from streamlit.server.Server import Server
import streamlit as st

def get_headers():
    # Hack to get the session object from Streamlit.

    current_server = Server.get_current()
    if hasattr(current_server, '_session_infos'):
        # Streamlit < 0.56
        session_infos = Server.get_current()._session_infos.values()
    else:
        session_infos = Server.get_current()._session_info_by_id.values()

    # Multiple Session Objects?
    for session_info in session_infos:
        headers = session_info.ws.request.headers
        st.write(headers)
#    return headers

Thank a lit, @andfanilo

You should now use the dedicated _get_websocket_headers() streamlit/streamlit#5457
