[ ] 读取响应失败

Error message

[%s] 读取响应失败: %w

What it means

CldiPlugin.searchPage wraps io.ReadAll(resp.Body) failures with the plugin name. The response arrived but its body could not be read to completion — usually the connection was reset mid-transfer or the body was truncated (unexpected EOF). It is a one-shot read here: no retry is attempted after this point.

Solutions

1. Retry the search; transient resets often succeed on a second attempt.
2. Check for intermediary proxies/LBs with short idle timeouts and raise them.
3. Increase client timeouts and use a bounded reader to avoid oversized bodies.
4. Verify network stability between client and the site.

results, err := plugin.Search(ctx, keyword)
if err != nil {
    if strings.Contains(err.Error(), "读取响应失败") {
        // transient: retry once after short backoff, then degrade to cached results
    }
}

When it happens

Trigger: io.ReadAll(resp.Body) returns err in searchPage, typically when the server or an intermediary closes the connection before the full HTML body is delivered.

Common situations: Large search-result pages over unstable connections, load balancer idle timeouts cutting the transfer, proxy interference, or server-side crashes mid-response.
