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。但是该函数只显示空白页。

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?等待肯定回复

我想你错过了下面代码片段中的$this->部分:

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

试试:

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