我需要一些帮助。我是 Azure 机器人框架开发新手，几周前使用 QnA 知识库创建了我的第一个聊天机器人。无论如何，我设法在 Azure 门户中创建了机器人，并且它运行良好。但我需要在 Bot Framework Emulator（使用 V4）中进行一些更改和测试，为此，需要在本地下载并运行我的机器人。
我按照 Azure 的说明下载了机器人的 .zip 文件，并使用 Visual Studio 2017 作为 IDE 对其进行了初始化。但是，当我点击“调试”按钮时，程序会尝试连接到本地主机:3984.
using Autofac;
using System.Web.Http;
using System.Configuration;
using System.Reflection;
using Microsoft.Bot.Builder.Azure;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Internals;
using Microsoft.Bot.Connector;
namespace SimpleEchoBot
{
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
// Bot Storage: This is a great spot to register the private state storage for your bot.
// We provide adapters for Azure Table, CosmosDb, SQL Azure, or you can implement your own!
// For samples and documentation, see: https://github.com/Microsoft/BotBuilder-Azure
Conversation.UpdateContainer(
builder =>
{
builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));
// Using Azure Table Storage
var store = new TableBotDataStore(ConfigurationManager.AppSettings["AzureWebJobsStorage"]); // requires Microsoft.BotBuilder.Azure Nuget package
// To use CosmosDb or InMemory storage instead of the default table storage, uncomment the corresponding line below
// var store = new DocumentDbBotDataStore("cosmos db uri", "cosmos db key"); // requires Microsoft.BotBuilder.Azure Nuget package
// var store = new InMemoryDataStore(); // volatile in-memory store
builder.Register(c => store)
.Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
.AsSelf()
.SingleInstance();
});
GlobalConfiguration.Configure(WebApiConfig.Register);
}
}
}
不过，几秒钟后，以下代码行就会返回错误System.ArgumentNullException: '值不能为空。 Arg_ParamName_Name':
var store = new TableBotDataStore(ConfigurationManager.AppSettings["AzureWebJobsStorage"]); // requires Microsoft.BotBuilder.Azure Nuget package
因此，我无法在 Bot Framework Emulator 中测试我的机器人。由于我对 C# 非常陌生，有人可以帮我解决这个问题吗？
EDIT：这是我的 web.config 部分代码，只是删除了敏感数据：

As the error mentions, the problem here is that, AzureWebJobsStorage cannot be found in the web.config file. To fix your problem, navigate to your bot in azure portal and click on app settings from the left blade. There you will find a setting with the key AzureWebJobsStorage.
Copy the value of the setting and paste that in the web.config file as :
<configuration>
<appSettings>
<!-- update these with your BotId, Microsoft App Id and your Microsoft App Password-->
<add key="BotId" value="YourBotId" />
<add key="MicrosoftAppId" value="" />
<add key="MicrosoftAppPassword" value="" />
<add key="QnaSubscriptionKey" value="" />
<add key="QnaKnowledgebaseId" value="" />
<add key="AzureWebJobsStorage" value="copied value from azure portal" />
</appSettings>
Update:
为了回答您在评论中提出的进一步问题，
我被重定向到浏览器中的空白页面，其中包含地址 localhost:3984 和可在其中阅读 QnABot 模板的文本，后面是一些链接
表示机器人现在工作正常，这实际上是预期的行为。 要在本地测试机器人，您需要使用机器人模拟器 https://learn.microsoft.com/en-us/azure/bot-service/bot-service-debug-emulator?view=azure-bot-service-3.0。按照链接中提到的步骤操作并测试机器人。您也可以通过机器人框架 https://learn.microsoft.com/en-us/azure/bot-service/?view=azure-bot-service-3.0链接，因为这将使您更清楚地了解 Microsoft Bot Framework。
更新2：
根据您发布的屏幕截图，我认为您已经更改了Global.asax文件。
注册代码TableBotDataStore应该正是
var store = new TableBotDataStore(ConfigurationManager.AppSettings["AzureWebJobsStorage"]);
对此没有任何改变。
其次，正如韩非所说：
The
Utils.GetAppSetting(string key)方法适用于在 Azure 上运行的机器人，如果您想在本地运行机器人应用程序并从 web.config 文件访问设置，您可以使用ConfigurationManager.AppSettings[“your_key”]取代Utils.GetAppSetting(“your_key”)在您的 QnAMakerDialog 中。
第二个屏幕截图显示您仍然有Utils.GetAppSetting(“your_key”)在你的代码中。将其替换为：
var qnaKBId = ConfigurationManager.AppSettings["QnAKnowledgebaseId"];
其他地方也是如此。
