本页介绍了如何使用示例令牌来测试集成。
生成示例令牌
对于直接集成，若要在您的服务器上测试令牌解密，您可以在构建 PaymentsClient 实例时通过设置 ENVIRONMENT_TEST 来生成示例令牌。
当您在环境设为 ENVIRONMENT_TEST 的情况下构建 PaymentsClient 实例时，对 loadPaymentData 的调用会照常执行，并会要求用户选择一张真实的卡。不过，这样其实并不会返回所选卡的实际信息，而且产生的令牌始终具有恒定载荷。
验证签名
在 ENVIRONMENT_TEST 中生成的令牌会使用您之前发送给 Google 的测试公钥进行加密。
这些令牌使用 Google 的测试密钥签名。如果您使用 Tink，请确保在构建 PaymentMethodTokenRecipient 对象时设置了 .fetchSenderVerifyingKeysWith(GooglePaymentsPublicKeysManager.INSTANCE_TEST)。
解密载荷
解密示例令牌后，您将收到明文载荷。载荷结构取决于所选卡是否已被令牌化（即已添加到 Google Pay）。此外，令牌化卡的载荷是不同的，具体取决于支付卡网络。无论支付卡网络为何，非令牌化卡的载荷都始终相同。
与以下示例相比，解密载荷中的以下三个字段可能会有所不同：
messageExpiration：已设为自当前时间起的一周后。messageId：这是为每个载荷随机生成的。expirationYear：设为自当前年份起的五年后。
使用的协议版本（ECv1 和 ECv2）不同，解密载荷的结构也有所不同。如果您要实现新的集成，请使用 ECv2 版本。如果您不确定该使用哪个协议版本，请与您的 Google 联系人联系确认。
