Laravel 5:LengthAwarePaginator返回JSON而不是数组

Question

我从LengthAwarePaginator返回JSON,但JSON的data属性不是数组.我需要它成为一个数组.有任何想法吗？

// grab query parameters
$pageNumber = $request->input('page');
$pageSize = $request->input('pageSize');
// if query params do not exist call with defaults
if(!$pageNumber) {
  $pageNumber = 1;
}

if(!$pageSize) {
  $pageSize = 5;
}

$offset = ($pageNumber * $pageSize) - $pageSize;
// slice full array data based on page number and page size
$itemsForCurrentPage = array_slice($arrayOfData, $offset, $pageSize, true);
return new LengthAwarePaginator($itemsForCurrentPage, count($this->orgUsers), $pageSize, $pageNumber);

返回的数据:

{
"total": 30,
"per_page": 5,
"current_page": 2,
"last_page": 6,
"next_page_url": "/?page=3",
"prev_page_url": "/?page=1",
"from": 6,
"to": 10,
"data": {
    "5": {
    "userId": "564110eadcb39832268ea873",
    "email": "dsdfgdfg@il.com",
    "isActive": true,
    "firstName": "dsdfgdfg",
    "lastName": "dsdfgdfg",
    "permissionType": "dsdfgdfg"
    },
    "6": {
    "userId": "564110ea2169bc358a3b65c2",
    "email": "dsdfgdfg@d.com",
    "isActive": false,
    "firstName": "dsdfgdfg",
    "lastName": "dsdfgdfg",
    "permissionType": "dsdfgdfg"
    },
    "7": {
    "userId": "564110eaee662f30c4bd6772",
    "email": "dsdfgdfg@dsdfgdfg.com",
    "isActive": true,
    "firstName": "dsdfgdfg",
    "lastName": "dsdfgdfg",
    "permissionType": "dsdfgdfg"
    },
    "8": {
    "userId": "dsdfgdfg",
    "email": "dsdfgdfg@dsdfgdfg.com",
    "isActive": true,
    "firstName": "dsdfgdfg",
    "lastName": "dsdfgdfg"
    },
    "9": {
    "userId": "564110eaf9526eb5ddd673a4",
    "email": "dsdfgdfg@dsdfgdfg.com",
    "isActive": true,
    "firstName": "dsdfgdfg",
    "lastName": "dsdfgdfg"
    }
}
}

问题是ids当array_slice-ing 时仍然是数组的键.但是由于缺少某些键,特别0, 1, 2, …是当编码为json时,数组此后被视为associative(['key1'=>'value1', 'key2'=>'value2', …])而不是数字索引(['value1', 'value2', …]).

解决方案是array_slice(…)通过array_values()电话接替您.

return new LengthAwarePaginator(array_values($itemsForCurrentPage), count($this->orgUsers), $pageSize, $pageNumber);

编辑:如果你$arrayOfData是一个Eloquent/Illuminate Collection,你可以使用->slice($offset, $pageSize)->values()它上面的方法.看起来更好!
