I have been driving myself crazy. Hoping one of you can help me out here...
Let me give you some background:
I have an ASP.NET web app that uses AngularJS.
Here is what my Controller looks like:
public ActionResult Index()
{
return View();
}
Ultimately this loads my HomePage and everything comes up great. However when I click a link for example:
<a ui-sref="core.applications">My Apps</a>
It prompts me to enter in a Username and Password. Even though this should be set for anonymous access.
Now if I open a new tab and go directly to that page for example: http://localhost/#/core/applications this loads just fine.
Looking at my routes:
app.config(function ($stateProvider, $urlRouterProvider, $httpProvider) {
$urlRouterProvider.otherwise('/core/dashboard');
$stateProvider
.state('core', {
url: '/core',
views: {
'': { templateUrl: 'app/core/views/core.html' },
'sidebar#core': {
templateUrl: 'app/core/views/sidebar.html'
},
'content#core': {
templateUrl: ''
}
}
})
.state('core.dashboard', {
url: '/dashboard',
views: {
'content#core': {
templateUrl: 'app/core/views/dashboard.html'
}
}
})
.state('core.applications', {
url: '/applications',
views: {
'content#core': {
templateUrl: 'app/core/views/applications.html'
}
}
})
});
I do not see what could be blocking it and prompting it to load a Username and Password. Is it something to do with ASP.NET Routing? Please help!
I actually figured out the issue.
The issue was related to the Web API call that I do that I pass security credentials and if the credentials end up being repeated too quickly my system blocks them... (dumb enterprise security guys)
Long story short - check if you are calling a 3rd party service this could prevent you from accessing those pages.

I am new to angular js, and I am creating admin panel with angular js but I have issue as follows:
$stateProvider
.state('app', {
url: '',
templateUrl: 'menu/menu.html',
controller: 'menuCntrl',
abstract: true,
authenticate: true
})
.state('dashboard', {
url: "/",
templateUrl: 'dashboard/dashboard.html',
controller: 'DashboardCtrl',
parent: "app",
authenticate: true
})
.state('login', {
url: "/login",
templateUrl: 'dashboard/test.html',
controller: 'LoginCtrl',
authenticate: false
})
$urlRouterProvider.otherwise("/");
this is my current routing now my issue is I need to handle login and registration with it. as like if user is logged in then only user can see the dashboard but I can't understand how to handle it.
$rootScope.$on("$stateChangeStart", function (event, toState, toParams, fromState, fromParams) {
if (toState.authenticate ) {
$state.go("/");
event.preventDefault();
}else{
$state.go("/login");
}
})
this is also I have tried but not worked and also I need to handle registration as well...
can anyone help to figure out what will be best method to handle login and registration before user will redirect to dashboard.
Thanks in advance :)
You need to store some value in localstorage or cookies or session to save user is login or not.
Create a function to check user is loged in or not.
In menu controller check if user is login then fine other wise redirect on login page.
Same in your app config.
if user is login then use this:
$urlRouterProvider.otherwise("/");
other wise if user is not login then use this:
$urlRouterProvider.otherwise("/login");
I am using AngularJS in a nodewebkit application.
I have three views:
Home.html
Conversation.html
Login.html
On login, I am calling
$state.go('home.main');
which calls
$stateProvider.state('home.main', {
url: '/home',
views: {
"mainContent": {
templateUrl: 'views/home.html',
controller: 'loginController'
}
}
}
In main html, I am making a server call (through socket.io) to get all conversations.
Since data is huge, it takes some time to load it and in this time gap i.e. before user gets response from server, If user clicks on Logout, It takes user back to login page.
$scope.logout = function(){
//Logout Logic
$state.go('login');
}
i.e. it calls
$stateProvider.state('login', {
url: '/login',
templateUrl: 'views/login.html',
controller: "loginController"
});
Now When a user is trying to login, server responds to call made for getting conversations allowing user to take him to /home/conv.html.
I don't want to disable Logout button while data is being sent from server to client.
Is there any way on routing from /home to /login, we can cancel all server calls?
I copied the code from https://github.com/angular-ui/ui-router/wiki:
$stateProvider.state("contacts", {
template: '<h1>{{title}}</h1>',
resolve: { title: 'My Contacts' },
controller: function($scope, title){
$scope.title = 'My Contacts';
},
onEnter: function(title){
if(title){ ... do something ... }
},
onExit: function(title){
if(title){ ... do something ... }
}
})
The onExit event will be triggered when you move from home.main to another route. So you should register to handle the event at where you declare the home.main route. In this event, you can cancel all server calls. As you are using socket.io, I suggest you use the function socket.removeAllListeners();
I have an <ng-view></ng-view> that is filled with a partial html file when a button is clicked i.e Sign In
myApp.js
var myApp = angular.module("myApp", ['ngRoute']);
//Define Routing for app
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/signin', {
templateUrl: 'signin.ejs'
}).
when('/signup', {
templateUrl: 'signup.ejs'
}).
when('/myAccount', {
templateUrl: 'myAccount.ejs'
}).
otherwise({
//home page
});
}]);
What I want to know is, how can fill this ng-view based on data that is sent by the server. For example, if the server renders the index.html with data {page: '/signin'} how can I let Angular know that I want to to populate the ng-view with 'signin.ejs'??
