Create a WebSite Chat bring me API Error

paule32.jk · October 5, 2024, 5:39pm

Hello,
I would create my own chat, and have two files (index.html, and server.php):

<!DOCTYPE html>
<html lang="de">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

        .chat-box { border: 1px solid #ccc; padding: 10px; width: 100%; max-width: 600px; height: 400px; overflow-y: scroll; }
        .input-area { margin-top: 10px; }
        .input-area input { width: 30%; padding: 10px; }
        .input-area button { padding: 10px 20px; }
    </style>
</head>
<body>
    <h1>ChatGPT Assistent</h1>
    
    <!-- API-Key Eingabeformular -->
    <div class="api-key-form">

        <button onclick="sendMessage()">Senden</button>
    </div>

    <script>
        // API-Key speichern
        function saveApiKey() {
            const apiKey = document.getElementById('api-key').value;
            if (apiKey) {
                localStorage.setItem('apiKey', apiKey); // Speichert den API-Key lokal
                alert("API-Key gespeichert!");
            } else {
                alert("Bitte API-Key eingeben.");
            }
        }
        
        // Funktion zum Hinzufügen von Nachrichten zum Chat
        function addMessageToChat(message, sender) {
            const chatBox = document.getElementById('chat-box');
            const messageElement = document.createElement('p');
            messageElement.textContent = sender + ": " + message;
            chatBox.appendChild(messageElement);
            chatBox.scrollTop = chatBox.scrollHeight;
        }

        function sendMessage() {
            const userInput = document.getElementById('user-input').value;
            if (userInput === "") return;

            // Benutzer-Nachricht anzeigen
            addMessageToChat(userInput, "Du");

            // API-Key aus dem lokalen Speicher abrufen
            const apiKey = localStorage.getItem('apiKey');
            if (!apiKey) {
                alert("Bitte einen API-Key eingeben.");
                return;
            }

            // AJAX-Anfrage an PHP-Datei senden
            const xhr = new XMLHttpRequest();
            xhr.open("POST", "server.php", true); // PHP-Datei angeben
            xhr.setRequestHeader("Content-Type", "application/json");

            xhr.onreadystatechange = function () {
                if (xhr.readyState === 4 && xhr.status === 200) {
                    const response = JSON.parse(xhr.responseText);
                    addMessageToChat(response.response, "Assistent");
                }
            };

            const data = JSON.stringify({ message: userInput, apiKey: apiKey });
            xhr.send(data);

            // Eingabefeld zurücksetzen
            document.getElementById('user-input').value = '';
        }
    </script>
</body>
</html>

and the php file server.php

<?php
// POST-Daten empfangen
$data = json_decode(file_get_contents('php://input'), true);
$user_message = $data['message'];
$api_key = $data['apiKey']; // Den API-Key aus der Anfrage abrufen

if (!$api_key) {
    echo json_encode(['response' => 'Kein API-Key vorhanden.']);
    exit();
}

// Anfrage an OpenAI senden
$openai_url = 'https://api.openai.com/v1/completions';
$prompt = "User: $user_message\nAI:";

$options = [
    'http' => [
        'header' => [
            "Content-Type: application/json",
            "Authorization: Bearer $api_key",
        ],
        'method' => 'POST',
        'content' => json_encode([
            'prompt' => $prompt,
            'max_tokens' => 150,
            'temperature' => 0.7,
            'model' => 'gpt-3.5-turbo'
        ]),
    ]
];

$context = stream_context_create($options);
$response = file_get_contents($openai_url, false, $context);

// Antwort parsen und zurückgeben
if ($response === FALSE) {
    $error = error_get_last();  // Detaillierte Fehlernachricht abrufen
    echo json_encode(['response' => 'Fehler beim Abrufen der Antwort von der OpenAI API.', 'error' => $error]);
    exit();
}   else {
    $result = json_decode($response, true);
    $assistant_response = $result['choices'][0]['text'];
    echo json_encode(['error' => trim($assistant_response)]);
}

when I go to the browser, and save the api key, I get Error on Line: “if ($response === FALSE) {”.
So the Question is, how can I setup API and or fix the logging problem ?

Heya. Welcome back. Good to see you again.

Are you getting an error message? I haven’t looked at your code, but checking the return object for an error message or checking server error logs might help.

paule32.jk · October 5, 2024, 6:22pm

paule32.jk:

// Antwort parsen und zurückgeben
if ($response === FALSE) {
    $error = error_get_last();  // Detaillierte Fehlernachricht abrufen
    echo json_encode(['response' => 'Fehler beim Abrufen der Antwort von der OpenAI API.', 'error' => $error]);
    exit();

above the response: “Fehler beim Abrufen der Antwort von der OpenAI API.”
This is German, and translated to English: “Error during request the response from the OpenAI API.”

So, it looks like the API-key does not fit in case.
I have create a new security project key (user keys are out of date), copied this to the clipboard, and from there into the HTML Application.

Then save the key with the “Speichern” Button.
And when I enter text into the input line, and click the send button, the response will be empty.

Either my code is wrong, or something else goes on there.

PaulBellow · October 5, 2024, 6:25pm

I’d try to get the error code in the response, but it sounds like a 429 or you didn’t set the new API key up with the right permissions?

Here’s a list of all the error codes for reference…

https://platform.openai.com/docs/guides/error-codes

I’m guessing one of these?

401 - Incorrect API key provided Cause: The requesting API key is not correct.
Solution: Ensure the API key used is correct, clear your browser cache, or generate a new one.
401 - You must be a member of an organization to use the API Cause: Your account is not part of an organization.
Solution: Contact us to get added to a new organization or ask your organization manager to invite you to an organization.
403 - Country, region, or territory not supported Cause: You are accessing the API from an unsupported country, region, or territory.
Solution: Please see this page for more information.
429 - Rate limit reached for requests Cause: You are sending requests too quickly.
Solution: Pace your requests. Read the Rate limit guide.
429 - You exceeded your current quota, please check your plan and billing details Cause: You have run out of credits or hit your maximum monthly spend.
Solution: Buy more credits or learn how to increase your limits.

I check the error result:

file_get_contents(https://api.openai.com/v1/completions): Failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found

so the api url is not correct ?

PaulBellow · October 5, 2024, 7:03pm

Sounds like it. Sorry, I didn’t look closely at your code.

I’d check Model Endpoint Compatibility in the docs.

https://platform.openai.com/docs/models/model-endpoint-compatibility

Are you using old code?

Think you need to use cURL and not send POST request…

I’d look around for current example. The API Docs should have current PHP code… or cURL…

yes, a little bit extended:

I don’t have a ton of time at the moment, but I would check the docs.

I shared some PHP / cURL code here but for DALLE model…

Might give you some pointers, though!

Everything is laid out well here…
