使用Promise而不是自定义回调的passport.authenticate() [英] passport.authenticate() using a Promise instead of a Custom Callback

问题描述

passport.authenticate()，如何定义 Promise 而不是使用 Custom Ballback ?

passport.authenticate(), how can I define a Promise instead of using a Custom Ballback?

如何使用 passport.authenticate()在此处引用: http://www.passportjs.org/docs/authenticate/

How to used passport.authenticate() is referenced within here: http://www.passportjs.org/docs/authenticate/

在此页面中，有一个部分自定义Ballback :

Within this page, there is a section Custom Ballback:

如果内置选项不足以处理身份验证请求，则可以提供自定义回调以允许应用程序处理成功或失败.

If the built-in options are not sufficient for handling an authentication request, a custom callback can be provided to allow the application to handle success or failure.

app.get('/login', function(req, res, next) {
  passport.authenticate('local', function(err, user, info) {
    if (err) { return next(err); }
    if (!user) { return res.redirect('/login'); }
    req.logIn(user, function(err) {
      if (err) { return next(err); }
      return res.redirect('/users/' + user.username);
    });
  })(req, res, next);
});

自定义回调定义为:

function(err, user, info){...}

我想做的是将这个自定义回调替换为承诺.

What I wish to do is replace this Custom Callback with a Promise.

[Promise](resolve, reject)
.then(res => {
})
.catch(err => {
})

我该怎么做?谢谢.

Thanks all for your helpful responses @sterling-archer and @el-finito

我发现Passport.js Github存储库中的一个相关问题有助于使用Passport处理password.authenticate()回调:使用带有护照的节点来实现"

I had found a related issue within Passport.js Github repository helpful for using Passport to handle passport.authenticate() callback: "Using node's promisify with passport"

export const authenticate = (req, res) =>
  new Promise((resolve, reject) => {
    passport.authenticate(
      [passport strategy],
      { session: false },
      (err, user) => {
        if (err) reject(new Error(err))
        else if (!user) reject(new Error('Not authenticated'))
        resolve(user)
      })(req, res)
    })
