c# - 路易斯异常 : Operation returned an invalid status code 'Forbidden'

Question

出现这样的错误。早些时候，只是有时而已。现在，即使是简单的“嗨”，它也给了我这个异常(exception)。

请帮忙。

尽管最初的问题不符合 mcve ，使用 LUIS 时有两个与 403 相关的常见陷阱。

创作/订阅 key 错误或没有

使用 LUIS 处理来自 Web 的示例时，您必须从 LUIS 应用提供订阅和创作 key 。在最新的机器人构建器示例中，它通常位于 *.bot 文件中，如下所示 here .

official documentation 中描述了创作键和查询的概念。 .

403 未通话通话量配额

您已达到 LUIS 启动 key 的配额限制。为了永久解决这个问题，请按照我的指导 here .
