fix(proxy): write an access-log line for every request the proxy surface answers - #1260
Conversation
The AuthenticatedKey extractor short-circuits ahead of the handler, which is where every access-log line is written, so a 401 (no credential, unknown key, disabled or expired key, any JWT rejection) and a JWT 403 left no access-log record. The extractor now writes the line itself on every rejection, gated by observability.access_log like every other line. It carries method, path, status, latency, request id and the error class; no key id and never the presented credential. aisix_auth_decisions_total and the aisix::auth denial lines are unchanged.

171-188: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winThe access-log serializer and the authentication-denial path promise these fields, but no inspected test asserts all of them on this extractor path. The new test can therefore pass if the denial record has the wrong method, raw path,
error_kind, or error message. This leaves a material regression in the behavior the test is intended to protect undetected.🤖 Prompt for AI Agents

…spatch GET /v1/models, the A2A agent card, the OAuth protected-resource documents, the unrouted-path 404 and the router's automatic 405 answered the caller without ever writing an access-log line. Each now writes one with the fields known at that point (method, raw path, status, latency, request id, and the key id where the route authenticated). /livez and /readyz still write none: they are platform probes, not client traffic. The 405 keeps axum's Allow header.

@coderabbitai Good call on the auth-denial nitpick. d2f89d0 makes both new e2e files assert the method and raw path on every line, alongside the count, status and credential checks. I left |

Some requests on the proxy listener got an answer but wrote no access-log line. Access-log lines are written at the tail of each dispatching handler, and these requests never get there. Two groups were missing:
AuthenticatedKeyextractor short-circuits before the handler runs, so a 401 (no credential, unknown key, disabled or expired key, a rejected JWT) or a JWT entitlement 403 was recorded only inaisix_auth_decisions_totaland on theaisix::authlog line, and the scanner-probe shapes of that line are logged at debug.GET /v1/models(every outcome, including 200), the A2A agent card (/a2a/:agent/.well-known/agent-card.json), the OAuth protected-resource documents (/.well-known/oauth-protected-resource[/mcp]), the 404 for a path no route serves, and the router's automatic 405 when a known path gets the wrong method.Leaving auth failures out of the access log was a deliberate choice meant to keep scanner probes out of the default log. That choice is reversed here: every request the proxy surface answers now gets exactly one line, and keeping the volume down is the job of the log pipeline or of
observability.access_log.How each group is fixed:
/v1/models, files/batches/fine-tuning, videos,/mcp(non-anonymous) and/a2a.reject::emit_unrouted_access_log.method_not_allowed_fallback, which keeps axum'sAllowheader.Every new line carries only what is known at that point: method, raw path, status, latency and request id, plus
api_key_idonly where the route had already authenticated the caller (the model list and the agent card). Auth-denial lines also carryerror_kindand the fixed error message. No line ever contains any part of a presented credential.observability.access_log: falsesuppresses all of them./livezand/readyzstill write no line, because they are platform probes, not client traffic.aisix_auth_decisions_total, theaisix::authdenial lines, request metrics and usage events are all unchanged.Behaviour change: with the access log on (the default), you will now see one
proxy request completedline atinfofor each of these requests:An internet-facing gateway will log noticeably more. Operators can filter these lines in their log pipeline or turn the access log off with
observability.access_log: false. None of the existing access-log fields change meaning.Audit of the proxy listener's paths that answer before or outside dispatch:
