From 58912d4ac52429ba240d19fc011d45cf16c83c01 Mon Sep 17 00:00:00 2001 From: yangjianbo Date: Tue, 10 Feb 2026 08:59:30 +0800 Subject: [PATCH] =?UTF-8?q?perf(backend):=20=E4=BD=BF=E7=94=A8=20gjson/sjs?= =?UTF-8?q?on=20=E4=BC=98=E5=8C=96=E7=83=AD=E8=B7=AF=E5=BE=84=20JSON=20?= =?UTF-8?q?=E5=A4=84=E7=90=86?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 将 API 网关热路径中的 json.Unmarshal+json.Marshal 替换为 gjson 零拷贝查询和 sjson 精准写入： - unwrapV1InternalResponse 性能提升 22x（4009ns→182ns），内存分配减少 28.5x - unwrapGeminiResponse、extractGeminiUsage、estimateGeminiCountTokens、ParseGeminiRateLimitResetTime 改为接收 []byte 使用 gjson 提取 - ParseGatewayRequest 的 model/stream/metadata/thinking/max_tokens 改用 gjson 类型安全提取 - Handler 层（sora/openai）改用 gjson 提取字段、sjson 注入/修改字段，移除 map[string]any 中间变量 - Sora Client 响应解析改用 gjson ForEach 遍历，减少内存分配 - 新增约 100 个单元测试用例，所有改动函数覆盖率 >85% Co-Authored-By: Claude Opus 4.6 ---
