# CORS / CSP / 安全 Header 全套审计与改进
**审计日期**: 2026-06-15
**审计人**: Claude(满载跑批)
**关联**: [[风险跟踪表]] / [[后端架构]] / [[外部系统集成]]
---
## 📌 1. 现状盘点
### 1.1 后端 CORS 配置(`backend/app/main.py:363`)
```python
app.add_middleware(
CORSMiddleware,
allow_origins=settings.cors_origins_list, # 逗号分隔的列表
allow_credentials=True,
allow_methods=["GET", "POST", "PUT", "DELETE", "OPTIONS"],
allow_headers=["Authorization", "Content-Type", "X-Employee-Id"],
)
```
**当前 `cors_origins`**:
- 默认: `localhost:5173,5174,5175`(开发)
- 生产: `itsupport.servyou.com.cn`(.env.production)
### 1.2 Nginx 安全头(`nginx.conf` + `nginx-nas.conf`)
**已有**:
```nginx
add_header X-Content-Type-Options "nosniff" always;
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-XSS-Protection "1; mode=block" always;
```
**缺失**:
- `Strict-Transport-Security` (HSTS)
- `Content-Security-Policy` (CSP)
- `Referrer-Policy`
- `Permissions-Policy`
- `Cross-Origin-*` 系列
### 1.3 问题清单
| # | 问题 | 严重度 | 风险 |
|---|---|---|---|
| C-1 | CORS `allow_origins` 默认含 `*`(环境切换不当会泄露) | 🟠 | 跨域未授权 |
| C-2 | CORS 没限制 `expose_headers`(前端拿不到 trace_id) | 🟡 | 排障不便 |
| C-3 | CORS `max_age` 未设(每次预检) | 🟢 | 性能 |
| C-4 | nginx 缺 HSTS | 🟠 | 中间人降级 |
| C-5 | nginx 缺 CSP | 🟠 | XSS |
| C-6 | nginx 缺 Referrer-Policy | 🟡 | 信息泄露 |
| C-7 | nginx 缺 Permissions-Policy | 🟡 | 设备 API 滥用 |
| C-8 | nginx 缺 COOP/COEP | 🟡 | 跨源攻击 |
| C-9 | `/api/wecom/callback` 没限 IP | 🟡 | 恶意回调 |
| C-10 | 4 前端没 CSP meta(防 XSS) | 🟠 | XSS |
---
## 📌 2. CORS 改进
### 2.1 后端 - 精细化 CORS
**新建 `backend/app/utils/cors_config.py`**:
```python
from typing import List
from app.config import settings
def build_cors_config() -> dict:
"""根据环境构建 CORS 配置"""
is_prod = settings.backend_env == "production" # 需新增环境变量
if is_prod:
# 生产:严格白名单
origins = [
o.strip() for o in settings.cors_origins.split(",")
if o.strip() and not o.startswith("*")
]
return {
"allow_origins": origins,
"allow_credentials": True,
"allow_methods": ["GET", "POST", "PUT", "DELETE", "PATCH", "OPTIONS"],
"allow_headers": [
"Authorization",
"Content-Type",
"X-Employee-Id",
"X-Request-ID", # trace_id
"X-CSRF-Token", # CSRF 防护
"X-Agent-Id", # 坐席 ID
],
"expose_headers": [
"X-Request-ID", # 暴露 trace_id
"X-RateLimit-Remaining", # 限流剩余
"X-RateLimit-Reset", # 限流重置
],
"max_age": 600, # 10 分钟预检缓存
}
# 开发:宽松
return {
"allow_origins": settings.cors_origins_list,
"allow_credentials": True,
"allow_methods": ["*"],
"allow_headers": ["*"],
"expose_headers": ["*"],
"max_age": 3600,
}
```
**更新 `main.py`**:
```python
from app.utils.cors_config import build_cors_config
cors_config = build_cors_config()
app.add_middleware(
CORSMiddleware,
**cors_config,
)
```
### 2.2 新增环境变量
**`backend/app/config.py`**:
```python
# 新增
backend_env: str = "development" # development / production
```
**`.env.production`**:
```bash
BACKEND_ENV=production
CORS_ORIGINS=https://itsupport.servyou.com.cn
```
### 2.3 CORS 验证脚本
```bash
# 验证 CORS 头
curl -I -X OPTIONS \
-H "Origin: https://itsupport.servyou.com.cn" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: Authorization" \
http://localhost:8000/api/v1/auth/login
# 期望响应:
# Access-Control-Allow-Origin: https://itsupport.servyou.com.cn
# Access-Control-Allow-Credentials: true
# Access-Control-Max-Age: 600
```
---
## 📌 3. Nginx 安全 Header 完整套
### 3.1 完整版 nginx.conf(替换安全头部分)
```nginx
# =================================================================
# 安全响应头配置(全部)
# =================================================================
# 1. HSTS - 强制 HTTPS(2 年,包含子域名)
add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;
# 2. CSP - 内容安全策略(严格版,API 网关除外)
# 注意:API 路径不要 CSP(纯 JSON),只 HTML 路径需要
location /itdesk/ {
# 基础 CSP
add_header Content-Security-Policy "
default-src 'self';
script-src 'self' 'unsafe-inline' 'unsafe-eval' https://res.wx.qq.com;
style-src 'self' 'unsafe-inline';
img-src 'self' data: blob: https: http:;
font-src 'self' data:;
connect-src 'self' https://qyapi.weixin.qq.com wss://* https://*.servyou-it.com;
media-src 'self' blob:;
object-src 'none';
frame-ancestors 'none';
base-uri 'self';
form-action 'self';
upgrade-insecure-requests;
" always;
alias /usr/share/nginx/html/itdesk/;
