使用passport获取错误“没有在name: local下注册策略”

Question

我在用火车头，试图用护照。尽管如此，我还是弄明白了require函数，因为各种指南并不是特别清楚我需要什么才能让程序运行。以下是我的routes.js：

// MVC routes can be mapped mapped to controllers using convenient
// `controller#action` shorthand.  Standard middleware in the form of
// `function(req, res, next)` is also fully supported.  Consult the Locomotive
// Guide on [routing](http://locomotivejs.org/guide/routing.html) for additional
// information.
//
passport = require('/usr/local/lib/node_modules/passport');
passport_local = require('/usr/local/lib/node_modules/passport-local');

module.exports = function routes() {
this.root('pages#main');
this.match('login', passport.authenticate('local', { successRedirect: '/',
                                                     failureRedirect: '/login' }))
}

它会显示以下错误消息：

Express
500 Error: no strategy registered under name: local

谢谢你的帮助

Answer 1

据我所知，您首先需要使用github page中列出的passport.use向passport注册本地策略。

Answer 2

您将需要使用：

passport.use(new LocalStrategy(function(username, password, done) {
 ...
}));

来注册策略。如果您将其放入pass.js这样的文件中，则需要将其包含在启动文件中：

var pass = require('./pass');

当我忘记将它包含在我的app.js文件中时，我遇到了同样的问题。虽然你不会在你的启动文件中显式地调用'pass‘，但passport会在初始化时使用它。

Answer 3

确保在本地库中安装了本地策略。Npm安装passport-local
