使用Angular.js拦截器捕获HTTP 401

在应用程序配置块中：

var interceptor = ['$rootScope', '$q', "base64", function(scope, $q, base64) {  function success(response) {    return response;  }  function error(response) {    var status = response.status;    if (status == 401) {      //AuthFactory.clearUser();      window.location = "/account/login?redirectUrl=" + base64.enpre(document.URL);      return;    }    // otherwise    return $q.reject(response);  }  return function(promise) {    return promise.then(success, error);  }}];
