Extracting values from API data in node.js-CodePudding

Thank you for your time. I'm trying to use OAuth2 in discord, but I'm having a hard time figuring out how to retrieve the username. Can someone please tell me how to do it?

code

const fetch = require('node-fetch');
const express = require('express');

const app = express();

app.get('/', async ({ query }, response) => {
    const { code } = query;

    if (code) {
        try {
            const oauthResult = await fetch('https://discord.com/api/oauth2/token', {
                method: 'POST',
                body: new URLSearchParams({
                    client_id: process.env['ci'],
                    client_secret: process.env['cs'],
                    code,
                    grant_type: 'authorization_code',
                    redirect_uri: `https://oauth.aiueominato1111.repl.co`,
                    scope: 'identify',
                }),
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded',
                },
            });

            const oauthData = await oauthResult.json();

            const userResult = await fetch('https://discord.com/api/users/@me', {
                headers: {
                    authorization: `${oauthData.token_type} ${oauthData.access_token}`,
                },
            });
            console.log( await userResult.json());
        } catch (error) {
            // NOTE: An unauthorized token will not throw an error;
            // it will return a 401 Unauthorized response in the try block above
            console.error(error);
        }
    }

    return response.sendFile('index.html', { root: '.' });
});

app.listen(port, () => console.log(`App listening at http://localhost:${port}`));

thank you

CodePudding user response：

You already have the JSON data (from await userResult.json()) with it you can either get the property from the object or destructure it.

Getting property

const user = await userResult.json();
const username = user.username

Destructuring

const { username, id } = await userResult.json()

You can find out more about what properties you can extract from the Discord documentation
