Using gzip or deflate compression in the ASP. NET Web API

Compression is a simple and effective way to reduce the size and responsiveness of response packets.

So how do I compress the ASP. I'll use a very popular library for compression/decompression called the DotNetZip library . This library can be obtained using nuget packages

Now, we have implemented the deflate compression actionfilter.

public class Deflatecompressionattribute:actionfilterattribute {public override void onactionexecuted (httpact            Ionexecutedcontext actcontext) {var content = ActContext.Response.Content; var bytes = Content = = null? Null:content. Readasbytearrayasync ().            Result; var zlibbedcontent = bytes = = null?            New Byte[0]: compressionhelper.deflatebyte (bytes);            ActContext.Response.Content = new Bytearraycontent (zlibbedcontent);            ActContext.Response.Content.Headers.Remove ("Content-type");            ACTCONTEXT.RESPONSE.CONTENT.HEADERS.ADD ("content-encoding", "deflate");            ACTCONTEXT.RESPONSE.CONTENT.HEADERS.ADD ("Content-type", "Application/json"); Base.        OnActionExecuted (Actcontext); }}public class Compressionhelper {public static byte[] Deflatebyte (byte[] str) {if (str            = = null) {return null; } using (Var output = new MemoryStream ()) {using (var compressor = new Ionic.Zlib.DeflateStre AM (output, Ionic.Zlib.CompressionMode.Compress, Ionic.Zlib.CompressionLevel.BestSpe ed)) {Compressor. Write (str, 0, str.                Length); } return output.            ToArray (); }        }    }

When using the

   [Deflatecompression]        public string Get (int id)        {            return "OK" +id;        }

Of course, if you use gzip compression, you only need to

New Ionic.Zlib.DeflateStream (instead

New Ionic.Zlib.GZipStream (, and then

ACTCONTEXT.RESPONSE.CONTENT.HEADERS.ADD ("content-encoding", "deflate");

ACTCONTEXT.RESPONSE.CONTENT.HEADERS.ADD ("content-encoding", "gzip");
Can, after I test,

Deflate compression is smaller than gzip-compressed code, so it is recommended to use deflate compression
