Response Body Encoding / Decoding

If you are specifying accept-encoding header yourself and you are on a http1 connection than you have to take care of the response body decompression yourself. It is not done automatically.

Only if you are not adding accept-encoding header then the library adds it for you if not explicit disabled and also handles the decompression automatically.

On http2 the automatic decompression should always be in place according to the content-type Header on the Response.

DecompressBody is an exported function you can use. See the following example on how do decompress the response body manually

req, err := http.NewRequest(http.MethodGet, "https://tls.browserleaks.com/json", nil)
if err != nil {
    log.Println(err)
    goreturn
}

req.Header = http.Header{
    "accept":          {"*/*"},
    "accept-encoding": {"gzip"},
    "accept-language": {"de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7"},
    "user-agent":      {"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36"},
    http.HeaderOrderKey: {
        "accept",
        "accept-encoding",
        "accept-language",
        "user-agent",
    },
}

resp, err := client.Do(req)

if err != nil {
    log.Println(err)
    return
}

defer resp.Body.Close()

decomBody := http.DecompressBody(resp)

all, err := ioutil.ReadAll(decomBody)
if err != nil {
    log.Println(err)
    return
}
log.Println(string(all))

It is possible to disable the automatic decompression on http2 by adding the following option to the http client

	tls_client.WithTransportOptions(&tls_client.TransportOptions{
		DisableCompression: true,
	}),

Shared Library & Standalone API

When you are using the shared library or standalone api application the response body will always be decompressed.
