Google Pay 谷歌支付（gateway = stripe）
Google pay 國際版開發
一、官網地址（科學上網）
官方對接文件 https://developers.google.com/pay/api/android/overview
Stripe對接Google Pay https://stripe.com/docs/google-pay
Stripe驗證支付 https://stripe.com/docs/payments/accept-a-payment?integration=elements
Stripe管理後臺 https://dashboard.stripe.com/dashboard
二、接入流程
三、主要流程
1、伺服器請求orderId
2、呼叫Google Pay
3、通過Stripe完成支付
4、伺服器完成驗證
四、主要程式碼實現（1、4主要是伺服器流程，以下主要是2、3流程）
專案配置
build.gradle 新增
implementation 'com.google.android.gms:play-services-wallet:18.1.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.stripe:stripe-android:16.0.1'
AndroidManifest.xml 的 application新增
<meta-data
android:name="com.google.android.gms.wallet.api.enabled"
android:value="true" />
呼叫Google Pay
@RequiresApi(api = Build.VERSION_CODES.N)
private void payWithGoogle( double price) {
if (paymentsClient == null) {
paymentsClient = createPaymentsClient(mActivity);
}
// 主要是Google Pay一些引數設定
Optional<JSONObject> paymentDataRequestJson = createPaymentDataRequest(price);
if (!paymentDataRequestJson.isPresent()) {
return;
}
PaymentDataRequest request =
PaymentDataRequest.fromJson(paymentDataRequestJson.get().toString());
if (request != null) {
if (mActivity!=null){
mActivity.showCircle2Loading();
}
// 調起 Google Pay
AutoResolveHelper.resolveTask(
paymentsClient.loadPaymentData(request),
mActivity,
LOAD_PAYMENT_DATA_REQUEST_CODE
);
}
}
Google Pay 基本設定
```
@RequiresApi(api = Build.VERSION_CODES.N)
private Optional
} catch (JSONException e) {
return Optional.empty();
}
}
private JSONObject getCardPaymentMethod() throws JSONException { JSONObject cardPaymentMethod = getBaseCardPaymentMethod(); // 設定stripe為付款方式 JSONObject tokenizationSpec = new GooglePayConfig(LIVE_API).getTokenizationSpecification(); cardPaymentMethod.put("tokenizationSpecification", tokenizationSpec); return cardPaymentMethod; }
/**

*/
private JSONObject getTransactionInfo(double price) throws JSONException {
JSONObject transactionInfo = new JSONObject();
transactionInfo.put("totalPrice", price+"");
transactionInfo.put("totalPriceStatus", "FINAL");
transactionInfo.put("countryCode", COUNTRY_CODE);
transactionInfo.put("currencyCode", CURRENCY_CODE);
transactionInfo.put("checkoutOption", "COMPLETE_IMMEDIATE_PURCHASE");
return transactionInfo;
}
/**

*/
private JSONObject getMerchantInfo() throws JSONException {
return new JSONObject().put("merchantName", "Guruji").put("merchantId", "填寫商家ID");
}
private JSONObject getBaseRequest() throws JSONException {

.put("apiVersion", 2)
