Alexa Adapter - MVC and middleware

Hello BotBuilderCommunity!

I’m trying to use Alexa Adapter in .Net Core MVC. All works fine but I’m not able to use AlexaIntentRequestToMessageActivityMiddleware. It never transform Alexa Intent requests into MessageActivities.

My code looks like this:

public void ConfigureServices(IServiceCollection services)
{
	services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

	if (!string.IsNullOrEmpty(Configuration[BotOpenIdMetadataKey]))
		ChannelValidation.OpenIdMetadataUrl = Configuration[BotOpenIdMetadataKey];

	// Create the credential provider to be used with the Bot Framework Adapter.
	services.AddSingleton<ICredentialProvider, ConfigurationCredentialProvider>();

	services.AddSingleton<IChannelProvider, ConfigurationChannelProvider>();

	// Registering the AlexaHttpAdapter
	services.AddSingleton<IAlexaHttpAdapter>((sp) =>
	{
		var alexaHttpAdapter = new AlexaHttpAdapter(validateRequests: true)
		{
			OnTurnError = async (context, exception) =>
			{
				await context.SendActivityAsync("Sorry, something went wrong");
			},
			ShouldEndSessionByDefault = true,
			ConvertBotBuilderCardsToAlexaCards = false,
		};

		return alexaHttpAdapter;
	});

	services.AddSingleton<AlexaIntentRequestToMessageActivityMiddleware>();

	// Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
	services.AddTransient<IBot, AlexaAdapterBot>();
}

Do you have any suggestion how to make it working?

Hi Gary,

Thank for the clue. I update code and it works correctly now.

Code:

public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

            if (!string.IsNullOrEmpty(Configuration[BotOpenIdMetadataKey]))
                ChannelValidation.OpenIdMetadataUrl = Configuration[BotOpenIdMetadataKey];

            // Create the credential provider to be used with the Bot Framework Adapter.
            services.AddSingleton<ICredentialProvider, ConfigurationCredentialProvider>();

            services.AddSingleton<IChannelProvider, ConfigurationChannelProvider>();

            // Registering the AlexaHttpAdapter
            services.AddSingleton<IAlexaHttpAdapter>((sp) =>
            {
                var alexaHttpAdapter = new AlexaHttpAdapter(validateRequests: true)
                {
                    OnTurnError = async (context, exception) =>
                    {
                        await context.SendActivityAsync("Sorry, something went wrong");
                    },
                    ShouldEndSessionByDefault = true,
                    ConvertBotBuilderCardsToAlexaCards = false,
                };
                alexaHttpAdapter.Use(new AlexaIntentRequestToMessageActivityMiddleware());
                return alexaHttpAdapter;
            });

            services.AddSingleton<AlexaIntentRequestToMessageActivityMiddleware>();

            // Create the bot as a transient. In this case the ASP Controller is expecting an IBot.
            services.AddTransient<IBot, AlexaAdapterBot>();
        }

Cheers, Maciej

Hi.

Before this line…

ShouldEndSessionByDefault = true

You can insert

Use(new AlexaIntentRequestToMessageActivity())

That adds the middleware to the pipeline.

Cheers

Hi Arafat, Thank you for your response. I have checked Cortana Assistant Alexa Samplehttps://github.com/BotBuilderCommunity/botbuilder-community-dotnet/tree/develop/samples/Cortana Assistant Alexa Sample but it also doesn’t use MVC. I also checked Microsoft Sample Transcript Logger Middlewarehttps://github.com/Microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/17.multilingual-bot, it uses MVC and middleware. But I not able to find any clue why my code doesn’t work. Maciej — You are receiving this because you are subscribed to this thread.
