Note: in most cases, you should use [`huggingface_hub.utils.build_hf_headers`] instead. This method is only useful if you want to retrieve the token for other purposes than sending an HTTP request. If `HF_OIDC_RESOURCE` is set (Trusted Publishers, typically in CI), a short-lived token obtained via OIDC token exchange takes precedence. Otherwise the token is retrieved from the `HF_TOKEN` environment variable, then from the token file in the Hugging Face home folder. Returns None if user is not logged in. To log in, use [`login`] or `hf auth login`. OAuth tokens obtained with the browser-based login come with a refresh token: when such a token is close to expiry, it is transparently refreshed and persisted before being returned. Note: if `HF_OIDC_RESOURCE` is set but the OIDC token exchange fails, this raises instead of returning `None`, opting into OIDC is explicit, so a failure surfaces as a clear error rather than a silent fallback. Returns: `str` or `None`: The token, `None` if it doesn't exist. )_get_token_from_oidc_get_token_from_environment_get_token_from_file_refreshed_get_token_from_google_colabr) get_tokenr3:s>,  * & ( ( * ) + + * ( ) ) r2chtrtrdSt5trtcdddS ddlm}ddlm}n#t$rYddddSwxYw | d}t|an#|j $rtjddaYn_|j$rt ddaYn8|$r1}tjdt%|d daYd}~nd}~wwxYwd atcdddS#1swxYwYdS) zGet token from Google Colab secrets vault using `google.colab.userdata.get(...)`.

Best-effort: never raises. OAuth tokens obtained with the browser-based login are stored with a `refresh_token` and an `expires_at` timestamp (see `_save_token`). When the active token is one of them and about to expire, exchange the refresh token for a new access token and persist it. Any other token is returned unchanged.
