpiration, TimeSpan.FromMinutes(15), System.Web.Caching.CacheItemPriority.Default, null); } else { RemoveToken(); } } return HttpContext.Current.Cache[key] as User; } return null; } set { var ck = HttpContext.Current.Request.Cookies[TOKEN_COOKIE_NAME]; Guid token; if (ck != null && Guid.TryParse(ck.Value, out token)) { var key = "CMSUser" + token; HttpContext.Current.Cache[key] = value; } } } this is the code im trying to convert

is there anyway i can use HttpContext directly without using constructor like this ? private readonly HttpContext _httpContext; public User(IHttpContextAccessor httpContextAccessor, IMemoryCache memoryCache) { _httpContext = httpContextAccessor.HttpContext; _cache = memoryCache; }

HttpContext is now a property on your controllers. If you need it outside of your controller, you inject the accessor as above also, please use $code when showing blocks

Only in a controller. Not outside it.

Use the IHttpContextAccessor if you need access outside of a controller. Thats all I can say, as its the answer.

        static public List<User> GetList(int pageSize, int currentPage, out int totalCount)
        {
            using (EntityDBContext db = new EntityDBContext())
            {
                var data = (from o in db.Users orderby o.FirstName, o.LastName where o.IsDeleted == false select o);
                totalCount = data.Count();
                return data.Skip(pageSize * (currentPage - 1)).Take(pageSize).ToList();
            }
        }

        static public List<User> GetList(int pageSize, int currentPage, out int totalCount)
        {
            using (EntityDBContext db = new EntityDBContext())
            {
                var data = (from o in db.Users orderby o.FirstName, o.LastName where o.IsDeleted == false select o);
                totalCount = data.Count();
                return data.Skip(pageSize * (currentPage - 1)).Take(pageSize).ToList();
            }
        }

No suitable constructor was found for entity type 'User'. The following constructors had parameters that could not be bound to properties of the entity type: Cannot bind 'httpContextAccessor' in 'User(IHttpContextAccessor httpContextAccessor, IMemoryCache memoryCache)' Note that only mapped properties can be bound to constructor parameters. Navigations to related entities, including references to owned types, cannot be bound.' im getting this error

Pobiega•2y ago

This is some fairly cursed code my friend User appears to be an entity model, and should absolutely not have a static CurrentUser property

👻 Elektrikli Erol👻OP•2y ago

So my approach is wrong .. what is the best approach here ?

Pobiega•2y ago

I'd probably use something like...

👻 Elektrikli Erol👻OP•2y ago

yes you are right

Pobiega•2y ago

public class UserContext : IUserContext
...
ctor(IHttpContextAccessor)

public class UserContext : IUserContext
...
ctor(IHttpContextAccessor)

then you add a similar prop/method on this the idea is you dont want to mix your entity with your httpcontext logic

👻 Elektrikli Erol👻OP•2y ago

okay then i split my functions related to httpcontext to a different class

Pobiega•2y ago

yeah, exactly keep User as a domain entity

👻 Elektrikli Erol👻OP•2y ago

oh okay thanks for help

Pobiega•2y ago

give it a spin

👻 Elektrikli Erol👻OP•2y ago

okay let me try ^^
