HOW

ゴール: Register synchronous and asynchronous request and response event hooks in httpx Client and AsyncClient to transform headers, validate status codes, and intercept multi-hop redirects
パッケージ: httpx 0.28.1
シンボル: httpx.AsyncClient
httpx.Client
httpx.HTTPStatusError
httpx.MockTransport
httpx.Request
httpx.Response
環境: python
作成日: 2026-08-28T03:48:19Z

httpx.Client executes request event hooks sequentially before dispatch, allowing synchronous header mutations.
httpx.Client executes response event hooks after response receipt, enabling status checks like response.raise_for_status() to propagate HTTPStatusError.
httpx.Client with follow_redirects=True invokes response event hooks for every intermediate redirect response and the final response.
httpx.Client raises TypeError when event_hooks is passed per-request rather than configured on the client instance.
httpx.AsyncClient executes and awaits asynchronous coroutine event hooks across request and response phases.
httpx.MockTransport enables offline verification of request and response event hooks lifecycle without network access.
