Did you try adding

It's a bit late already but try with:
delete $http.defaults.headers.common.Authorization;
It works for me.

Angular HTTP Basic Auth logout header change ignored

I'm using basic HTTP auth (without SSL for testing).
The login works fine, we send an $http request with the authorization header and if the login is correct, it works.
For logout, I'm setting the Authorization header to a bad value and sending an $http request to "trick" the server. The server seems to ignore the new changed auth header. I verified with developer tools in FF that the header value is all ones, but the request is still successful.
How do I "logout"? The logout function sends a bad Authorization header, and the browser sends it according to firebug. What's going on? This is a Java EE 7 app with Wildfly 9 and Shiro, if that makes a difference.
Here is the code:
var DataFactory = function($http, $rootScope, $base64, $cookieStore) {
var _debug = false;
function _d(message) {
if (!_debug) {
return;
}
console.log(message);
}
function setDebug(flag) {
_debug = flag;
}
function doLogout() {
_d("Logging out");
$rootScope.globals = {};
$cookieStore.remove('globals');
$http.defaults.headers.common['Authorization'] = 'Basic 111111111111111111';
$http.get(
'http://localhost:8080/myapp/rest/v1/svc')
.then(function(data) {
alert("Logout: " + JSON.stringify(data.data));
}, function(data) {
alert("Logout Error: " + JSON.stringify(data))
});
}
function doLogin(username, password) {
var token = $base64.encode(username + ":" + password);
_d("Logging " + username + " in with token " + token);
$http.defaults.headers.common['Authorization'] = 'Basic ' + token; // jshint
// ignore:line
$rootScope.globals = {
token : token,
username : username
};
$cookieStore.put("globals", $rootScope.globals);
_d("Login finished, globals are: " + JSON.stringify($rootScope.globals));
$http.get(
'http://localhost:8080/myapp/rest/v1/svc')
.then(function(data) {
alert(JSON.stringify(data.data));
}, function(data) {
alert("Error: " + JSON.stringify(data))
});
}
;
return {
setDebug : setDebug,
doLogin : doLogin,
doLogout : doLogout
};
}
Sending your own authorization string within a XHR request will not magically delete the information cached in the browser. Basic authentication has no concept of logging out. The only way to "logout" with basic authentication is to make the credentials invalid at the server, i.e. change username and/or password so that the stored credentials do not work any longer.

How to get user.email in server using auth0 and node.js?

On my frontend, I can see the email through:
console.log(auth.profile.email)
Then I call this service to retrieve some information from the backend, it's protected so you need to be logged in to get anything back:
var metadata_req = {
method: "GET",
url: "http://localhost:80/protected/all/metadata"
}
On the backend, I'm using node.js and this to verify that the user is logged in before doing a request:
var jwtCheck = express-jwt({
secret: new Buffer(config.secret, 'base64'),
audience: config.client_id
});
But if I print out req.user, I only see iss, sub, aud, exp and iat. I would like to see the email as well.
You can get profile information in req.user by including the email permission when your user initially logs in.
For example, using lock in angular would look like this:
auth.signin({
authParams: {
scope: 'openid email'
}
}, function(profile, token) {
// stuff
}, function(err) {
// error handling
});
Change your API definition from "all/metadata" to "all/metadata/:emailId"
Call your API
var metadata_req = {
method: "GET",
url: "http://localhost:80/protected/all/metadata/{your_email_id}"
}
In NodeJS retrieve you email_id from req.params.emailId

How to display logon page and get user name and password from Angular?

