Omnipay Paypal Express Checkout Error: Security header is not valid

Question

每当使用 setTestMode() 方法时，都会弹出错误 "Security header is not valid"。

但是如果我删除 setTestMode() 并只保留 setUsername()、setPassword() 和 setSignature() 方法，它会通过并直接重定向到 PayPal (Live Paypal)。

所以 AFAIK 问题应该在于我如何使用 setTestMode 而不是关于不正确的 API 信用，因为大多数 "Security header is not valid" 错误都是关于。

我目前正在使用 Laravel 5.8 和 Omnipay/PayPal 使用 PayPal Express Checkout

这是使用过的文件

Paypal.php

public function gateway()
{
    $gateway = Omnipay::create('PayPal_Express');

    $gateway->setUsername(config('services.paypal.username'));
    $gateway->setPassword(config('services.paypal.password'));
    $gateway->setSignature(config('services.paypal.signature'));
    $gateway->setTestMode(config('services.paypal.sandbox'));
    // $gateway->setTestMode(true);

    return $gateway;
}

public function purchase(array $parameters)
{
    $response = $this->gateway()
        ->purchase($parameters)
        ->send();

    return $response;
}

PaypalController.php

public function checkout($order_id)
{
    $order = Order::findOrFail(decrypt($order_id));

    $paypal = new PayPal;

    $response = $paypal->purchase([
        'amount' => $paypal->formatAmount($order->amount),
        'transactionId' => $order->transaction_id,
        'currency' => 'PHP',
        'cancelUrl' => $paypal->getCancelUrl($order),
        'returnUrl' => $paypal->getReturnUrl($order),
        'notifyUrl' => $paypal->getNotifyUrl($order),
    ]);

    if ($response->isRedirect()) {
        $response->redirect();
    }

    return redirect()->back()->with([
            'message' => $response->getMessage(),                
    ]);
}

这是$response

的内容

刚刚创建了一个新的 Sandbox 企业帐户并使用了那个人的 NVP API Creds，然后就成功了！旧帐号的问题可能是我编辑的电子邮件，因为这是新旧帐户之间唯一的区别。

Answer 1

实时环境和 test/sandbox 环境是完全独立的，因此需要单独的凭据。

对于 PayPal 沙盒（测试模式），您需要来自 sandbox PayPal 企业帐户的 API 用户名、密码和签名，通过 https://www.paypal.com/signin?intent=developer&returnUri=https%3A%2F%2Fdeveloper.paypal.com%2Fdeveloper%2Faccounts%2F

10002 "Security Header is not Valid" 总是表示您的凭据无效，即 Username/Password/Signature 有问题或者您在沙盒模式下使用实时凭据，反之亦然
