How can I get basic auth working in AngularJs? I've googled and the resources aren't working for me. I'm very new to AngularJS

Assuming your html is defined like this:



<!doctype html>
<html ng-app=sandbox-app>
<head>
<script src=https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js></script>
<script src=todo.js></script>
<link rel=stylesheet href=todo.css>
</head>
<body>
<h2>Todo</h2>
<div ng-controller=TodoCtrl>
<ol>
...
</ol>
</div>
</body>
</html>


You can make your backend connect to a rest api using basic auth like this:



var app = angular.module('sandbox-app', []);
app.config(function($httpProvider) {

});

app.factory('Base64', function() {
var keyStr = 'ABCDEFGHIJKLMNOP' +
'QRSTUVWXYZabcdef' +
'ghijklmnopqrstuv' +
'wxyz0123456789+/' +
'=';
return {
encode: function (input) {
var output = ;
var chr1, chr2, chr3 = ;
var enc1, enc2, enc3, enc4 = ;
var i = 0;

do {
chr1 = input.charCodeAt(i++);
chr2 = input.charCodeAt(i++);
chr3 = input.charCodeAt(i++);

enc1 = chr1 >> 2;
enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
enc4 = chr3 & 63;

if (isNaN(chr2)) {
enc3 = enc4 = 64;
} else if (isNaN(chr3)) {
enc4 = 64;
}

output = output +
keyStr.charAt(enc1) +
keyStr.charAt(enc2) +
keyStr.charAt(enc3) +
keyStr.charAt(enc4);
chr1 = chr2 = chr3 = ;
enc1 = enc2 = enc3 = enc4 = ;
} while (i < input.length);

return output;
},

decode: function (input) {
var output = ;
var chr1, chr2, chr3 = ;
var enc1, enc2, enc3, enc4 = ;
var i = 0;

// remove all characters that are not A-Z, a-z, 0-9, +, /, or =
var base64test = /[^A-Za-z0-9+/=]/g;
if (base64test.exec(input)) {
alert(There were invalid base64 characters in the input text.n +
Valid base64 characters are A-Z, a-z, 0-9, '+', '/',and '='n +
Expect errors in decoding.);
}
input = input.replace(/[^A-Za-z0-9+/=]/g, );

do {
enc1 = keyStr.indexOf(input.charAt(i++));
enc2 = keyStr.indexOf(input.charAt(i++));
enc3 = keyStr.indexOf(input.charAt(i++));
enc4 = keyStr.indexOf(input.charAt(i++));

chr1 = (enc1 << 2) | (enc2 >> 4);
chr2 = ((enc2 & 15) << 4) | (enc3 >> 2);
chr3 = ((enc3 & 3) << 6) | enc4;

output = output + String.fromCharCode(chr1);

if (enc3 != 64) {
output = output + String.fromCharCode(chr2);
}
if (enc4 != 64) {
output = output + String.fromCharCode(chr3);
}

chr1 = chr2 = chr3 = ;
enc1 = enc2 = enc3 = enc4 = ;

} while (i < input.length);

return output;
}
};
});

//here's where YOUR code is finally accessed
function TodoCtrl($scope, $http, Base64) {

$http.defaults.headers.common = {Access-Control-Request-Headers: accept, origin, authorization}; //you probably don't need this line. This lets me connect to my server on a different domain
$http.defaults.headers.common['Authorization'] = 'Basic ' + Base64.encode('admin' + ':' + 'abc12345');
$http({method: 'GET', url: 'http://localhost:8888/app/api/v1/pets'}).
success(function(data, status, headers, config) {
$scope.pets = data;
// this callback will be called asynchronously
// when the response is available
}).
error(function(data, status, headers, config) {
alert(data);
// called asynchronously if an error occurs
// or server returns response with an error status.
});

}


Note the majority of this code is the Base64 method. If you do not need to support IE9 and lower, you could replace it with native JS implementations - atob() and btoa(): https://developer.mozilla.org/en/docs/web/api/windowbase64/atob






For me, this always reports a 401 before it actually works. I believe this is a bug with the angular code but I'm not sure. I've created an issue here: https://github.com/angular/angular.js/issues/3406
