Error message

发表评论失败: ${error.response?.data?.error?.message || error.message}

What it means

The catch-all of postComment (tiktok.service.ts:806-809). The POST to /v2/comment/post/ failed and is re-wrapped as BadRequestException('发表评论失败: ...') with TikTok's error message. Posting comments requires the comment.list scope plus app approval, and the target video must allow comments.

Solutions

Read the '发表TikTok评论失败:' log for error.response?.data.error.code/message.
Confirm the app has been granted TikTok's comment post API access (restricted scope requiring application).
Verify the target video has comments enabled and belongs to the authorized user.
Sanitize/shorten the comment text and avoid duplicate/repetitive posts that trigger anti-spam.
Refresh the access token if the error indicates auth failure.

Example fix

null

Defensive patterns

Strategy: validation

Validate before calling

if (!commentDto?.videoId || !commentDto?.text?.trim()) {
  throw new Error('videoId and non-empty text are required');
}
if (commentDto.text.length > 150) {
  throw new Error('comment text exceeds TikTok length limit');
}

Type guard

function isValidCommentDto(d: unknown): d is { videoId: string; text: string } {
  const o = d as any;
  return typeof o?.videoId === 'string' && o.videoId.length > 0
    && typeof o?.text === 'string' && o.text.trim().length > 0;
}

Try / catch

try {
  await tiktokService.postComment(token, dto);
} catch (e) {
  if (/permission|not approved|scope/i.test(e.message)) {
    // app lacks comment-post access: apply via TikTok developer portal
  } else if (/spam|frequent/i.test(e.message)) {
    // throttle: queue the comment and slow down
  } else throw e;
}

Prevention

Apply early for TikTok comment-post API access — it's a restricted permission.
Deduplicate comment text and rate-limit posts per account to avoid anti-spam.
Check the target video allows comments before posting.
Keep tokens fresh and re-consent when TikTok adds new required scopes.

When it happens

Trigger: POST /v2/comment/post/ returns 4xx/5xx: comment posting not approved for the app, comments disabled on the target video, text containing blocked content or exceeding length limits, invalid/expired token, or video_id not commentable.

Common situations: Apps lacking TikTok's comment API approval (it's restricted access); bots flagged by anti-spam on repeated identical comments; posting to private or comment-disabled videos; region restrictions on the comment endpoints.
