README

constant 包 (/constant)

该目录仅用于放置全局可复用的常量定义，不包含任何业务逻辑或依赖关系。

当前文件

文件 说明
azure.go 定义与 Azure 相关的全局常量，如 AzureNoRemoveDotTime（控制删除 . 的截止时间）。
cache_key.go 缓存键格式字符串及 Token 相关字段常量，统一缓存命名规则。
channel_setting.go Channel 级别的设置键，如 proxy、force_format 等。
context_key.go 定义 ContextKey 类型以及在整个项目中使用的上下文键常量（请求时间、Token/Channel/User 相关信息等）。
env.go 环境配置相关的全局变量，在启动阶段根据配置文件或环境变量注入。
finish_reason.go OpenAI/GPT 请求返回的 finish_reason 字符串常量集合。
midjourney.go Midjourney 相关错误码及动作(Action)常量与模型到动作的映射表。
setup.go 标识项目是否已完成初始化安装 (Setup 布尔值)。
task.go 各种任务(Task)平台、动作常量及模型与动作映射表，如 Suno、Midjourney 等。
user_setting.go 用户设置相关键常量以及通知类型(Email/Webhook)等。

使用约定

  1. constant 包只能被其他包引用（import），禁止在此包中引用项目内的其他自定义包。如确有需要，仅允许引用 Go 标准库。
  2. 不允许在此目录内编写任何与业务流程、数据库操作、第三方服务调用等相关的逻辑代码。
  3. 新增类型时，请保持命名语义清晰，并在本 README 的 当前文件 表格中补充说明，确保团队成员能够快速了解其用途。

⚠️ 违反以上约定将导致包之间产生不必要的耦合，影响代码可维护性与可测试性。请在提交代码前自行检查。
