1.$sce.trustAs(type,name);
2.$sce.trustAsHtml(value);
3.$sce.trustAsUrl(value);
4.$sce.trustAsResourceUrl(value);
5.$sce.trustAsJs(value);
例如：
<i ng-bind-html="explicitlyTrustedHtml" id="explicitlyTrustedHtml"></i>
angular.module('mySceApp',[])
.controller('AppController', ['$scope', '$sce',
function($scope, $sce) {
$scope.explicitlyTrustedHtml = $sce.trustAsHtml(
'Hover over this text.');
}]);
// $scope.trustSrc = $sce.trustAsResourceUrl("http://fanyi.youdao.com/");
