角茉莉测试响应拦截器

您应该使用最新的语法来构造拦截器定义。您的URL构造也应包含在服务中，以便可以在测试中轻松模拟它。

.factory('UnauthorizedInterceptor', function($q, $window, OtherService) {  var service = {    responseError: handleUnauthorized  };  return service;  function handleUnauthorized(rejection) {    if (rejection.status === 401) {      $window.location.href = OtherService.getUnauthorizedRedirectURL();    }    return $q.reject(rejection);  }});

这样做可以让您像其他任何工厂一样对其进行测试，而不必担心
