Error message

re.Message

What it means

Thrown by GetRandomVideoOfUp when the Bilibili search-by-up-id API returns a non-zero code. Any failure listing an UP主's videos (private/banned account, API rejection, risk control) is surfaced directly to the caller as BiliBusinessException(re.Message).

Solutions

1. Check re.Message to identify the specific Bilibili error code.
2. Verify the UP id (mid) exists and the account still has public videos.
3. Recompute the video total (GetVideoCountOfUp) before picking a random page so pn stays in range.
4. Refresh the Bilibili cookie if the message indicates authentication failure.

Example fix

// before: random page from possibly stale total
pn = new Random().Next(1, total + 1),
// after: refresh total and clamp
var total = await GetVideoCountOfUp(upId, ck);
if (total <= 0) return null;
pn = new Random().Next(1, total + 1)

// ensure the UP has videos and total is fresh before picking a random page
var total = await videoDomainService.GetVideoCountOfUp(upId, ck);
if (total <= 0)
    return; // skip this UP, no videos to interact with

bool CanInteractWithUp(long upId, int total) => upId > 0 && total > 0;

try
{
    var video = await videoDomainService.GetRandomVideoOfUp(upId, total, ck);
}
catch (BiliBusinessException ex)
{
    logger.LogWarning("获取UP主({upId})视频失败，跳过：{msg}", upId, ex.Message);
}

When it happens

Trigger: apiApi.SearchVideosByUpId responds with re.Code != 0 — the UP id doesn't exist or the account is closed/hidden, the pn page number (random) exceeds available pages and Bilibili rejects it, cookie invalid, or risk-control code returned.

Common situations: Target UP主 deleted/privated all videos so the search API errors; the random page number computed from a stale total exceeds the current page count; cookie expired; Bilibili search API changed behavior.
