## 这是我的控制器索引方法。
如何为此方法应用过滤器。这里的bookFormat方法是获取结果的自定义方法。提前致谢。
public function index(){
$input = Input::only('skip','limit');
$books = Book::all();
$results = [];
foreach ($books as $book) {
$results [] = $this->bookFormat($book);
}
$skip = null;
if(isset($input['skip'])){
$skip = $input['skip'];
return $results->skip($skip);
}
$limit = null;
if(isset($input['limit'])){
$limit = $input['limit'];
return $results->limit($limit)->get();
}
return $results;
}

您可以选中import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

makePanel = new JPanel();
makePanel.setLayout(new BoxLayout(makePanel, BoxLayout.Y_AXIS));

public static void main(String[] args)

并最后应用isset或skip,take来执行此操作。
limit,offset或者您可以使用public function index(){
$input = Input::only('skip','limit');
$query = new Book();
if(isset($input['skip']) && $input['skip']){
$query = $query->skip($input['skip']);
}
if(isset($input['limit']) && $input['limit']){
$query = $query->take($input['limit']);
}
$books = $query->get();
$results = [];
foreach ($books as $book) {
$results [] = $this->bookFormat($book);
}
return $results;
}
获取Request $request和skip值
limit
