How do I use compression with ktor client? I added an "Accept-Encoding: gzip, deflate" header to my requests, and now the responses I get are compressed. How do I make ktor decompress them?

Hi @Marcin Wisniowski, you can use ContentEncoding feature: https://api.ktor.io/1.2.4/io.ktor.client.features.compression/-content-encoding.html

[cy]

Note that you don’t need to set Accept-Encoding header with this feature (it is set automatically)

I'm having a hard time enabling that, where do I enable it? It's not on the https://ktor.io/clients/http-client/features page.

The page is in progress right now. Here is the sample: https://github.com/ktorio/ktor/blob/1e29f25545ec6e366426e1bdfa682d5072246f48/ktor-client/ktor-client-features/ktor-client-encoding/common/test/ContentEncodingTest.kt

Not sure what am I doing wrong 😕

[Marcin Wisniowski]

Do I need some separate artifact for this?

[e5l]

Yep: :ktor-client:ktor-client-encoding-jvm:version

[Marcin Wisniowski]

Works now, thank you!

[e5l]

Awesome 🙂

Is this going to be fixed? gzip() doesn't work, only deflate(). 😐 Guess I will stick with deflate(), apparently it's faster anyway.

in case anybody else comes across this old thread: gzip() is working great for me once i added the deps

[edenman]

i spoke too soon: it’s broken when you get a ResponseException 😭
