【中文标题】无法让 Paypal 在上下文中 checkout.js v4 与 REST API 一起使用【英文标题】：Trouble getting Paypal in-context checkout.js v4 work with REST API 【发布时间】：2017-08-17 21:09:53 【问题描述】：我是 Paypal 和 php 的新手，所以也许我做错了（或没做）， 我正在尝试让 Paypal 上下文结帐 v4 使用服务器端工作，以便能够在付款完成后进行操作。我遵循了 Paypal 指南（https://github.com/paypal/paypal-checkout/blob/master/docs/button.md 和 https://github.com/paypal/paypal-checkout/blob/master/docs/paypal-rest-api.md）并进行了大量研究，但目前没有一个有用。
我在调用创建付款后遇到问题，Paypal 窗口不显示 Paypal 登录信息，而是向我显示消息 "返回商家 目前，我们无法处理您的请求。请返回并尝试其他选项。”
这是我服务器端的代码：
class ExpressCheckout
private $request = null;
function createPayment()
$token = $this->getConnectionToken();
$this->request = curl_init();
$paypalmode = (PPL_MODE=='sandbox') ? '.sandbox' : '';
$data = $this->getDataFromSession();
$url = 'https://api'.$paypalmode.'.paypal.com/v1/payments/payment';
$this->setDefaultRequest();
curl_setopt($this->request, CURLOPT_HTTPHEADER, array("Authorization: Bearer $token",
'Content-Type: application/json'));
curl_setopt($this->request, CURLOPT_POSTFIELDS, $data);
curl_setopt($this->request, CURLOPT_URL, $url);
$response = $this->sendHttp($url);
return '"paymentID":"'.$response->id.'"';
function executePayment()
$token = $this->getConnectionToken();
$entryData = json_decode(file_get_contents('php://input'), true);
$paymentId = $entryData["paymentID"];
$payerId = $entryData["payerID"];
$this->request = curl_init();
$paypalmode = (PPL_MODE=='sandbox') ? '.sandbox' : '';
$data = '"payer_id":"'.$payerID.'"';
$url = 'https://api'.$paypalmode.'.paypal.com/v1/payments/payment/'.$paymentId.'/execute';
$this->setDefaultRequest();
curl_setopt($this->request, CURLOPT_HTTPHEADER, array("Authorization: Bearer $token",
'Content-Type: application/json'));
curl_setopt($this->request, CURLOPT_POSTFIELDS, $data);
curl_setopt($this->request, CURLOPT_URL, $url);
$response = $this->sendHttp($url);
return $response;
function getConnectionToken()
$this->request = curl_init();
$userName = PPL_REST_API_CLIENT_ID;
$password = PPL_REST_API_SECRET;
$paypalmode = (PPL_MODE=='sandbox') ? '.sandbox' : '';
$url = 'https://api'.$paypalmode.'.paypal.com/v1/oauth2/token';
$data = 'grant_type=client_credentials';
$this->setDefaultRequest();
curl_setopt($this->request, CURLOPT_USERPWD, "$userName:$password");
curl_setopt($this->request, CURLOPT_POSTFIELDS, $data);
$response = $this->sendHttp($url);
return $response->access_token;
private function setDefaultRequest()
curl_setopt($this->request, CURLOPT_VERBOSE, 1);
curl_setopt($this->request, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($this->request, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($this->request, CURLOPT_TIMEOUT, 45);
curl_setopt($this->request, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->request, CURLOPT_POST, 1);
private function sendHttp($url)
curl_setopt($this->request, CURLOPT_URL, $url);
$responseJson = json_decode(curl_exec($this->request));
curl_close ($this->request);
return $responseJson;
我的客户的代码是：

【问题讨论】：
【参考方案1】：如果您正在调用沙盒来设置付款，您可能需要在paypal.Button.render() 中传递env: 'sandbox'。
