使用摘要身份验证对用户名和密码进行身份验证时，在Java脚本中出错

getting error in the javascript ,when authenticate the username and password using digest authentication(使用摘要身份验证对用户名和密码进行身份验证时，在Java脚本中出错)

问题描述

在这里，我想验证用户名和密码。在这里，我在控制台(ValuesUser)中成功地获得了用户名和密码。 我尝试了以下代码，

Ext.define('Form.controller.Digestauth', {
    extend: 'Ext.app.Controller',
    requires:['RegisterForm.view.Login','RegisterForm.view.Main'],
    config:{
        refs:{
            loginform: '#loginform'
        },
        control: {
            '#loginButton': {
                tap: function(){
                    var valuesUser = this.getLoginform().getValues();
                    console.log(valuesUser);
                    console.log(valuesUser.userName);
                    $.Class("pl.arrowgroup.DigestAuthentication",{
                        MAX_ATTEMPTS : 1,
                        AUTHORIZATION_HEADER : "Authorization",
                        WWW_AUTHENTICATE_HEADER : 'WWW-Authenticate',
                        NC : "00000001", //currently nc value is fixed it is not incremented
                        HTTP_METHOD : "GET",
                        /**

                            this.settings = settings;
                        },
                        setCredentials: function(username, password){
                            this.settings.username = valuesUser.username;
                            this.settings.password = valuesUser.userPassword;
                        },
                        call : function(uri){
                            this.attempts = 0;

                                success: function(response) {

                                    var paramParser = new pl.arrowgroup.HeaderParamsParser(response.getResponseHeader(digestAuth.WWW_AUTHENTICATE_HEADER));
                                    var nonce = paramParser.getParam("nonce");
                                    var realm = paramParser.getParam("realm");
                                    var qop = paramParser.getParam("qop");
                                    var response = digestAuth.calculateResponse(uri, nonce, realm, qop);
                                    var authorizationHeaderValue = digestAuth.generateAuthorizationHeader(paramParser.headerValue, response, uri);
                                    digestAuth.attempts++;

                            });
                    },
                            calculateResponse : function(uri, nonce, realm, qop){
                                var a2 = this.HTTP_METHOD + ":" + uri;
                                var a2Md5 = hex_md5(a2);
                                var a1Md5 = hex_md5(this.settings.username + ":" + realm + ":" + this.settings.password);
                                var digest = a1Md5 + ":" + nonce + ":" + this.NC + ":" + this.settings.cnonce + ":" + qop + ":" +a2Md5;
                                return hex_md5(digest);
                            },
                            generateAuthorizationHeader : function(wwwAuthenticationHeader, response, uri){
                                return wwwAuthenticationHeader+', username="'+this.settings.username+'", uri="'+

                    $.Class("pl.arrowgroup.HeaderParamsParser",{

                            this.headerParams = this.headerValue.split(",");
                        },
                        getParam: function(paramName){
                            var paramVal = null;
                            $.each(this.headerParams, function(index, value){
                                if(value.indexOf(paramName)>0){
                                    paramVal = value.split(paramName+"=")[1];
                                    paramVal = paramVal.substring(1, paramVal.length-1);
                                }
                            });
                            return paramVal;
                        }
                    });
                }
            }
        }
    }
});

要编写上述代码，我使用了"http://marcin-michalski.pl/2012/11/01/javascript-digest-authentication-restful-webservice-spring-security-javascript-ajax/"链接摘要-auth.js文件

我收到的错误是：未定义引用错误：$未定义。是否有人可以帮助我完成此操作。提前谢谢

推荐答案

需要包含jQuery。它定义了一个全局$变量，这就是您的错误所抱怨的。可能来自对$.ajax的调用。

查看此处的入门部分：http://docs.jquery.com/
