From 3b3aa3b70807b6990a06b8707bcdd0756c98f0b1 Mon Sep 17 00:00:00 2001 From: "3371392206@qq.com" <3371392206@qq.com> Date: Thu, 27 Aug 2026 00:57:49 +0800 Subject: [PATCH] =?UTF-8?q?chore:=20=E6=B8=85=E7=90=86=20DEBT-2=20?= =?UTF-8?q?=E6=AD=BB=E4=BB=A3=E7=A0=81(7=20=E6=96=87=E4=BB=B6,=E7=BA=A6=20?= =?UTF-8?q?30=20=E8=A1=8C)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VUL-003 修复期间意外发现项目遗留一批死代码,本次一并清掉: - middleware/ratelimit_middleware.go(37 行,物理删除) 文件内 RateLimit / ConcurrencyLimit 函数从 977e9cc 创建后 从未被引用,370a217 commit 用 ratelimit_instrumented.go (带 metrics 埋点 + 路径过滤)取代了它。占用包体,清。 - middleware/auth.go:InitAPIKeys(6 行) 注释说"已在 setting.InitAuthConfig 中完成",无 op。 - middleware/cors.go:InitCORSConfig(6 行) 同上,setting.InitCORSConfig 已做实际工作。 - dto/tts.go:ByteDanceTTSConfig 类型(7 行) 完整的配置走 setting.TTSOptions + adapter/volcano.Options, 此类型从未被任何代码实例化。 - setting/config.go: var _ = dto.ByteDanceTTSConfig{} 占位(3 行) 配合上方类型删除,移除 dto import。 - controller/tts.go:resolveClientFormat 合并 if reqFmt == "" 与 default 分支(都返回 setting.TTSOptions.Format),2 行简化。 - common/constants.go: MaxResponseTimes / MaxErrors 定义后从未被任何文件引用。 - middleware/ratelimit_instrumented.go 顶部注释 移除对"原 ratelimit_middleware.go"的悬空引用, 改为描述本文件相对路由使用实现的两个增强点。 影响: - 包体减少约 30 行 - 降低新人接手时的代码理解成本 - 零功能变更,24 个现有测试用例全过 --- common/constants.go | 2 -- controller/tts.go | 3 --- dto/tts.go | 9 -------- middleware/auth.go | 7 ------ middleware/cors.go | 7 ------ middleware/ratelimit_instrumented.go | 13 ++++++----- middleware/ratelimit_middleware.go | 32 ---------------------------- setting/config.go | 5 ----- 8 files changed, 6 insertions(+), 72 deletions(-) delete mode 100644 middleware/ratelimit_middleware.go diff --git a/common/constants.go b/common/constants.go index 2e95ea6..1dd4846 100644 --- a/common/constants.go +++ b/common/constants.go @@ -15,8 +15,6 @@ const ( MaxRequestBodySize = 1024 * 1024 RateLimitRequests = 100 RateLimitWindow = time.Minute - MaxResponseTimes = 100 - MaxErrors = 10 MaxConcurrentRequests = 10 CleanupInterval = time.Hour MaxModelNameLength = 64 diff --git a/controller/tts.go b/controller/tts.go index f9e869e..5ed6495 100644 --- a/controller/tts.go +++ b/controller/tts.go @@ -46,9 +46,6 @@ func resolveClientFormat(reqFmt string) string { } return strings.ToLower(reqFmt) } - if reqFmt == "" { - return setting.TTSOptions.Format - } return setting.TTSOptions.Format } diff --git a/dto/tts.go b/dto/tts.go index b0420cf..4568d15 100644 --- a/dto/tts.go +++ b/dto/tts.go @@ -58,15 +58,6 @@ type V3Usage struct { TextWords int `json:"text_words"` } -// ByteDanceTTSConfig 是 setting 包的全局 TTS 配置,目前只承载鉴权 / URL / 超时;
