过期链接的 HTTP 状态代码

Question

伙计们，在一定时间内过期的链接的正确状态代码是什么？

我想在过期后发送 404，但也许有更好的 http 状态要发送。

链接示例：

mysite/dir/062011/file.exe （<-仅在2011年6月工作）

谢谢

Answer 1

410 "消失"怎么样？
请参阅：http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

Answer 2

410 Gone
The requested resource is no longer available at the server and no forwarding
address is known. This condition is expected to be considered permanent.

Answer 3

我在尝试在 C# Web API 中验证过期的验证码时选择了 410 Gone 。我使用 REST API 教程作为参考 https://www.restapitutorial.com/httpstatuscodes.html

    /// <summary>
    /// Verify email address
    /// </summary>
    /// <param name="verificationCode">Verification Code for ownership of an email address</param>
    /// <returns>Verify Email Update Api Response</returns>
    [HttpPut]
    [Route("{verificationCode}/verify-email-update")]
    [ResponseType(typeof(VerifyEmailChangeApiResponse))]
    public async Task<IHttpActionResult> VerifyEmailUpdate(Guid verificationCode)
    {
        var response = await this.emailVerificationService
            .VerifyEmailUpdate(verificationCode)
            .ConfigureAwait(false);
        switch (response.Result)
        {
            case VerifyEmailUpdateApiResultType.Ok:
                return this.Ok(response);
            case VerifyEmailUpdateApiResultType.EmailAddressAlreadyVerified:
                return this.Content(HttpStatusCode.Conflict, response);
            case VerifyEmailUpdateApiResultType.Expired:
                return this.Content(HttpStatusCode.Gone, response);
            case VerifyEmailUpdateApiResultType.UnknownProblem:
                return this.Content(HttpStatusCode.BadRequest, response);
        }
        return this.Ok(response);
    }
