Sails.js：在angularjs post请求中传递csrf标记

Question

这是带有csrf令牌的表单

<form name="form" method="POST" ng-submit="login(user)" novalidate>
        <input type="hidden" ng-model="user._csrf" name="_csrf" value="<%= _csrf %>" />
......
....

</form>

如何通过http.post请求

传递此csrf令牌

$http.defaults.withCredentials = true;
         $scope.login = function (user) {

             //user login as post
             $http.post('/login',user).then(function (response) {
                 console.log(response.data);
             });
         }

当我提交上述请求时，我将收到csrf token not found错误
