Ruby on rails 在Ruby中获取NoMethodError未定义方法

在有效的\u限制下获取

NoMethodError未定义的方法服务\u帐户\u id

？方法。 有人能检查一下我为什么会出现这个错误吗

如果你有解决这个问题的链接，那也会很有帮助。谢谢 错误： 错误：

请显示完整的错误，而不仅仅是一个片段。这可能是

nil

，也可能是该对象上不存在您认为存在的方法。@tadman错误：如果该标记是

字符串

，那么您将无法对其调用任意方法，是吗？你确定那是正确的类型吗？也许你的“解码令牌”实际上没有被解码。@tadman解码的令牌基本上是一个GCP身份令牌（jwt有效负载）…似乎不是这样。你确定你解码了吗？您确定在传递该变量之前已将解码结果赋给该变量吗？
