- groups 新增 i18n JSONB 列(迁移 242):语言代码 -> {name, description},只存译文;
name/description 原列语义不变,仍用于唯一性校验、搜索与各类日志
- 用户侧接口由后端按请求语言输出:取 Accept-Language 中权重最高的一项,先按完整
语言代码、再按主语言匹配;该语言有译文的字段换成译文,否则保持原字段,且不再带出
译文表。覆盖密钥、可用分组、订阅(含进度与汇总)、兑换、使用记录、可用渠道、
模型广场、套餐列表
- 管理端接口一律返回原字段;分组管理接口额外带 i18n 供编辑
- 创建/编辑分组:名称、描述的标题行右侧新增语言下拉,同一个输入框在默认内容与各语言
版本之间切换;语种跟随前端 availableLocales
- 管理端写入:创建/更新接受 i18n(更新时缺省不修改,传入则整体替换),校验语言代码
形态与名称长度并丢弃空译文;简易模式同样放行;复制分组只带走描述译文
- 切换界面语言后整页刷新,让已加载的数据换成新语言;模型广场响应加
Vary: Accept-Language
- 网关路径,以及只带 group_name 字符串的统计、错误记录出口不做本地化
