Passport单选按钮重定向到注册页面

Question

If the user has the 'No' radio option button selected, how do I redirect to /signup?

ROUTE

// app/routes/users.js

app.post('/users/session', passport.authenticate('local', {
    failureRedirect: '/signin',
    failureFlash: true
}), users.session);

VIEW

<form action="/users/session" method="post">
  <input ng-change="change()" ng-model="NotSureWhatToPutHere" type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked> 
    <label for="optionsRadios1">
      No, I am a <b>new customer</b>.
    </label>
  <input type="radio" ng-model="NotSureWhatToPutHere" ng-change="change()" name="optionsRadios" id="optionsRadios2" value="option2">
    <label class="control-label" for="optionsRadios2">
    Yes, I have a password:
    </label>
  <button type="submit">Sign in</button>   
</form>

CONTROLLER

// controllers/index.js

'use strict';

angular.module('mean.system').controller('IndexController', ['$scope', 'Global', function ($scope, Global) {
    $scope.global = Global;
}]);

This is not so much node/passport issue, it's an angular one.

I guess that you submit this with either angular (like, $http.post('/users/session',...) or you have a <form action='/users/session' ...> .

You need to tell angular that listens for the radio buttons (like, ng-change or something similar). When the user switches between no password and password, you should change your url to /signup.

So, no need to hit the server at all there. If you do want to proceed, you could add another middleware in there? Something like:

app.post('/users/session', function(req, res, next) { if (req.body.youroptionselected) return res.redirect('/somewhere'); next(); }, .... other handler here) .

This would not redirect to POST /signup though - redirects never do.

Your Angular controller (client-side) example would be something like this:

angular.service('loginService', function($http){
    var service = {
        signin: function(email, password){
            $http.post('/users/session', {email: email, password: password})
            .success(function(response){
                // You're logged in here, you could do something like a redirect.
            })
            .catch(function(err){
                console.log('Something wen\'t wrong, show this message or something.');
            });
        }
        , signup: function(email) {
            $http.post('/signup', {email: email})
            .success(function(response){
                // You've handled this in your backend, now on the client you're in.
            })
            .catch(function(err){
                console.log('Something wen\'t wrong with signup., show this message or something.');
            });
        }
    }
})

angular.controller('loginController', function(loginService){
    // get a hold of the button here
    $scope.buttonClickHandler = function(){
        // if new user, use loginService.signup($scope.email)...
        // else use loginService.signin($scope.email, $scope.password) ...
    }
})
