我长期使用 Unity IAP 购买消耗品和非消耗品的产品，但客户决定在项目中也使用订阅。
自从我使用 Unity IAP 以来，我认为最好的方法是将其也用于订阅，因此我在当前的购买者类中实现了订阅要求，如下所示：

我在 Play 管理中心创建了订阅 ID，从控制台复制了该 ID 并将其粘贴到 IAP 目录中，然后我还创建了收据验证器混淆器。
现在，当我构建项目并检查日志时，可用产品向我显示了包括订阅在内的所有三个产品，但是当我购买订阅时，它会显示错误提示：
购买失败：产品 (com.test.google.weekly) 不可用。
我不知道我在这里做错了什么，我三次检查了 ID、公共 API 密钥和密钥库，一切正常，但总是重复
答案 0 :(得分：2)
