CI_Merchant没有显示任何内容

Question

对于在线支付，我正在尝试使用ci_merchant。 根据http://ci-merchant.org/ ，我做了一个CodeIgniter项目。 但是该功能仅显示空白页。

我的功能如下：

 function transaction(){
    $this->load->library('merchant');
    $this->merchant->load('paypal_express');
    $settings = $this->merchant->default_settings();

    $settings = array(
        'username' => 'AAAAAAAAAAA',
        'password' => '111111',
        'signature' => 'AAAAAAAAAAAARCpSSRl31AoJ0SIOUHEnDbhhEgANdZeAmMTkU',
        'test_mode' => true
    );
    $this->merchant->initialize($settings);

        $params = array(
            'amount' => 1.00,
            'currency' => 'USD',
            'return_url' => 'http://localhost/tcm/account/transaction_return',
            'cancel_url' => 'http://localhost/tcm/account/transaction_cancel'
        );
        //'return_url' => 'https://www.example.com/checkout/payment_return/123',
        //'cancel_url' => 'https://www.example.com/checkout');
        $response = $this->merchant->purchase($params);

        if ($response->success()){
            echo "Successfully complete transaction.";
        }
        else{
            $message = $response->message();
            echo('Error processing payment: ' . $message);
            exit;
        } 
}

我的代码或过程的问题在哪里？ 等待肯定的回应。

我认为您错过了以下代码片段中的$this->部分：

if ($response->success()){
            echo "Successfully complete transaction.";
        }
        else{
            $message = $response->message();
            echo('Error processing payment: ' . $message);
            exit;
        } 

尝试使用：

if ($response->$this->success()){
            echo "Successfully complete transaction.";
        }
        else{
            $message = $response->$this->message();
            echo('Error processing payment: ' . $message);
            exit;
        }
