Question

我无法远程发送电子邮件。我不知道发生了什么。

function getNewToken(oAuth2Client, callback) {
    const authUrl = oAuth2Client.generateAuthUrl({
        access_type: 'offline',
        scope: SCOPES,
    });
    console.log('Authorize this app by visiting this url:', authUrl);
    const rl = readline.createInterface({
        input: process.stdin,
        output: process.stdout,
    });
    rl.question('Enter the code from that page here: ', (code) => {
        rl.close();
        oAuth2Client.getToken(code, (err, token) => {
            if (err) return console.error('Error retrieving access token', err);
            oAuth2Client.setCredentials(token);
            // Store the token to disk for later program executions
            fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
                if (err) return console.error(err);
                console.log('Token stored to', TOKEN_PATH);
            });
            callback(oAuth2Client);
        });
    });
}

// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/gmail.readonly'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';

// Load client secrets from a local file.
function customMethod() {
    fs.readFile('credentials.json', (err, content) => {
        if (err) return console.log('Error loading client secret file:', err);
        // Authorize a client with credentials, then call the Gmail API.
        authorize(JSON.parse(content), callbackAuthorize);
    });
}

/**
 * Create an OAuth2 client with the given credentials, and then execute the
 * given callback function.
 * @param {Object} credentials The authorization client credentials.
 * @param {function} callback The callback to call with the authorized client.
 */
function authorize(credentials, callback) {
    const { client_secret, client_id, redirect_uris } = credentials.installed;
    const oAuth2Client = new google.auth.OAuth2(client_id, client_secret, redirect_uris[0]);
    // Check if we have previously stored a token.
    fs.readFile(TOKEN_PATH, async (err, token) => {
        if (err) return getNewToken(oAuth2Client, callback);
        oAuth2Client.setCredentials(JSON.parse(token));
        callback(oAuth2Client);
    });
};

function callbackAuthorize(newCredentials) {
    transporter = nodemailer.createTransport(smtpTransport({
        service: "Gmail",
        logger: true,
        auth: {
            type: 'OAuth2',
            user: process.env.email,
            pass: process.env.passMail,
            clientId: process.env.CLIENT_ID,
            clientSecret: process.env.CLIENT_SECRET,
            accessToken: newCredentials.credentials.access_token,
            refreshToken: newCredentials.credentials.refresh_token
        },
    }));
    transporter.verify(function (error, success) {
        if(error) console.log(error);
    })
};

let transporter = nodemailer.createTransport({
    service: 'Gmail'
})

transporter.verify(function (error, success) {
    fs.readFile('credentials.json', (err, content) => {
        if (err) return console.log('Error loading client secret file:', err);
        // Authorize a client with credentials, then call the Gmail API.
        authorize(JSON.parse(content), callbackAuthorize);
    });
});

我正在使用Nodemailer和Gmail API生成新令牌，但是在Heroku上不起作用。当我在本地发送电子邮件时：

当我在Heroku上发送电子邮件时：

如果我访问以下链接：https://accounts.google.com/b/0/DisplayUnlockCaptcha，它会起作用一段时间，但是我想自动执行此操作。我该怎么办？

我无法远程发送电子邮件。我该如何解决？
