ASP.Net MVCWebApi下集成Swagger UI（.NetCore 和.NetFramework框架）

.NetFramework框架

1. 安装Swashbuckle v5.6.0 Nuget包（目前最新版）

2. 解决方案>属性>生成

3. 添加配置

引入Swashbuckle包，App_Start文件夹会自动添加 SwaggerConfig.cs 类，内部方式默认被注释掉了，取消 c.IncludeXmlComments(GetXmlCommentsPath());该句的注释，并在下方添加方法：

        private static string GetXmlCommentsPath()
        {
            return string.Format(@"{0}\bin\TransactionSearch.xml", AppDomain.CurrentDomain.BaseDirectory);
        }

4. 控制器内编写API接口

5. 浏览器执行

.NetCore框架

1. 引入 Swashbuckle 最新版本

2. 编写文档过滤器

继承 IDocumentFilter 类

public class TagDescriptionsDocumentFilter : IDocumentFilter
    {
        /// <summary>
        /// Apply
        /// </summary>
        /// <param name="swaggerDoc"></param>
        /// <param name="context"></param>
        public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
        {
            swaggerDoc.Tags = new[] {
                new Tag{ Name = "PersonTransaction", Description = "个人交易" },
                new Tag{ Name = "GroupTransaction", Description = "机构交易" }
            };
        }
    }

3. Startup.cs类中注册

 public class Startup
    {
        private readonly IHostingEnvironment _hostingEnv;

        public Startup(IHostingEnvironment env, IConfiguration configuration)
        {
            _hostingEnv = env;
            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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
            
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new Info
                {
                    Title = "xxxx接口",
                    Version = "v1",
                    Description = ""
                });

                // 注释
                c.IncludeXmlComments($"{AppContext.BaseDirectory}{Path.DirectorySeparatorChar}{_hostingEnv.ApplicationName}.xml");

                // Tags描述
                c.DocumentFilter<TagDescriptionsDocumentFilter>();
            });
        }

        // 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.UseExceptionHandler("/api/Home/Error");
            }

            app.UseSwagger(c =>
            {
                c.PreSerializeFilters.Add((swaggerDoc, httpReq) => swaggerDoc.Host = httpReq.Host.Value);
            });

            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "xxxx接口");
            });

            app.UseMvc();
        }
    }
