我正在使用 Prime[31] 插件在 Unity 中测试一个应用程序，用户可以在其中购买声音。如果单击声音按钮，PurchasableSound则会调用一个 .cs 文件来确定声音是否已购买。（仅供参考，它尝试使用 来做到这一点PlayerPrefs.GetInt，但是，我还没有设法让它工作）。如果声音还没有被购买，我会调用另一个 .cs 文件，PurchaseSounds它会统一激活一个面板，用户可以在其中选择购买所有可购买的声音中的 4 个或 10 个。在那段代码中，GoogleIAB.init(key)和GoogleIAB.queryInventory(skus)被执行并且可以购买上述两种产品中的一种。
但是，在我的 Android 设备上执行整个场景期间，Signature verification失败了：

我不明白为什么会这样。我很确定我添加的 Base64 许可证密钥没有任何问题。基于09-06 18:10:12.332: I/Unity(10536): billingSupportedEvent，GoogleIAB 初始化，但queryInventoryFailedEvent: Error refreshing inventory (querying owned items). (response: -1003:Purchase signature verification failed)很明显我的 sku 无法获取。出了什么问题，为什么？这是否与错误填写的 Unity 中的密钥库或密钥设置有关？
