.NET Core Swagger 的分组使, 以及相同Action能被多个分组公用,同时加载出尚未分组的数据出来

1.本文章参考 点击链接跳转 改写的 一对多分组模式。需要一对一的可以参考

2.本文主要讲的是 一对多 分组公用, 同时把尚未分组的加载出来

3.效果演示GIF图:

具体操作代码如下:

1.在项目创建一个目录（ApiGroup），然后创建三个类，分别为ApiGroupAttribute.cs（控制器特性），ApiGroupNames.css（系统分组枚举），GroupInfoAttribute.cs（给系统分组枚举值增加相关信息的特性，这个主要是用于在Swagger分组时可关联Title，Version，Description值）

ApiGroupAttribute.cs代码如下

 /// <summary>
    /// 系统分组特性
    /// </summary>
    public class ApiGroupAttribute : Attribute
    {
        public ApiGroupAttribute(params ApiGroupNames[] name)
        {
            GroupName = name;
        }
        public ApiGroupNames[] GroupName { get; set; }
    }

ApiGroupNames.cs代码如下

/// <summary>
    /// 系统分组枚举值
    /// </summary>
    public enum ApiGroupNames
    {
        [GroupInfo(Title = "All", Description = "All接口", Version = "")]
        All = 0,
        [GroupInfo(Title = "尚未分组", Description = "尚未分组相关接口", Version = "")]
        NoGroup = 1,
        [GroupInfo(Title = "登录认证", Description = "登录认证相关接口", Version = "")]
        Login = 2,
        [GroupInfo(Title = "IT", Description = "登录认证相关接口", Version = "")]
        It = 3,
        [GroupInfo(Title = "人力资源", Description = "登录认证相关接口", Version = "")]
        Hr = 4,
        [GroupInfo(Title = "系统配置", Description = "系统配置相关接口", Version = "")]
        Config = 5
    }

GroupInfoAttribute.cs代码如下

public class GroupInfoAttribute : Attribute
    {
        public string Title { get; set; }
        public string Version { get; set; }
        public string Description { get; set; }
    }

******** 打开Startup.cs文件修改ConfigureServices方法（为了方便查看，只列出关于Swagger分组的关键代码）*************

//1.0 ConfigureServices 里面swagger 的设置

#region swagger

            var openApiInfo = new OpenApiInfo
            {
                Version = "v1",
                Title = "WebApi",
                Description = "A simple example ASP.NET Core Web API",
                TermsOfService = new Uri("https://www.cnblogs.com/goodluckily/"),
                Contact = new OpenApiContact
                {
                    Name = "雨太阳",
                    Email = string.Empty,
                    Url = new Uri("https://www.cnblogs.com/goodluckily/")
                },
                License = new OpenApiLicense
                {
                    Name = "许可证名字",
                    Url = new Uri("https://www.cnblogs.com/goodluckily/")
                }
            };

            services.AddSwaggerGen(c =>
            {
                #region 分组方案二

                //遍历ApiGroupNames所有枚举值生成接口文档，Skip(1)是因为Enum第一个FieldInfo是内置的一个Int值
                typeof(ApiGroupNames).GetFields().Skip(1).ToList().ForEach(f =>
                {
                    //获取枚举值上的特性
                    var info = f.GetCustomAttributes(typeof(GroupInfoAttribute), false).OfType<GroupInfoAttribute>().FirstOrDefault();
                    openApiInfo.Title = info?.Title;
                    openApiInfo.Version = info?.Version;
                    openApiInfo.Description = info?.Description;
                    c.SwaggerDoc(f.Name, openApiInfo);
                });

