发布到端点以在购买前获取重定向网址

Question

我正在尝试为名为creditguard的本地网关创建一个自定义的omnipay驱动程序.对于此网关,您需要将数据发布到端点并返回付款表单的重定向URL.

我的问题是你如何在购买前发布并获得回复？

        return $data;

    public function sendData($data)

        return $this->response = new PurchaseResponse($this, $data);
    }

    public function getEndpoint()
    {
        return $this->getTestMode() ? $this->testEndpoint : $this->liveEndpoint;
    }
}

PurchaseResponse.php

    class PurchaseResponse extends AbstractResponse implements RedirectResponseInterface
{
    public function isSuccessful()
    {
        return false;
    }

    public function isRedirect()
    {
        return true;
    }

    public function getRedirectUrl()
    {
        // return $this->getRequest()->getEndpoint().'?'.http_build_query($this->data);
        return $this->getRequest()->data['mpiHostedPageUrl'];
        // return isset($this->data['mpiHostedPageUrl']) ? $this->data['mpiHostedPageUrl'] : null;
    }

    public function getRedirectMethod()
    {
        return 'GET';
    }

    public function getRedirectData()
    {
        return [];

    }
}

不知道如何获得响应的mpiHostedPageUrl所以我可以重定向到正确的URL.

Answer 1

HATEOAS（超媒体作为应用程序状态引擎）是一种组织 REST 应用程序响应的方法。在 HATEOAS 世界中，响应 JSON 可能包含客户端可能需要的所有 URL。例如，在 github API 中，响应包含用于访问存储库、用户、拉取请求的 URL...

因此，我建议您使用第一个 POST 请求调用网关，然后根据 JSON 响应，调用提供的表示重定向的 URL。
