Question

我正在使用braintree rails dropin，只有我的第一笔交易成功反映在沙箱管理员中。我注意到每次调用时在控制器上生成的客户端令牌都是相同的。这是一个错误还是应该每次生成相同的令牌。我没有在文档中看到有关此问题的任何内容。

每次调用Braintree API时，客户端令牌都是唯一的。如果没有生成代码或示例令牌，则无法确认或解决此问题。但我怀疑这并没有真正发生。我怀疑你可能会看到它几乎完全一样。您可以在irb：

中对此进行测试

客户端令牌是一团数据，as the documentation says包含客户端初始化客户端SDK以与Braintree通信所需的所有授权和配置信息。在引擎盖下，您可以看到当前客户端令牌是base-64编码数据类型，其中包含一串Json。如果您看到authorizationFingerprint：

，很容易看出它们是唯一的

如果您没有看到不同的authorizationFingerprints，我会立即与Braintree Support联系。
