response.AppendHeader() 替代 .NET Core

Question

我在派生 ActionFilterAttribute 的 class 的 OnResultExecuting() 方法中使用了 response.AppendHeader("Content-encoding", "gzip");。但它 returns 错误如：

//HttpResponseBase response = filterContext.HttpContext.Response;
HttpResponse response = filterContext.HttpContext.Response;
response.AppendHeader("Content-encoding", "gzip");

'HttpResponse' does not contain a definition for 'AppendHeader' and no accessible extension method 'AppendHeader' accepting a first argument of type 'HttpResponse' could be found (are you missing a using directive or an assembly reference?)

Answer 1

The ASP.NET Core response headers 使用属性来表示大多数常见的 headers.

要在 .NET 6 中设置内容编码，请使用：

response.Headers.ContentEncoding = "gzip";

对于早期版本，您需要使用 the Append extension method:

response.Headers.Append("Content-Encoding", "gzip");
