后端 FastAPI 六层结构(api/services/repositories/models/schemas/core), 统一响应信封、全局异常、日志脱敏;6 张表经 Alembic 迁移建库,SQL 留存 db/migration;登录鉴权含图形验证码(Redis GETDEL 防重放)、JWT、登录限流、 登出黑名单(TTL=令牌剩余有效期)、登录日志。 前端 Vue3 + TS + Element Plus 骨架,含登录页、路由守卫、请求封装与 Vite 代理。 工程配置:uv 锁定 Python 3.12、ruff 检查与格式化、editorconfig、gitattributes。 测试 184 项(单元 155 / 集成 29)全绿,浏览器端到端 8 项通过。 Co-Authored-By: Claude Code <noreply@anthropic.com>

"""浏览器端端到端验证:登录 + 图形验证码。
|
||
|
||
验证的是**只有真实浏览器才能暴露**的问题:
|
||
|
||
- 路由守卫是否真的拦住了未登录访问
|
||
- 验证码图片能否经 Vite 代理正常渲染(跨前后端的完整链路)
|
||
- 登录失败后验证码是否自动刷新 —— 后端用 GETDEL 消费了验证码,
|
||
前端不刷新的话第二次提交必然失败,而这个问题在人工测试时极易被忽略
|
||
- 刷新页面能否用 /me 恢复会话
|
||
- 登出后令牌是否立即失效
|
||
|
||
**运行前置**(缺一不可)::
|
||
|
||
docker compose -f docker/docker-compose.dev.yml up -d # MySQL + Redis
|
||
cd backend && uv run uvicorn app.main:app --port 8000 # 后端
|
||
cd frontend && pnpm dev # 前端
|
||
|
||
运行::
|
||
|
||
cd frontend && python e2e/login_flow.py
