Paypal学习 3 -- 接受信用卡直接付款 （DoDirectPayment）

    我们的页面可以提供用户直接填写信用卡付款的功能。具体步骤如下：

     1） 在我们sandbox business账户下面添加一张信用卡，这张信用卡的信息可以是真实的，由于是在sandbox下，我们做测试所pay的都不会真正从信用卡中划掉，所以可以放心。具体路径：

            sandbox --> My Account --> Profile --> Financial Information --> credit cards --> add a credit card

     2） 找到此business账号的个人信息： 包括username  password  signature, 具体路径

           登录到paypal developer， --> Dashboard --> Sandbox --> Accounts --> Profile --> API credencials

     3) 拿到个人信息后就可以编写代码了，

           

<?php

// Set sandbox (test mode) to true/false.
$sandbox = TRUE;

// Set PayPal API version and credentials.
$api_version = '85.0';
$api_endpoint = $sandbox ? 'https://api-3t.sandbox.paypal.com/nvp' : 'https://api-3t.paypal.com/nvp';
$api_username = $sandbox ? 'your username' : 'LIVE_USERNAME_GOES_HERE';
$api_password = $sandbox ? 'your password' : 'LIVE_PASSWORD_GOES_HERE';
$api_signature = $sandbox ? 'your signature' : 'LIVE_SIGNATURE_GOES_HERE';

// Store request params in an array
$request_params = array
(
'METHOD' => 'DoDirectPayment',

'PWD' => $api_password,

);

// Loop through $request_params array to generate the NVP string.
$nvp_string = '';
foreach($request_params as $var=>$val)
{
$nvp_string .= '&'.$var.'='.urlencode($val);
}

// Send NVP string to PayPal and store response
$curl = curl_init();
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_URL, $api_endpoint);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $nvp_string);

$result = curl_exec($curl);
curl_close($curl);
$nvp_response_array = parse_str($result);
print_r($nvp_response_array);

?>

     4) request_parameter里面包含了信用卡的信息。
