如果你正在使用最小的API，你可以使用:

app.MapGet("/hello", () => "Hello World!").ExcludeFromDescription();

制作一个滤镜

public class SwaggerTagFilter : IDocumentFilter
{
    public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
    {
        foreach(var contextApiDescription in context.ApiDescriptions)
        {
            var actionDescriptor = (ControllerActionDescriptor)contextApiDescription.ActionDescriptor;
            
            if(!actionDescriptor.ControllerTypeInfo.GetCustomAttributes<SwaggerTagAttribute>().Any() && 
               !actionDescriptor.MethodInfo.GetCustomAttributes<SwaggerTagAttribute>().Any())
            {
                var key = "/" + contextApiDescription.RelativePath.TrimEnd('/');
                swaggerDoc.Paths.Remove(key);
            }
        }
    }
}

创建一个属性

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]
public class SwaggerTagAttribute : Attribute
{
}

在startup.cs中申请

services.AddSwaggerGen(c => {
    c.SwaggerDoc(1, new Info { Title = "API_NAME", Version = "API_VERSION" });
    c.DocumentFilter<SwaggerTagFilter>(); // [SwaggerTag]
});

为你想包含在Swagger JSON中的方法和控制器添加[SwaggerTag]属性

我更倾向于完全删除路径项的字典条目:

var pathsToRemove = swaggerDoc.Paths
                .Where(pathItem => !pathItem.Key.Contains("api/"))
                .ToList();

foreach (var item in pathsToRemove)
{
    swaggerDoc.Paths.Remove(item.Key);
}

使用这种方法，您将不会在生成的swagger中获得“空”项目。json定义。

像@aleha一样，我想在默认情况下排除，这样我就不会意外地暴露端点(默认情况下是安全的)，但使用的是使用OpenApiDocument的Swagger的新版本。

创建一个ShowInSwagger属性

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]
public class ShowInSwaggerAttribute : Attribute
{}

然后创建一个文档过滤器

using Microsoft.AspNetCore.Mvc.Controllers;
using Microsoft.OpenApi.Models;
using Swashbuckle.AspNetCore.SwaggerGen;
using System.Reflection;
using System;
using System.Linq;
using TLS.Common.Attributes;

namespace TLS.Common.Filters
{
    public class ShowInSwaggerFilter : IDocumentFilter
    {
        public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context)
        {
            foreach (var contextApiDescription in context.ApiDescriptions)
            {
                var actionDescriptor = (ControllerActionDescriptor)contextApiDescription.ActionDescriptor;

                if (actionDescriptor.ControllerTypeInfo.GetCustomAttributes<ShowInSwaggerAttribute>().Any() ||
                    actionDescriptor.MethodInfo.GetCustomAttributes<ShowInSwaggerAttribute>().Any())
                {
                    continue;
                }
                else
                {
                    var key = "/" + contextApiDescription.RelativePath.TrimEnd('/');
                    var operation = (OperationType)Enum.Parse(typeof(OperationType), contextApiDescription.HttpMethod, true);

                    swaggerDoc.Paths[key].Operations.Remove(operation);

                    // drop the entire route of there are no operations left
                    if (!swaggerDoc.Paths[key].Operations.Any())
                    {
                        swaggerDoc.Paths.Remove(key);
                    }
                }
            }
        }
    }
}

然后在startup.cs或ConfigureServices中:

public void ConfigureServices(IServiceCollection services)
{
     // other code

    services.AddSwaggerGen(c =>
    {
        c.DocumentFilter<ShowInSwaggerFilter>();
        // other config
    });
}

在SwaggerConfig中添加一行

c.DocumentFilter<HideInDocsFilter>();

...

public class HideInDocsFilter : IDocumentFilter
{
    public void Apply(SwaggerDocument swaggerDoc, SchemaRegistry schemaRegistry, IApiExplorer apiExplorer)
    { 
        var pathsToRemove = swaggerDoc.Paths
            .Where(pathItem => !pathItem.Key.Contains("api/"))
            .ToList();
    
        foreach (var item in pathsToRemove)
        {
            swaggerDoc.Paths.Remove(item.Key);
        }
    }
}

可能会帮助某些人，但在开发(调试)期间，我们喜欢暴露整个控制器和/或动作，然后在生产(发布构建)期间隐藏它们

#if DEBUG
    [ApiExplorerSettings(IgnoreApi = false)]
#else
    [ApiExplorerSettings(IgnoreApi = true)]
#endif
