c# - Swagger 没有生成 swagger.json

Question

我在一个解决方案中有 asp.net 核心 MVC 项目和单独的 WebApi 项目。我正在按照 github 上的文档添加 swagger。这是我的 mvc 项目的 Startup.cs:

public void ConfigureServices(IServiceCollection services)
    {
        //...
        // Adding controllers from WebApi:
        var controllerAssembly = Assembly.Load(new AssemblyName("WebApi"));
        services.AddMvc(o =>
            {
                o.Filters.Add<GlobalExceptionFilter>();
                o.Filters.Add<GlobalLoggingFilter>();
            })
            .AddApplicationPart(controllerAssembly)
            .AddJsonOptions(options =>
            {
                options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
            });

        services.AddSwaggerGen(c =>
        {
            //The generated Swagger JSON file will have these properties.
            c.SwaggerDoc("v1", new Info
            {
                Title = "Swagger XML Api Demo",
                Version = "v1",
            });
        });

        //...
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //...
        app.UseSwagger();
        app.UseSwaggerUI(c =>
        {
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "Swagger XML Api Demo v1");
        });

        //...

        app.UseMvc(routes =>
        {
            // ...
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
    }

以下是核心内容:

WebApi Controller 属性路由:

[Route("api/[controller]")]
public class CategoriesController : Controller
{
    // ...
    [HttpGet]
    public async Task<IActionResult> Get()
    {
        return Ok(await _repo.GetCategoriesEagerAsync());
    }
    // ...
}

当我尝试访问/swagger 时，它找不到/swagger/v1/swagger.json:

我做错了什么？

提前致谢!

我在这个问题上被困了几个小时......我找到了原因......

检查下面的代码!!

..Startup.cs..

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseMvc();
    app.UseSwagger(); // if I remove this line, do not work !
    app.UseSwaggerUi3();
}
