【中文标题】使用自定义 json 函数检索数据时分页不起作用【英文标题】：Pagination not working while retriving data with costom json function 【发布时间】：2022-01-09 15:38:26 【问题描述】：我正在获取数据以进行分页，但分页不起作用，获取响应添加在下面，如果我返回查询关系，它会检索正确的数据，但是当我将它传递给自定义响应函数时，它只获取数据而不是分页链接
try
$type = 'success';
$status_code = 200;
$message = 'Posts data listed.';
$response = PostResource::collection(Post::with(['associate:id,name,avatar', 'comments:id,commenter_id,commentable_id,comment,created_at'])
->latest('posts.created_at')
->paginate(2));
catch (Exception $e)
$type = 'error';
$status_code = $e->getCode();
$message = $e->getMessage();
$response = false;
return response_data($type, $status_code, $message, $response);
这是我的 response_data 函数代码
function response_data($type, $status, $message = false, $response)
return response()->json(['type' => $type, 'status' => $status, 'message' => $message, 'response' => $response]);
但是如果直接返回查询，它会使用分页检索数据 这是集合检索到的我的回复

如何解决并获取分页链接以及上面获取的数据
【问题讨论】：
定义它是如何不工作的？ 只有数据正在获取，但没有显示分页链接。 你用的是哪个 laravel 版本？ 我使用的是 laravel 8 版 因为您使用的是 PostResource::collection 方法，所以您正在改变（更改）实际数据。所以如果你删除它，或者如果你修改 PostResource 类以返回你需要的那些元数据。 【参考方案1】：Laravel 分页器结果类实现了Illuminate\Contracts\Support\Jsonable 接口契约并公开了toJson 方法，因此将分页结果转换为 JSON 非常容易。
您也可以将分页器实例转换为 JSON，只需从路由或控制器操作中返回即可：