In my angular controller, I have the following code to check if logon is required:
$scope.checkApi = "api/check";
$http.post($scope.checkApi).then(function (response)
{
if (response.status != 200)
{
alert("Logon required.");
}
}, function (response)
{
if (response.status != 200)
{
alert("Logon required.");
}
});
If logon is required, then from the controller I want to display the logon page to get user name and password, then use the user name and password to access the web API like this:
var userCredential = btoa(userName + ":" + password");
$http.get(usersApi, { headers: { "Authorization": "Basic " + userCredential } }).then(function (response)
{
});
Thanks.
You can redirect to login page instead to giving alert. Use $window.location.href= url mapping for login page;

How to clear cookies in angularjs?

i am using a web service having basic authentication i.e. below code shows how i calling the web service
var url='http:url.com/;
$http.defaults.headers.common['Authorization'] = 'Basic ' + Base64.encode(Username + ':' + password);
$http({method: 'GET', url: url}).
success(function(data) {
if(data=='' || data==null || data=='undefined'){
var alertPopup = $ionicPopup.alert({
title: 'Info!',
template: 'Invalid Password, or no user found with this Email Address'
});
alertPopup.then(function(res) {
console.log('Invalid Password, or no user found with this Email Address ');
});
return false;
}
else{
var favoriteCookie = $cookies['JSESSIONID'];
window.localStorage['data'] = JSON.stringify(data);
//console.log("LOGIvar: " + data+ " - PW: " + password);
console.log(data);
$state.go('app.tasklists');
return false;
}
}).
i am getting the correct response and all working fine.
But when i logout the app i am using the below code
$cookieStore.remove('JSESSIONID');
$cookieStore.remove('JSESSIONIDSSO');
$http.defaults.headers.common['Authorization']='undefind';
$scope.modal.show();
$state.go('login',{}, {reload: true});
the real problem is when i logedout then try to logged in with incorrect password it getting logged in web service retuning the previous user details.how can i fix this one thanks in advance?
Just to answer your question:
remove cookies and header, then it asks for re-authentication and also clear native application then it is working fine

How to remove basic authentication in angularness?

Hi am using basic authentication for webservie integration.
$http.defaults.headers.common['Authorization'] = 'Basic ' + Base64.encode(Username + ':' + password);
$http({method: 'GET', url: 'http:url.com'}).
success(function(data) {
if(data=='' || data==null || data=='undefined'){

title: 'Info!',
template: 'Invalid Password, or no user found with this Email Address'
});
alertPopup.then(function(res) {
console.log('Invalid Password, or no user found with this Email Address ');
});
}
This code is working fine for me .but my problem is if one user is logedin using username and password.then logged out after that another user try to logged in with different username and password will get the previous user loged in. how to clear the header authentication data?
You could probably redefine the header with
$http.defaults.headers.common['Authorization'] = 'Basic ' + Base64.encode(newUsername + ':' + newPassword)
It seems that,
You have not replaced the Authorization header when
the user logged out
logged in as a different user
Login - call this every time a user logs in
function setCredentials(username, password) {
$http.defaults.headers.common['Authorization'] = 'Basic ' + Base64.encode(username + ':' + password);
};
Logout - call this when a user logs out
function clearCredentials() {
$http.defaults.headers.common.Authorization = 'Basic ';
};
The above snippets simplified from this tutorial - AngularJS Basic HTTP Authentication Example. i recommend reading it
In addition,
Please note that using basic http authentication is insecure because the password passed on each request with no encryption!
As an alternative, you can change basic http authentication to a server side authentication using sessions (comment the server your'e using and i'll link you to example)
If you still decides to keep the basic http authentication, at least use HTTPS !
I've found this solution working:
When initiating a logout, first try making a bad request with a fake user to throw away the currently cached credentials.
I have this function doing the requests (it's using jquery's $.ajax with disabled asynch calls):
function authenticateUser(username, hash) {
var result = false;
var encoded = btoa(username + ':' + hash);
$.ajax({
type: "POST",
beforeSend: function (request) {
request.setRequestHeader("Authorization", 'Basic ' + encoded);
},
url: "user/current",
statusCode: {
401: function () {
result = false;
},
200: function (response) {
result = response;
}
},
async: false
});
return result;
}
So when I try to log a user out, this happens:
//This will send a request with a non-existant user.
//The purpose is to overwrite the cached data with something else
accountServices.authenticateUser('logout','logout');
//Since setting headers.common.Authorization = '' will still send some
//kind of auth data, I've redefined the headers.common object to get
//rid of the Authorization property
$http.defaults.headers.common = {Accept: "application/json, text/plain, */*"};
