接口 Swagger 部分Web API的隐藏

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 Swagger
            services.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
