    values = {
            "access_token": access_token,
            "longUrl": longUrl
            }
    response = urllib.request.urlopen(url, urllib.parse.urlencode(values).encode('utf-8'))
    encoding = response.info().get_content_charset('utf-8')
    data = json.loads(response.read().decode(encoding))
    return data["data"]["url"]
