[ ] 人机验证未通过

Error message

[%s] 人机验证未通过: %w

What it means

This error is returned by MiosouPlugin.ensureGate after 3 attempts of completeAnubisChallenge all fail; the last attempt's error is wrapped. ensureGate is invoked by searchImpl before searching (and again when a gate response is detected), so this error means the Anubis proof-of-work anti-bot challenge could not be solved or submitted.

Solutions

1. Read the wrapped lastErr to see which stage failed (request, parse, solve, or submit)
2. Increase gateTimeout if solveAnubisChallenge runs out of time due to high difficulty
3. Update parseAnubisChallenge and the pass request against the site's current Anubis version
4. Test from a different IP/network — flagged IPs get endless challenges

Example fix

// before
ctx, cancel := context.WithTimeout(context.Background(), gateTimeout)
err := p.completeAnubisChallenge(ctx)
// after (only if timeouts are the wrapped cause)
gateTimeout = 60 * time.Second // raised from previous value
ctx, cancel := context.WithTimeout(context.Background(), gateTimeout)

// Go: check challenge fetchability before full ensureGate
resp, err := http.Get(baseURL + "/")
if err != nil || resp.StatusCode != http.StatusOK {
    // cannot even reach challenge page; skip and retry later
}

func isGateFailure(err error) bool {
    return err != nil && strings.Contains(err.Error(), "人机验证未通过")
}

if err := p.ensureGate(); err != nil {
    var to net.Error
    if errors.As(err, &to) && to.Timeout() {
        gateTimeout *= 2 // difficulty may have increased; give PoW more time
    }
    return nil, fmt.Errorf("gate setup failed, will retry later: %w", err)
}

When it happens

Trigger: ensureGate loops 3 times calling completeAnubisChallenge(ctx) with gateTimeout context; every attempt returns an error (challenge request failed, page fetch failed, challenge not found with non-200, PoW solve failed, or pass submission rejected), producing "人机验证未通过: <lastErr>".

Common situations: Anubis difficulty raised so PoW cannot finish within gateTimeout; site updated the challenge page markup so parseAnubisChallenge returns found=false with non-200; pass-endpoint response rejected; the host is on a blocklist so every challenge is invalidated.