Any help is appreciated. Thank you!!
EDIT:
I have someone logged in to the site and on a page I provide a "switch account" button. So what I want to do is, when that is clicked, post to the server /logout route so the session can be cleared, and then change the page to the signin page (partial html file) and populate the username field with the account that they are switching to
Your ejs needs to be rendered by nodejs so you need to apply your the routing there.
You need to come up with a way to identify the route path like '/partials/:filename'
app.route('/partials/:filename').get(funcs.partials);
Then you handle the request and render your ejs or plain you just send(html) and you use the path module to locate and manipulate the url string.
exports.partials = function(req, res, next, filename) {
res.render(filename, vars);
};
Then your angular is like, though signin is probably not the best example.
$routeProvider.
when('/signin', {
templateUrl: '/partials/signin'
})
I am stuck with this strange behaviour. None of the Google hits seem to return any mention of a similar case so I am assuming that I am doing something seriously wrong.
My interceptor does react on the 401 status and redirects to the appropriate route but at the same time it renders the previous route too. So I have a very ugly flash of one template then the other. I am simply trying to test my authentication: if authenticated then render the table, otherwise render the login form. It does redirect to the login form but still flashes the table template for a fraction of a second.
angular.module('Basal', ['ngRoute', 'Basal.users'])
.config(function($routeProvider, $locationProvider, $httpProvider) {
$locationProvider.html5Mode(true);
$httpProvider.interceptors.push('authInterceptor');
$routeProvider.
when('/', {
templateUrl: '/tpl/table.html',
controller: 'MainCtrl'
}).
when('/login', {
templateUrl: '/tpl/login-form.html',
controller: 'MainCtrl'
}).
otherwise({
redirectTo: '/'
});
});
angular.module('Basal.users', [])
.controller('MainCtrl', function($scope, getJson) {
getJson.fetch(function (d){
$scope.computers = d;
});
})
.factory('getJson', function($http, $location) {
return {
fetch: function (c) {
$http.get("/json")
.success(function(data) {
console.log("getJson: Success!");
c(data);
})
.error(function() {
console.log("getJson: Failure!");
});
}
}
})
.factory('authInterceptor', function($q, $location) {
return {
'responseError': function(response) {
if (response.status === 401) {
$location.path('/login');
}
return $q.reject(response);
}
}
});
Now, when I hit '/' on the browser Angular does two requests on the background: one is to fetch the table template and insert it in to the view and the other is to get the JSON data.
On the server side I put session restriction only on the data request! The template is just a static file. To put restriction on the template I need to drag it through the server routing and this is not, I believe, how Angular does things. But if I do create server side route for the template and put session restriction on it then double rendering disappears.
I am confused about how this works. Fetching the template and fetching the data is done asynchronously in parallel. So while JSON request triggers 401 and redirects to the login template, the original table template is still going through and being rendered empty. Hence I get all the ugly double rendering. This is a race of some kind. How do I stop it? Maybe my interceptor is wrong? Isn't the Angular interceptor supposed to stop any further processing?
As a related issue, the otherwise function on the $routeProvider does not work either. If I put a non-existent URL, I get 404 from the server but Angular routing does not catch it. Is this how it is supposed to be? If a URL change happens in Angular and then I hit reload on the browser, I get an ugly 404 instead of a nice redirect. Am I supposed to handle 404 in an interceptor too? Then what is the point of otherwise?
Thanks.
I am at a total loss with what's wrong with how I've setup my nested views. What am I doing wrong???
app.config(function ($stateProvider, $urlRouterProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$stateProvider
.state('main', {
url: '/',
template: '<div><h1>Hello World</h1><div ui-view></div></div>',
controller: 'MainCtrl'
})
.state('main.test', {
template: '<div><h2>I\'m here!</h2></div>',
url: '/here'
});
});
What happens is I go to / and it shows me "Hello World", and then I go to /here and it shows me a blank page. I'm not sure what I'm doing wrong...
You need to omit the preceding / in url:
.state('main.test', {
template: '<div><h2>I\'m here!</h2></div>',
url: 'here'
});
debugging
when clicking on this anchor ui-router navigates to this location: http://localhost:8000//here
<a ui-sref="main.test">test</a>
In your application you can easily check the url of a state
app.run(function($state){
var href = $state.href('main.test');
console.log(href); # '//here'
});
Be sure to set the server to support html5mode
$location documantation
Server side
Using this mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your
application (e.g. index.html)
