Controlled by: - ``cache_jwk_set``: Set to ``True`` (the default) to enable this cache. When enabled, the JWK Set is fetched from the network only when the cache is empty or expired. - ``lifespan``: Time in seconds before the cached JWK Set expires. Defaults to ``300`` (5 minutes). Must be greater than 0. **Tier 2 — Signing key cache** (disabled by default): Caches individual signing keys (looked up by ``kid``) using an LRU cache with **no time-based expiration**. Keys are evicted only when the cache reaches its maximum size. Controlled by: - ``cache_keys``: Set to ``True`` to enable this cache. Defaults to ``False``. - ``max_cached_keys``: Maximum number of signing keys to keep in the LRU cache. Defaults to ``16``. :param uri: The URL of the JWKS endpoint. :type uri: str :param cache_keys: Enable the per-key LRU cache (Tier 2). :type cache_keys: bool :param max_cached_keys: Max entries in the signing key LRU cache. :type max_cached_keys: int :param cache_jwk_set: Enable the JWK Set response cache (Tier 1). :type cache_jwk_set: bool :param lifespan: TTL in seconds for the JWK Set cache. :type lifespan: float :param headers: Optional HTTP headers to include in requests. :type headers: dict or None :param timeout: HTTP request timeout in seconds. :type timeout: float :param ssl_context: Optional SSL context for the request. :type ssl_context: ssl.SSLContext or None N)httphttpszInvalid JWKS URI scheme z(: only 'http' and 'https' are supported.rz/Lifespan must be greater than 0, the input is "")maxsize) r schemelowerruri jwk_set_cacheheaderstimeout ssl_contextrrget_signing_key) selfr cache_keysmax_cached_keys cache_jwk_setlifespanrrrrrs K/var/www/html/truck-me/venv/lib/python3.12/site-packages/jwt/jwks_client.py__init__zPyJWKClient.__init__sj ?G #%%++- * *"*6*5!" 15  & 1}&EhZqQ"-X!6D !%D  @i@AUAUVO#2D c tjj|j|j}tjj ||j |j5}tj|}ddd|j |j j#S#1swY2xYw#ttf$r5}t|tr|jtd|d|d}~wwxYw)aeFetch the JWK Set from the JWKS endpoint.
