在我的网站中，我希望实施自适应贝宝付款方式。是否可以使用curl实现。任何人都可以提供自适应支付的php代码

【解决方案1】：

这是 curl 调用 paypal 的代码

对于自适应支付，您首先需要使用您的“clientId”和“密钥”生成访问令牌。然后使用该访问令牌，您可以调用 Paypal 自适应支付 API。

我已经给出了生成访问令牌的示例。然后从 paykey 获取交易详情（您可以根据自己的要求更改通话）。

//Get access token from client Id

                $ch = curl_init();
                $clientId = PAYPAL_CLIENT_ID;
                $secret = PAYPAL_CLIENT_SECRET;
                curl_setopt($ch, CURLOPT_URL, 'https://api.sandbox.paypal.com/v1/oauth2/token');// Change it to "https://api.paypal.com/v1/oauth2/token" for live
                curl_setopt($ch, CURLOPT_HEADER, false);
                curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                curl_setopt($ch, CURLOPT_POST, true);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($ch, CURLOPT_USERPWD, $clientId . ":" . $secret);
                curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
                $result = curl_exec($ch);
                $accessToken = null;
                if (empty($result))
                    return 'Access Token could not generated';
                else {
                    $json = json_decode($result);
                    $accessToken = $json->access_token;
                }
                curl_close($ch);



                /**
                 * Get payment transaction details from
                 * - AccessToken
                 * - PayKey
                 */
                $curl = curl_init('https://api.sandbox.paypal.com/v1/payments/payment/' . $input['payKey']);
                curl_setopt($curl, CURLOPT_POST, false);
                curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
                curl_setopt($curl, CURLOPT_HEADER, false);
                curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
                curl_setopt($curl, CURLOPT_HTTPHEADER, array(
                    'Authorization: Bearer ' . $accessToken,
                    'Accept: application/json',
                    'Content-Type: application/json'
                ));
                $response = curl_exec($curl);
                $result = json_decode($response);

您可以参考 paypal curl 调用的示例 https://github.com/paypal/rest-api-curlsamples/blob/master/execute_all_calls.php

这真的很有帮助！但是 Github 上的那些例子被删除了。也许你知道我在哪里可以再次找到它们？

能否使用curl函数实现自适应支付。
