刷新Passportjs中的JWT令牌

Question

我使用的是passport-openidconnect策略，这个策略运行良好，但是会话过期时间只有3600秒，我认为它是不可更改的。

如果我要获取另一个令牌ID，该如何使用刷新令牌？

如果要这样做，在类似下面这样的东西中，我应该在哪里添加逻辑？ https://github.com/passport/express-4.x-openidconnect-example/blob/master/server.js

会话过期时间可在认证提供者端进行配置。例如，假设您正在使用auth0作为身份验证提供者，则可以在应用程序设置（https://auth0.com/docs/tokens/guides/access-token/set-access-token-lifetime）中配置token超时时间。

就“刷新令牌（refresh token）”而言，Passport本身不支持，我们需要自己实现。对于Auth0，您可以按照https://auth0.com/docs/tokens/refresh-token/current中的流程来更新令牌。我从该链接中复制了代码。

var request = require("request");

var options = { method: 'POST',
  url: 'https://YOUR_DOMAIN/oauth/token',
  headers: { 'content-type': 'application/x-www-form-urlencoded' },
  form: 
   { grant_type: 'refresh_token',
     client_id: 'YOUR_CLIENT_ID',
     client_secret: 'YOUR_CLIENT_SECRET',
     refresh_token: 'YOUR_REFRESH_TOKEN' } };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

或者您可以使用一个附加组件来处理护照https://github.com/fiznool/passport-oauth2-refresh

var passport = require('passport'),
  , refresh = require('passport-oauth2-refresh')
  , FacebookStrategy = require('passport-facebook').Strategy;

var strategy = new FacebookStrategy({
  clientID: FACEBOOK_APP_ID,
  clientSecret: FACEBOOK_APP_SECRET,
  callbackURL: "http://www.example.com/auth/facebook/callback"
},
function(accessToken, refreshToken, profile, done) {
  // Make sure you store the refreshToken somewhere!
  User.findOrCreate(..., function(err, user) {
    if (err) { return done(err); }
    done(null, user);
  });
});

passport.use(strategy);
refresh.use(strategy);

var refresh = require('passport-oauth2-refresh');
refresh.requestNewAccessToken('facebook', 'some_refresh_token', function(err, accessToken, refreshToken) {
  // You have a new access token, store it in the user object,
  // or use it to make a new request.
  // `refreshToken` may or may not exist, depending on the strategy you are using.
  // You probably don't need it anyway, as according to the OAuth 2.0 spec,
  // it should be the same as the initial refresh token.
