我有一个c# ASP。使用Swashbuckle自动生成带有API文档的NET WebAPI应用程序。我想能够从文档中省略某些方法,但我似乎不知道如何告诉Swagger不包括他们在Swagger UI输出。

我觉得这与添加模型或模式过滤器有关,但不清楚要做什么,文档似乎只提供了如何修改方法输出的示例,而不是完全从输出中删除它。

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

其他回答

在swagger文档使用文档过滤器生成后,您可以从该文档中删除“operations”—只需将谓词设置为null(不过,也可能有其他方法可以做到这一点)

下面的示例只允许GET动词—并且是从这个问题中选取的。

class RemoveVerbsFilter : IDocumentFilter
{
    public void Apply(SwaggerDocument swaggerDoc, SchemaRegistry schemaRegistry, IApiExplorer apiExplorer)
    {
        foreach (PathItem path in swaggerDoc.paths.Values)
        {
            path.delete = null;
            //path.get = null; // leaving GET in
            path.head = null;
            path.options = null;
            path.patch = null;
            path.post = null;
            path.put = null;
        }
    }
}

在你狂妄自大的装扮中:

...EnableSwagger(conf => 
{
    // ...

    conf.DocumentFilter<RemoveVerbsFilter>();
});

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。

有人在github上发布了解决方案,所以我要把它粘贴到这里。所有功劳都归他。https://github.com/domaindrivendev/Swashbuckle/issues/153#issuecomment-213342771

首先创建一个Attribute类

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

然后创建一个Document Filter类

public class HideInDocsFilter : IDocumentFilter
{
    public void Apply(SwaggerDocument swaggerDoc, SchemaRegistry schemaRegistry, IApiExplorer apiExplorer)
    {
        foreach (var apiDescription in apiExplorer.ApiDescriptions)
        {
            if (!apiDescription.ActionDescriptor.ControllerDescriptor.GetCustomAttributes<HideInDocsAttribute>().Any() && !apiDescription.ActionDescriptor.GetCustomAttributes<HideInDocsAttribute>().Any()) continue;
            var route = "/" + apiDescription.Route.RouteTemplate.TrimEnd('/');
            swaggerDoc.paths.Remove(route);
        }
    }
}

然后在Swagger配置类中,添加该文档过滤器

public class SwaggerConfig
{
    public static void Register(HttpConfiguration config)
    {
        var thisAssembly = typeof(SwaggerConfig).Assembly;

        config
             .EnableSwagger(c =>
                {
                    ...                       
                    c.DocumentFilter<HideInDocsFilter>();
                    ...
                })
            .EnableSwaggerUi(c =>
                {
                    ...
                });
    }
}

最后一步是在你不希望Swashbuckle生成文档的控制器或方法上添加[HideInDocsAttribute]属性。

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

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
    });
}
