PayPal快速结账服务器端,身份验证失败

dim*_*pak 1 authentication curl codeigniter paypal express-checkout

我到处搜索了很多,但没有找到我的问题的答案。

我不能让它工作。我的 PayPal 按钮使用快速结账服务器端 Rest,但我测试了客户端,这很容易,而且可以工作。

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_URLEXECUTE_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",

                "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($ch2, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch2, CURLOPT_POSTFIELDS, $data);

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

因此,当我单击 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 https://w…://www.paypalobjects.com/api/checkout.js:3076:13pass to payment? at )", errtype: "[object Error]"

未捕获的错误:没有传递给付款的值

而且,当我将控制器输入 url 以查看数组时,它会显示:

Array ( [name] => AUTHENTICATION_FAILURE [message] => 由于身份验证凭据无效或授权标头丢失,身份验证失败。[links] => Array ( [0] => Array ( [href] => https://developer.paypal.com/docs/api/overview/#error[rel] =>信息链接 ) ) )

好的,我在处理 1 周后解决了我的问题,我终于找到了解决方案,现在它运行得非常好!

AUTHENTICATION_FAILURE [message] => 由于身份验证凭据无效或授权标头丢失,身份验证失败。

这是因为我发送了两个单独的 HTTPHEADERS 而不是一个,结果是相互覆盖。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"));

之后我仍然有问题:

ppxo_no_token_passed_to_payment

ppxo_unhandled_error {stack: "错误:没有传递给付款的值?

未捕获的错误:没有传递给付款的值

为了解决这个问题,我只是像这样在没有 json_decode 的情况下回显结果:

$result = curl_exec($ch2);

echo $result;

curl_close($ch2);

现在一切正常。

executeurl 控制器很简单,如果有人想让我发布它告诉我。

我希望我能帮助有类似问题的人。
