无法在启动类中注入 IAntiforgery

Question

需要使用 IAntiforgery 进行 csrf 保护。只是试图注入服务。这样做时，我收到“尝试激活 'APi.Startup' 时无法解析类型 'Microsoft.AspNetCore.Antiforgery.IAntiforgery' 的服务”。错误。我在这里发布代码。希望社区能够在这里为我提供帮助。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using APi.Models;
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.Antiforgery;
using Microsoft.AspNetCore.Razor.TagHelpers;

 

namespace APi
{
    public class Startup
    {
        IAntiforgery _antiforgery;
        public Startup(IConfiguration configuration,IAntiforgery antiforgery)
        {
            Configuration = configuration;
            _antiforgery = antiforgery;
        }

 

        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.AddTransient<IAntiforgery>();
            services.AddDbContext<EmployeeContext>(options => 
            options.UseSqlServer(Configuration.GetConnectionString("SQLServerConnection")));
        }

 

        // 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();

 

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

你不能在启动构造函数中注入IAntiforgery。使用Generic Host（IHostBuilder）时，只能将以下服务类型注入Startup构造函数：

• IWebHostEnvironment
• IHostEnvironment
• IConfiguration
