  Gzip compression doesn't work in Web Api Core

  Mar 12, 2020 03:21 PM|neoaguil17|LINK

  Hi

  I applied compression in web api core, but I see the same result with and without compression:

  I followed the link:

  as you don't show the response headers, we can not tell if it worked. check that the gzip accept header was sent, also check the content-encoding response header (should be gzip)

  also check that you are not using http/2 which has compression built in and does not use gzip.

  Please do not make the community guess what your doing.  At least share your code, tell us what version of Core you are targeting, explain how you are testing, and the steps to reproduce this behavior..

  Hi

  This is the response...

  I don't see content-encoding: gzip in the response.

  Hi neoaguil17,

  The link article you provied, missed a very important thing for your situation that you have to set EnableForHttps to be true.

          public void ConfigureServices(IServiceCollection services)
          {
              // Configure Compression level
              services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Optimal);
  
              // Add Response compression services
              services.AddResponseCompression(options =>
              {
                  options.EnableForHttps = true;
                  options.Providers.Add<GzipCompressionProvider>();
              });
              services.AddControllers();
  
          }

  Best Regard,

  Yang Shen

  Hi

  I identify that gzip compression doesn't work in iis express, it only works in IIS onpremise or azure appservice.