# ...
}
# 3. 防 MIME 嗅探
add_header X-Content-Type-Options "nosniff" always;
# 4. 防点击劫持(更严:拒绝所有 frame 嵌入)
add_header X-Frame-Options "DENY" always;
# 5. XSS 过滤器(现代浏览器已废弃,保留向后兼容)
add_header X-XSS-Protection "0" always; # 0 = 关闭(CSP 已接管)
# 6. Referrer 策略(API 不发送 referrer,HTML 限制来源)
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
# 7. Permissions Policy(禁用不用的设备 API)
add_header Permissions-Policy "
camera=(),
microphone=(),
geolocation=(),
payment=(),
usb=(),
magnetometer=(),
gyroscope=(),
accelerometer=()
" always;
# 8. 跨源隔离
add_header Cross-Origin-Opener-Policy "same-origin" always;
add_header Cross-Origin-Embedder-Policy "require-corp" always;
add_header Cross-Origin-Resource-Policy "same-origin" always;
# 9. 服务器信息隐藏
server_tokens off; # 隐藏 nginx 版本
# 10. API 路径特殊头(API 不需要 CSP,但要 CORS 友好)
location /api/ {
# 移除 CSP(API 返回 JSON,不要 CSP)
more_clear_headers "Content-Security-Policy";
# API 也加 HSTS
add_header Strict-Transport-Security "max-age=63072000; includeSubDomains" always;
add_header X-Content-Type-Options "nosniff" always;
add_header Cache-Control "no-store" always; # API 禁止缓存
proxy_pass http://backend_api/;
# ...
}
```
### 3.2 完整版 nginx-nas.conf(同上,Cloudflare 适配)
```nginx
# Cloudflare Tunnel 已经在外层 HTTPS,这里加全头
add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-Frame-Options "DENY" always;
add_header X-XSS-Protection "0" always;
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
add_header Permissions-Policy "camera=(), microphone=(), geolocation=(), payment=()" always;
add_header Cross-Origin-Opener-Policy "same-origin" always;
add_header Cross-Origin-Embedder-Policy "require-corp" always;
add_header Cross-Origin-Resource-Policy "same-origin" always;
server_tokens off;
```
---
## 📌 4. 前端 CSP Meta(双保险)
### 4.1 4 前端 `index.html` 加 meta CSP
**`frontend-admin/index.html`**:
```html
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-Content-Type-Options" content="nosniff">
<!-- CSP - 与 nginx 头保持一致 -->
<meta http-equiv="Content-Security-Policy" content="
default-src 'self';
script-src 'self' 'unsafe-inline' 'unsafe-eval' https://res.wx.qq.com;
style-src 'self' 'unsafe-inline';
img-src 'self' data: blob: https: http:;
font-src 'self' data:;
connect-src 'self' https://qyapi.weixin.qq.com wss://* https://*.servyou-it.com;
media-src 'self' blob:;
object-src 'none';
frame-ancestors 'none';
base-uri 'self';
form-action 'self';
">
<meta name="referrer" content="strict-origin-when-cross-origin">
<meta http-equiv="Permissions-Policy" content="
camera=(), microphone=(), geolocation=(), payment=()
">
<title>IT 智能服务台 - 管理后台</title>
</head>
```
### 4.2 CSP 报告模式(先观察,再强制)
**第 1 步: Report-Only 模式(2 周)**:
```nginx
add_header Content-Security-Policy-Report-Only "..." always;
```
**第 2 步: 收集违规报告**(发到 `/api/v1/csp-report`)
**第 3 步: 改 enforce 模式**:
```nginx
add_header Content-Security-Policy "..." always; # 不带 Report-Only
```
---
## 📌 5. 企微回调 IP 限制
### 5.1 企微回调 IP 段(从企微文档)
| 段 | 用途 |
|---|---|
| `101.226.103.0/24` | 企微上海 |
| `101.226.108.0/24` | 企微上海 |
| `140.207.54.0/24` | 企微上海 |
| `140.207.61.0/24` | 企微深圳 |
| `183.192.192.0/18` | 企微通用 |
| `121.51.130.0/24` | 企微广州 |
**注意**: 实际范围可能变更,需查官方文档。
### 5.2 nginx 限制
```nginx
