使用示例令牌进行测试

本页介绍了如何使用示例令牌来测试集成。

生成示例令牌

若要在您的服务器上测试令牌解密以进行直接集成，您可以在构建 PaymentsClient 实例时将环境设置为 TEST，以生成示例令牌。

当您在环境设为 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。

重要提示：当环境设为 TEST 时，系统永远不会使用您的卡的真实详细信息，但您必须至少向您的 Google 帐号添加一张可扣款的卡才能继续操作。此外，要为令牌化的卡生成示例令牌，您需要安装 Google Pay 应用并至少向其中添加一种支持的付款方式。

验证签名

在 TEST 环境中生成的令牌会使用您先前发送给 Google 的测试公钥进行加密。

这些令牌使用 Google 的测试密钥进行签名。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（即是否已添加到 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。

与此页面中的示例相比，解密载荷中的以下三个字段可能会有所不同：

messageExpiration：此字段是一个设为一周后（从当前时间算起）的时间戳。
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。
