标签: angularjs spring spring-security

我的前端代码基于此链接http://embed.plnkr.co/toe4XO/authentication/service.js文件除外,我将代码更改为以下内容:

'use strict';

angular.module('Authentication')

.factory('AuthenticationService',
    ['Base64', '$http', '$cookieStore', '$rootScope', '$timeout',
    function (Base64, $http, $cookieStore, $rootScope, $timeout) {
        var service = {};

        service.Login = function (username, password, callback) {

            /* Dummy authentication for testing, uses $timeout to simulate api call
             ----------------------------------------------*/
            //$timeout(function(){
            //    var response = { success: username === 'test' && password === 'test' };
            //    if(!response.success) {
            //        response.message = 'Username or password is incorrect';
            //    }
            //    callback(response);
            //}, 1000);


            /* Use this for real authentication
             ----------------------------------------------*/
            $http.post('http://localhost:8080/AngularSpringBackend/authenticate', { username: username, password: password })
                .success(function (response) {
                    callback(response);
                });

        };

        service.SetCredentials = function (username, password) {
            var authdata = Base64.encode(username + ':' + password);

            $rootScope.globals = {
                currentUser: {
                    username: username,
                    authdata: authdata
                }
            };

            $http.defaults.headers.common['Authorization'] = 'Basic ' + authdata; // jshint ignore:line
            $cookieStore.put('globals', $rootScope.globals);
        };

        service.ClearCredentials = function () {
            $rootScope.globals = {};
            $cookieStore.remove('globals');
            $http.defaults.headers.common.Authorization = 'Basic ';
        };

        return service;
    }])

.factory('Base64', function () {
    /* jshint ignore:start */

    var keyStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=';

    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)) {
                window.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;
        }
    };

    /* jshint ignore:end */
});

我将所有前端代码放入IIS文件夹。我的后端代码需要基本身份验证才能访问API,并且url位于localhost中的端口8080下,所有登录信息也已存储在数据库中。

我的后端实现是Spring / Hibernate,我使用postman测试它,它可以正常工作。现在,如果我尝试从前端页面单击登录按钮,登录页面将保持循环,并且控制台会给出以下错误: Error message from Chrome,我做错了什么?

预期的行为应该是当用户输入有效帐户时,它可以访问api,也可以进入主页。

这是我的后端代码在github.com/zhengye1/SpringAngular

感谢您的帮助。

更新(2017年4月12日) Github代码根据以下评论进行更新。但我仍然没有得到我想要的东西。

回复Ajit Soman的评论: 在postman中,当我粘贴我的url链接时,例如http://localhost:8080/AngularSpringBackend/api/v1/users/,然后单击Authorization,选择Type is Basic Auth,输入admin / admin作为用户名和密码,它返回用户列表,可以检索来自数据库。

在我阅读https://samerabdelkafi.wordpress.com/2016/01/25/secure-angularjs-application-with-spring-security/之后,我的理解是在service.js中,我需要将帖子调用更改为http://localhost:8080/AngularSpringBackend/authenticate。现在我在Chrome中输入http://localhost/SimpleTest/#/login,在登录页面输入admin / admin作为用户名和密码,点击登录,弹出安全将处理其余部分并使身份验证成功并路由到主页,但似乎不是这种情况,我误解了什么吗?

更新(2017年4月18日) 最后得到我想要的,但它可能有安全问题。我的方式是'authentication / service.js',我改为 ```service.Login = function(用户名,密码,回调){               var base64Credentials = btoa(username +':'+ password);               的console.log(base64Credentials);

            console.log(username + ":" + password);
            /* Dummy authentication for testing, uses $timeout to simulate api call
             ----------------------------------------------*/
            //$timeout(function(){
            //    var response = { success: username === 'test' && password === 'test' };
            //    if(!response.success) {
            //        response.message = 'Username or password is incorrect';
            //    }
            //    callback(response);
            //}, 1000);


            /* Use this for real authentication
             ----------------------------------------------*/
        var req = {
            method: 'POST',
            url: 'http://localhost:8080/AngularSpringBackend/login?username='+username ,
            headers: {
            'Authorization': 'Basic ' + base64Credentials,
            'Access-Control-Allow-Origin': '*',
            'content-type' : 'application/x-www-form-urlencoded'
            }
        };
    $http(req).then(function (response) {
    callback(response);

在我的后端,我需要添加一个控制器类,将“/ login”路径映射到login方法,使用path变量获取用户名,指定POST和OPTIONS的方法,一切正常。

是否有任何好方法可以达到我想要的其他方法的要求?

在你的corsFilter @Component中缺少注释。所以请像这样添加@component

@Component
    public class CORSFilter implements Filter{
        static final Logger logger = LoggerFactory.getLogger(CORSFilter.class);
        public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) 
                throws IOException, ServletException {
    ...
}

@Component表示自动扫描组件,这将让您的spring容器自动扫描CORSFilter。
