在 IIS 上大张旗鼓地发布 web api

Question

在遵循此示例 documentation 之后，我正在尝试弄清楚如何使用 Swagger (SwashBuckle) 发布 .net core 3 API。所以它在本地工作，当我点击 F5 IIS Express 时，会在 http://localhost:8033/index.html 下启动该站点

这是 startup.cs 中的配置代码：

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseAuthorization();

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

            app.UseStaticFiles(new StaticFileOptions
            {
                FileProvider = new PhysicalFileProvider(env.ContentRootPath),
                RequestPath = new PathString("")
            });

            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
                c.DocumentTitle = "TestAPI";
                c.DocExpansion(DocExpansion.None);
                c.RoutePrefix = string.Empty;                   
            });                
        }

接下来，我将 API 发布到本地文件夹，并将文件复制到服务器上的 IIS 文件夹中。如果我打开服务器 API 域，我会得到一个 page can’t be found。我应该使用哪个地址来打开服务器上的 swagger UI？配置中是否缺少某些内容？

您的Swagger 设置没有问题。请不要忘记配置Swagger 生成器，以及Swagger JSON 的cmets 路径。

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo
                {
                    Version = "v1",
                    Title = "ToDo API",
                    Description = "A simple example ASP.NET Core Web API",
                    TermsOfService = new Uri("https://example.com/terms"),
                    Contact = new OpenApiContact
                    {
                        Name = "Shayne Boyer",
                        Email = string.Empty,
                        Url = new Uri("https://twitter.com/spboyer"),
                    },
                    License = new OpenApiLicense
                    {
                        Name = "Use under LICX",
                        Url = new Uri("https://example.com/license"),
                    }
                });
                // Set the comments path for the Swagger JSON and UI.
                var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
                var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
                c.IncludeXmlComments(xmlPath);
            });
        }

另外，请确保服务器已在服务器端安装了 Asp.net 核心托管包。

如果有什么可以帮助的，请随时告诉我。

补充一下，也可能是 PropertyGroup 节点下的 API 项目文件中缺少以下节点。

<RuntimeIdentifiers>win10-x64;</RuntimeIdentifiers>
<AspNetCoreModuleName>AspNetCoreModuleV2</AspNetCoreModuleName>

编辑您的 Startup.cs 文件

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        if (env.IsProduction() || env.IsStaging())
        {
            app.UseExceptionHandler("/Error/index.html");
        }

        // Enable middleware to serve generated Swagger as a JSON endpoint.
        app.UseSwagger(c =>
        {
            c.RouteTemplate = "swagger/{documentName}/swagger.json";
        });

        // Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
        // specifying the Swagger JSON endpoint.
        app.UseSwaggerUI(c =>
        {
            c.RoutePrefix = "swagger";
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "API v1");

            // custom CSS
            c.InjectStylesheet("/swagger-ui/custom.css");
        });

        app.Use(async (ctx, next) =>
        {
            await next();
            if (ctx.Response.StatusCode == 204)
            {
                ctx.Response.ContentLength = 0;
            }
        });


        app.UseHttpsRedirection();

        app.UseRouting();

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

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

        app.UseCors();

    }
