未获取到数据！

Error message

未获取到数据！

What it means

Generic Error ('No data retrieved!') thrown when the Miyoushe image-ranking API returns HTTP 200 but response.data.data.list is missing. The upstream call succeeded but the expected list array is absent — typically an empty result for that ranking/cate combination or an upstream envelope change.

Solutions

Try the default rankingType=daily and cateType=illustration to confirm the route works for that game.
Retry after a few minutes in case of a transient empty response.
Verify cateType is valid for the game/forum combination (see route description table).
If persistent, report an envelope change to maintainers.

Example fix

// before
// /mihoyo/bbs/img-ranking/ys/forumType=tongren&cateType=qute&rankingType=daily

// after
// /mihoyo/bbs/img-ranking/ys/forumType=tongren&cateType=illustration&rankingType=daily

Defensive patterns

Strategy: retry

Validate before calling

// Validate combination shape before calling API
const { cate_id } = getCateInfo(game, forum_type, cate_type);
if (!cate_id) throw new Error('Invalid cateType for this game/forum');

Type guard

function hasRankingList(res: any): boolean {
    return Array.isArray(res?.data?.data?.list);
}

Try / catch

try {
    const list = response?.data?.data?.list;
    if (!list) throw new Error('No ranking data yet — retry later');
} catch (e) { /* retry or return allowEmpty */ }

Prevention

Retry weekly/monthly rankings that may be temporarily empty.
Default to daily/illustration which is most populated.
Return allowEmpty feeds instead of hard-failing for resilience.

When it happens

Trigger: got(getImagePostList) resolves, but response.data.data.list is falsy. Happens when cate_id/ranking_type combination yields no posts, the game's ranking is temporarily empty, or the API returned an error envelope with HTTP 200.

Common situations: Asking for a weekly/monthly ranking that hasn't been populated yet; an invalid cate_type for that forum; upstream transient error; API envelope changed.
