当我创建 passport-saml 策略时，在登录期间，有一个配置文件对象传递给中间件函数，其中包含 nameID 信息。我需要该信息以稍后调用注销。

// passportHandler.js
const passport = require("passport");
const passportSaml = require("passport-saml");

passport.serializeUser((user, done) => {
  done(null, user);
});

passport.deserializeUser((user, done) => {
  done(null, user);
});

// SAML strategy for passport -- Single IPD
const samlStrategy = new passportSaml.Strategy(
  {
    entryPoint: process.env.SSO_ENTRYPOINT,
    logoutUrl: process.env.SSO_LOGOUT,
    issuer: process.env.SSO_ISSUER,
    callbackUrl: process.env.SSO_CALLBACK_URL || undefined,
    path: process.env.path,
    cert: process.env.SSO_CERT.replace(/\\n/gm, "\n"), // change "\n" into real line break
  },
  (profile, done) => {
    console.log('profile', profile);  // nameID and nameIDFormat are in profile object
    done(null, profile)
  }
);

passport.use(samlStrategy);

module.exports = passport;

index.js

// index.js of Express server
import passport from "./src/passportHandler";
import { getLogout } from "./src/routes.js";
const app = express();
app.use(passport.initialize());
app.use(passport.session());
app.get('/sso/logout', getLogout); // this route, I need the above 2 data

getLogout 函数从另一个文件导入，我硬编码，我nameID如何nameIDFormat从开始的profile对象中获取它们，将它们保存在某个地方，并将它们传递给这个路由？

// routes.js
export const getLogout = (req, res) => {
  !req.user && (req.user = {})
  req.user.nameID = 'Eric1234@outlook.onmicrosoft.com'; // hardcode, how to pass this info?
  req.user.nameIDFormat = 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress'; // hardcode too
  const samlStrategy = req._passport?.instance?._strategies?.saml;  // is this correct?
  samlStrategy.logout(req, (err, request) => {
    if (!err) {
      res.redirect(request);
    }
  })
};

我的第二个问题是，我从中获取 samlStrategy 对象req._passport?.instance?._strategies?.saml，这是获取它的正确方法吗？或者，同样的问题，我怎样才能从一开始就将 saml strategy obj 传递给这条路线？

谢谢你的帮助！

回答我自己的愚蠢问题...

在 samlStrategy 中，最后调用done(null, profile)

const samlStrategy = new passportSaml.Strategy(
  {
    entryPoint: process.env.SSO_ENTRYPOINT,
    logoutUrl: process.env.SSO_LOGOUT,
    issuer: process.env.SSO_ISSUER,
    callbackUrl: process.env.SSO_CALLBACK_URL || undefined,
    path: process.env.path,
    cert: process.env.SSO_CERT.replace(/\\n/gm, "\n"), // change "\n" into real line break
  },
  (profile, done) => {
    console.log('profile', profile);  // nameID and nameIDFormat are in profile object
    done(null, profile)
  }
);

那么该profile对象将成为req.userService Provider的Login Post Callback函数中的对象

logout然后我可以将用户对象保存在某个地方，并在被调用时再次使用它。
