PayPalLaravel 8集成使用srmklive错误

Question

我想将PayPal集成到我的Laravel网站中，但我遇到了以下错误：

传递给Symfony\Component\HttpFoundation\RedirectResponse:：\uu construct（）的参数1必须是在C:\xampp\htdocs\Delta\vendor\laravel\framework\src\illighte\Routing\Redirector中调用的字符串类型（给定null）。php在线233

控制器文件

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Srmklive\PayPal\Services\ExpressCheckout;

class PayPalController extends Controller {
    public function __construct() {
        $this->provider = new ExpressCheckout();
    }

    public function payment() {
        $data = [];
        $data['items'] = [
            [
                'name' => 'codechief.org',
                'price' => 100,
                'desc'  => 'Description goes herem',
                'qty' => 1
            ]
        ];

        $data['invoice_id'] = 1;
        $data['invoice_description'] = "Order #{$data['invoice_id']} Invoice";
        $data['return_url'] = route('payment.success');
        $data['cancel_url'] = route('payment.cancel');
        $data['total'] = 100;
        $provider = new ExpressCheckout;
        $response = $provider->setExpressCheckout($data);
        $response = $provider->setExpressCheckout($data, true);
        return redirect()->away($response['paypal_link']);
    }

请给我一个解决方案！

Answer 1

实际上，您的问题是，$响应['paypal\u link']没有返回链接。替换行：

return redirect()->away($response['paypal_link']);

代码如下：

if($response['paypal_link'] == null){
   // custom redirection
   return redirect()->back()->with(['error'=>'paypal link no set'])
}
return redirect()->away($response['paypal_link']);
