How do I enable compression for my API on the linux service plan?-CodePudding

I'm deploying a .net-core web API to the Linux app service plan. I haven't created a DOCKERFILE. Just building production release and deploying. Based on the response headers in production, it appears to be using the Kestrel server. I found in the MS documentation that one can enable compression in the code. This approach seems to work perfectly locally, however I do not see the Content-Encoding header on my web API call while in production.

CodePudding user response：

You can add below code in your startup.cs file. It works for me.

// Configure Compression level
services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Fastest);

// Add Response compression services
services.AddResponseCompression(options =>
{
    options.Providers.Add<GzipCompressionProvider>();
    options.EnableForHttps = true;
});

And you also need add app.UseResponseCompression(); in configure function.

Test Result:
