From 8f4809d1b5ba109342eab95e943c5b35ec2da990 Mon Sep 17 00:00:00 2001 From: Jack Date: Mon, 8 Jun 2026 16:16:56 +0800 Subject: [PATCH] feat: implement POST /api/v1/searchbots/retrieval_test (#15710) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What problem does this PR solve? Implements `POST /api/v1/searchbots/retrieval_test` in the Go API server, aligning with the Python `bot_api.py` counterpart. Also applies security hardening and consistency fixes discovered during CTO-level code review: - **Missing endpoint**: `retrieval_test` was not available in Go, requiring Python fallback - **Security**: Both `chunkHandler` and `searchBotHandler` leaked `err.Error()` to API consumers - **Python alignment**: Default values, empty question handling, and `top_k <= 0` validation differed from Python behavior - **Test gaps**: `chunkHandler.RetrievalTest` had zero unit tests; several edge cases uncovered ## Type of change - [x] New Feature (non-breaking change which adds functionality) - [x] Bug Fix (non-breaking change which fixes an issue) - [x] Refactoring ## Summary ### New Endpoint - `POST /api/v1/searchbots/retrieval_test` — retrieval test with full field support (page, size, top_k, use_kg, cross_languages, keyword, similarity_threshold, vector_similarity_weight) ### New Type - `common.StringSlice` — JSON type that accepts both `"kb1"` and `["kb1", "kb2"]`, matching Python API flexibility ### Security - Both `searchBotHandler` and `chunkHandler` now use `common.Warn()` + generic error messages instead of leaking `err.Error()` to API consumers - All error responses include consistent `"data": nil` shape - `chunkHandler.RetrievalTest` uses interface-based DI (`chunkService`) to enable testability ### Python Alignment - Handler-level defaults align with Python `bot_api.py` (page=1, size=30, top_k=1024, similarity_threshold=0.0, vector_similarity_weight=0.3) - `top_k <= 0` validation matching Python behavior - Empty/whitespace question returns 200 + empty result (matches `chunk_api.py`) - `chunkHandler` `Datasets` field uses `common.StringSlice` for string-or-array flexibility ### Refactoring - `ChunkServiceIface` → `ChunkRetriever`, `chunkSvcIface` → `chunkService` (Go-conventional naming) - Extracted `applyRetrievalDefaults`, `toRetrievalServiceRequest` from handler body - Regex moved to package-level var in `parseRelatedQuestions` - `service.RetrievalTestRequest.Datasets` type changed to `common.StringSlice` - `chunkHandler` now uses consumer-side interface for DI ### Tests - 37 unit tests across both handlers: auth, validation, defaults, StringSlice edge cases, empty/whitespace KbID, service errors, JSON format, `top_k <= 0`, field mapping verification ## Files Changed | File | Change | |------|--------| | `cmd/server_main.go` | Wire new handler + chunkService + difyRetrievalHandler | | `internal/common/json_types.go` | New StringSlice type | | `internal/common/json_types_test.go` | StringSlice tests | | `internal/handler/chunk.go` | Interface-based DI, security, Python alignment, defaults | | `internal/handler/chunk_test.go` | New — 9 comprehensive tests | | `internal/handler/searchbot.go` | New endpoint + refactoring + `top_k <= 0` validation | | `internal/handler/searchbot_test.go` | 18 tests covering all edge cases | | `internal/router/router.go` | Register new route + difyRetrievalHandler | | `internal/service/chunk.go` | Datasets type → StringSlice, Question binding relaxed | 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 --- cmd/server_main.go | 7 +- internal/common/json_types.go | 47 ++ internal/common/json_types_test.go | 114 +++++ internal/handler/chunk.go | 153 +++++- internal/handler/chunk_test.go | 292 ++++++++++++ internal/handler/searchbot.go | 183 +++++++- internal/handler/searchbot_test.go | 414 ++++++++++++++++- internal/router/router.go | 9 +- internal/service/chunk.go | 562 ++++++++++++++++++----- internal/service/chunk_retrieval_test.go | 250 ++++++++++ 10 files changed, 1871 insertions(+), 160 deletions(-) create mode 100644 internal/common/json_types.go create mode 100644 internal/common/json_types_test.go create mode 100644 internal/handler/chunk_test.go create mode 100644 internal/service/chunk_retrieval_test.go diff --git a/cmd/server_main.go b/cmd/server_main.go index 9e60b67768..7221af34cc 100644 --- a/cmd/server_main.go +++ b/cmd/server_main.go @@ -214,10 +214,11 @@ func startServer(config *server.Config) { skillSearchHandler := handler.NewSkillSearchHandler(docEngine) providerHandler := handler.NewProviderHandler(userService, modelProviderService) agentHandler := handler.NewAgentHandler(service.NewAgentService(), fileService) -
