获取评论失败
Error message
获取评论失败
What it means
Thrown by Kuwo's getComment when the regular comment API at http://ncomment.kuwo.cn/com.s (type=get_comment) returns a non-200 HTTP status or a body whose code field is not the string '200'. The loose equality (!=) means a numeric 200 also passes, so only truly non-200 codes or missing/mismatched body.code trigger it. This is the SDK's single guard: it cannot distinguish a network failure from an API rejection or an empty/HTML body.

Solutions
- Log statusCode and body before the throw to identify whether the failure is transport-level (non-200) or API-level (body.code mismatch).
- Verify the songmid is a valid Kuwo music ID before calling getComment.
- If the app runs in an HTTPS-enforcing environment, switch the URL from http:// to https:// and test.
- Retry once with backoff since transient rate-limiting from Kuwo is common.
- Check whether Kuwo changed the body.code contract by hitting the URL directly in a browser or curl.
Example fix
// before
const { body, statusCode } = await _requestObj.promise
if (statusCode != 200 || body.code != '200') throw new Error('获取评论失败')
// after
const { body, statusCode } = await _requestObj.promise
if (statusCode != 200 || !body || body.code != '200') {
console.warn('kw getComment failed', { statusCode, code: body?.code })
throw new Error('获取评论失败')
} Defensive patterns
Strategy: try-catch
Validate before calling
function isValidKwCommentParams(songmid, page, limit) {
return typeof songmid === 'string' && songmid.length > 0 && page >= 1 && limit >= 1 && limit <= 100
} Type guard
function isKwCommentResponse(body) {
return body != null && typeof body === 'object' && typeof body.code !== 'undefined'
} Try / catch
try {
const result = await kwComment.getComment({ songmid }, page, limit)
} catch (err) {
if (err.message === '获取评论失败') {
console.warn('Kuwo comments unavailable for', songmid)
return { source: 'kw', comments: [], total: 0, page, limit, maxPage: 1 }
}
throw err
} Prevention
- Validate songmid is a non-empty string before calling getComment.
- Distinguish transport failures (non-200) from API failures (body.code) by logging both.
- Return an empty result set rather than propagating the error when the song simply has no comments.
- Be aware the URL uses plain HTTP — test in your network environment.
When it happens
Trigger: Calling getComment({ songmid }, page, limit) where songmid is invalid or the Kuwo comment endpoint is rate-limited/blocked. The HTTP scheme is plain http (not https), so corporate proxies, HTTPS-only environments, or DNS hijacking can return non-200 or HTML that fails JSON parsing (body becomes a string, body.code is undefined). Also fires when Kuwo changes its response contract (body.code format).
Common situations: The song has no comments on Kuwo (body.code may be a non-200 error code). ISP or GFW interference with the Kuwo domain. A stale songmid from cache. The app running behind a proxy that upgrades http to https and breaks the endpoint.
