Alexa accessToken JWT是否已编码？

Question

以Alexa技能配置OAuth 2.0后，我在Alexa请求中看到了accessCode值：

}

但是此代码似乎不是有效的JWT令牌：

是这样，还是我做错了什么（也许提供了不同的算法）？

Alexa的`accessToken'是否符合任何令牌标准？

谢谢。

Answer 1

Alexa刚刚传递了从授权服务器收到的 artifacts: paths: - dist 。完全取决于授权服务器发出哪种令牌。

  

访问令牌是代表最终用户的凭证   （资源所有者）在另一个系统中。令牌应标识用户   在另一个系统中。

如果帐户链接成功，Alexa现在将存储一个访问令牌（由另一个系统提供），该令牌用于标识另一个系统中的用户。现在，此令牌已包含在对该技能的所有请求中，因此该技能可以在需要时访问其他系统中的用户信息。
