一切正常，没有错误，但问题是当我将 makeHidden 与我的代码一起使用时，它会更改我的 json 分页结果的结构

这是我的代码
$result = Job::where('user_id','=',Auth::id())->paginate(5);
$result= $result->makeHidden(['hasMessage']);
without the second line the result is
没有第二行，结果是
{
total: 1 ,
per_page: 5,
current_page: 1,
last_page: 1,
next_page_url: null,
prev_page_url: null,
from: 1,
to: 1,

有什么想法吗？? ? 这是一个错误还是有什么问题？?
hasMessageis an append field not a real columns
hasMessage是一个附加字段，而不是真正的列

$data = $paginator->makeHidden(['hasMessage']);
$paginator->data = $data;
return $paginator;

谢谢你

if you want to preserve pagination data use getCollection()and setCollection()methods:
如果要保留分页数据使用getCollection()和setCollection()方法：
$paginator = Job::where('user_id','=',Auth::id())->paginate(5);
$paginator->setCollection($paginator->getCollection()->makeHidden(['hasMessage']));
return $paginator;

You are missing toArray()in your code. It should be like:
您toArray()的代码中缺少。它应该是这样的：
$result= $result->makeHidden(['hasMessage'])->toArray();
Have a look at the docs:
看看文档：
https://laravel.com/docs/5.4/eloquent-serialization#hiding-attributes-from-json
https://laravel.com/docs/5.4/eloquent-serialization#hiding-attributes-from-json
Edit:
编辑：
I also have tried to paginateand it did return the changed array and it is the expected output for the makeHidden().
我也尝试过paginate，它确实返回了更改后的数组，它是makeHidden().
You could also have a look at the function:
你也可以看看这个函数：
public function makeHidden($attributes)
{
$attributes = (array) $attributes;
$this->visible = array_diff($this->visible, $attributes);
$this->hidden = array_unique(array_merge($this->hidden, $attributes));
return $this;
}
As it is doing array_mergeit distotes your json response.
因为它正在做array_merge它distotes你的json响应。
