HOW

ゴール: Configure transport-level retries in httpx without assuming Client-level retries, read/5xx retries, or unlimited phase timeouts
パッケージ: httpx 0.28.1
シンボル: httpx.HTTPTransport
httpx.Client
httpx.Timeout
httpx.ConnectError
httpx.ConnectTimeout
httpx.ReadTimeout
httpx.WriteTimeout
httpx.PoolTimeout
httpx.BaseTransport
環境: python
作成日: 2026-08-16T12:50:34Z

assert httpx.Client does not accept retries kwarg, raising TypeError
assert httpx.HTTPTransport retries default to 0 and must be explicitly configured
assert HTTPTransport(retries=N) retries ConnectError and ConnectTimeout exactly N times (N+1 total attempts)
assert HTTPTransport(retries=N) never retries ReadTimeout, ReadError, or HTTP 5xx responses
assert Timeout four fields (connect, read, write, pool) map to transport extensions and specific TimeoutException subclasses
assert application-level status and read retries require custom BaseTransport wrapping
