laravel实现json格式的异步分页

直接上代码

<?php
/**

namespace ***;
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Pagination\Paginator;

class FlowServer {
    /**
    * 是我
    */
    public function flow_info($request,$where,$time,$page_num){
        $where = [];
        $info = $table
            ->where($where)
            ->get();
        $perPage = $page_num;  //每页显示数据条数
        $total = count($info); //数据总条数
        $page_info = [];
        foreach($info as $v){ 
            $page_info[] = $v; 
        }
        if($request->has('page')) {
            $current_page = $request->input('page');
            $current_page = $current_page <= 0 ? 1 :$current_page;
        } else {
            $current_page = 1;
        }
        $total_page = ceil($total/$page_num);
        $item = array_slice($page_info, ($current_page-1)*$perPage, $perPage);
        $paginator =new LengthAwarePaginator($item, $total, $perPage, $current_page, [
            'path' => Paginator::resolveCurrentPath(),
            'pageName' => 'page',
        ]);
        $list = $paginator->toArray()['data'];
        $re['list'] = $list;
        $re['total_page'] = $total_page;
        return $re;
    }
}
