背景

Swagger是目前最受欢迎的REST APIs文档生成工具，同时也是API的在线测试工具。功能强大谁用谁知道。我就不用在这里推广它了。今天要解决的问题是：如果让一些特定的API接口在Swagger中不显示，即从Swagger中过滤掉一些不想展示的接口？通常我们使用Swagger都是通过指定要扫描的包或者扫描具有某些注解的Controller，来生成API，那么如果这其中还想过滤掉一些特定API怎么做呢？

实现方法

1、添加特性，隐藏swagger接口特性标识

  /// <summary>////// </summary>/// <param name="swaggerDoc"></param>/// <param name="context"></param>public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context){foreach (ApiDescription apiDescription in context.ApiDescriptions){if (apiDescription.TryGetMethodInfo(out MethodInfo method)){if (method.ReflectedType.CustomAttributes.Any(t => t.AttributeType == typeof(HiddenApiAttribute))|| method.CustomAttributes.Any(t => t.AttributeType == typeof(HiddenApiAttribute))){string key = "/" + apiDescription.RelativePath;if (key.Contains("?")){int idx = key.IndexOf("?", System.StringComparison.Ordinal);key = key.Substring(0, idx);}swaggerDoc.Paths.Remove(key);}}}}}

2、添加过滤器，自定义Swagger隐藏过滤器

  /// <summary>/// 隐藏swagger接口特性标识/// </summary>[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]public class HiddenApiAttribute : System.Attribute{}

3、修改SwaggerConfig，注入过滤器

#region Swaggerservices.AddSwaggerGen(c =>{c.SwaggerDoc("v1", new Info{Version = "v1",Title = "接口文档",Description = "接口文档-基础",TermsOfService = "https://example.com/terms",Contact = new Contact{Name = "XXX1111",Email = "XXX1111@qq.com",Url = "https://example.com/terms"},License = new License{Name = "Use under LICX",Url = "https://example.com/license",}});c.SwaggerDoc("v2", new Info{Version = "v2",Title = "接口文档",Description = "接口文档-基础",TermsOfService = "https://example.com/terms",Contact = new Contact{Name = "XXX2222",Email = "XXX2222@qq.com",Url = "https://example.com/terms"},License = new License{Name = "Use under LICX",Url = "https://example.com/license",}});c.OperationFilter<HttpHeaderOperationFilter>();c.DocumentFilter<HiddenApiFilter>();var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);c.IncludeXmlComments(xmlPath);c.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, $"CompanyName.ProjectName.ICommonServer.xml"));});#endregion Swagger

测试

   /// <summary>/// 检测帐号是不已存在/// </summary>/// <param name="account">(必填)帐号或手机号    Data=true 已存在,Data=false 不存在</param>/// <returns>测试</returns>[HttpGet, Route("existAccount")][ApiExplorerSettings(GroupName = "v2")]//[HiddenApi]public R<bool> ExistAccount([FromQuery] string account){return R<bool>.Suc(true);}
