问题

用户反馈上传 20MB 视频提示文件过大。

根因

  1. OSS_DIRECT_UPLOAD_MAX_MB 默认值 800，且 .env.production 中的 MAX_UPLOAD_SIZE_MB=2000 因变量名不匹配被 pydantic extra="ignore" 静默忽略
  2. nginx client_max_body_size 为 800m

修复

P0

  • config.py: OSS_DIRECT_UPLOAD_MAX_MB 默认值 800→2000
  • config.py: 添加 AliasChoices 支持 MAX_UPLOAD_SIZE_MB 环境变量

P1

  • infra/nginx/xiaoxia-saas.conf: client_max_body_size 800m→2g（3处）
  • infra/docker/nginx-production.conf: client_max_body_size 800m→2g

验证

  • ✅ 默认值=2000
  • ✅ MAX_UPLOAD_SIZE_MB 可被正确读取
  • ✅ OSS_DIRECT_UPLOAD_MAX_MB 向后兼容

部署后需操作

  1. nginx reload
  2. 确认 .env.production 中 MAX_UPLOAD_SIZE_MB=2000
  3. 检查 OSS Bucket 策略

代码审计审查报告 — PR #117（后端）

审查结论：⚠️ 有条件通过（需确认 PR 去重）

Head SHA: b5e27a5e | 变更： 4 文件 +52/-16

✅ 通过项

  1. config.py 修改正确

    • OSS_DIRECT_UPLOAD_MAX_MB 默认值 800→2000 ✓
    • AliasChoices 兼容 MAX_UPLOAD_SIZE_MB 环境变量 ✓
    • pydantic 导入完整（AliasChoices, Field）✓

  2. Nginx 配置修改正确

    • xiaoxia-saas.conf：3 处 client_max_body_size 800m→2g ✓
    • nginx-production.conf：1 处 800m→2g ✓

⚠️ P2：前后端大小限制不一致

层级 限制值 字节数
前端 2GB 2,147,483,648
后端 2000MB 2,097,152,000

差异约 50MB。2000MB < 文件大小 ≤ 2GB 的文件会被前端放行但被后端 413 拒绝。

建议： 后端改为 2048（即 2GB）或前端改为 2000 * 1024 * 1024，保持一致。

⚠️ 流程问题：PR #117 和 PR #118 是同一个 commit

两个 PR 的 Head SHA 完全相同（b5e27a5e），变更文件完全一致。应只保留一个 PR 合并，另一个关闭。

P1: prepareDirectUpload and completeDirectUpload now require project_id,
uploadAssetDirect calls getOrCreateDefaultProject() to obtain it automatically.
P2: MAX_FILE_SIZE changed from 2*1024^3 to 2048*1024*1024 to align with
backend OSS_DIRECT_UPLOAD_MAX_MB=2000.
