// services/api/src/api-exception.ts —— 携带契约错误码的业务异常(Task 7 遗留项①)。
|
|||
|
|
// 状态码表(过滤器内 STATUS_TO_ERROR_CODE)只能表达"一个 HTTP 状态 = 一个错误码",
|
|||
|
|
// 无法表达同状态多错误码的契约空间(如 401 既可能是 AUTH_TOKEN_EXPIRED 也可能是
|
|||
|
|
// AUTH_INVALID_CREDENTIALS,409 既可能是 MEMBER_CONFLICT 也可能是
|
|||
|
|
// UPLOAD_SESSION_CONFLICT)。业务代码抛 ApiException 精确指定 ErrorCode;
|
|||
|
|
// 过滤器优先识别它,状态码表仅作普通 HttpException 的兜底映射。
