ASP.NET Core - 空结构

Question

博客控制器

我的 BlogController.Cs (ASP.NET Core 2.1) 中有以下代码：

namespace FiorelloTask.Areas.AdminF.Controllers
{
    [Area("AdminF")]
    public class BlogController : Controller
    {
        private AppDbContext _context;
        private IWebHostEnvironment _env;

        public BlogController(AppDbContext context, IWebHostEnvironment env)
        {
            _context = context;
            _env = env;
        }

        public IActionResult Index()
        {
            List<Blog> blogs = _context.Blogs.ToList();
            return View(blogs);
        }
                       
        public IActionResult Create()
        {
            return View();
        }

        [HttpPost]
        [ValidateAntiForgeryToken] 
        public async Task<IActionResult> Create(Blog blog)
        {
            //validationstate-requiredolanlar
            if (ModelState["Photo"].ValidationState == Microsoft.AspNetCore.Mvc.ModelBinding.ModelValidationState.Invalid)
            {
                return View();
            }
                
            if (!blog.Photo.IsImage())
            {
                ModelState.AddModelError("Photo", "Accept only image!");
                return View();
            }

            if (blog.Photo.ImageSize(10000))
            {
                ModelState.AddModelError("Photo", "1mq yuxari olabilmez!");
                return View();
            }
                
            if (!ModelState.IsValid)
            {
                return View();
            }

            bool isExistName = _context.Blogs.Any(c => c.Title.ToLower() == blog.Title.ToLower());

            if (isExistName)
            {
                ModelState.AddModelError("Name", "Eyni adlı kategoriya mövcuddur.");
                return View();
            }

            // string path = @"C:\Users\TOSHIBA\Desktop\FiorelloAdminF\FiorelloTask\wwwroot\img\";
                
            string fileName = await blog.Photo.SaveImage(_env, "img");

            Blog newBlog = new Blog();
            newBlog.Desc = blog.Desc;
            newBlog.Title = blog.Title;
            newBlog.Image = fileName;

            await _context.Blogs.AddAsync(newBlog);
            await _context.SaveChangesAsync();
                
            return RedirectToAction("Index");
        }

        public async Task<IActionResult> Delete(int? id)
        {
            if (id == null) 
                return NotFound();

            Blog dbBlog = await _context.Blogs.FindAsync(id);

            if (dbBlog == null) 
                return NotFound();

            _context.Blogs.Remove(dbBlog);
            await _context.SaveChangesAsync();

            return RedirectToAction(nameof(Index));
        }
    }
}
            

我在尝试在 ASP.NET Core Web 应用程序上为 OData 配置批处理时遇到了一些问题。 我到处搜索（几乎），找不到正确的答案。 我不确定当前仍处于测试阶段的 AspNetCore.Odata 版本 7.0.0 是否支持批处理。

仪表板

我的DashBoard.Cs上有以下代码：

        using Microsoft.AspNetCore.Authorization;
        using Microsoft.AspNetCore.Mvc;
        
        namespace FiorelloTask.Areas.AdminF.Controllers
        {
            public class DashboardController : Controller
            {
                [Area("AdminF")]
                [Authorize(Roles ="Admin")]  
                public IActionResult Index()
                {
                    return View();
                }
            }
        }
        

要在用户登录时创建令牌，我有 ProductController 服务：

        namespace FiorelloTask.Areas.AdminF.Controllers
        {
            [Area("AdminF")]
            
            public class ProductController : Controller
            {
            private AppDbContext _context;
                    public ProductController(AppDbContext context)
                    {
                        _context = context;
        
                    }
                    public IActionResult Index(int take=5,int pageSize=1)
                {
                    List<Product> products = _context.Products
                        .Include(p => p.Category)
                        .Skip((pageSize-1)*take)
                        .Take(take)
                        .ToList();
        
                    Pagination<ProductVM> pagination = new Pagination<ProductVM>
                    (
                           ReturnPageCount(take),
                            pageSize,
                        MapProductToProductVM(products)
                     
                        
                    );
                    return View(pagination);
                }
                private List<ProductVM> MapProductToProductVM(List<Product> products)
                {
                    //List<ProductVM> productVMs = new List<ProductVM>();
        
                    //foreach (var item in products)
                    //{
                    //    ProductVM product = new ProductVM
                    //    {   
                    //        Id=item.Id,
                    //        Name = item.Name,
                    //        ImageUrl=item.ImageUrl,
                    //        Count=item.Count,
                    //        Price=item.Price,
                    //        CategoryName=item.Category.Name
        
        
                    //    };
                    //    productVMs.Add(product);
                    //}return productVMs;
        
                    List<ProductVM> productVMs = products.Select(p => new ProductVM
                    {
                        Id=p.Id,
                        Name=p.Name,
                        ImageUrl=p.ImageUrl,
                        Count=p.Count,
                        Price=p.Price,
                        CategoryName=p.Category.Name
                    }).ToList();
                    return productVMs;
                }
        
                private int ReturnPageCount(int take)
                {
                 int productCount = _context.Products.Count();
        
                    return (int)Math.Ceiling(((decimal)productCount/take));
                }
            }
        }
    

我对此的第一个看法是，没有任何启动授权/身份验证方法检查令牌，或者至少除了 TokenValidationParameters 之外我没有提供它。

我假设它是因为 Token 组合而起作用的，并且服务会分解它以提取当前用户并将其插入 Identity。
