使用Swashbuckle Asp.Net Core for ReDoc添加x徽标供应商扩展

Question

我正在使用swagger.json文件（由Swashbuckle生成）供ReDoc显示API文档。

我需要什么：  将x-logo供应商扩展名添加到使用Swashbuckle（Swashbuckle.AspNetCore.SwaggerGen库）生成的swagger json中，以便ReDoc UI在like this的左上角显示徽标

问题： 我可以将x-log添加到swagger.json文件中，但是将其添加到文件的错误部分。它必须位于info部分中。

这就是我添加x-logo

所做的

• 创建了如下所示的文档过滤器

    public class XLogoDocumentFilter : IDocumentFilter
        {
            public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
            {
              swaggerDoc.Extensions["x-logo"] = new { url = "https://URL/of/the/logo", altText = "Company Logo" };
            }

        }

• 以
的形式将过滤器添加到SwaggerDoc

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

});

实际

    {
      "swagger": "2.0",
      "info": {
        "version": "v1",
        "title":"Sample REST API"
      },
      "x-logo": {
        "url": "https://rebilly.github.io/ReDoc/petstore-logo.png",
        "altText": "Aimia Logo"
      }
    }

预期

    {
      "swagger": "2.0",
      "info": {
        "version": "v1",
        "title":"Sample REST API",
        "x-logo": {
          "url": "https://rebilly.github.io/ReDoc/petstore-logo.png",
          "altText": "Aimia Logo"
        }
      },

    }

非常感谢在x-logo中添加swagger.json文件正确部分的帮助或建议。

.NET Core 2.2及更高版本

public class XLogoDocumentFilter : IDocumentFilter
{
    public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context)
    {
        // need to check if extension already exists, otherwise swagger 
        // tries to re-add it and results in error  
        if (!swaggerDoc.Info.Extensions.ContainsKey("x-logo"))
            swaggerDoc.Info.Extensions.Add("x-logo", new OpenApiObject
            {
                {"url", new OpenApiString("https://www.petstore.com/assets/images/logo.png")},
                {"backgroundColor", new OpenApiString("#FFFFFF")},
                {"altText", new OpenApiString("PetStore Logo")}
            });
    }

}

输入问题后，我自己找到了解决方案。与其直接将扩展名添加到swaggerDoc，不如将扩展名添加到swaggerDoc.Info对象。

public class XLogoDocumentFilter : IDocumentFilter
        {
            public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
            {   
              // need to check if extension already exists, otherwise swagger 
              // tries to re-add it and results in error  
              if (!swaggerDoc.Info.Extensions.ContainsKey("x-logo"))
              {
                 swaggerDoc.Info.Extensions.Add("x-logo", new {
                    url = "https://URL/To/The/Logo",
                    altText = "Logo",
                });
              }           

            }

        }

较新版本的Swashbuckle在SwaggerDoc设置中支持此功能：

c.SwaggerDoc("v1", new OpenApiInfo
{
  Title = ApiDescription,
  Version = "v1",
  Extensions = new Dictionary<string, IOpenApiExtension>
    {
      {"x-logo", new OpenApiObject
        {
           {"url", new OpenApiString("https://blah.com/logo")},
           { "altText", new OpenApiString("The Logo")}
        } 
      }
    }
});
