调用网站支付时报错HttpFoundationFactory not found

$order = [
            'out_trade_no' => time(),
            'total_amount' => '1',
            'subject' => 'test subject - 测试',
        ];

        $html = Pay::alipay()->web($order);

遇到这个问题是因为Guzzle的使用是需要依赖这个包的，但是我们没有，解决方法非常直接：

composer require symfony/psr-http-message-bridge
