Question

OAuth2正在制作＆＃34;用户名和密码不被接受＆＃34;尝试使用Gmail + Nodejs + Nodemailer发送电子邮件时出错

代码 - Nodejs - Nodemailer和xoauth2

var nodemailer = require("nodemailer");

var generator = require('xoauth2').createXOAuth2Generator({
    user: "", // Your gmail address.

    clientId: "",
    clientSecret: "",
    refreshToken: "",
});



// listen for token updates
// you probably want to store these to a db
generator.on('token', function(token){
    console.log('New token for %s: %s', token.user, token.accessToken);
});


// login
var smtpTransport = nodemailer.createTransport({
    service: 'gmail',
    auth: {
        xoauth2: generator
    }
});


var mailOptions = {
    to: "",
    subject: 'Hello ', // Subject line
    text: 'Hello world ', // plaintext body
    html: '<b>Hello world </b>' // html body
};


smtpTransport.sendMail(mailOptions, function(error, info) {
  if (error) {
    console.log(error);
  } else {
    console.log('Message sent: ' + info.response);
  }
  smtpTransport.close();
});

的问题：

我使用Google OAuth2游乐场创建代币，https://developers.google.com/oauthplayground/
它看起来使用refreshToken获取有效的accessToken，（即它在屏幕上打印新的访问令牌。）在尝试发送电子邮件之前没有错误。
我添加了可选的accessToken：但是得到了同样的错误。（＆＃34;不接受用户名和密码＆＃34;）
我不是100％确定＆＃34;用户名＆＃34;，文档说它需要＆＃34;用户＆＃34;电子邮件地址 - 我想是为令牌创建的帐户的电子邮件，但不是100％清除。我尝试了几件事但都没有用。
我搜索了gmail帐户上的选项，没有发现任何看起来不对的内容。
此外，当我使用Java时，它需要google userID而不是电子邮件地址，不知道为什么这是使用电子邮件地址而Java正在使用UserId。

Answer 1

nodemailer以“compose”范围

失败

问题是“范围”

它失败了： https://www.googleapis.com/auth/gmail.compose

但如果我使用，则可以正常工作 https://mail.google.com/

Answer 2

只需执行以下操作：

1-从此处https://developers.google.com/gmail/api/quickstart/nodejs获取凭据.json文件，按启用Gmail API，然后选择“桌面”应用

2-将此文件与您的凭据文件一起保存

const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');

// If modifying these scopes, delete token.json.
const SCOPES = ['https://mail.google.com'];
// 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.
fs.readFile('credentials.json', (err, content) => {
    if(err){
        return console.log('Error loading client secret file:', err);
    }

    // Authorize the client with credentials, then call the Gmail API.
    authorize(JSON.parse(content), getAuth);
});

/**
 * 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, (err, token) => {
        if(err){
            return getNewToken(oAuth2Client, callback);
        }
        oAuth2Client.setCredentials(JSON.parse(token));
        callback(oAuth2Client);
    });
}

/**
 * Get and store new token after prompting for user authorization, and then
 * execute the given callback with the authorized OAuth2 client.
 * @param {google.auth.OAuth2} oAuth2Client The OAuth2 client to get token for.
 * @param {getEventsCallback} callback The callback for the authorized client.
 */

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);
        });
    });
}

function getAuth(auth){

}

3-通过在您的终端中输入以下文件来运行此文件：节点THIS_FILE.js

4-您将拥有token.json文件

5-从凭据.json和令牌.json获取用户信息，并将其填写到以下函数中

const nodemailer = require('nodemailer');
        const { google } = require("googleapis");
        const OAuth2 = google.auth.OAuth2;

        const email = 'gmail email'
        const clientId = ''
        const clientSecret = ''
        const refresh = ''



        const oauth2Client = new OAuth2(
            clientId,
            clientSecret,
        );

        oauth2Client.setCredentials({
            refresh_token: refresh
        });
        const newAccessToken = oauth2Client.getAccessToken()


        let transporter = nodemailer.createTransport(
            {
                service: 'Gmail',
                auth: {
                    type: 'OAuth2',
                    user: email,
                    clientId: clientId,
                    clientSecret: clientSecret,
                    refreshToken: refresh,
                    accessToken: newAccessToken
                }
            },
            {
                // default message fields

                // sender info
                from: 'Firstname Lastname <your gmail email>'
            }
        );

        const mailOptions = {
            from: email,
            to: "",
            subject: "Node.js Email with Secure OAuth",
            generateTextFromHTML: true,
            html: "<b>test</b>"
        };

        transporter.sendMail(mailOptions, (error, response) => {
            error ? console.log(error) : console.log(response);
            transporter.close();
        });
