Swashbuckle 自动向生成的 Swagger 文件添加 200 OK 响应

Question

我正在我的 WebApi 2 项目中使用 Swashbuckle 构建 swagger 文档。

我对方法的定义如下：

[HttpPost]
[ResponseType(typeof(Reservation))]
[Route("reservations")]
[SwaggerResponse(HttpStatusCode.Created, Type = typeof(Reservation))]
[SwaggerResponse(HttpStatusCode.BadRequest) ]
[SwaggerResponse(HttpStatusCode.Conflict)]
[SwaggerResponse(HttpStatusCode.NotFound)]
[SwaggerResponse(HttpStatusCode.InternalServerError)]        
public async Task<HttpResponseMessage> ReserveTickets([FromBody] ReserveTicketsRequest reserveTicketRequest)
{
    // ...
    return Request.CreateResponse(HttpStatusCode.Created, response);
}

但是，生成的 Swagger 文件也包含 HTTP 200 OK，尽管它没有在任何地方指定。

/reservations: 
  post: 
    tags: 
      - "Booking"
    operationId: "Booking_ReserveTickets"
    consumes: 
      - "application/json"
      - "text/json"
    produces: 
      - "application/json"
      - "text/json"
    parameters: 
      - 
        name: "reserveTicketRequest"
        in: "body"
        required: true
        schema: 
          $ref: "#/definitions/ReserveTicketsRequest"
    responses: 
      200: 
        description: "OK"
        schema: 
          $ref: "#/definitions/Reservation"
      201: 
        description: "Created"
        schema: 
          $ref: "#/definitions/Reservation"
      400: 
        description: "BadRequest"
      404: 
        description: "NotFound"
      409: 
        description: "Conflict"
      500: 
        description: "InternalServerError"
    deprecated: false

有没有办法摆脱那200 OK？这令人困惑，因为它不是有效的响应。

感谢您的建议。

Answer 1

您可以通过使用SwaggerResponseRemoveDefaults 属性装饰方法来删除默认响应（200 OK）。

Answer 2

正如 vampiire 在他们的评论中指出的那样，SwaggerResponseRemoveDefaults 不再出现在 Swashbuckle 中。现在实现这一点的方法是在方法中同时包含 <response> XML-doc 和 [ProducesResponseType()] 属性：

/// ...
/// <response code="201">Returns the newly reserved tickets</response>
/// <response code="400">If the input parameters are invalid</response>
/// ...
[HttpPost]
[Route("reservations")]
[ProducesResponseType(StatusCodes.Status201Created)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
...
public async Task<HttpResponseMessage> ReserveTickets([FromBody] ReserveTicketsRequest reserveTicketRequest)
{
    ...
}

这将删除默认的 200 响应。它取自 Swashbuckle 5.5.0 和 ASP.NET Core 3.1 上的 Microsoft's Swashbuckle documentation

Answer 3

        services.AddSwaggerGen(c =>
        {
            c.OperationFilter<Api.Swagger.RemoveDefaultResponse>();
        });

   public class RemoveDefaultResponse : IOperationFilter
   {

    public void Apply(OpenApiOperation operation, OperationFilterContext context)
    {
        if (operation.Responses.TryGetValue("200", out var response)) {
            if (response.Description == "Success") {
                operation.Responses.Remove("200");
            }
        }
    }

   }
