Creating a Laravel ChatGPT Controller:

4.1 Installing Guzzle for API Requests:

Guzzle is a powerful HTTP client for making API requests. Install it using Composer:

composer require guzzlehttp/guzzle

4.2 Laravel Controller Setup:

Create a new controller using the Artisan command:

php artisan make:controller ChatGPTController

Open the ChatGPTController.php file in the app/Http/Controllers directory and set up the basic structure:

// app/Http/Controllers/ChatGPTController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use GuzzleHttp\Client;

class ChatGPTController extends Controller
{
    private $gptApiKey;

    public function __construct()
    {
        $this->gptApiKey = config('services.openai.api_key');
    }

    public function interactWithChatGPT(Request $request)
    {
        $userInput = $request->input('user_input');

        $response = $this->makeChatGPTRequest($userInput);

        $chatbotResponse = $this->processChatGPTResponse($response);

        return response()->json(['response' => $chatbotResponse]);
    }

    private function makeChatGPTRequest($userInput)
    {
        $client = new Client();

        $response = $client->post('https://api.openai.com/v1/chat/completions', [
            'headers' => [
                'Content-Type' => 'application/json',
                'Authorization' => 'Bearer ' . $this->gptApiKey,
            ],
            'json' => [
                'messages' => [
                    ['role' => 'system', 'content' => 'You are a helpful assistant.'],
                    ['role' => 'user', 'content' => $userInput],
                ],
            ],
        ]);

        return json_decode($response->getBody(), true);
    }

    private function processChatGPTResponse($response)
    {
        return $response['choices'][0]['message']['content'];
    }
}

In this controller, we handle user inputs, make a request to the OpenAI API, and process the response. Adjust the code based on your application’s needs.
