Я использую. Net Core 2.1 для сборки бота с версией 4, как в примере здесь , и я не получаю никакого ответа от эмулятора Bot Framework или ошибки кода из Visual Studio. Когда я go из URL, это говорит об этой ошибке на изображении ниже. Я думаю, что-то не так с внедрением зависимости. Что я делаю не так?
При запуске:
public class Startup
{
public Startup(IConfiguration configuration, IHostingEnvironment env)
{
Configuration = configuration;
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
configuration = builder.Build();
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
// Create the Bot Framework Adapter with error handling enabled.
services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();
// Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
// services.AddTransient<IBot, MyBot>();
// Create the credential provider to be used with the Bot Framework Adapter.
services.AddSingleton<ICredentialProvider, ConfigurationCredentialProvider>();
// Create the Bot Framework Adapter.
// storage
services.AddSingleton<IStorage, MemoryStorage>();
// Create the User state. (Used in this bot's Dialog implementation.)
services.AddSingleton<UserState>();
services.AddSingleton<RootDialog>();
services.AddTransient<IBot, DialogBot<RootDialog>>();
// Create the Conversation state. (Used by the Dialog system itself.)
services.AddSingleton<ConversationState>();
services.AddSingleton(Configuration);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseWebSockets();
app.UseMvc();
app.UseBotFramework();
}
}
В DialogBot.cs:
public class DialogBot<T>: ActivityHandler where T : Dialog
{
protected readonly BotState ConversationState;
protected readonly Dialog Dialog;
protected readonly ILogger Logger;
protected readonly BotState UserState;
public DialogBot(ConversationState conversationState, UserState userState, T dialog, ILogger<DialogBot<T>> logger)
{
ConversationState = conversationState;
UserState = userState;
Dialog = dialog;
Logger = logger;
}
public override async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
await base.OnTurnAsync(turnContext, cancellationToken);
// Save any state changes that might have occured during the turn.
await ConversationState.SaveChangesAsync(turnContext, false, cancellationToken);
await UserState.SaveChangesAsync(turnContext, false, cancellationToken);
}
protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
Logger.LogInformation("Running dialog with Message Activity.");
// Run the Dialog with the new message Activity.
await Dialog.RunAsync(turnContext, ConversationState.CreateProperty<DialogState>(nameof(DialogState)), cancellationToken);
}
protected override async Task OnMembersAddedAsync(IList<ChannelAccount> membersAdded, ITurnContext<IConversationUpdateActivity> turnContext, CancellationToken cancellationToken)
{
foreach (var member in membersAdded)
{
if (member.Id != turnContext.Activity.Recipient.Id)
{
await turnContext.SendActivityAsync(MessageFactory.Text($"Welcome!"), cancellationToken);
}
}
}
In RootDialog.cs:
[Serializable]
public class RootDialog : ComponentDialog
{
protected readonly ILogger _logger;
protected readonly Dialog _dialog;
protected readonly BotState _conversationState;
protected readonly AdapterWithErrorHandler _adapterWithErrorHandler;
protected readonly Encryption _encryption;
private readonly IConfiguration _iConfiguration;
public RootDialog(ConversationState conversationState, Dialog dialog,ILogger<RootDialog> Logger, AdapterWithErrorHandler AdapterWithErrorHandler, Encryption Encryption, IConfiguration configuration)
{
_conversationState = conversationState;
_dialog = dialog;
_logger = Logger;
_adapterWithErrorHandler = AdapterWithErrorHandler;
_encryption = Encryption;
_iConfiguration = configuration;
}
const string HeroCard = "Hero Card";
const string ThumbnailCard = "Thumbnail Card";
private async Task<DialogTurnResult> StartDialogAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
// Start the child dialog. This will run the top slot dialog than will complete when all the properties are gathered.
return await stepContext.BeginDialogAsync("slot-dialog", null, cancellationToken);
}
}
