"""Unit tests for the shared ``Base._get_api_key`` JSON-decode resolution.
The base class ``rag.llm.model_meta.Base`` previously returned
``self.api_key`` verbatim. When the API service stored the api_key as a
JSON dict (the format ``api/apps/services/provider_api_service.py:313``
produces for non-string values via ``json.dumps(api_key)``), every subclass
that did not override ``_get_api_key`` and used ``Base._get_raw_model_list``
or its own ``f"Bearer {self._get_api_key()}"`` call sent a malformed
``Authorization: Bearer {"api_key": "sk-xxx", ...}`` header. Real-provider
endpoints 401. The fix mirrors the per-site pattern in VolcEngine /
OpenRouter / NewAPI / LocalAI / Ollama but in the base class so the
6 providers that do not override this method get the same wire-correct
behavior for free: Xinference, HuggingFace, FunASR, NVIDIA, GreenPT,
VLLM, LMStudio, RAGcon, AIMLAPI.
The local-server subclass (Xinference) is used for the unit tests below
because it inherits the base class method directly without any
``__init__`` side effects -- a clean proxy for ``Base._get_api_key``.
The wire-level Bearer contract is verified at the integration level on
two representative subclasses (Xinference for the
``Base._get_raw_model_list`` path; NVIDIA for the per-site
``f"Bearer {self._get_api_key()}"`` pattern).
