Question

我们在最新的Bot SDK中为客户构建了一个漫游器，但在对话开始时随机出现“未经授权”错误。

看到下面的错误，这很奇怪，因为：

这种情况很少发生
并且错误是从漫游器发送的，因此DirectLine API已经与漫游器进行了通信，但是漫游器无法将任何东西发送回DirectLine。（这是我们假设的，但很难调试）

我们仍然在MemoryStorage上，但不要认为这与它有任何关系。

框架版本：

.net core 2.2
bot.builder = 4.1.5

“这可能是v4 SDK中的令牌缓存错误。上一版本，在V3 C＃SDK中，我们不再使用自定义代码，而是使用AAD团队提供的交钥匙解决方案。到目前为止，似乎运行良好，并且我们对该解决方案感到满意。作为这项工作的一个不错的副作用，在非常高的负载下的性能也要好很多。

这项工作目前正在v4 C＃SDK中进行，并计划于2月中旬在4.3版本中进行。”
