[ ] 搜索请求失败

Error message

[%s] 搜索请求失败: %w

What it means

jutoushe searchImpl wraps the error returned by doRequestWithRetry — meaning the HTTP request to the site failed after all internal retries (connection errors, TLS errors, timeouts). The wrapped lastErr explains the network-level cause.

Solutions

1. Inspect the wrapped error for the root cause (dial tcp / timeout / x509)
2. Test connectivity to the site from the host (curl baseURL)
3. Increase the 30s context timeout if on slow networks
4. Check whether the site is blocking the User-Agent/IP and adjust headers or use a proxy

Example fix

// before
resp, err := p.doRequestWithRetry(req, client)
if err != nil { return nil, fmt.Errorf("[%s] 搜索请求失败: %w", p.Name(), err) }
// after
resp, err := p.doRequestWithRetry(req, client)
if err != nil {
    var ne net.Error
    if errors.As(err, &ne) && ne.Timeout() {
        return nil, fmt.Errorf("[%s] search timed out: %w", p.Name(), err)
    }
    return nil, fmt.Errorf("[%s] 搜索请求失败: %w", p.Name(), err)
}

conn, err := net.DialTimeout("tcp", "www.jutoushe.cc:443", 5*time.Second)
if err != nil { return fmt.Errorf("site unreachable before search: %w", err) }
conn.Close()

results, err := plugin.Search(keyword)
if err != nil {
    var ne net.Error
    if errors.As(err, &ne) && ne.Timeout() {
        return retryLater(err) // back off and retry later
    }
    return err
}

When it happens

Trigger: p.doRequestWithRetry(req, client) exhausts its retries: server unreachable, DNS failure, TLS handshake error, or context timeout (30s) expires mid-flight.

Common situations: Target site blocked or down; no internet/DNS in the deployment environment; site rate-limiting the scraper's IP; 30s context too short on slow networks.

Understand the failure class

Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
