在laravel中访问ES聚合桶列表对象

Question

我正试图在laravel中访问Elasticquent聚合桶列表对象：

array:1 [▼   "group_by_law_year" => array:3 [▼
    "doc_count_error_upper_bound" => 0
    "sum_other_doc_count" => 0
    "buckets" => array:2 [▼
      0 => array:2 [▼
        "key" => "2013"
        "doc_count" => 2
      ]
      1 => array:2 [▼
        "key" => "2012"
        "doc_count" => 1
      ]
    ]   ] ]

我尝试过像$laws_y->getAggregations('group_by_law_year').get()，但没有成功。有人有想法吗？

Answer 1

getAggregations将返回一个数组（如上面的输出所示），因此您只需要检索buckets并迭代它们，如下所示：

$buckets = $laws_y->getAggregations()['group_by_law_year']['buckets'];
foreach ($buckets as $bucket){
   echo $bucket['key'] . ' = ' . $bucket['doc_count'];
}
