PayPal 快速结帐服务器端，身份验证失败

Question

我到处搜索但没有找到问题的答案。

我做不到。我的 PayPal 按钮使用快速结帐服务器端 Rest，但我测试了客户端，它很简单，而且有效。

我正在使用 CodeIgniter，所以这是我的代码。

这是我的视图文件夹中的 javascript 代码。 CREATE_URL 和 EXECUTE_URL 转到控制器。

paypal.Button.render({

        env: 'sandbox', // sandbox | production

        // Show the buyer a 'Pay Now' button in the checkout flow
        commit: true,

        // payment() is called when the button is clicked
        payment: function() {

            // Set up a url on your server to create the payment
            var CREATE_URL = '/projects/createurl';

            // Make a call to your server to set up the payment
            return paypal.request.post(CREATE_URL)
                .then(function(res) {
                    return res.paymentID;
                });
        },

        // onAuthorize() is called when the buyer approves the payment
        onAuthorize: function(data, actions) {

            // Set up a url on your server to execute the payment
            var EXECUTE_URL = '/projects/executeurl';

            // Set up the data you need to pass to your server
            var data = {
                paymentID: data.paymentID,
                payerID: data.payerID
            };

            // Make a call to your server to execute the payment
            return paypal.request.post(EXECUTE_URL, data)
                .then(function (res) {
                    window.alert('Payment Complete!');
                });
        }

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

这里是CREATE_URL控制器

public function createurl() {

            $ch = curl_init();
    $clientId = "something";
    $secret = "something";

    curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSLVERSION , 6); 
    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);

    if(empty($result))die("Error: No response.");
    else
    {
        $json = json_decode($result, TRUE);
    }



    curl_close($ch); 


    $ch2 = curl_init();
    $token = $json['access_token'];
    $data = '{
            "transactions": [{
            "amount": {
                "currency":"EUR",
                "total":"12"
            },
            "description":"creating a payment"
            }],
            "payer": {
                "payment_method":"paypal"
            },
            "intent":"sale",
            "redirect_urls": {
                "cancel_url":"https://mysite.gr/projects/project/10",
                "return_url":"https://mysite.gr/projects/project/10"
            }
       }'; 


    curl_setopt($ch2, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment");
    curl_setopt($ch2, CURLOPT_VERBOSE, 1);
    curl_setopt($ch2, CURLOPT_HEADER, 0);
    curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch2, CURLOPT_HTTPHEADER , "Content-Type: application/json");
    curl_setopt($ch2, CURLOPT_HTTPHEADER , "Authorization: Bearer ".$token);
    curl_setopt($ch2, CURLOPT_POST, 1);
    curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch2, CURLOPT_POSTFIELDS, $data);

    $result = curl_exec($ch2);
    $json = json_decode($result, TRUE); 
    print_r($json);
    curl_close($ch2);
}

所以当我点击 PayPal 按钮时 - 它失败了。来自控制台的日志：

ppxo_no_token_passed_to_payment

ppxo_unhandled_error {stack: "Error: No value passed to payment↵ at https://w…://www.paypalobjects.com/api/checkout.js:3076:13)", errtype: "[object Error]"

Uncaught Error: No value passed to payment

而且当我将控制器输入 url 以查看数组时，它会这样说：

Array ( [name] => AUTHENTICATION_FAILURE [message] => Authentication failed due to invalid authentication credentials or a missing Authorization header. [links] => Array ( [0] => Array ( [href] => https://developer.paypal.com/docs/api/overview/#error [rel] => information_link ) ) )

Answer 1

好的，经过 1 周的努力，我解决了我的问题，我终于找到了解决方案，现在效果很好！

AUTHENTICATION_FAILURE [message] => Authentication failed due to invalid authentication credentials or a missing Authorization header.

这是因为我发送的是两个单独的 HTTPHEADERS 而不是一个，结果是互相覆盖。所以正确的做法是在 HTTPHEADER 的第三个参数中传递一个数组，如下所示：

curl_setopt($ch2, CURLOPT_HTTPHEADER , array("Content-Type: application/json", "Authorization: Bearer myaccesstokenishere"));

之后我仍然遇到问题：

ppxo_no_token_passed_to_payment

ppxo_unhandled_error {stack: "Error: No value passed to payment↵

Uncaught Error: No value passed to payment

为了解决这个问题，我只是回显结果而不是 json_decode，就像这样：

$result = curl_exec($ch2);

echo $result;

curl_close($ch2);

现在一切正常。

executeurl 控制器很简单，如果有人想让我post告诉我。

我希望我帮助了遇到类似问题的人。
