关键词不能为空

Error message

关键词不能为空

What it means

Thrown by the asianfanfics text-search route when the :keyword path parameter is empty or whitespace-only. The handler trims the keyword before building the search URL, so a blank keyword is rejected before the ofetch is made.

Solutions

1. Supply a non-empty keyword, e.g. /asianfanfics/text-search/fluff.
2. If empty-search behavior is desired, change the guard to return an empty feed instead of throwing.

Example fix

// before
if (keyword.trim() === '') {
    throw new Error('关键词不能为空');
}

// after
if (!keyword?.trim()) {
    throw new InvalidParameterError('Keyword must not be empty');
}

const keyword = String(ctx.req.param('keyword') ?? '').trim();
if (!keyword) {
    throw new InvalidParameterError('Keyword must not be empty');
}

function isNonEmptyKeyword(v: unknown): v is string {
    return typeof v === 'string' && v.trim().length > 0;
}

When it happens

Trigger: Requesting /asianfanfics/text-search/ with no keyword, or with a keyword that is only spaces (URL-decoded to whitespace).

Common situations: Malformed RSS reader URL; user clears the keyword field; trailing slash route matching yields an empty param.
