我怎样才能将jwt令牌从后端nodejs传递到前端angularjs

Question

我创建了一个jwt令牌并存储在数据库中。当登录成功完成后，我想用令牌重定向到主页。我怎么能这样做。

我的Nodejs文件。

app.post('/authenticate', function(req, res, next) {
    User.findOne({name: req.body.name}, function(err, user) {

        if (err) {throw err;}

        if (!user) {
          res.json({ success: false, message: 'Authentication failed. User not found.' });
        } else if (user) {

          // check if password matches
          if (user.password !==  req.body.password) {
            res.json({ success: false, message: 'Authentication failed. Wrong password.' });
          } else {

            // if user is found and password is right
            // create a token
            var token = jwt.sign(user, app.get('superSecret'), {
              expiresIn: 1440 // expires in 24 hours
            });

            // return the information including token as JSON
            res.json({
              success: true,
              message: 'Enjoy your token!',
              token: token
            });
          }   

        }

      });
    });

我的angularjs文件

var app = angular.module('loginApp', []);
  // Controller function and passing $http service and $scope var.
  app.controller('loginCtrl', function($scope, $http) {
    // create a blank object to handle form data.
    $scope.user = {};
    // calling our submit function.
    $scope.submitForm = function() {
      // Posting data to  file
      $http.post('/tokken/login/', $scope.user).then(function (response) {
          //$http.defaults.headers.common['Token'] = token
        if (response.errors) {
          // Showing errors.
          $scope.errorName = response.errors.name;
          $scope.erroPassword = response.errors.password;
        } else {
          $scope.message = response.data;
        }
      });
    };
  });

我在相同的登录页面中打印令牌值。我想使用令牌

重定向到另一个页面
