如何从Golang的http响应中读取压缩数据

I have a http response which is gzipped.

resp, err := client.Do(req)
    if err != nil {
        return "", err
    }

    defer resp.Body.Close()

    if resp.StatusCode == http.StatusOK {
        var buf bytes.Buffer


    }

How can I ungzipped it and parse it into my struct?

I saw a question like this: Reading gzipped HTTP response in Go

but it output the response into a standard output. Also the example runs into error, the

reader, err = gzip.NewReader(response.Body)

returns err as "EOF". How can I debug this?

    I solved this by reading this code: https://gist.github.com/xyproto/f4915d7e208771f3adc4

    here is the code which helped me.

    // Write gunzipped data to a Writer
    func gunzipWrite(w io.Writer, data []byte) error {
        // Write gzipped data to the client
        gr, err := gzip.NewReader(bytes.NewBuffer(data))
        defer gr.Close()
        data, err = ioutil.ReadAll(gr)
        if err != nil {
            return err
        }
        w.Write(data)
        return nil
    }
