无效的排序类型

Error message

无效的排序类型

What it means

Thrown by the asianfanfics tag route when the URL :type parameter is missing or not one of the allowed sort codes L, N, O, C, OS (each mapped to a Chinese label). It is an input-validation guard before the ofetch to asianfanfics.com, so the request never fires for an invalid sort type.

Solutions

1. Use one of the documented sort codes: L (recently updated), N (recently published), O (earliest published), C (completed), OS (short stories).
2. If you believe a new code should be supported, add it to both the includes array and the labels map and open a PR.

Example fix

// before
if (!type || !['L', 'N', 'O', 'C', 'OS'].includes(type)) {
    throw new Error('无效的排序类型');
}

// after: derive a typed constant so the allow-list and labels stay in sync
const SORT_LABELS = { L: '最近更新', N: '最近发布', O: '最早发布', C: '已完成', OS: '短篇' } as const;
type SortType = keyof typeof SORT_LABELS;
const VALID_SORTS = new Set(Object.keys(SORT_LABELS));
if (!VALID_SORTS.has(type)) {
    throw new InvalidParameterError(`Invalid sort type: ${type}. Allowed: ${[...VALID_SORTS].join(', ')}`);
}

const VALID_SORTS = new Set(['L', 'N', 'O', 'C', 'OS']);
const type = String(ctx.req.param('type') ?? '').toUpperCase();
if (!VALID_SORTS.has(type)) {
    throw new InvalidParameterError(`Invalid sort type. Allowed: ${[...VALID_SORTS].join(', ')}`);
}

const SORT_LABELS = { L: '最近更新', N: '最近发布', O: '最早发布', C: '已完成', OS: '短篇' } as const;
type SortType = keyof typeof SORT_LABELS;
function isSortType(v: string): v is SortType {
    return Object.prototype.hasOwnProperty.call(SORT_LABELS, v);
}

When it happens

Trigger: Calling /asianfanfics/tag/:tag/:type with a type value outside {L,N,O,C,OS}, or omitting type entirely so ctx.req.param('type') is undefined.

Common situations: User mistypes the sort code; route example copied with a wrong placeholder; upstream adds a new sort option that the route has not whitelisted.
