.Net标准/核心版本的system.web.http.HttpError [英] .Net standard/core version of system.web.http.HttpError

问题描述

从.net Framework迁移到.net Standard/Core时我遇到了HttpError类.除了Compatability Shim只是临时解决方案之外，我在.net核心/标准中找不到任何等效项.

While migrating form .net Framework to .net Standard/Core I came across the HttpError class. I can't find any equivalent in .net core/standard except of the Compatability Shim which is just a temporary solution.

您知道是否有官方替代品吗?也许API发生了变化，并且有一种新的最佳实践可以代替HttpError使用.

Do you know if there is an official replacement for it? Maybe the API has changed and there is a new best practice to use instead of HttpError.

谢谢！

推荐答案

HttpError对象提供了一种一致的方式来在响应正文中返回错误信息.在asp.net Core Web API中，您可以定义一个基本的ApiResponse类，例如:

The HttpError object provides a consistent way to return error information in the response body. In asp.net Core Web API, you can define a base ApiResponse class like :

public class ApiResponse
{
    public int StatusCode { get; }

    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    public string Message { get; }

    public ApiResponse(int statusCode, string message = null)
    {
        StatusCode = statusCode;
        Message = message ?? GetDefaultMessageForStatusCode(statusCode);
    }

    private static string GetDefaultMessageForStatusCode(int statusCode)
    {
        switch (statusCode)
        {
            ...
            case 404:
                return "Resource not found";
            case 500:
                return "An unhandled error occurred";
            default:
                return null;
        }
    }
}

您还可以派生此类来定义更特定的预定义错误类型，请参考

You can also derive this class to define more specific predefined error types, please refer to this and this article for more details and code sample .

从2.1版开始，它添加了对 RFC 7807 – HTTP API的问题详细信息的支持.从HTTP API返回机器可读错误响应的标准格式:

From version 2.1 ,it added support for RFC 7807 – Problem Details for HTTP APIs as a standardized format for returning machine readable error responses from HTTP APIs:
