CakePHP 2.x 组件，用于与 PayPal WPP 交互

用法

在您的 APP 中加载插件，并通过以下 bootstrap.php 配置文件启用它

	CakePlugin::load('PaypalWPP');

通过以下方式打开 Config/paypal.php 文件来配置您的账户

	$config = [
		'paypal' => [
			'username'  => 'username_api1.domain.com',
			'password'  => 'THGSWS658IKUN79S',
			'signature' => 'AFYn4irhcVyzOOiJkc.H2zPIuztlArzO7mr5uXMO6DLICAE85JF.H5PPp',
			'endpoint'  => 'https://api-3t.paypal.com/nvp',
			'version'   => '53.0',
		],
	];

将组件加载到您选择的控制器中。

	public $components = [
		'PaypalWPP.PaypalWPP',
	];

接下来对您的数据进行 urlencode，并通过方法和 nvp 将其发送到组件。对于使用 DoDirectPayment（https://developer.paypal.com/webapps/developer/docs/classic/api/merchant/DoDirectPayment_API_Operation_NVP/）进行支付，以下示例将有效

    /**
     * Add Method.
     */
    public function add()
    {
		if ($this->request->is('post') || $this->request->is('put')) {
			$firstName        = urlencode($this->request->data['Sale']['first_name']);
			$lastName         = urlencode($this->request->data['Sale']['last_name']);
			$creditCardType   = $this->request->data['Sale']['card_type'];
			$creditCardNumber = $this->request->data['Sale']['card_number'];
			$expDateMonth     = $this->request->data['Sale']['exp']['month'];
			$padDateMonth     = str_pad($expDateMonth, 2, '0', STR_PAD_LEFT);
			$expDateYear      = $this->request->data['Sale']['exp']['year'];
			$cvv2Number       = $this->request->data['Sale']['cvv2'];
			$amount           = $this->request->data['Sale']['amount'];
			$nvp              = '&PAYMENTACTION=Sale';
			$nvp             .= '&AMT=' . $amount;
			$nvp             .= '&CREDITCARDTYPE=' . $creditCardType;
			$nvp             .= '&ACCT=' . $creditCardNumber;
			$nvp             .= '&CVV2=' . $cvv2Number;
			$nvp             .= '&EXPDATE=' . $padDateMonth.$expDateYear;
			$nvp             .= '&FIRSTNAME=' . $firstName;
			$nvp             .= '&LASTNAME=' . $lastName;
			$nvp             .= '&COUNTRYCODE=US&CURRENCYCODE=USD';

			$response = $this->PaypalWPP->wpp_hash('DoDirectPayment', $nvp);
			if ($response['ACK'] == 'Success') {
				$this->Session->setFlash('Payment Successful');
			} else {
				$this->Session->setFlash('Payment Failed');
			}
			debug($response);
		}
