我将 PayPal 移动支付集成到我的应用程序中。那没什么大不了的。我设置了当客户从我的应用程序购买时，详细信息会发布到我的服务器。也没什么大不了的。但是，对于我的生活，我无法获得 PayPal 交易详情。我在 LogCat 中看到了详细信息，但无论我尝试什么，我都无法抓住任何东西。我知道它必须简单，但我一直坐在这里，每一次尝试都是徒劳的。我可以得到一些细节，但不是全部。任何帮助，将不胜感激。在我完全掌握他们的 SDK 之前，我还没有对 PayPal 开发人员网站上发布的代码做任何戏剧性的事情，但它就在这里。

protected void onActivityResult (int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
            if (confirm != null) {
                try {
                    Log.i("paymentExample", confirm.toJSONObject().toString(4));

                    // TODO: send 'confirm' to your server for verification.
                    // see https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/
                    // for more details.








//String PAYMENT_CONFIRMATION = confirm.toJSONObject().getJSONObject("pay_key").toString();
                    //  Log.d("PAYMENT CONFIRMATION KEY::", PAYMENT_CONFIRMATION)   ;




               new Update_CloseLines().execute();


                } catch (JSONException e) {
                    Log.e("paymentExample", "an extremely unlikely failure occurred: ", e);
                }
            }
        }
        else if (resultCode == Activity.RESULT_CANCELED) {
            Log.i("paymentExample", "The user canceled.");
        }
        else if (resultCode == PaymentActivity.RESULT_PAYMENT_INVALID) {
            Log.i("paymentExample", "An invalid payment was submitted. Please see the docs.");
        }
    }

这是日志猫。

如果可以的话，我想抓住pay_key。

不太可能的错误：

对于生产应用程序，您真的希望将整个确认 JSON 发送到您的服务器。在那里可以对其进行解析，并且可以使用pay_keyorpayment_id来通过查询适当的 API 来获取交易详细信息。（见https://developer.paypal.com）

提供给移动设备的安全上下文更具限制性，因为该应用程序将安装在您无法控制的设备上。

有关更详细的说明，请参阅https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/ 。
