如何在使用passport进行身份验证时获取twitter返回url

const passport = require('passport');
const TwitterStrategy = require('passport-twitter').Strategy;

passport.use(new TwitterStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET,
    callbackURL: "http://your-app-url/auth/twitter/callback"
  },
  function(token, tokenSecret, profile, done) {
    // 处理验证成功后的逻辑
    // 可以在这里获取用户信息等
  }
));

app.get('/auth/twitter', passport.authenticate('twitter'));

app.get('/auth/twitter/callback',
  passport.authenticate('twitter', { failureRedirect: '/login' }),
  function(req, res) {
    // 获取Twitter返回的URL
    const twitterReturnURL = req.query.oauth_token;
    // 处理验证成功后的逻辑
    res.redirect('/dashboard');
  });