location = /api/wecom/callback {
# 只允许企微 IP 段
allow 101.226.103.0/24;
allow 101.226.108.0/24;
allow 140.207.54.0/24;
allow 140.207.61.0/24;
allow 183.192.192.0/18;
allow 121.51.130.0/24;
# 内网允许(开发)
allow 127.0.0.1;
allow 10.0.0.0/8;
allow 172.16.0.0/12;
allow 192.168.0.0/16;
deny all;
proxy_pass http://backend_api/api/wecom/callback;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
```
---
## 📌 6. 速率限制(补充)
### 6.1 现有方案
`backend/app/main.py` 已用 `slowapi` 全局限流,默认 60/分钟。
### 6.2 精细化建议
| 路径 | 限制 | 理由 |
|---|---|---|
| `/api/v1/auth/login` | 5/分钟/IP | 防爆破 |
| `/api/v1/auth/otp` | 3/分钟/IP | 防 OTP 暴力 |
| `/api/v1/conversations` | 60/分钟/agent | 正常业务 |
| `/api/v1/messages` | 120/分钟/agent | 消息多 |
| `/api/wecom/callback` | 不限 | 企微回调 |
**配置示例**:
```python
# backend/app/main.py
from slowapi import Limiter
from slowapi.util import get_remote_address
limiter = Limiter(key_func=get_remote_address)
@app.post("/api/v1/auth/login")
@limiter.limit("5/minute")
async def login(...):
...
```

## 📌 7. 测试与验证
### 7.1 安全 Header 在线检测
```bash
# Mozilla Observatory
https://observatory.mozilla.org/analyze/itsupport.servyou.com.cn
# Security Headers
https://securityheaders.com/?q=itsupport.servyou.com.cn
# SSL Labs(SSL 评估)
https://www.ssllabs.com/ssltest/analyze.html?d=itsupport.servyou.com.cn
```
### 7.2 CORS 自动化测试
**`scripts/cors-test.sh`**(新建):
```bash
#!/bin/bash
# CORS 自动化测试
set -e
API="http://localhost:8000"
ORIGIN="http://localhost:5173"
echo "=== 1. 预检请求 ==="
curl -s -I -X OPTIONS \
-H "Origin: $ORIGIN" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: Authorization" \
"$API/api/v1/auth/login" | head -20
echo ""
echo "=== 2. 实际请求 ==="
curl -s -I -H "Origin: $ORIGIN" "$API/api/v1/health" | head -20
echo ""
echo "=== 3. 期望 ==="
echo "Access-Control-Allow-Origin: $ORIGIN"
echo "Access-Control-Allow-Credentials: true"
```
### 7.3 安全 Header 验证
**`scripts/security-headers-test.sh`**(新建):
```bash
#!/bin/bash
# 安全 Header 验证
URL="${1:-http://localhost}"
echo "=== 检查安全头 ==="
HEADERS=$(curl -sI "$URL/")
check_header() {
local header=$1
local expected=$2
if echo "$HEADERS" | grep -qi "^$header:"; then
echo "✅ $header: $(echo "$HEADERS" | grep -i "^$header:" | cut -d':' -f2- | xargs)"
else
echo "❌ $header: 缺失"
fi
}
check_header "Strict-Transport-Security"
check_header "X-Content-Type-Options" "nosniff"
check_header "X-Frame-Options"
check_header "Content-Security-Policy"
check_header "Referrer-Policy"
check_header "Permissions-Policy"
```

## 📌 1. 现状盘点
| 镜像 | Dockerfile | 基础 | 估计大小 | 多阶段 |
|---|---|---|---|---|
| backend | `backend/Dockerfile` | `python:3.12-slim` | ~250 MB | ✅ |
| frontend-agent | `frontend-agent/Dockerfile` | `nginx:1.27-alpine` | ~50 MB | ✅ |
| frontend-h5 | `frontend-h5/Dockerfile` | `nginx:1.27-alpine` | ~50 MB | ✅ |
| postgres | (用官方) | `postgres:16-alpine` | ~80 MB | — |
| redis | (用官方) | `redis:7-alpine` | ~30 MB | — |
| nginx | (用官方) | `nginx:1.27-alpine` | ~40 MB | — |
**总估计镜像大小**:`~500 MB`(4 业务 + 2 数据库)
---
## 📌 2. backend Dockerfile 审计
### 2.1 当前实现
```dockerfile
FROM python:3.12-slim AS builder
RUN apt-get update && apt-get install -y --no-install-recommends \
gcc libpq-dev libjpeg-dev zlib1g-dev curl
COPY requirements.txt .
