I can't log in to send messages to the chat

Hiya, what's the issue, are you getting any error messages?

Yes, I get a message that there is no authorization. In the end, I decided not to use a token at all and just send a message to the chat.
The message is sent, but the link is not active. And I wanted people from the chat to follow the link and write in the chat what kind of bird it is.
I'm struggling with how to make the link active.
I use this code.

// Отправка ссылки на изображение птички
app.get('/birdgame', (req, res) => {
  currentBird = getRandomBird(); // Обновляем текущую птичку при каждом запросе
  const host = req.hostname; // Получаем имя хоста
  const port = req.socket.localPort; // Получаем порт, на котором работает сервер
​
​
// Формируем строку сообщения вместо объекта
//const message = `<a href="http://${host}:${port}/photo/${currentBird.image}">Отгадай, какая это птица!</a>`;
//const message = `http://${host}:${port}/photo/${currentBird.image}`;
//const message = `http://${host}:${port}/photo/${currentBird.image} Отгадай, какая это птица!`;
​
 const message = `http://${host}:${port}/photo/${currentBird.image}`.trim();
  // Отправляем строку, а не JSON
  res.send(message);
​
  //res.json({
  //  imageURL: `http://${host}:${port}/photo/${currentBird.image}`, // Формируем ссылку с портом
  //  message: 'Отгадай, какая это птица!'
  //});
});
Maybe I don't need to get a token to write a message in the chat.
Now I would like to understand why the link in the chat is not active.
The code shows that I tried different options.
Maybe it's the night bot that doesn't allow you to insert links without authorization. I haven't figured it out yet(.

Here's an example with axios from chat gpt:

const axios = require('axios');
const qs = require('qs');
​
// Replace with your client credentials
const clientId = 'YOUR_CLIENT_ID';
const clientSecret = 'YOUR_CLIENT_SECRET';
​
// Obtain OAuth token using Client Credentials Grant with `channel_send` scope
async function getAccessToken() {
    const tokenUrl = 'https://api.nightbot.tv/oauth2/token';
    const data = {
        grant_type: 'client_credentials',
        client_id: clientId,
        client_secret: clientSecret,
        scope: 'channel_send', // Ensure you request the `channel_send` scope
    };
​
    try {
        const response = await axios.post(tokenUrl, qs.stringify(data), {
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded',
            },
        });
​
        return response.data.access_token;
    } catch (error) {
        console.error('Error fetching access token:', error.response ? error.response.data : error.message);
    }
}
​
// Example function to send a message as Nightbot
async function sendMessage(accessToken, message) {
    const nightbotApiUrl = 'https://api.nightbot.tv/1/channel/send';
​
    try {
        const response = await axios.post(
            nightbotApiUrl,
            { message },
            {
                headers: {
                    Authorization: `Bearer ${accessToken}`,
                },
            }
        );
​
        console.log('Message sent successfully:', response.data);
    } catch (error) {
        console.error('Error sending message:', error.response ? error.response.data : error.message);
    }
}
​
// Example usage
(async () => {
    const accessToken = await getAccessToken();
    if (!accessToken) return;

​
    const message = 'Hello from Nightbot via Client Credentials!';
​
    await sendMessage(accessToken, message);
})();