                //判断接口归于哪个分组
                c.DocInclusionPredicate((docName, apiDescription) =>
                {
                    if (!apiDescription.TryGetMethodInfo(out MethodInfo method)) return false;
                    //1.全部接口
                    if (docName == "All") return true;
                    //反射拿到控制器分组特性下的值
                    var actionlist = apiDescription.ActionDescriptor.EndpointMetadata.FirstOrDefault(x => x is ApiGroupAttribute);
                    //2.得到尚未分组的接口***************
                    if (docName == "NoGroup") return actionlist == null ? true : false;
                    //3.加载对应已经分好组的接口
                    if (actionlist != null)
                    {
                        //判断是否包含这个分组
                        var actionfilter = actionlist as ApiGroupAttribute;
                        return actionfilter.GroupName.Any(x => x.ToString().Trim() == docName);
                    }
                    return false;
                });

                #endregion

                //添加授权

                //认证方式，此方式为全局添加

                var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
                var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
                c.IncludeXmlComments(xmlPath, true);
            });
#endregion

2.0 Configure 里面swagger 的设置

 #region Swagger

            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.RoutePrefix = "swagger";

                #region 分组方案二
                //遍历ApiGroupNames所有枚举值生成接口文档，Skip(1)是因为Enum第一个FieldInfo是内置的一个Int值
                typeof(ApiGroupNames).GetFields().Skip(1).ToList().ForEach(f =>
                {
                    //获取枚举值上的特性
                    var info = f.GetCustomAttributes(typeof(GroupInfoAttribute), false).OfType<GroupInfoAttribute>().FirstOrDefault();
                    c.SwaggerEndpoint($"/swagger/{f.Name}/swagger.json", info != null ? info.Title : f.Name);
                });
                #endregion

                //swagger 默认折叠
                //c.DocExpansion(Swashbuckle.AspNetCore.SwaggerUI.DocExpansion.None);

                //MiniProfiler用的
                c.IndexStream = () => GetType().GetTypeInfo().Assembly.GetManifestResourceStream("WebApi.index.html");
            });

#endregion

然后你F6生成一下，没出错的话，就Ctrl+F5看看，正常的话就会在Swagger右上角看到分组了。

 *********************具体在 WeatherForecastController 里面的使用***************

1.单个Action特性 [ApiGroup(ApiGroupNames.Config)]

2.多个Action特性 [ApiGroup(ApiGroupNames.Login,ApiGroupNames.It)]

..............

具体详细的Controller代码如下

    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : Controller
    {

        private readonly ILogger<WeatherForecastController> _logger;

        private readonly IHttpContextAccessor _accessor;
        public WeatherForecastController(ILogger<WeatherForecastController> logger, IHttpContextAccessor accessor)
        {
            _logger = logger;
            _accessor = accessor;
        }
        /// <summary>
        /// 多分组共用请求
        /// </summary>
        /// <returns></returns>
        //[ProducesResponseType(201)]
        //[ProducesResponseType(400)]

        [HttpGet("getLoginAndIT")]
        [ApiGroup(ApiGroupNames.Login,ApiGroupNames.It)]
        public IActionResult GetLoginAndIT()
        {
            return  Json("GetLoginAndIT ok");
        }

        [HttpGet("getConfig")]
        [ApiGroup(ApiGroupNames.Config)]
        public IActionResult GetConfig()
        {
            return Json("Config ok");
        }

        [HttpGet("getHr")]
        [ApiGroup(ApiGroupNames.Hr)]

        public IActionResult GetHr()
        {
            return Json("Hr ok");
        }

        [HttpGet("getIt")]
        [ApiGroup(ApiGroupNames.It)]

        public IActionResult GetIt()
        {
            return Json("GetIt ok");
        }
        /// <summary>
        /// 获取Miniprofiler Index的 Script (尚未分组的)
        /// </summary>
        /// <returns></returns>
        [HttpGet("getMiniprofilerScript")]
        public IActionResult getMiniprofilerScript()
        {
            var htmlstr = MiniProfiler.Current.RenderIncludes(_accessor.HttpContext);
            var script = htmlstr.Value;
            return Json(script);
        }
    }
