ASP.NET Core Chatbot with ChatGPT

Cenk 991

Hi there;

I wonder if there is a way to limit a chatbot application to only chatting about a specific topic. Are there any examples that I can use on this topic with ASP.NET Core web application?

Thank you.

Nope, trying to use chatgpt api, here is a sample.

@page "/"
@using Newtonsoft.Json;
@using System.Text;
@inject ILogger<Index> _logger

<PageTitle>Chatbot</PageTitle>

<div class="container">
    <div class="row">
        <div class="col-4">
            <p>@testing</p>
        </div>
        <div class="col-4">
            <div class="messages">
                @for (int i = 0; i < messages.Count; i++)
                {
                    @if (i % 2 == 0)
                    {
                        <div class="question">@messages[i]</div>
                    } else
                    {
                        <div class="response">@messages[i]</div>
                    }
                }
                
            </div>
            <div class="textMessage">
                <input @bind="message" />
                <button @onclick="SendMessage">Send</button>
            </div>
        </div>
        <div class="col-4">
        </div>

    </div>
</div>

@code{
    public string message;
    public string testing;
    public List<string> messages = new List<string>();
    private static HttpClient Http = new HttpClient();

    protected override async Task OnInitializedAsync()
    {

    }

    public async Task SendMessage()
    {
        Http = new HttpClient();
        messages.Add(message);

             var apiKey = "sk-1234";
        Http.DefaultRequestHeaders.Add("Authorization", $"Bearer {apiKey}");

        // JSON content for the API call
        var jsonContent = new
        {
            prompt = message,
            model = "text-davinci-003",
            max_tokens = 350,
            temperature = 0.9,
            top_p = 1,
        };
        try
        {
            // Make the API call
            var responseContent = await Http.PostAsync("https://api.openai.com/v1/chat/completions", new StringContent(JsonConvert.SerializeObject(jsonContent), Encoding.UTF8, "application/json"));

            // Read the response as a string
            var resContext = await responseContent.Content.ReadAsStringAsync();
            // Deserialize the response into a dynamic object
            var data = JsonConvert.DeserializeObject<dynamic>(resContext);
            messages.Add(data.choices[0].text ?? "An error occurred while processing your request.");
            StateHasChanged();
        }
        catch (Exception exception)
        {
            _logger.LogError(exception.Message);
            messages.Add("An error occurred while processing your request.");
            StateHasChanged();
        }
        

        
    }
}
