C# - 将 responseStream 写入 context.response.outputstream

Question

我们的 ASP.net 应用程序需要将一些请求中继到另一台服务器，获取数据并提供数据。我们可以将数据下载到文件中并提供服务，或者直接提供从源服务器到客户端的响应流。数据包括js/css/images/font files/mp3等

HttpWebRequest forwardRequest = (HttpWebRequest)WebRequest.Create(remoteUrl);

                forwardRequest.ContentType = context.Request.ContentType;
                forwardRequest.UserAgent = context.Request.UserAgent;
                forwardRequest.Method = context.Request.HttpMethod;

                //add post check

                HttpWebResponse newResponse = (HttpWebResponse)forwardRequest.GetResponse();

                MemoryStream ms = new MemoryStream();
                newResponse.GetResponseStream().CopyTo(ms);

                context.Response.ContentType = newResponse.ContentType;
                context.Response.StatusCode = 200;
                context.Response.BinaryWrite(ms.GetBuffer());
                ms.Close();

                context.Response.Flush();
                context.Response.Close();
                context.Response.End();

如何直接将 newResponse.GetResponseStream() 传递给 context.Response.OutputStream。

你不能直接传递流，但你可以方便地将一个流写入另一个(这将在内部创建一个读/写循环):

sourceStream.CopyTo(destinationStream);
