# 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

```go
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

```go
	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.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://bogdanfinn.gitbook.io/open-source-oasis/readme/response-body-encoding-decoding.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
