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 classDeflatecompressionattribute:actionfilterattribute { Public Override voidonactionexecuted (Httpactionexecutedcontext actcontext) {varContent =actContext.Response.Content; varbytes = Content = =NULL?NULL: Content. Readasbytearrayasync ().            Result; varzlibbedcontent = bytes = =NULL?New byte[0]: compressionhelper.deflatebyte (bytes); ActContext.Response.Content=Newbytearraycontent (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 classCompressionhelper { Public Static byte[] Deflatebyte (byte[] str) {            if(str = =NULL)            {                return NULL; }            using(varOutput =NewMemoryStream ()) {                using (                    varCompressor =NewIonic.Zlib.DeflateStream (output, Ionic.Zlib.CompressionMode.Compress, Ionic.zl Ib. Compressionlevel.bestspeed)) {compressor. Write (str,0, str.                Length); }                returnoutput.            ToArray (); }        }    }

When using the

   [deflatecompression]        publicstring 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
