歌手不存在

Error message

歌手不存在

What it means

Kugou singer.getInfo in kg/singer.js:10 guards `if (id == 0) throw '歌手不存在'` (singer does not exist). KG returns singerid 0 for tracks whose artist isn't registered with Kugou; getInfo refuses to fetch a meaningless id=0 singer profile rather than returning junk. Called when the UI requests a singer's detail/avatar/description.

Solutions

1. Check for a falsy/zero singer id before calling getInfo and hide the singer-detail section in the UI.
2. Fall back to a generic 'unknown artist' state instead of invoking the API.
3. Handle the throw at the call site and show 'artist information unavailable'.
4. Filter out id==0 songs from singer-navigation affordances.

Example fix

// before
  getInfo(id) {
    if (id == 0) throw new Error('歌手不存在')
    ...
  }

// after - guard at the call site, no throw
const info = singerId && singerId != 0
  ? await kgSinger.getInfo(singerId)
  : null
if (!info) renderUnknownArtist()

const isResolvableSinger = (id) => id != null && Number(id) !== 0
if (!isResolvableSinger(singerId)) {
  // hide singer detail section, do not call getInfo
  renderUnknownArtist()
  return
}

const isResolvableSingerId = (id) =>
  (typeof id === 'number' && id !== 0) || (typeof id === 'string' && id !== '' && id !== '0')

let info = null
try {
  if (singerId != 0) info = await kgSinger.getInfo(singerId)
} catch (e) {
  info = null // render 'artist unavailable'
}

When it happens

Trigger: getInfo is invoked with a singer id of exactly 0 — typically derived from a song whose `singerid` KG populated with 0 because the artist is unregistered or unknown.

Common situations: An obscure or unregistered artist; KG data-quality issues; a song object whose singer field was synthesized without a real id; id parsing producing 0 from a missing field.
