从谷歌升级+；登录到Google登录Node.js

我有一个NodeJs Google cloud项目运行良好，我正在使用Google+登录获取用户配置文件，但我收到一条来自Google的消息，称Google+登录已被完全弃用，并将于2019年3月7日关闭。 如果不使用methode

plus.people.get

以下是我的身份验证函数：

module.exports = function(config) {

 var googleapis = require('googleapis');
 var request =    require('request');

 var client = new googleapis.auth.OAuth2(
   config.oauth2.clientID,
   config.oauth2.clientSecret,
   config.oauth2.redirectUrl
 );

 function getAuthenticationUrl() {
   return client.generateAuthUrl({
     access_type: 'offline',
     prompt: 'consent',
     scope: [
       'email',
       'profile',
       'https://www.googleapis.com/auth/spreadsheets',
       'https://www.googleapis.com/auth/gmail.send'
     ]
  });
}

function refreshAccessToken(tokens, callback){
  client.setCredentials(tokens)
  client.refreshAccessToken(function(err, tokens){
    console.log(err)
    client.setCredentials(tokens);
    callback(err, tokens)
  });
}

function getUserStandard(authorizationCode, callback){
  getUser(authorizationCode, client, callback) 
}

function getUser(authorizationCode, client, callback) {
  // With the code returned from OAuth flow, get an access token
  client.getToken(authorizationCode, function(err, tokens) {
    if (err) return callback(err);
    // Configure this Google API client to use the access token
    console.log("------------ getToken ---------------")
    console.log(tokens)
    console.log(tokens.refresh_token)
    client.setCredentials({
      access_token:  tokens.access_token,
      refresh_token: tokens.refresh_token,
      id_token:      tokens.id_token,
      token_type:    tokens.token_type,
      expiry_date:   tokens.expiry_date
    });
    //I bealive that this code here should be changed according to the message recieved from Google.
    // Call the Google+ API to get the profile of the user who authenticated
      googleapis.plus('v1').people.get({ userId: 'me', auth: client },function(err, profile) {
      if (err) return callback(err);
        console.log(profile)
        var user = {
          id:       profile.id,
          name:     profile.displayName,
          imageUrl: profile.image.url,
          email:    profile.emails[0].value,
          tokens:   tokens
       };
       callback(null, user);
    });
  });
}


return {
  getAuthenticationUrl: getAuthenticationUrl,
  getUserStandard:      getUserStandard,
  refreshAccessToken:   refreshAccessToken
};
};

更新：我根据谷歌文档做了一些更改

身份验证工作正常，但在调用登录回调时，我无法将用户信息存储到会话中。我将用户存储在会话中，但当用户重定向到原始url时，我将丢失存储的信息

app.js:

app.get('/', function (req, res, next) {

req.session.url = "/";

console.log("********************* Default ***********************")
console.log(req.user)

if (!req.session.user){
    console.log("------------ No session ------------") 
    authRequired(req, res, next);
}else{

    var languageInfo = util.getLanguageJSON(req);
    var languageJSON = languageInfo[0];
    var LanguageName = languageInfo[1];

我的代码有问题吗
