C# 要应用于非OK响应的属性

如果我有控制器GET方法，例如：

    [HttpGet]
    [Route("accountrecv({accountid})/promisepay", Name = "GetPromisePay")]
    public HttpResponseMessage GetPromisePay(int accountid)
    {
        var query = Request.RequestUri.Query;
        var uri = new Uri(Client.Instance.BaseAddress.ToString() + accountid + "/promisepay" + query);
        var request = new HttpRequestMessage { RequestUri = uri, Method = HttpMethod.Get };
        var response = Client.Instance.SendAsync(request);
        return response.Result;
    }

[NonOKResponse]
[HttpGet]
[Route.......]
public HttpResponseeMessage GetPromisePay(int accountid)
{
//my code
return response.Result //but force it here to return 404 for EVERY response other than 200
}

在

HttpStatusCode

不正常的情况下，如何对所有响应施加行为

我想我会在方法级别创建一个属性，例如：

    [HttpGet]
    [Route("accountrecv({accountid})/promisepay", Name = "GetPromisePay")]
    public HttpResponseMessage GetPromisePay(int accountid)
    {
        var query = Request.RequestUri.Query;
        var uri = new Uri(Client.Instance.BaseAddress.ToString() + accountid + "/promisepay" + query);
        var request = new HttpRequestMessage { RequestUri = uri, Method = HttpMethod.Get };
        var response = Client.Instance.SendAsync(request);
        return response.Result;
    }

[NonOKResponse]
[HttpGet]
[Route.......]
public HttpResponseeMessage GetPromisePay(int accountid)
{
//my code
return response.Result //but force it here to return 404 for EVERY response other than 200
}

我如何定义一个可以在所有GET上使用的属性，以根据某些标准强制执行特定响应？

我相信回答了您的问题。您可以使用

ExceptionFilterAttribute

来处理和管理异常。例如：

public class GeneralExceptionFilterAttribute : ExceptionFilterAttribute 
{
    public override void OnException(HttpActionExecutedContext context)
    {
        context.Response = new HttpResponseMessage(HttpStatusCode.NotFound);
    }
}

听起来你需要一个结果过滤器

为什么不在返回结果之前检查

响应的状态代码呢？因为我有数百个控制器，可能还有数千个方法，我需要对它们应用此i行为或ActionFilter在这里实现工作吗？
