编辑:抱歉这么久了，在编译好的JS中添加!我还添加了 Kevs 建议。

我正在开发一个 MEAN 堆栈应用程序(MongoDB、ExpressJS、Angular、NodeJS)并且玩得很开心，尤其是使用 CoffeeScript 。我的问题是我无法让 passport.js 工作，每次它返回 {success: false}。当我在 LocalStrategy 函数中执行 console.log 时，它似乎从未被调用过。知道为什么吗？

一些片段

server.coffee(主文件)

...
Account = mongoose.model 'account'

passport.use 'local-login', new LocalStrategy (_username, password, done) ->
  Account.findOne {username:_username}, (error, user) ->
    if error
      done error
    if not user
      done null, false, {message:'Incorrect username.'}
    done null,user
passport.serializeUser (user, done) ->
  console.log 'serialize user'
  if user
    done null, user
passport.deserializeUser (id, done) ->
  Account.findOne({_id:id}).exec (error, user) ->
    if user
      return done null, user
    else
      return done null, false
...

Account = mongoose.model('account');

    return Account.findOne({
      username: _username

      if (error) {
        done(error);
      }
      if (!user) {
        done(null, false, {
          message: 'Incorrect username.'
        });
      }
      return done(null, user);
    });
  }));

  passport.serializeUser(function(user, done) {
    console.log('serialize user');
    if (user) {
      return done(null, user);
    }
  });

  passport.deserializeUser(function(id, done) {
    return Account.findOne({
      _id: id
    }).exec(function(error, user) {
      if (user) {
        return done(null, user);

我的 Angular 登录 Controller

app.controller 'loginCtrl', ['$scope', '$http', ($scope, $http) ->
  $scope.login = (username, password) -> 
    $http.post('/login', {username: username, password: password}).then (response) ->
      console.log response.data
      if response.data.success
        console.log "Logged in as #{username}"
      else
        console.log "Failed to login as #{username}"
]

编译好的js

  app.controller('loginCtrl', [
    '$scope', '$http', function($scope, $http) {
      return $scope.login = function(username, password) {
        return $http.post('/login', {
          username: username,
          password: password
        }).then(function(response) {
          console.log(response.data);
          if (response.data.success) {
            return console.log("Logged in as " + username);
          } else {
            return console.log("Failed to login as " + username);
          }
        });
      };
    }
  ]);

和我的登录表单(jade):

h3 Login
  form(ng-controller="loginCtrl")
    .row
      .columns.small-12.large-12
        form
          label Username
          input(placeholder="username",name="username",type="text",ng-model="username")
          label Password
          input(placeholder="password",name="password",type="password",no-model="password")
          div(align="center")
            button.button(ng-click="login(username,password)") Login
            span  
            a.button(href="/user/Register") Register

示例用户创建良好，所以 mongoose 没问题，并且在我开始使用 Passport 之前就已经设置好了。我学习了几个不同的教程，这让我发疯了!

最佳答案

例如，您没有设置 passport.use 的初始参数并将请求传回回调 - 来 self 的代码:

passport.use('local-login', new LocalStrategy({
    // by default, local strategy uses username and password, we will override with email
    usernameField : 'email',
    passwordField : 'password',
    passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) {

    // asynchronous
    // User.findOne wont fire unless data is sent back
    process.nextTick(function() {

      db.Account.findOne( { ...

然后您可以使用以下方式进行身份验证:

passport.authenticate('local-login',function(err,user,info){

在您的情况下，您正在调用 passport.authenticate 'local' 因此 passport.use 中的第一个参数应该是 'local' 以便它调用正确的策略

关于javascript - 只是无法让 Passport.js 工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23569317/
