azure - 无法在 Azure 机器人框架中调用 Luis

Question

我是 dotnet 以及 Luis 和 bot 框架的菜鸟。

我正在尝试让一些机器人示例在我的机器上工作

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，它无法连接到 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)。
• 我将 dotnet 库添加到项目中:dotnet add package Cognitive.LUIS.Programmatic

然后，我只需在正确的文件夹中使用 cmd“dotnet run” 运行代码即可。

这里是 app.setting JSON。我使用订阅 key 作为 LuisAPIKey，使用应用程序 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。但它就是行不通。

bot : What can I help you with today? Say something like “Book a flight from Paris to Berlin on March 22, 2020”

me : “Please Book a flight from Paris to Berlin on March 22, 2020”

bot :"The bot encounted an error or bug."

bot :"To continue to run this bot, please fix the bot source code"

On the cmd line :

正如我所提到的，我对此很陌生，因此对上述内容的任何见解将不胜感激!

问题出在您的 appsettings.json 中。您只需将 LuisAPIHostName 设为 westus.api.cognitive.microsoft.com。如果这不起作用，请尝试 westus。该示例经常更改，一旦 LUIS 发布其新的 API 端点，我们计划在所有示例和文档中对其进行标准化。

Here's the instructions in the Sample README

Here's a Pull Request noting how common this issue is

编辑:正如@vikasramereddi 下面提到的，您还需要确保您的 LUIS 应用发布到 Production 而不是 Staging。
