获取回复评论失败

Error message

获取回复评论失败

What it means

Kugou reply-thread comment fetcher in kg/comment.js:60. Hits comment.service.kugou.com /index.php?r=commentsv2/getReplyWithLike with an Android COMMENT UA. Requires HTTP 200 and body.err_code === 0; otherwise throws '获取回复评论失败' (failed to fetch reply comments). Notably, songmid is remapped (audioId.split('_')[0]) when its length is 32 to work around a KG id-storage change.

Solutions

  1. Verify the 32-char songmid remap (audioId.split('_')[0]) still matches KG's current childrenid format.
  2. Confirm the replyId is still valid (re-fetch the parent comment if stale).
  3. Treat a missing-thread err_code as an empty list instead of throwing.
  4. Retry with backoff and degrade to 'no replies' in the UI.

Example fix

// before
    if (statusCode != 200 || body.err_code !== 0) throw new Error('获取回复评论失败')

// after - include diagnostics
    if (statusCode != 200 || body.err_code !== 0) {
      throw new Error(`获取回复评论失败 (status=${statusCode}, err_code=${body?.err_code}, tid=${replyId})`)
    }
Defensive patterns

Strategy: fallback

Validate before calling

// validate replyId and remapped songmid before calling
const validReplyTarget = ({ songmid, audioId }, replyId) =>
  typeof replyId === 'string' && replyId !== '' &&
  (songmid == null || typeof songmid === 'string') &&
  (audioId == null || typeof audioId === 'string')

Type guard

const isReplyThreadRef = (ref) =>
  ref != null && typeof ref === 'object' &&
  (typeof ref.songmid === 'string' || ref.songmid == null) &&
  typeof ref.replyId !== 'undefined'

Try / catch

async function loadKgReplies(ref, replyId, page, limit) {
  try {
    return await kgComment.getReplyComment(ref, replyId, page, limit)
  } catch (e) {
    return { source: 'kg', comments: [], error: e.message } // show 'no replies' in UI
  }
}

Prevention

When it happens

Trigger: Non-200 or err_code != 0; the 32-char songmid remap produces an invalid childrenid; the replyId points at a deleted/hidden thread; the hardcoded Android COMMENT UA is blocked; signature drift on the `code` param.

Common situations: The reply thread was removed by Kugou; a stale replyId cached client-side; the songmid remap logic mismatches KG's current id format; rate-limiting.
