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，对于我来说，我无法获得 PayPal 交易细节。我在 LogCat 中看到了详细信息，但无论我尝试什么，我都无法捕获任何东西。我知道这必须很简单，但我一直坐在这里，每一次尝试都没有结果。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 开发者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 logcat。

如果可以，我想拿到 pay_key。

最佳答案
对于生产应用程序，您确实希望将整个确认 JSON 发送到您的服务器。它可以在那里被解析，pay_key 或 payment_id 可用于通过查询适当的 API 来获取交易详细信息。 (参见 https://developer.paypal.com)
赋予移动设备的安全上下文更加严格，因为应用程序将安装在您无法控制的设备上。
参见 https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/以获得更详细的解释。
