获取热门评论失败

Error message

获取热门评论失败

What it means

Thrown by Kuwo's getHotComment when the recommended/hot comment API at http://ncomment.kuwo.cn/com.s (type=get_rec_comment) returns a non-200 HTTP status or body.code is not '200'. Structurally identical to error 40 but targets hot/rec comments. Uses the same plain-http endpoint and the same loose-equality guard, so it shares all transport and contract fragility.

Solutions

1. Distinguish 'no hot comments' from 'API error' by logging body.code and statusCode; if body.code indicates empty results, return an empty list instead of throwing.
2. Verify songmid validity before calling getHotComment.
3. Retry with backoff for transient failures.
4. Test the endpoint URL directly with curl using the Dalvik User-Agent to check if Kuwo changed the contract.

Example fix

// before
if (statusCode != 200 || body.code != '200') throw new Error('获取热门评论失败')

// after
if (statusCode != 200 || !body || body.code != '200') {
  console.warn('kw getHotComment failed', { statusCode, code: body?.code })
  if (body?.code && body.code !== '200') return { source: 'kw', comments: [], total: 0, page, limit, maxPage: 1 }
  throw new Error('获取热门评论失败')
}

function canFetchHotComments(songmid) {
  return typeof songmid === 'string' && songmid.length > 0
}

function isKwHotCommentResponse(body) {
  return body != null && typeof body === 'object' && typeof body.code !== 'undefined'
}

try {
  const result = await kwComment.getHotComment({ songmid }, page, limit)
} catch (err) {
  if (err.message === '获取热门评论失败') {
    console.warn('Kuwo hot comments unavailable for', songmid)
    return { source: 'kw', comments: [], total: 0, page, limit, maxPage: 1 }
  }
  throw err
}

When it happens

Trigger: Calling getHotComment({ songmid }, page, limit) where the song has no hot/recommended comments (Kuwo returns a non-200 body.code). Network interference with ncomment.kuwo.cn. A cancelled or rate-limited request. The same songmid that works for regular comments may return no hot comments.

Common situations: Songs with low popularity have no recommended comments, so Kuwo returns a non-200 code. ISP-level HTTP interception. The app's proxy configuration routes Kuwo traffic through a tunnel that strips headers.
