.net core Swagger 过滤部分Api

因为场景需要,要把某些特定的api过滤掉,不允许显示在swaggerui里,

具体操作步骤: 分为三步

步骤1: 创建Attribute   

     /// <summary>
     /// ignore some api on swagger.json
     /// </summary>
     [AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = false)]
     public class SwaggerIgnoreAttribute : Attribute
     {

     }

步骤2:创建IDocumentFilter的实现类XXXFileter

 /// <summary>
    /// 过滤具备SwaggerIgnore特性的api
    /// </summary>
    public class SwaggerIgnoreFilter : IDocumentFilter
    {

        public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
        {

            var ignoreApis = context.ApiDescriptions.Where(wh => wh.ActionAttributes().Any(any => any is SwaggerIgnoreAttribute));
            if (ignoreApis != null)
            {
                foreach (var ignoreApi in ignoreApis)
                {
                    swaggerDoc.Paths.Remove("/" + ignoreApi.RelativePath);
                }
            }

        }

    }

步骤3:StartUp类中 Swagger的Config中使用过滤器

 services.AddSwaggerGen(
                options =>
                {
                    options.DocumentFilter<SwaggerIgnoreFilter>();
                });