RUN pip install --no-cache-dir --timeout 120 --retries 5 \
-i https://pypi.tuna.tsinghua.edu.cn/simple/ \
--trusted-host pypi.tuna.tsinghua.edu.cn \
-r requirements.txt
FROM python:3.12-slim
RUN apt-get update && apt-get install -y --no-install-recommends libpq5 curl
COPY --from=builder /usr/local/lib/python3.12/site-packages /usr/local/lib/python3.12/site-packages
COPY --from=builder /usr/local/bin /usr/local/bin
COPY . .
EXPOSE 8000
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]
```
### 2.2 问题清单
| # | 问题 | 严重度 | 优化 |
|---|---|---|---|
| B-1 | ⚠️ **装 curl** — 但 P1-3 已改 healthcheck 用 Python urllib | 🟡 | 删 curl(节省 1MB) |
| B-2 | ⚠️ **不用非 root 用户** | 🟠 中 | 加 `USER appuser` |
| B-3 | ⚠️ **没 HEALTHCHECK** — 交给 docker-compose | 🟡 | Dockerfile 也加 |
| B-4 | ⚠️ **COPY . . 太宽** — 含 .git / tests / docs | 🟡 | 加 .dockerignore |
| B-5 | 🟢 pip 装到 venv(更隔离) | 🟢 | 已用 site-packages |
| B-6 | ⚠️ **没用 BuildKit cache mount** | 🟡 | 加 `--mount=type=cache` |
| B-7 | ⚠️ **PyPI 用清华源** — 公司内网可,但生产建议官方 | 🟡 | 评估 |
### 2.3 优化版
```dockerfile
# syntax=docker/dockerfile:1.7
FROM python:3.12-slim AS builder
# 创建非 root 用户
RUN groupadd -r appuser && useradd -r -g appuser appuser
WORKDIR /app
# 系统依赖(只装构建期需要的)
RUN --mount=type=cache,target=/var/cache/apt,sharing=locked \
--mount=type=cache,target=/var/lib/apt,sharing=locked \
apt-get update && \
apt-get install -y --no-install-recommends \
gcc libpq-dev libjpeg-dev zlib1g-dev && \
rm -rf /var/lib/apt/lists/*
# 依赖(用 cache mount + BuildKit)
COPY requirements.txt .
RUN --mount=type=cache,target=/root/.cache/pip \
pip install --no-cache-dir --user \
--timeout 120 --retries 5 \
-i https://pypi.tuna.tsinghua.edu.cn/simple/ \
--trusted-host pypi.tuna.tsinghua.edu.cn \
-r requirements.txt
# 运行镜像
FROM python:3.12-slim
# 复制非 root 用户
COPY --from=builder /etc/passwd /etc/passwd
COPY --from=builder /etc/group /etc/group
# 运行时依赖(只 libpq5,**不装 curl**)
RUN --mount=type=cache,target=/var/cache/apt,sharing=locked \
--mount=type=cache,target=/var/lib/apt,sharing=locked \
apt-get update && \
apt-get install -y --no-install-recommends libpq5 && \
rm -rf /var/lib/apt/lists/*
WORKDIR /app
# 复制构建好的 Python 包
COPY --from=builder /root/.local /home/appuser/.local
COPY --chown=appuser:appuser . .
