Question

我正在使用angular的$ resource来从API获取数据。我的angular $资源配置如下：

Priorities : $resource (baseUrl + 'priorities/:priorityType/:uuid/all', {}, {
    query : {
        method: 'GET',
        params: {
            priorityType : '@priorityType',
            uuid : '@uuid'
        },
        isArray: true
    }
})

但是，在调用Priorities.query时会调用$ resource：抛出badcfg错误：“包含数组但得到对象的预期响应”。此异常意味着API返回了一个对象，但$ resource配置为接收一个数组 - 但API显然返回一个数组：

[{"priority":"ONE","count":5,"globalCount":3037}]

深入了解angular-resource.js，抛出异常：

if (angular.isArray(data) !== (!!action.isArray)) {
  throw $resourceMinErr('badcfg', ...);
}

按预期!!action.isArray返回true，但奇怪的是angular.isArray(data)返回false。这是怎么回事？

需要从json转换响应。

class Banner extends SortableObject {

    private static $db = array(
    );

    private static $has_one = array(
        'HomePage' => 'HomePage',
        'Image' => 'Image',
        'SmallImage' => 'SmallImage',
        'Target' => 'Page',
    );

    private static $summary_fields = array(
        'ID',
        'Target.MenuTitle',
    );

    public function getCMSFields() {
        $fields = new FieldList();

        $img = new UploadField('Image');

        $img->setFolderName('hpbanners');
        $img->getValidator()->setAllowedExtensions(array('jpg','gif','png'));
        $fields->push($img);

        $smallImage = new UploadField('SmallImage');
        $smallImage->getValidator()->setAllowedExtensions(array('jpg','gif','png'));
        $fields->push($smallImage);

        $drop = new TreeDropdownField('TargetID','Choose page','SiteTree');
        $fields->push($drop);

        return $fields;
    }
}

Angular.isArray（data）为Array返回false
