在 Azure 的 ASP.NET Core 3.1 应用程序中获取 swagger-ui 返回 404

Question

在加载/swagger/index.html页面时，浏览器找不到部署到Azure中的App Servicce所需的swagger-ui资源，返回404。在本地运行时有效。我的设置是：

  services.AddSwaggerGen(options =>
  {
      options.SwaggerDoc("v1", new OpenApiInfo
      {
          Title = "Nexus WebApp",
          Version = "v1"
      });
      options.CustomSchemaIds(type => type.ToString());
               
  });

 var builder = endpoints.CreateApplicationBuilder();

 builder.UseSwagger();

 builder.UseSwaggerUI(options =>
 {
     options.SwaggerEndpoint("/swagger/v1/swagger.json", "Nexus WebApp");
 });

 var pipeline = builder.Build();

 endpoints.Map("/swagger", pipeline)
     .RequireAuthorization(new AuthorizeAttribute());
 endpoints.Map("/swagger/index.html", pipeline)
     .RequireAuthorization(new AuthorizeAttribute());
 endpoints.Map("/swagger/{documentName}/swagger.json", pipeline)
     .RequireAuthorization(new AuthorizeAttribute());

我已经尝试过使用像 ..\swagger\v1/swagger.json 这样的 swagger 端点的相对路径，不幸的是，我尝试指定一个 RoutePrefix 都无济于事。我知道有人问过类似的问题，但不幸的是，似乎没有任何帮助。

有人有线索吗？

更新

这些是它返回 404 的资源：

• https://{domain}/swagger/swagger-ui.css
• https://{domain}/swagger/swagger-ui-standalone-preset.js
• https://{domain}/swagger/swagger-ui-bundle.js

我怀疑，您的实现是错误的。这是在 NET Core 中设置 Swagger UI 的完整 Startup 代码：

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Swashbuckle.AspNetCore.Swagger;
namespace IDGSwaggerDemo
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }
        public IConfiguration Configuration { get; }
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc().SetCompatibilityVersion
            (CompatibilityVersion.Version_2_2);   
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new Info
                {
                    Version = "v1",
                    Title = "Swagger Demo",
                    Description = "Swagger Demo for ValuesController",
                    TermsOfService = "None",
                    Contact = new Contact() { Name = "Joydip Kanjilal",
                    Email = "joydipkanjilal@yahoo.com",
                    Url = "www.google.com"
                }
                });
            });
        }
        public void Configure(IApplicationBuilder app,
       IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            app.UseMvc();
            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
            });
        }
    }
}
