无法在 Azure 机器人框架中调用 Luis

Question

我是 dotnet 以及 Luis 和 bot 框架方面的菜鸟。

我正在尝试让一些机器人样本在我的机器上运行

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）。
我将 dotnet 库添加到项目中：dotnet add package Cognitive.LUIS.Programmatic

然后我只是运行正确文件夹中带有 cmd "dotnet run" 的代码。

这里是app.settingJSON。我将订阅密钥用作 LuisAPIKey，并将应用程序 ID 用作 LuisAppId。

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

机器人运行正在我的本地主机上运行。但这就是行不通。

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 :

如前所述，我是新手，所以对以上内容的任何见解都将不胜感激！

问题出在您的 appsettings.json 上。您只需要 LuisAPIHostName 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 发布其新的 API 终结点后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：正如下面提到的@vikasramereddi，您还需要确保您的 LUIS 应用已发布到生产环境而不是暂存环境。
