Swashbuckle.AspNetCore如何描述错误响应模型?

我有一个带有Swashbuckle.AspNetCore软件包的ASP.NET Core v2.1。

我具有以下错误响应模型:

public class ErrorResponse
{
    [JsonProperty(PropertyName = "error")]
    public Error Error { get; set; }
}

public class Error
{
    [JsonProperty(PropertyName = "code")]
    public string Code { get; set; }

    [JsonProperty(PropertyName = "message")]
    public string Message { get; set; }

    [JsonProperty(PropertyName = "target")]
    public string Target { get; set; }

    [JsonProperty(PropertyName = "details")]
    public List<ErrorDetail> Details { get; set; }

    [JsonProperty(PropertyName = "innererror")]
    public InnerError InnerError { get; set; }
}

public class ErrorDetail
{
    [JsonProperty(PropertyName = "code")]
    public string Code { get; set; }

    [JsonProperty(PropertyName = "message")]
    public string Message { get; set; }

    [JsonProperty(PropertyName = "target")]
    public string Target { get; set; }
}

public class InnerError
{
    [JsonProperty(PropertyName = "code")]
    public string Code { get; set; }

    [JsonProperty(PropertyName = "innererror")]
    public InnerError NestedInnerError { get; set; }
}

例如,如果出现问题,我的API端点将返回类型为ErrorResponse的对象,并带有相应的StatusCode:

        if (String.IsNullOrWhiteSpace(token))
        {
            ErrorResponse errorResponse = new ErrorResponse() { Error = new Error() };
            errorResponse.Error.Code = "InvalidToken";
            errorResponse.Error.Target = "token";
            errorResponse.Error.Message = "Token is not specified";
            return new BadRequestObjectResult(errorResponse);
        }

如何使用Swashbuckle.AspNetCore生成适当的文档,因此,如果出现问题,客户端将知道响应格式?

显式响应

如果您需要指定其他状态代码和/或其他响应,或者您的操作返回IActionResult而不是响应DTO,则可以使用ASP.NET Core附带的ProducesResponseTypeAttribute描述显式响应。例如...

[HttpPost("{id}")]
[ProducesResponseType(typeof(Product), 200)]
[ProducesResponseType(typeof(IDictionary<string, string>), 400)]
[ProducesResponseType(500)]
public IActionResult GetById(int id)

因此,您应该添加:
[ProducesResponseType(typeof(ErrorResponse), 400)]
对于那些返回错误的操作,请阅读以下内容:
