常见的想当然

Subclassing Auth to inspect streaming request bodies or handle 401 challenge retries can be done by accessing request.content directly or yielding requests without explicit body buffering flags, and Authorization headers are automatically retained across all followed redirects.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• Subclassing httpx.Auth requires a generator auth_flow yielding requests and receiving responses, preserving 401 challenge responses in history upon retry
• Accessing request.content on streaming requests inside auth_flow raises RequestNotRead unless requires_request_body is set to True
• Accessing response.content on streaming responses inside auth_flow raises ResponseNotRead unless requires_response_body is set to True
• Following redirects strips Authorization headers on cross-origin redirects while preserving them for same-origin destinations
• Client accepts (username, password) tuples as BasicAuth and callable functions as FunctionAuth, while rejecting non-callable types with TypeError
