[ ] 生成搜索参数失败

Error message

[%s] 生成搜索参数失败: %w

What it means

encryptPayload failed while building the encrypted search request body from the searchPayload and the fetched apiConfig. The plugin cannot construct a valid request, so the search is aborted before any HTTP call is made and the underlying crypto/packing error is wrapped with this message.

Solutions

1. Inspect the wrapped error from encryptPayload for the root cause (missing field, serialization, crypto)
2. Re-fetch the config via fetchConfig and confirm URLVersion/UserID are populated and current
3. Ensure the encryption implementation matches the server version tied to config.URLVersion
4. Update searchPayload fields to match the expected API schema

Example fix

// before
cfg, _ := p.fetchConfig(ctx, client) // stale cached config
// after
cfg, err := p.fetchConfig(ctx, client)
if err != nil { return nil, err } // always search with a freshly validated config

if config.URLVersion == "" || config.UserID == "" {
    return errors.New("cannot encrypt payload: config missing URLVersion/UserID")
}

items, err := p.search(ctx, client, cfg, kw)
if err != nil {
    if strings.Contains(err.Error(), "生成搜索参数失败") {
        log.Printf("payload encryption failed; re-fetching config: %v", err)
        cfg, err = p.fetchConfig(ctx, client)
        if err == nil {
            items, err = p.search(ctx, client, cfg, kw)
        }
    }
    return err
}

When it happens

Trigger: encryptPayload(payload, config) returns an error inside search, e.g. because config fields (URLVersion/UserID/Start/End) are unsuitable for key derivation or the payload cannot be serialized/encrypted.

Common situations: A config field is empty or malformed despite validation (schema drift), the encryption scheme/keys no longer match the server version indicated by URLVersion, or the payload struct changed and breaks serialization.
