Question

我正在尝试将Paypal快速结账集成与PayPal REST API集成。

JS文件如下所示：

paypal.Button.render({
    env: 'sandbox', // sandbox | production
    commit: true,
    payment: function() {
        var CREATE_URL = 'createpayment';

        return paypal.request.get(CREATE_URL)
            .then(function(res) {
                return res.paymentID;
            });
    },

    onAuthorize: function(data, actions) {
        var EXECUTE_URL = 'executepayment';
        var data = {
            paymentID: data.paymentID,
            payerID: data.payerID
        };
        return paypal.request.post(EXECUTE_URL, data)
            .then(function (res) {
                window.alert('Payment Complete!');
            });
    }

}, '#paypal-button-container');

现在我无法弄清楚CREATE_URL和EXECUTE_URL url的php文件应该是什么。我已经阅读了很多他们的文档。我明白在php中我应该首先请求获取令牌，然后我应该创建创建付款请求并在执行付款后卷曲reuqest。但我没有运气。

我也不明白应该如何将付款值传递给CREATE_URL php文件。

几天前，我在这里找到了一些关于我的问题的一个很好的答案和所有例子，但是大约两天我找不到它。

更新：我还需要将输入金额从付款请求传递到php文件。我不能使用return paypal.request.get（CREATE_URL，data）请求。

请有人帮帮我。

谢谢。

分享服务器PHP代码的一些示例。

CREATE_URL中的PHP代码：

    <?php
    $curl = curl_init();
     
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp');
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query(array(
        'USER' => 'xxxxx',
        'PWD' => 'xxxxx',
        'SIGNATURE' => 'xxxxx',
     
        'METHOD' => 'SetExpressCheckout',
        'VERSION' => '108',
        'LOCALECODE' => 'en_US',
     
        'PAYMENTREQUEST_0_AMT' => 100,
        'PAYMENTREQUEST_0_CURRENCYCODE' => 'USD',
        'PAYMENTREQUEST_0_PAYMENTACTION' => 'Sale',
        'PAYMENTREQUEST_0_ITEMAMT' => 100,
     
        'L_PAYMENTREQUEST_0_NAME0' => 'test name',
        'L_PAYMENTREQUEST_0_DESC0' => 'test desc',
        'L_PAYMENTREQUEST_0_QTY0' => 1,
        'L_PAYMENTREQUEST_0_AMT0' => 100,
     
        'CANCELURL' => 'http://localhost/cancel.html',
        'RETURNURL' => 'http://localhost/success.html'
    )));
     
    $response =    curl_exec($curl);
     
    curl_close($curl);
     
    $nvp = array();
     
    if (preg_match_all('/(?<name>[^\=]+)\=(?<value>[^&]+)&?/', $response, $matches)) {
        foreach ($matches['name'] as $offset => $name) {
            $nvp[$name] = urldecode($matches['value'][$offset]);
        }
    }
    if (isset($nvp['ACK']) && $nvp['ACK'] == 'Success') {
        echo $nvp['TOKEN'];
    } else {
        //failed
    } 

    ?>

EXECUTE_URL中的PHP代码：

<?php
$curl = curl_init();
 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp');
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query(array(
    'USER' => 'xxxxx',
    'PWD' => 'xxxxx',
    'SIGNATURE' => 'xxxxx',
 
    'METHOD' => 'DoExpressCheckoutPayment',
    'VERSION' => '108',
    'LOCALECODE' => 'en_US',
 
    'TOKEN' => $_POST['TOKEN'],
    'PayerID' => $_POST['PAYERID'],
 
    'PAYMENTREQUEST_0_AMT' => 100,
    'PAYMENTREQUEST_0_CURRENCYCODE' => 'USD',
    'PAYMENTREQUEST_0_PAYMENTACTION' => 'Sale',
    'PAYMENTREQUEST_0_ITEMAMT' => 100,
     
    'L_PAYMENTREQUEST_0_NAME0' => 'test name',
    'L_PAYMENTREQUEST_0_DESC0' => 'test desc',
    'L_PAYMENTREQUEST_0_QTY0' => 1,
    'L_PAYMENTREQUEST_0_AMT0' => 100,
)));
 
$response =    curl_exec($curl);
 
curl_close($curl);
 
$nvp = array();
 
if (preg_match_all('/(?<name>[^\=]+)\=(?<value>[^&]+)&?/', $response, $matches)) {
    foreach ($matches['name'] as $offset => $name) {
        $nvp[$name] = urldecode($matches['value'][$offset]);
    }
}
 
print_r($nvp);
