Question

我无法使用AngularJs将RequestVerificationToken从网页传递到服务器。

我的AngularJs代码是：

var app = angular.module('validation', []);
app.controller('SignUpController', function ($scope, $http) {
    $scope.model = {};
    $scope.email = {};
    $scope.sendEmail = function () {
        $http({
            method: 'POST',
            url: '/Contact/Test',
            data: $scope.email,
            headers: {
                'RequestVerificationToken': $scope.antiForgeryToken
            }
        }).success();
    };
});

自定义属性代码：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public class CustomAntiForgeryTokenAttribute : FilterAttribute, IAuthorizationFilter
    {


        private void ValidateRequestHeader(HttpRequestBase request)
        {
            string cookieToken = String.Empty;
            string formToken = String.Empty;
            string tokenValue = request.Headers["RequestVerificationToken"];
            if (!String.IsNullOrEmpty(tokenValue))
            {
                string[] tokens = tokenValue.Split(':');
                if (tokens.Length == 2)
                {
                    cookieToken = tokens[0].Trim();
                    formToken = tokens[1].Trim();
                }
            }
            AntiForgery.Validate(cookieToken, formToken);
        }

        public void OnAuthorization(AuthorizationContext filterContext)
        {

            try
            {
                if (filterContext.HttpContext.Request.IsAjaxRequest())
                {
                    ValidateRequestHeader(filterContext.HttpContext.Request);
                }
                else
                {
                    AntiForgery.Validate();
                }
            }
            catch (HttpAntiForgeryException e)
            {
                throw new HttpAntiForgeryException("Anti forgery token cookie not found");
            }
        }
    }

表格是：

@functions{
    public string GetAntiForgeryToken()
    {
        string cookieToken, formToken;
        AntiForgery.GetTokens(null, out cookieToken, out formToken);
        return cookieToken + ":" + formToken;
    }
}
<div ng-app="validation" ng-controller="SignUpController">
    <form role="form" id="frmContact" action="@Url.Action("Index", "Contact")" method="POST">
        <input id="antiForgeryToken" ng-model="antiForgeryToken" type="hidden" ng-init="antiForgeryToken='@GetAntiForgeryToken()'" />
        <fieldset class="form-group">
            @Html.LabelFor(x => x.EmailTitle)
            @Html.TextBoxFor(x => x.EmailTitle, new { placeholder = @Resource.EmailTitle, @class = "form-control", data_ng_model = "new.email.title" })
        </fieldset>
        <fieldset class="form-group">
            @Html.LabelFor(x => x.EmailAddress)
            @Html.TextBoxFor(x => x.EmailAddress, new { placeholder = @Resource.EmailAddress, @class = "form-control", data_ng_model = "new.email.address" })
        </fieldset>
        <fieldset class="form-group">
            @Html.LabelFor(x => x.EmailMessage)
            @Html.TextAreaFor(x => x.EmailMessage, new { placeholder = @Resource.EmailMessage, @class = "form-control", data_ng_model = "new.email.message" })
        </fieldset>


        <div>
            <button type="submit" name="btnEmailForm" id="btnEmailForm" class="btnLogin" ng-click="sendEmail()" value="sendMessage">@Resource.ContactFormSendMessageButton</button>
        </div>
        <div id="errorMessages" class="error">{{message}}</div>
    </form>
</div>

我已经阅读了以下帖子，但似乎无法解决问题，并且还从https://github.com/techbrij/angularjs-asp-net-mvc获取了代码，该代码在该示例中有效但在我的MVC应用程序中无效：

Answer 1

在这种情况下，您执行表单submit和$scope.sendEmail操作，它们可能会相互冲突，以防止出现此行为，您可以使用ng-submit指令。并且还将属性name= '__RequestVerificationToken'和ng-value="antiForgeryToken"添加到相应的input。

Answer 2

重要提示：[ValidateAntiForgeryToken]的默认行为期望表单值中的__RequestVerificationToken令牌。要将请求以格式值格式发送到服务器，需要将content-type设置为application/x-www-form-urlencoded。但是很不幸，我没有此选项，我的内容类型是application/json。因此，我采用了这种自定义路径。

让我解释一下我采用的方法。

步骤1：在视图（.cshtml）中声明@Html.AntiForgeryToken()，如下所示：

<form id="inputForm" name="inputForm" ng-submit="submit(broker)" novalidate>
        @Html.AntiForgeryToken()
        /* other controls of form */
</form>

步骤2：@Html.AntiForgeryToken()将呈现一个隐藏字段，该字段将令牌值保存为：

<input name="__RequestVerificationToken" type="hidden" value="GvTcz2tTgHOS2KK_7jpHvPWEJPcbJmHIpSAlxY1">

第3步：为防伪令牌验证创建自定义属性，

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false)]    
public class HbValidateAntiForgeryToken : FilterAttribute, IAuthorizationFilter, IExceptionFilter    
{    
    public void OnAuthorization(AuthorizationContext filterContext)
    {
        try
        {
            var antiForgeryCookie = filterContext.HttpContext.Request.Cookies[AntiForgeryConfig.CookieName];
            AntiForgery.Validate(antiForgeryCookie != null ? antiForgeryCookie.Value : null,
                filterContext.HttpContext.Request.Headers["__RequestVerificationToken"]);                
        }
        catch (Exception ex)
        {                
            throw new SecurityException("Unauthorised access detected and blocked");
        }
    }

    public void OnException(ExceptionContext filterContext)
    {
        if (filterContext.Exception != null &&
            filterContext.Exception is System.Security.SecurityException)
        {
            filterContext.Result = new HttpUnauthorizedResult();
            // Handle error page scenario here
        }
    }
}

第4步：在需要的地方声明上述属性（仅在控制器的HttpPost方法上。请勿在HttpGet上声明）

[HttpPost]
[HbValidateAntiForgeryToken]
public JsonResult IsUsernameExists(string username)
{
}

第5步：在AngularJS中，在工厂通过__RequestVerificationToken作为标题。

hbServices.factory('RegistrationService', ['$resource',
function ($resource) {
    return $resource(applicationPath + 'api/MyUserMembership/:dest', {}, {
        createNewUser: { method: 'POST', isArray: false, params: { dest: 'CreateNewUser' }, 
                         headers: { 
                             '__RequestVerificationToken': $('input[name="__RequestVerificationToken"]').val()
                            }
                        },
        isUsernameExists: { method: 'POST', isArray: false, params: { dest: 'IsUsernameExists' }, 
        headers: { 
            '__RequestVerificationToken': $('input[name="__RequestVerificationToken"]').val()
           }
       }
    });
}]);

请注意，我传递__RequestVerificationToken值的方式是从ASP.NET MVC的@Html.AntiForgeryToken()呈现的隐藏字段中读取的。

我的应用程序正在使用jquery，并且已经具有jquery的引用，因此读取值很容易。您可以尝试其他方法读取此值

摘要 AntiForgery.Validate()在这里具有验证伪造令牌的价值的魔力，到目前为止还很不错。希望这会有所帮助！

所需的防伪表格字段＆＃34; __ RequestVerificationToken＆＃34;不在场。 AngularJs MVC
