내 프로젝트에 게시물을 업로드하려고 할 때 405 오류가 발생합니다.

내 개발 블로그에 게시물을 업로드하는 데 문제가 있습니다. MVC 프레임 워크를 사용하여 게시물을 업로드하려고합니다. 블로그를 만드는 방법에 대한 다양한 가이드를 따르려고합니다.

다음은 Post 클래스입니다.

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Threading.Tasks;

namespace ProjectWebApp.Models
{
    public class Post
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int PostID { get; set; }
        [Required]
        public string Title { get; set; }
        [Required]
        public string Content { get; set; }
        public string Author { get; set; }
        public int Likes { get; set; }
        [Required]
        public DateTime DateCreated { get; set; }
        public DateTime? DateUpdated { get; set; }
        public ICollection<PostTag> PostTags { get; set; }
    }
}

다음은 BlogDBContext입니다.

using Project.Models;
using Microsoft.EntityFrameworkCore;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ProjectBlogWebApp.Data
{
    public class BlogDbContext : DbContext
    {
        public BlogDbContext(DbContextOptions<BlogDbContext> options) : base(options)
        {
            Database.EnsureDeleted();
            if (Database.EnsureCreated() == true)
            {
                Database.EnsureCreated();
            }
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<PostTag>().HasKey(p => new {p.PostID, p.TagID});
            modelBuilder.Entity<PostTag>().HasOne(pt => pt.Post).WithMany(p => p.PostTags)
                .HasForeignKey(pt => pt.PostID);
            modelBuilder.Entity<PostTag>().HasOne(pt => pt.Tag).WithMany(t => t.PostTags)
                .HasForeignKey(pt => pt.TagID);
        }



        public DbSet<Post> Posts { get; set; }

        public DbSet<Tag> Tags { get; set; }

        public DbSet<PostTag> PostTags { get; set; }
    }
}

다음은 PostController 클래스입니다.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using ProjectWebApp.Data;
using ProjectWebApp.Models;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.ModelBinding;
using Microsoft.EntityFrameworkCore;

namespace ProjectWebApp.Controllers
{
    public class PostController : Controller
    {
        private BlogDbContext _dbBlogContext;

        public PostController(BlogDbContext dbContext)
        {
            _dbBlogContext = dbContext;
        }

        public IActionResult Index()
        {
            var postList = _dbBlogContext.Posts.ToList();

            return View(postList);
        }
        [HttpGet, Route("Create")]
        public IActionResult Create()
        {
            return View(new Post());
        }

        [HttpGet, Route("Edit")]
        public IActionResult Edit()
        {
            
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> CreatePostAsync([Bind("Title", "Content")] Post post)
        {
            try 
            {
                post.Likes = 0;
                post.DateCreated = DateTime.Now;
                post.Author = "Leonard Morrison";
                _dbBlogContext.Add(post);
                await _dbBlogContext.SaveChangesAsync();

                
            }

            catch (DbUpdateException)
            {
                ModelState.TryAddModelError( "Error: Post was not added properly!", "Sorry, the Post was not added properly. Please let me know if this problem persists");
            }

            return View(post);
        }

        [HttpGet]
        public IActionResult Show(int ID)
        {
            var post = getPost(ID);
            return View(post);
        }

        [HttpGet]
        public IActionResult Edit(int ID)
        {
            var post = getPost(ID);
            return View(post);
        }
        [HttpPatch]
        public IActionResult Update(int id)
        {
            var post = _dbBlogContext.Posts.Find(id);
            _dbBlogContext.Posts.Update(post);
            return RedirectToAction("Index");
            
        }

        [HttpDelete]
        public IActionResult RemovePost(int id)
        {
            Post deletedPost = getPost(id);

            _dbBlogContext.Posts.Remove(deletedPost);

            _dbBlogContext.SaveChanges();

            return RedirectToAction("Index");
        }


        public Post getPost(int ID)
        {
            var post = _dbBlogContext.Posts.First(p => p.PostID == ID);

            return post;
        }

    }
}

마지막으로 시작 소스 코드는 다음과 같습니다.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using ProjectWebApp.Data;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.EntityFrameworkCore;
using Microsoft.AspNetCore.Http;


namespace ProjectBlogWebApp
{
    public class Startup
    {



        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();


            services.AddDbContext<BlogDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddScoped<BlogDbContext, BlogDbContext>();

        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();

            //The Main EndPoint Routes
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id}");
            });
            
            //The Post Endpoints Routes
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(name: "post",
                    pattern: "{controller=Post}/{action=Index}/{title?}");

            });
        }
    }
}

오류가 정확히 어디인지 모르기 때문입니다. 하지만이 405 오류가 발생하는 곳이 필요합니다.

감사.
