c# - Nswag 在相同的 Http 状态代码中指定多个响应示例？

Question

我需要通过 C# 设置一些具有相同 http 状态代码的响应示例。

我研究了帖子
https://blog.rsuter.com/nswag-tutorial-implement-a-custom-operation-processor-to-define-redoc-code-samples/

但我还是不知道。

我能怎么做 ？
请给我一些提示...

// i want to create json , like this.
responses:
        '404':
          description: please , let It worked...
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/TestModel'
              examples:
                success :
                  summary: Example of a successful response
                  value:
                    code : 1
                    message : "test message 1"
                success2 :
                  summary: Example of a successful response2
                  value:
                    code : 2
                    message: "test message 2"

更新：我使用 NSwag，像这样
我需要让代码 404 有两个示例响应

/// <summary></summary>
/// <remarks></remarks>
/// <response code="200"></response>
/// <response code="404">Message 1</response>
/// <response code="404">Message 2</response>   // <---- error will occur , 
[HttpPost]
[ProducesResponseType(typeof(CreateIdentificationResponse), 200)]
[ProducesResponseType(typeof(ErrorResponse), 404)]
[ProducesResponseType(typeof(ErrorResponse), 404)]
public IActionResult Post(){
}

Answer 1

你可以这样的SwaggerResponse属性：

[HttpGet("")]
[SwaggerResponse(200, "Myfile content", typeof(MyFile))]
[SwaggerResponse(404, "Could not find file", typeof(MyFile))]
public async Task<IActionResult> YouAction()

它将记录 2 个可能的响应状态代码：200和404. 您可以根据需要应用任意数量的这些属性

Answer 2

我得到答案~~~

// using
// [ExampleAttribute (nameof(MyError.MyErrorFieldName))]

public class ExampleAttribute : OpenApiOperationProcessorAttribute
{
    public ExampleAttribute(string errorField)
        : base(typeof(ExampleAppender))
    {
        var type = typeof(GeneralError);
        var field = type.GetField(errorField, BindingFlags.Public | BindingFlags.Static);       
        var error = field?.GetValue(null) as IMyError;
        Parameters = new object[] { error };
    }

    private class ExampleAppender : IOperationProcessor
    {
        private readonly IMyError _error;
        public ExampleAppender(IMyError error)
        {
            _error = error ?? throw new ArgumentNullException(nameof(error));
        }

        public bool Process(OperationProcessorContext context)
        {
            var openApiResponses = context.OperationDescription.Operation.Responses;
            openApiResponses.TryAdd(((int)_error.StatusCode).ToString(), new OpenApiResponse());
            var apiResponse = openApiResponses[((int)_error.StatusCode).ToString()];
            if (!string.IsNullOrEmpty(_error.StatusCode.ToString()))
            {
                apiResponse.Description = _error.StatusCode.ToString();
            }

            apiResponse.Content.TryAdd(MediaTypeNames.Application.Json, new OpenApiMediaType() { Schema = JsonSchema.FromType<MyErrorResponse>() });
            var openApiMediaType = apiResponse.Content[MediaTypeNames.Application.Json];
            openApiMediaType.Examples.TryAdd( 
                _error.Description ?? "",
                new OpenApiExample()
                {
                    Description = _error.Description,
                    Value = new MyErrorResponse(_error.Message)
                });
            return true;
        }
    }
}

遵循 OpenApiOperationProcessorAttribute
