def get_access_token(client_id, client_secret, token_url, auth_url, redirect_uri):
    from oauthlib.oauth1 import OAuth1
    from requests import post

    # Create an OAuth1 object with client credentials
    client = OAuth1(client_id, client_secret)

    # Make a request to the authorization URL to get a request token
    auth_response = post(auth_url, auth=client)

    # Extract the request token and token secret from the response
    request_token = auth_response.json().get('request_token')
    request_token_secret = auth_response.json().get('request_token_secret')

    # Redirect the user to the authorization URL with the request token
    # This part is omitted for simplicity, but in a real application, you would redirect the user here

    # After user authorization, exchange the request token for an access token
    client.update(
        resource_owner_key=request_token,
        resource_owner_secret=request_token_secret
    )

    # Make a request to the token URL to get the access token
    token_response = post(token_url, auth=client)
    token = token_response.json()

    # Return the access token and token secret
    return token
