[ ] 获取分享链接失败

Error message

[%s] 获取分享链接失败: %w

What it means

searchImpl resolves share links for each search hit concurrently; if every resolution attempt failed (resolvedCount == 0) and at least one error was captured, it wraps the first error (firstErr) with 获取分享链接失败. This means none of the results could get a usable share link, so no results are returned.

Solutions

Inspect the wrapped firstErr (%w) for the root cause — network error vs HTTP status vs parse failure.
Test connectivity to the Yingso upstream from the host (curl the endpoint).
If authentication/cookies are involved, refresh them.
Add retry with backoff for transient network failures.

Defensive patterns

Strategy: fallback

Try / catch

results, err := search(keyword)
if err != nil {
    if strings.Contains(err.Error(), "获取分享链接失败") {
        log.Printf("all share-link resolutions failed: %v", err)
        return cachedOrEmptyResults
    }
    return err
}

Prevention

Add retries with exponential backoff for link resolution.
Check host network/proxy configuration before deploying.
Refresh upstream credentials/sessions regularly.
Monitor upstream availability and degrade gracefully to cached results.

When it happens

Trigger: All concurrent requests to resolve share links for the found items failed — network errors, upstream timeouts, anti-bot blocks, or invalid item metadata (e.g. missing share IDs) — so resolvedCount stayed 0.

Common situations: Yingso upstream is down or blocking the client IP; expired session/cookies cause every link-resolution call to fail; network outage or proxy misconfiguration on the host running the plugin.
