swagger 不显示 HttpGet 查询参数

Question

我正在使用 swagger 开发 asp.net core webapi(6.0)。当我运行应用程序 HttpGet 方法时，参数摘要在 swagger 中不可见。例如 Id、StoreId、DateFrom、DateTo 摘要不会在 swagger 中显示。请指教

 /// <summary>
    /// Get product details.
    /// </summary>
    /// <remarks>Fetches product.</remarks>
    /// <param name="parameters"></param>
    /// <returns></returns>
    /// <response code="200">Successful Response</response>
    /// <response code="400">Bad Request</response>
    /// <response code="401">Unauthorized</response>
    /// <response code="424">Failed Dependency</response>
    /// <response code="500">Internal Server Error</response>
    public async Task<IActionResult> GetProduct([FromQuery] Parameter parameters)
        {
            var repo = await Repository.GetAllAsync(parameters);
            return Ok()
        }



public class Parameter
{
    /// <summary>
    /// Product Id
    /// </summary>
    public string? Id { get; set; }
    /// <summary>
    /// Optional Parameter. If supplied, result set will be restricted to the products from the supplied store alone
    /// </summary>
    public int? StoreId { get; set; }
    /// <summary>
    /// Optional Parameter.
    /// </summary>
    public DateTime? DateFrom { get; set; }
    /// <summary>
    /// Optional Parameter.
    /// </summary>
public DateTime? DateTo { get; set; }
}

XML comments可用于向 swagger UI 添加参数。

首先GenerateDocumentationFile在 .csproj 文件中启用生成 xml 文档文件，该文件将在 swagger json 生成中使用。

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <GenerateDocumentationFile>true</GenerateDocumentationFile>
    <NoWarn>$(NoWarn);1591</NoWarn>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
  </ItemGroup>

</Project>

然后将 swagger 服务配置为IncludeXmlComments来自类型化的 xml 文档文件：

//builder.Services.AddSwaggerGen();
builder.Services.AddSwaggerGen(options =>
{
    // using System.Reflection;
    var xmlFilename = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
    options.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, xmlFilename));
});

结果：
