1.安装NuGet包

2.配置

3.运行测试

参考博客：

一 安装NuGet包

包名：Swashbuckle.AspNetCore

二 配置

Use this method to add services to the container.        public void ConfigureServices(IServiceCollection services)        {            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);            ////注册Swagger生成器，定义一个和多个Swagger 文档            //services.AddSwaggerGen(c =>            //{            //    c.SwaggerDoc("v1", new Info { Title = "My API_info", Version = "v1_info" });            //});            //注册Swagger生成器，定义一个和多个Swagger 文档            services.AddSwaggerGen(c =>            {                c.SwaggerDoc("v1", new Info                {                    Version = "v1",                    Title = "yilezhu's API",                    Description = "A simple example ASP.NET Core Web API",                    TermsOfService = "None",                    Contact = new Contact                    {                        Name = "依乐祝",                        Email = string.Empty,                        Url = "http://www.cnblogs.com/yilezhu/"                    },                    License = new License                    {                        Name = "许可证名字",                        Url = "http://www.cnblogs.com/yilezhu/"                    }                });                // 为 Swagger JSON and UI设置xml文档注释路径                var basePath = Path.GetDirectoryName(typeof(Program).Assembly.Location);//获取应用程序所在目录（绝对，不受工作目录影响，建议采用此方法获取路径）                var xmlPath = Path.Combine(basePath, "WebApplicationCoreAPIStudy4.xml");                c.IncludeXmlComments(xmlPath);            });                   }        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.        public void Configure(IApplicationBuilder app, IHostingEnvironment env)        {            if (env.IsDevelopment())            {                app.UseDeveloperExceptionPage();            }            else            {                app.UseHsts();            }            app.UseHttpsRedirection();            app.UseMvc();            //启用中间件服务生成Swagger作为JSON终结点            app.UseSwagger();            //启用中间件服务对swagger-ui，指定Swagger JSON终结点            app.UseSwaggerUI(c =>            {                c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1_endpoint");                //加上后，访问地址：https://localhost:44389                //c.RoutePrefix = string.Empty;//访问地址：https://localhost:44389/swagger                  });        }    }}

三 运行测试
