Question

我正在使用一个actionfilter来压缩我对来自控制器内部动作的响应

这是我的动作过滤器：

Public Class CompressAttribute 
        Inherits ActionFilterAttribute 
        Implements IActionFilter 
        Public Overrides Sub OnActionExecuting(filterContext As ActionExecutingContext) 
            Dim request As HttpRequestBase = filterContext.HttpContext.Request 

            Dim acceptEncoding As String = request.Headers("Accept-Encoding") 

            If String.IsNullOrEmpty(acceptEncoding) Then 
                Return 
            End If 
            acceptEncoding = acceptEncoding.ToUpperInvariant() 

            Dim response As HttpResponseBase = filterContext.HttpContext.Response 
            If acceptEncoding.Contains("DEFLATE") Then 

                response.AppendHeader("Content-encoding", "deflate") 

                response.AppendHeader("Vary", "Accept-Encoding") 
                response.Filter = New WebCompressionFilter(response.Filter, CompressionMode.Compress) 

            ElseIf acceptEncoding.Contains("GZIP") Then 
               response.AppendHeader("Content-encoding", "gzip") 
                response.AppendHeader("Vary", "Accept-Encoding") 
                response.Filter = New WebCompressionFilter(response.Filter, CompressionMode.Compress) 
            End If 
        End Sub 
    End Class

我将它应用于我的控制者内部的行动。

问题是它在开发环境中的桌面上运行得很好但在我的实时服务器上（在共享主机中）它没有gzip编码。

相反，它会进行分块传输编码....

为什么？

您是否有任何理由在自己的代码中手动执行此操作？ IIS中已存在此功能：

确保您在计算机上有installed动态内容压缩（链接中的项目符号5）和enabled it in IIS。完成这些步骤后，我从未遇到任何问题。一旦你这样做，也不再需要你的属性，IIS将隐式处理静态和动态内容。维护更少的代码总是一件好事！

gzip压缩与动作过滤器无法正常工作
