1.写一个隐藏接口特性表示 

using Microsoft.AspNetCore.Mvc.ApiExplorer;
using Microsoft.OpenApi.Models;
using Swashbuckle.AspNetCore.SwaggerGen;using System.Web.Http.Description;namespace JiaTongInterface.Filter
{public class SwaggerApi : Swashbuckle.AspNetCore.SwaggerGen.IDocumentFilter{/// <summary>/// 隐藏swagger接口特性标识/// </summary>[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]public class HideApiAttribute : System.Attribute{}public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context){foreach (Microsoft.AspNetCore.Mvc.ApiExplorer.ApiDescription description in context.ApiDescriptions){if (description.TryGetMethodInfo(out MethodInfo method)){if (method.ReflectedType.CustomAttributes.Any(t => t.AttributeType == typeof(HideApiAttribute))|| method.CustomAttributes.Any(t => t.AttributeType == typeof(HideApiAttribute))){string key = "/" + description.RelativePath;if (key.Contains("?")){int idx = key.IndexOf("?", System.StringComparison.Ordinal);key = key.Substring(0, idx);}swaggerDoc.Paths.Remove(key);}}}}}}

2.在porgram.cs中加入option.DocumentFilter<SwaggerApi>();

builder.Services.AddSwaggerGen(option =>
{var xmlFilename = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";option.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, xmlFilename), true);option.DocumentFilter<SwaggerApi>();
});

3.使用方法，在controlller前加入[SwaggerApi.HideApi]即可实现隐藏

4.效果 这里就看不到接口了
