获取热门评论失败

Error message

获取热门评论失败

What it means

Thrown by QQ Music's getHotComment when the newer musicu.fcg endpoint at https://u.y.qq.com/cgi-bin/musicu.fcg returns non-200, body.code !== 0, OR body.req.code !== 0. This is the only error with a double-nested code check (both the outer envelope and the inner req object must report success). Uses HTTPS and a POST with a JSON body (module: music.globalComment.CommentRead, method: GetHotCommentList). Reads body.req.data.CommentList.

Solutions

1. Log body.code, body.req.code, and statusCode separately to identify which layer failed.
2. Update the module/method strings to match the current QQ Music web client by inspecting y.qq.com network traffic.
3. Update the User-Agent string periodically to match current Chrome/Edge versions.
4. Retry with backoff for transient failures.
5. Fall back to the legacy fcg_global_comment endpoint if musicu.fcg is blocked.

Example fix

// before
if (statusCode != 200 || body.code !== 0 || body.req.code !== 0) throw new Error('获取热门评论失败')

// after
if (statusCode != 200 || !body || body.code !== 0 || !body.req || body.req.code !== 0) {
  console.warn('tx getHotComment failed', { statusCode, code: body?.code, reqCode: body?.req?.code })
  throw new Error('获取热门评论失败')
}

function hasTxSongId(mInfo) {
  return mInfo != null && (!!mInfo.songId || !!mInfo.songmid)
}

function isTxHotCommentResponse(body) {
  return body != null && typeof body === 'object' && body.code === 0 && body.req != null && body.req.code === 0 && body.req.data != null
}

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

When it happens

Trigger: Calling getHotComment(mInfo, page, limit) where the outer envelope succeeds (body.code === 0) but the inner request fails (body.req.code !== 0), or vice versa. Tencent changes the module/method path. The song has no hot comments. Rate-limiting or anti-bot detection rejects the request at either layer.

Common situations: Tencent's musicu.fcg is an anti-scraping endpoint that frequently changes its module/method contract. The inner req.code may be non-zero for geo-restricted or removed songs. The Chrome/Edge User-Agent string may be flagged and blocked by Tencent's bot detection over time.
