Question

我已经开发了一个自定义异常，我从ServiceStack服务中抛出异常。正确映射状态代码和描述，但内部状态代码和描述是正确的。值始终显示为＆＃39; 0＆＃39;。

以下是我实现异常的方法：

public class TestException : Exception, IHasStatusCode, IHasStatusDescription, IResponseStatusConvertible
{
    private readonly int m_InternalErrorCode;
    private readonly string m_ArgumentName;
    private readonly string m_DetailedError;


    public int StatusCode => 422;
    public string StatusDescription => Message;

    public TestException(int internalErrorCode, string argumentName, string detailedError)
        : base("The request was semantically incorrect or was incomplete.")
    {
        m_InternalErrorCode = internalErrorCode;
        m_ArgumentName = argumentName;
        m_DetailedError = detailedError;
    }

    public ResponseStatus ToResponseStatus()
    {
        return new ResponseStatus
        {
            ErrorCode = StatusCode.ToString(),
            Message = StatusDescription,
            Errors = new List<ResponseError>
            {
                new ResponseError
                {
                    ErrorCode = m_InternalErrorCode.ToString(),
                    FieldName = m_ArgumentName,
                    Message = m_DetailedError
                }
            }
        };
    }
}

当我从ServiceStack服务中抛出异常时 throw new TestException(123, "Thing in error", "Detailed error message");
当我在我的客户端（浏览器/邮递员等）中查看响应时，我获得了一个HTTP状态代码422，其中相应的描述（原因/短语）设置为预期，但内容（当我在标题中指定ContentType = application / json时））看起来像这样......

{
  "statusCode": 0,
  "responseStatus": {
    "errorCode": "422",
    "message": "The request was semantically incorrect or was incomplete.",
    "stackTrace": "StackTrace ommitted for berivity",
    "errors": [
      {
        "errorCode": "123",
        "fieldName": "Thing in error",
        "message": "Detailed error message"
      }
    ]
  }
}

正如您在上面的json响应中所看到的，状态代码为＆＃39; 0＆＃39;。我的问题是 - 如何设置此值？我猜它应该与HTTP响应相同（上例中的422）。

更新：感谢Mythz指出我的答案 我像这样更新了我的响应基类：

public abstract class ResponseBase : IHasResponseStatus, IHasStatusCode
{
    private int m_StatusCode;

    public int StatusCode
    {
        get
        {
            if (m_StatusCode == 0)
            {
                if (ResponseStatus != null)
                {
                    if (int.TryParse(ResponseStatus.ErrorCode, out int code))
                        return code;
                }
            }
            return m_StatusCode;
        }
        set
        {
            m_StatusCode = value;
        }
    }

    public ResponseStatus ResponseStatus { get; set; }
}

ServiceStack仅填充错误响应中的ResponseStatus DTO，statusCode属性里面您的响应DTO是ServiceStack不支持的无关属性（可能是on your Response DTO）处理。自定义例外中实现的StatusCode界面中的IHasStatusCode属性仅用于填充HTTP Status Code。

如何设置ServiceStack ResponseStatus StatusCode？
