我一直在遵循Firebase团队针对Instagram HERE

进行的类似教程工作，从而致力于Spotify的oauth2流程

我能够提交我的凭据，并在url中返回用户代码和状态，但是当我运行方法以提交代码以返回auth令牌时，我打印到Firebase函数中控制台的auth令牌将返回：Auth Token Error Not Found。这是我的工作流程：

首先，我有一个功能来配置我的spotifyOAuth：

function spotifyOAuth2Client() {
    // Spotify OAuth 2 setup
    const credentials = {
        client: {
            id: functions.config().spotify.clientid,
            secret: functions.config().spotify.clientsecret,
        },
        auth: {
            tokenHost: 'https://accounts.spotify.com',
            authorizePath: '/authorize'
        },
    };
    return require('simple-oauth2').create(credentials);
}

我在使用https://us-central1-<my project string>.cloudfunctions.net/redirect调用的Firebase函数中使用该函数：

exports.redirect = functions.https.onRequest((req, res) => {
    const oauth2 = spotifyOAuth2Client();

    cookieParser()(req, res, () => {
        const state = req.cookies.state || crypto.randomBytes(20).toString('hex');
        console.log('Setting verification state:', state);
        res.cookie('state', state.toString(), {
            maxAge: 3600000,
            secure: true,
            httpOnly: true,
        });
        const redirectUri = oauth2.authorizationCode.authorizeURL({
            redirect_uri: OAUTH_REDIRECT_URI,
            //scope: OAUTH_SCOPES,
            state: state,
        });
        console.log('Redirecting to:', redirectUri);
        res.redirect(redirectUri);
    });
});

上面的代码返回带有适当参数的url字符串，下面的代码块是我的代码中断的地方，我还有另一个从上面的res.redirect(redirectUri)重定向后运行的cloud函数。当我尝试运行getToken()方法时，它似乎未返回任何内容，因为我撞到了catch块？我在这里观察Auth Token Error Not Found。

const oauth2 = spotifyOAuth2Client();

    try {
        return cookieParser()(req, res, async () => {
            console.log('Received verification state:', req.cookies.state);
            console.log('Received state:', req.query.state);
            if (!req.cookies.state) {
                throw new Error('State cookie not set or expired. Maybe you took too long to authorize. Please try again.');
            } else if (req.cookies.state !== req.query.state) {
                throw new Error('State validation failed');
            }
            console.log('Received auth code:', req.query.code);
            console.log(OAUTH_REDIRECT_URI);

            // Get the access token object (the authorization code is given from the previous step).
            const tokenConfig = {
                code: req.query.code,
                redirect_uri: 'http://localhost:8100/popup'
            };

            // Save the access token
            try {
                const result = await oauth2.authorizationCode.getToken(tokenConfig)
                const accessToken = oauth2.accessToken.create(result);
                console.log('inside try');
                console.log(result);
                console.log(accessToken);
            } catch (error) {
                console.log('Access Token Error', error.message);
            }

我已经在配置中仔细检查了我的Spotify客户端/秘密凭据，此OAuth2流出了什么问题？

解决了我的问题，我没有使用正确的端点：

const credentials = {
    client: {
        id: functions.config().spotify.clientid,
        secret: functions.config().spotify.clientsecret,
    },
    auth: {
        tokenHost: 'https://accounts.spotify.com',
        authorizePath: '/authorize',
        tokenPath: '/api/token'
    },
};

OAuth2无法使用simple-oauth2和Firebase函数进行Spotify身份验证返回身份验证令牌
