压缩筛选器与asp.net MVC中的ExceptionHandlerFilter冲突

action-filter exception-handling asp.net-mvc

Mike Flynn · 技术社区 · 7 年前

我没有得到我的异常处理命中时,我有压缩过滤器的行动,他们是一个错误。请求未返回响应。如果我删除压缩过滤器,那么它返回的错误数组就可以了。我怎样才能跳过一个错误的压缩过滤器,或者让它第二次命中?

 [HttpPost, CompressAttribute]
 public virtual ActionResult Builder()

全球.asax

GlobalConfiguration.Configuration.Filters.Add(new ExceptionHandlingAttribute());

压缩过滤器

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class CompressAttribue : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
                var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
                if (string.IsNullOrEmpty(encodingsAccepted)) return;

                encodingsAccepted = encodingsAccepted.ToLowerInvariant();
                var response = filterContext.HttpContext.Response;

                if (encodingsAccepted.Contains("gzip"))
                {
                    response.AppendHeader("Content-encoding", "gzip");
                    response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
                }
                else if (encodingsAccepted.Contains("deflate"))
                {
                    response.AppendHeader("Content-encoding", "deflate");
                    response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
                }
        }
    }

我把它移到 OnActionExecuted 因为它包含了一个异常属性。

public override void OnActionExecuted(ActionExecutedContext filterContext)
        {
            base.OnActionExecuted(filterContext);

            if (filterContext.Exception == null)
            {
                var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];
                if (!encodingsAccepted.IsBlank())
                {
                    encodingsAccepted = encodingsAccepted.ToLowerInvariant();
                    var response = filterContext.HttpContext.Response;

                    if (encodingsAccepted.Contains("gzip"))
                    {
                        response.AppendHeader("Content-encoding", "gzip");
                        response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
                    }
                    else if (encodingsAccepted.Contains("deflate"))
                    {
                        response.AppendHeader("Content-encoding", "deflate");
                        response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
                    }
                }
            }
        }
