嗨，我注意到示例中有 3 个示例请求。
授权购买捕获
我不断收到 Security Header 无效的错误消息，所以我尝试编写自己的代码进行测试。
我想做的就是通过快速结账开始购买，而不发送信用卡详细信息。
到目前为止我的代码：
<?php
echo 'testing the omnipay';
require __DIR__.'/../Vendor/autoload.php';
use Omnipay\Common\GatewayFactory;
$gateway = GatewayFactory::create('PayPal_Express');
$gateway->setUsername('some_username');
$gateway->setPassword('some_password');
$gateway->setSignature('some_signature');
$gateway->setTestMode(true);
echo 'start';
$params = array(
'amount' => '1.99',
'currency' => 'SGD',
'description' => 'test purchase',
'transactionId' => '123',
'transactionReference' => '123ref',
'returnUrl' => 'http://localhost:8000/gateways/PayPal_Express/completeAuthorize',
'cancelUrl' => 'http://localhost:8000/gateways/PayPal_Express/authorize',
);
echo 'end';
$response = $gateway->capture($params);
echo 'after capture';
echo '<pre> ';
print_r ($response);
echo '</pre> ';
我的输出是：
