From 5667fad3e13cfa7f605ee8c5a80567c62b0f316a Mon Sep 17 00:00:00 2001 From: bot_dev1 Date: Thu, 6 Aug 2026 16:11:37 +0800 Subject: [PATCH] =?UTF-8?q?fix(#188):=20=E6=8E=A8=E7=90=86=20API=20?= =?UTF-8?q?=E8=B7=AF=E5=BE=84=E8=A7=84=E8=8C=83=E5=8C=96=EF=BC=8C=E6=B6=88?= =?UTF-8?q?=E9=99=A4=E5=8F=8C=20/v1=20=E5=89=8D=E7=BC=80=E5=AF=B9=20nginx?= =?UTF-8?q?=20rewrite=20=E7=9A=84=E9=9A=90=E5=BC=8F=E4=BE=9D=E8=B5=96?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 问题:infer.ts BASE_URL=/v1,fetchModels/chatCompletion 再拼 /v1/* 导致 /v1/v1 双前缀,当前仅靠 nginx 对 /v1/ rewrite 去前缀巧合耦合才通。 修复(前后端+部署一起改): 1. nginx-fba.conf:新增 location /v1/,proxy_pass http://127.0.0.1:30800/ (带末尾 /,不去前缀直接透传),消除对 rewrite 的隐式依赖。 2. infer.ts:BASE_URL 改为空串,调用方统一写 /v1/models、 /v1/chat/completions、/v1/health(fetchHealth 原误用 /health 已修正)。 3. cockpit/index.vue:健康检查改走 infer.ts 的 fetchHealth 封装, 不再裸 fetch('/v1/health'),路径口径统一。 4. ask() latencyMs 由硬编码 0 改为 performance.now() 实测耗时。 5. README 补充推理通道路径约定说明。 验收:浏览器 Network 确认 /v1/models、/v1/chat/completions、 /v1/health 均 200 且无 /v1/v1 请求。(本环境无 pnpm,构建验证转 bot_qa) --- deploy/fba/README.md | 8 +++++++- .../apps/web-antdv-next/src/api/iaop/infer.ts | 12 ++++++++--- .../src/views/iaop/cockpit/index.vue | 12 +++++------ deploy/fba/nginx-fba.conf | 20 +++++++++++++++++++ 4 files changed, 41 insertions(+), 11 deletions(-) diff --git a/deploy/fba/README.md b/deploy/fba/README.md index 2e92e00..bfea716 100644 --- a/deploy/fba/README.md +++ b/deploy/fba/README.md @@ -138,9 +138,15 @@ docker exec -it fba_postgres psql -U postgres -d fba # 进数据库 │ · 6 模块 → views/iaop/*(cockpit/chat/studio/admin) │ · 推理通道 /v1/ → 127.0.0.1:30800(推理服务,独立于 /fba) ├── /fba/ → 127.0.0.1:8001 fba_server(认证/RBAC/系统管理) - └── /v1/ → 127.0.0.1:30800 推理服务(iAOP LLM 网关) + └── /v1/ → 127.0.0.1:30800 推理服务(iAOP LLM 网关,**不去前缀直接透传**) ``` +### 推理通道路径约定(issue #188) +- 推理服务真实路径即 `:30800/v1/*`(`/v1/models`、`/v1/chat/completions`、`/v1/health`)。 +- nginx 反代 `/v1/` 用 `proxy_pass http://127.0.0.1:30800/`(带末尾 `/`,**不去前缀**,直接透传到后端的 `/v1/...`)。 +- 前端 `api/iaop/infer.ts` 的 `BASE_URL` 为空串,调用方统一写 `/v1/models`、`/v1/chat/completions`、`/v1/health`,**不再出现 `/v1/v1` 双前缀**,也不依赖 nginx rewrite 去前缀的巧合耦合。 +- nginx location 片段见 `deploy/fba/nginx-fba.conf`。 + ### 组件落点 - 受控源码:`fba-ui-src/`(fastapi-best-architecture-ui 工程,apps/web-antdv-next) - 构建流水线:`build-ui.sh`(pnpm install → build → artifacts/fba-ui-dist.tar.gz) diff --git a/deploy/fba/fba-ui-src/apps/web-antdv-next/src/api/iaop/infer.ts b/deploy/fba/fba-ui-src/apps/web-antdv-next/src/api/iaop/infer.ts index 3314809..a5e88f5 100644 --- a/deploy/fba/fba-ui-src/apps/web-antdv-next/src/api/iaop/infer.ts +++ b/deploy/fba/fba-ui-src/apps/web-antdv-next/src/api/iaop/infer.ts @@ -8,8 +8,12 @@ * * 推理服务为 iAOP 独立通道(不要求 FBA JWT),故用原生 fetch 封装, * 统一超时 / 错误信息 / 结果结构;FBA requestClient 仅用于 /fba/* 接口。 + * + * issue #188:推理服务真实路径即 :30800/v1/*,nginx 反代 /v1/ 不去前缀直接透传, + * 故 BASE_URL 为空串,调用方统一写 /v1/models、/v1/chat/completions, + * 避免出现 /v1/v1 双前缀对 nginx rewrite 的隐式耦合。 */ -const BASE_URL = '/v1';
