【问题描述】：

所以我在 .NET 5.0 上构建了一个 asp.net core web api 应用程序，它在我的机器上运行良好。今天我使用 aws 工具将它部署在弹性 beantalk AWS 上。 它在部署和填充时不会显示任何错误。它只是返回我找不到代码 404。 这是我的代码。

using Startup.cs
using System.Text;
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.IdentityModel.Tokens;
using Microsoft.OpenApi.Models;
using ShopApiNet5.Authentication;
using ShopApiNet5.Models;


namespace ShopApiNet5

    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.AddControllers();

            services.AddDbContext<ModelContext>(opt => opt.UseInMemoryDatabase("ModelDB"));

            services.AddIdentity<ApplicationUser, IdentityRole>(options => options.SignIn.RequireConfirmedAccount = true)
                .AddEntityFrameworkStores<ModelContext>()
                .AddDefaultTokenProviders();

            services.AddAuthentication(options =>
            
                options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
                options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;
            )

            .AddJwtBearer(options =>
            
                options.SaveToken = true;
                options.RequireHttpsMetadata = false;
                options.TokenValidationParameters = new TokenValidationParameters()
                
                    ValidateIssuer = true,
                    ValidateAudience = true,
                    ValidAudience = Configuration["JWT:ValidAudience"],
                    ValidIssuer = Configuration["JWT:ValidIssuer"],
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["JWT:Secret"]))
                ;
            );

            services.AddSwaggerGen(c =>
            
                c.SwaggerDoc("v1", new Microsoft.OpenApi.Models.OpenApiInfo  Title = "ShopApi", Version = "V1" );

                c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme()
                
                    Name = "Authorization",
                    Type = SecuritySchemeType.ApiKey,
                    Scheme = "Bearer",
                    BearerFormat = "JWT",
                    In = ParameterLocation.Header,
                    Description = "JWT Authorization header using the Bearer scheme. \r\n\r\n Enter 'Bearer' [space] and then your token in the text input below.\r\n\r\nExample: \"Bearer 12345abcdef\"",
                );
                c.AddSecurityRequirement(new OpenApiSecurityRequirement
                
                    
                          new OpenApiSecurityScheme
                            
                                Reference = new OpenApiReference
                                
                                    Type = ReferenceType.SecurityScheme,
                                    Id = "Bearer"
                                
                            ,
                            new string[] 

                    
                );
            );
        

        // 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();

                app.UseSwagger();
                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "TodoApi v1"));
            

            //app.UseHttpsRedirection();

            app.UseRouting();

app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            
                endpoints.MapControllers();
            );
        
    

这是我的 launchsettings.json

请帮帮我？？？？

【问题讨论】：

我现在正在尝试使用标准的 asp.net 核心 web 应用程序模板来重新制作这个项目，而不是 web api。希望这对我有帮助

没有帮助，遇到同样的问题...shopapismnet5webapp-dev.us-east-1.elasticbeanstalk.com 链接到我重新制作的应用程序，在一个简单的网络应用程序模板上

我尝试部署默认模板 web api 应用程序，但未启用 https。它已部署但环境没有响应，我很伤心

我点击了你的日志，出现了Request has expired的错误信息。我查了资料。为了解决这个问题，对象的所有者必须生成一个新的具有新到期日期的预签名 URL。如果您是对象的所有者，请参阅预签名或与他人共享对象的说明。

谢谢@Chaodeng，其实我。解决了这个问题:)

【参考方案1】：

所以我刚刚做了一个没有启用 https 的新应用程序，它就像我记得的那样工作。
