获取 Anubis 验证题目失败

Error message

获取 Anubis 验证题目失败: %w

What it means

completeAnubisChallenge sends a GET to the Anubis-protected site root to fetch a proof-of-work challenge page. This error wraps the http.Client.Do failure for that initial request (miosou.go:162). ensureGate retries up to 3 times before surfacing it as 人机验证未通过.

Solutions

1. Check basic connectivity to the site (curl -v the baseURL) and DNS/proxy settings.
2. Verify the HTTP client's proxy/timeout configuration (http.Transport, http.ProxyFromEnvironment).
3. Rely on ensureGate's 3 retries; increase gateTimeout if the network is slow.
4. If Anubis blocks the client, verify setPageHeaders sends a browser-like User-Agent.

Example fix

// before
resp, err := p.client.Do(req)
if err != nil {
    return fmt.Errorf("获取 Anubis 验证题目失败: %w", err)
}
// after
resp, err := p.client.Do(req)
if err != nil {
    if errors.Is(err, context.DeadlineExceeded) {
        return fmt.Errorf("获取 Anubis 验证题目超时: %w", err)
    }
    return fmt.Errorf("获取 Anubis 验证题目失败: %w", err)
}

// check reachability before calling
resp, err := http.Head(baseURL + "/")
if err != nil {
    return fmt.Errorf("site unreachable: %w", err)
}
resp.Body.Close()

err := p.ensureGate()
if err != nil {
    var netErr net.Error
    if errors.As(err, &netErr) && netErr.Timeout() {
        // back off and retry later
    }
    return err
}

When it happens

Trigger: p.client.Do on GET baseURL+/ fails: DNS failure, connection refused/reset, TLS error, request context (gateTimeout) expired, or proxy unreachable.

Common situations: No internet/VPN, corporate proxy or firewall blocking the host, the miosou site being down or Anubis blocking non-browser clients, or gateTimeout being too short on slow networks.
