Google Pay API 是否可以检查用户是否已在 Google Pay 中添加了特定卡?我知道有一种检查用户是否可以付款的方法。
From official docs:
...调用isReadyToPay API以确定用户是否可以使用Google Pay API付款。
private void possiblyShowGooglePayButton() {
final Optional<JSONObject> isReadyToPayJson = PaymentsUtil.getIsReadyToPayRequest();
if (!isReadyToPayJson.isPresent()) {
return;
}
IsReadyToPayRequest request = IsReadyToPayRequest.fromJson(isReadyToPayJson.get().toString());
if (request == null) {
return;
}
// The call to isReadyToPay is asynchronous and returns a Task. We need to provide an
// OnCompleteListener to be triggered when the result of the call is known.
Task<Boolean> task = mPaymentsClient.isReadyToPay(request);
task.addOnCompleteListener(this,
new OnCompleteListener<Boolean>() {
@Override
public void onComplete(@NonNull Task<Boolean> task) {
if (task.isSuccessful()) {
setGooglePayAvailable(task.getResult());
} else {
Log.w("isReadyToPay failed", task.getException());
}
}
});
}
但是??上面的代码不适合我的需求。也许有人对此有解决方案?
答案 0 :(得分:0)
特定卡是什么意思?
documentation existingPaymentMethodRequired
很容易错过一件事。
默认情况下,API会检查设备/应用程序是否可用于付款,但通过existingPaymentMethodRequired
选项将检查用户是否具有可用于付款的现有付款方式
