无法在 Azure 机器人框架中调用 Luis

Question

我是 dotnet 以及 Luis 和机器人框架的菜鸟。

我试图让一些机器人样本在我的机器上工作

https://github.com/microsoft/BotBuilder-Samples。

我对这个特别感兴趣

https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/13.core-bot

当我运行机器人时，它没有连接到 Luis（请参阅下面的错误消息）。

• 我通过导入应用程序中提供的意图在 Luis 中创建并发布了一个应用程序。
• 我在正确的 JSON 文件中写入了 LuisAppId、LuisAPIKey 和 LuisAPIHostName（见下文）。
• 我在项目中添加了 dotnet 库： dotnet add package Cognitive.LUIS.Programmatic

然后我只需cmd "dotnet run"在正确的文件夹中运行代码。

这里是app.setting JSON。我使用订阅密钥作为 LuisAPIKey，应用 ID 作为 LuisAppId。

{
  "MicrosoftAppId": "",
  "MicrosoftAppPassword": "",
  "LuisAppId": "2aa2b9c5-#######################7b557",
  "LuisAPIKey": "1069d###############4347da9",
  "LuisAPIHostName": "westus.api.cognitive.microsoft.com/luis/api/v2.0"
}

该机器人正在我的本地主机上运行。但它不起作用。

bot : 今天有什么可以帮到你的吗？像这样说“预订 2020 年 3 月 22 日从巴黎飞往柏林的航班”

我：“请预订 2020 年 3 月 22 日从巴黎飞往柏林的航班”

bot :“机器人遇到错误或错误。”

bot :“要继续运行此机器人，请修复机器人源代码”

如前所述，我对此很陌生，因此对上述内容的任何见解将不胜感激！

问题出在你的appsettings.json. 你需要你LuisAPIHostName是唯一的westus.api.cognitive.microsoft.com。如果这不起作用，请尝试westus。该示例经常更改，我们计划在 LUIS 发布其新 API 端点后在所有示例和文档中对其进行标准化。

这是示例自述文件中的说明

这是一个拉取请求，指出这个问题有多普遍

编辑：正如下面提到的@vikasramereddi，您还需要确保您的 LUIS 应用程序已发布到生产环境而不是暂存环境。