# 切非 root 用户
USER appuser
ENV PATH=/home/appuser/.local/bin:$PATH
ENV PYTHONUNBUFFERED=1
EXPOSE 8000
# 内置 healthcheck(不依赖 curl)
HEALTHCHECK --interval=30s --timeout=10s --start-period=40s --retries=3 \
CMD python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health').read()"
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]
```
**预期收益**:
- 镜像小 ~10 MB(删 curl)
- 安全(非 root)
- 加速 rebuild(BuildKit cache)
- 内置 healthcheck(无需依赖 compose)
---
## 📌 3. frontend Dockerfile 审计(agent + h5 同)
### 3.1 当前实现
```dockerfile
FROM node:20-slim AS builder
WORKDIR /app
COPY package.json package-lock.json* ./
RUN npm install
COPY . .
RUN npm run build
FROM nginx:1.27-alpine
COPY --from=builder /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
```
### 3.2 问题清单
| # | 问题 | 严重度 | 优化 |
|---|---|---|---|
| F-1 | ⚠️ **不用非 root**(nginx 默认 root) | 🟠 中 | 自定义 nginx.conf 改 user |
| F-2 | ⚠️ **没 nginx.conf** — 用默认 | 🟡 | 复制 custom nginx.conf |
| F-3 | ⚠️ **没 .dockerignore** | 🟡 | 加 |
| F-4 | ⚠️ **没 layer cache 优化** | 🟡 | BuildKit cache mount |
| F-5 | ⚠️ **不用 alpine node** | 🟡 | 改 `node:20-alpine` |
### 3.3 优化版
```dockerfile
# syntax=docker/dockerfile:1.7
FROM node:20-alpine AS builder
WORKDIR /app
# 装 pnpm(快 2-3 倍,磁盘省 50%)
RUN corepack enable && corepack prepare pnpm@9 --activate
# 依赖
COPY package.json pnpm-lock.yaml* ./
RUN --mount=type=cache,target=/root/.local/share/pnpm/store \
pnpm install --frozen-lockfile
# 源码 + 构建
COPY . .
RUN pnpm run build
# 运行镜像
FROM nginx:1.27-alpine
# 自定义 nginx.conf(非 root + 反代配置)
COPY nginx.conf /etc/nginx/nginx.conf
# 从 builder 复制 dist
COPY --from=builder --chown=nginx:nginx /app/dist /usr/share/nginx/html
# nginx alpine 默认是 nginx user
USER nginx
EXPOSE 80
HEALTHCHECK --interval=30s --timeout=3s --retries=3 \
CMD wget -q --spider http://localhost/ || exit 1
CMD ["nginx", "-g", "daemon off;"]
```
**预期收益**:
- 用 pnpm 代替 npm(快 2-3 倍)
- alpine node 镜像小 ~150 MB
- 自定义 nginx.conf + 非 root
- 内置 healthcheck
---
## 📌 4. .dockerignore 建议
**根目录** `.dockerignore`:
```
# Git
.git/
.gitignore
.gitattributes
.git-blame-ignore-revs
# 文档
docs/
*.md
!backend/README.md
# 测试

## 📌 5. 镜像大小优化(整体)
| 优化项 | 节省 | 风险 |
|---|---|---|
| backend 删 curl | 1 MB | 无 |
| 前端换 `node:20-alpine` | ~150 MB × 2 | 无 |
| 前端用 pnpm | ~50 MB × 2 | 无 |
| 加 .dockerignore | ~30% build 体积 | 无 |
| 跑 `docker system prune` | 100-500 MB | 无 |
| **总节省** | **~400 MB** | — |
---
## 📌 6. 安全加固
### 6.1 当前问题
| # | 问题 | 严重度 |
|---|---|---|
| S-1 | 全部容器跑 root | 🟠 中 |
| S-2 | 没 secret 扫描(防 docker build 时 COPY 进 secret) | 🟡 |
| S-3 | 没镜像漏洞扫描(Trivy) | 🟡 |
### 6.2 修复
1. **所有 Dockerfile 加 `USER` 指令**(已写优化版)
2. **加 Trivy 扫描到 CI**:
```yaml
# .gitea/workflows/security.yml
- name: Run Trivy vulnerability scanner
uses: aquasecurity/trivy-action@master
with:
image-ref: 'wecom-it-desk-backend:latest'
format: 'table'
exit-code: '1'
ignore-unfixed: true
```
3. **加 secret 扫描**:
- `.gitleaks.toml` 配 gitleaks
- pre-commit hook 跑 gitleaks
---
## 📌 7. 构建性能
| 优化 | 加速 | 实现 |
|---|---|---|

## 📌 3. Lockfile 治理
### 3.1 当前问题
| # | 问题 | 严重度 | 解决 |
|---|---|---|---|
