本頁面說明如何使用範例代碼測試整合結果。
產生範例代碼
直接整合時，為了在伺服器中測試代碼解密功能，您可以在建立 PaymentsClient 執行個體時將環境設為 ENVIRONMENT_TEST 來產生範例代碼。
如果您在設為 ENVIRONMENT_TEST 的環境中建立 PaymentsClient 執行個體，傳送至 loadPaymentData 的呼叫可以照常運作，並會要求使用者選取一張真的卡片。不過，系統絕對不會傳回所選卡片的實際資訊，且產生的權杖一律會有固定的酬載。
驗證簽名
在 ENVIRONMENT_TEST 中產生的代碼會使用之前傳送至 Google 的測試公開金鑰加密。
系統會利用 Google 的測試金鑰簽署權杖。如果您使用的是 Tink，建議您在建立 PaymentMethodTokenRecipient 物件時設定 .fetchSenderVerifyingKeysWith(GooglePaymentsPublicKeysManager.INSTANCE_TEST)。
解密酬載
範例代碼解密完成後，您會收到純文字酬載。酬載的結構取決於所選卡片是否已代碼化，即是否已新增至 Google Pay。另外，視卡片網路為何，代碼化卡片的酬載可能會有所不同。不過，無論卡片網路為何，非代碼化卡片的酬載一律相同。
相較於下列範例，已解密酬載的以下三個欄位可能不同：
messageExpiration：距離目前時間的一週後。messageId：系統為各項酬載隨機產生的識別碼。expirationYear：設定在目前年分的五年之後。
已解密酬載結構可能採用的通訊協定版本共有兩種：ECv1 和 ECv2。如果您執行的是新版整合作業，則版本為 ECv2。如果無法確定通訊協定版本，請洽詢您的 Google 聯絡窗口。
