javascript - AngularJS 资源获取失败

Question

有谁知道如何在 AngularJS 中检查资源是否无法获取？

例如:

//this is valid syntax
$scope.word = Word.get({ id : $routeParams.id },function() {
    //this is valid, but won't be fired if the HTTP response is 404 or any other http-error code
});

//this is something along the lines of what I want to have 
//(NOTE THAT THIS IS INVALID AND DOESN'T EXIST)
$scope.word = Word.get({ id : $routeParams.id },{
    success : function() {
      //good
    },
    failure : function() {
      //404 or bad
    }
});

有什么想法吗？

当出现错误时，应在您的第一个回调函数之后触发一个额外的回调函数。取自 docs和组post :

$scope.word = Word.get({ id : $routeParams.id }, function() {
    //good code
}, function(response) {
    //404 or bad
    if(response.status === 404) {
    }
});

• HTTP GET "class" actions: Resource.action([parameters], [success], [error])
• non-GET "class" actions: Resource.action([parameters], postData, [success], [error])
• non-GET instance actions: instance.$action([parameters], [success], [error])