| LF-1 | 4 前端用 `npm`(慢、磁盘大) | 🟡 | 改 `pnpm`(快 2-3 倍) |
| LF-2 | 没 lockfile 提交策略 | 🟡 | 强制提交 lockfile |
| LF-3 | 没 `engines` 字段锁 Node 版本 | 🟡 | 加 package.json `engines.node` |
| LF-4 | Python 没 `requirements.lock` | 🟠 | 用 `pip-tools` 生成 |
### 3.2 建议方案
#### Node 端
**`package.json` 统一加**:
```json
{
"engines": {
"node": ">=20.0.0 <21.0.0",
"pnpm": ">=9.0.0"
},
"packageManager": "pnpm@9.15.0"
}
```
**`.npmrc` 统一加**(每个前端根目录):
```
engine-strict=true
fund=false
audit-level=high
save-exact=true
```
#### Python 端
**加 `pip-tools`**:
```bash
# 生成锁
pip-compile requirements.in -o requirements.txt
# 同步环境
pip-sync requirements.txt
```
**`requirements.in`**(新增):
```
fastapi
uvicorn[standard]
python-multipart>=0.0.12
sqlalchemy
psycopg2-binary
asyncpg
alembic
redis>=5.0.7
pydantic>=2.7.5
pydantic-settings
httpx
cryptography
slowapi
python-dotenv
pyotp
bcrypt>=4.1.0
qrcode[pil]
pillow
```
---
## 📌 4. Renovate / Dependabot 配置
### 4.1 建议:启用 Gitea 内置依赖更新
**`.gitea/dependabot.yml`**(待启用):
```yaml
version: 2
updates:
# Python 后端
- package-ecosystem: "pip"
directory: "/backend"
schedule:
interval: "weekly"
open-pull-requests-limit: 5
labels:
- "dependencies"
- "python"
# 4 前端
- package-ecosystem: "npm"
directory: "/frontend-admin"
schedule:
interval: "weekly"
labels:
- "dependencies"
- "frontend"
# ... agent, h5, portal 同
# Docker 基础镜像
- package-ecosystem: "docker"
directory: "/backend"
schedule:
interval: "weekly"
labels:
- "dependencies"
- "docker"
```
### 4.2 短期手动
- 每周一次(周一)跑 `npm audit` + `pip-audit`
- 高危 / 严重 24 小时内修
- 中危 1 周内修
- 低危季度评估

### 2.4 前端错误码映射(axios 拦截器)
**新建 `frontend-admin/src/api/error-handler.ts`**(每个前端类似):
```typescript
import { ElMessage } from 'element-plus'
// 错误码 → 用户提示
const ERROR_MESSAGES: Record<number, string> = {
1001: '参数错误,请检查输入',
1002: '登录已过期,请重新登录',
1003: '资源不存在',
1004: '无权限访问',
1005: '服务器错误,请稍后重试',
1006: '操作过快,请稍候再试',
2001: '请先登录',
2002: '登录已过期',
2003: '身份验证失败',
2004: '请输入动态码',
2005: '动态码错误',
2006: '密码错误',
4001: '会话不存在',
4002: '会话已结束',
5001: '坐席不存在',
5002: '坐席离线',
5003: '坐席已满载',
9999: '未知错误',
}
export function handleError(code: number, message: string, traceId?: string) {
const userMsg = ERROR_MESSAGES[code] || message || '操作失败'
// 特殊处理
if ([1002, 2001, 2002, 2003].includes(code)) {
// 跳登录
localStorage.removeItem('token')
window.location.href = '/login'
}
ElMessage.error(userMsg)
// 开发环境显示 trace_id
if (import.meta.env.DEV && traceId) {
console.error(`[TraceID: ${traceId}] Code: ${code}, Message: ${message}`)
}
}
```

## 📌 3. 日志结构化
### 3.1 现状
```python
# backend/app/main.py
logging.basicConfig(
level=logging.INFO,
format="[%(asctime)s] [%(levelname)s] [%(name)s] %(message)s",
)
```
**问题**:
- 🟡 文本格式,不易查询/聚合
- 🟡 无 trace_id
- 🟡 无 request/response 记录
- 🟡 无结构化字段(用户/会话/操作)
### 3.2 改进版
**新建 `backend/app/utils/logging_config.py`**:
```python
import json
import logging
import sys
import time
from contextvars import ContextVar
from typing import Any, Dict, Optional
# 请求上下文
request_id_var: ContextVar[Optional[str]] = ContextVar('request_id', default=None)
