如何在AngularJs中获得基本身份验证？我在谷歌上搜索过，但资源对我不起作用。我是AngularJS 的新手

假设您的html定义如下：

<!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>

您可以使用以下基本身份验证使后端连接到rest api：

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.
            });
}

请注意，此代码的大部分是Base64方法。如果您不需要支持IE9及更低版本，您可以用原生JS实现-atob（）和btoa（）来代替它：https://developer.mozilla.org/en/docs/web/api/windowbase64/atob

对我来说，这总是在实际工作之前报告401。我相信这是一个角度代码的错误，但我不确定。我在这里创建了一个问题：https://github.com/angular/angular.js/issues/3406