user_id_var: ContextVar[Optional[str]] = ContextVar('user_id', default=None)
class JSONFormatter(logging.Formatter):
"""JSON 格式化器 - 适合 ELK / Loki / CloudWatch 解析"""
def format(self, record: logging.LogRecord) -> str:
log_data = {
"timestamp": self.formatTime(record),
"level": record.levelname,
"logger": record.name,
"message": record.getMessage(),
}
# 上下文
if request_id_var.get():
log_data["request_id"] = request_id_var.get()
if user_id_var.get():
log_data["user_id"] = user_id_var.get()
# 额外字段
if hasattr(record, "extra_data"):
log_data.update(record.extra_data)
# 异常
if record.exc_info:
log_data["exception"] = self.formatException(record.exc_info)
return json.dumps(log_data, ensure_ascii=False)
def setup_logging(level: str = "INFO", json_format: bool = True):
"""配置日志"""
root = logging.getLogger()
root.setLevel(level)
# 清除已有 handler
for handler in root.handlers[:]:
root.removeHandler(handler)
handler = logging.StreamHandler(sys.stdout)
if json_format:
handler.setFormatter(JSONFormatter())
else:
handler.setFormatter(logging.Formatter(
"[%(asctime)s] [%(levelname)s] [%(name)s] %(message)s"
))
root.addHandler(handler)
# 业务日志辅助函数
def log_business(
event: str,
*,
user_id: str = None,
conversation_id: str = None,
agent_id: str = None,
**kwargs
):
"""记录业务日志(结构化)"""
extra_data = {
"event": event,
"user_id": user_id,
"conversation_id": conversation_id,
"agent_id": agent_id,
**kwargs,
}
logger.info(f"business_event: {event}", extra={"extra_data": extra_data})
def log_security(
event: str,
*,
user_id: str = None,
ip: str = None,
**kwargs
):
"""记录安全日志(单独级别,便于审计)"""
extra_data = {
"event": event,
"category": "security",
"user_id": user_id,
"ip": ip,
**kwargs,
}
logger.warning(f"security_event: {event}", extra={"extra_data": extra_data})
```
**中间件 - 注入 request_id**:
```python
# backend/app/main.py
from app.utils.logging_config import setup_logging, request_id_var, user_id_var
import uuid
@app.middleware("http")
async def request_id_middleware(request: Request, call_next):
# 拿/创 trace_id
trace_id = request.headers.get("X-Request-ID") or str(uuid.uuid4())
request_id_var.set(trace_id)
# 记录请求开始
start = time.time()
logger.info(
f"request_start: {request.method} {request.url.path}",
extra={"extra_data": {
"method": request.method,
"path": request.url.path,
"client": request.client.host if request.client else "?",
}}
)
response = await call_next(request)
# 记录请求结束
duration = time.time() - start
logger.info(
f"request_end: {response.status_code} in {duration:.3f}s",
extra={"extra_data": {
"method": request.method,
"path": request.url.path,
"status": response.status_code,
"duration_ms": int(duration * 1000),
}}
)
response.headers["X-Request-ID"] = trace_id
return response
```
### 3.3 日志聚合方案
| 方案 | 适用 | 接入成本 |
|---|---|---|
| **stdout + Docker logs** | 小规模 / 排障 | 🟢 0 |
| **Loki + Promtail** | 中规模 / 查日志 | 🟡 中 |
| **ELK (Elasticsearch + Logstash + Kibana)** | 大规模 / 全文搜索 | 🟠 高 |
| **CloudWatch / 阿里云 SLS** | 公有云 | 🟡 看云 |
**短期**: 走 stdout,Docker 收集到 `/var/log/wecom-it-desk/*.log`,脚本 + grep 查
**中期**: Loki + Grafana(本地 NAS 部署)
**长期**: ELK / 云原生日志
