核心代码：

@if ($paginator->hasPages())
    @php
    //指定显示的页码数量，取值范围3-n
    $paging_number = 6;
    if($paging_number<3){
    $paging_number = 3;
    }
    //当前页
    $paging_current_page = $paginator->currentPage();
    //共几页
    $paging_last_page = $paginator->lastPage();
    if(($paging_number%2) == 0){
    if($paging_last_page <= $paging_number){
    $paging_start = 1;
    $paging_end = $paging_last_page;
    }else if($paging_current_page < ($paging_number/2+1)){
    $paging_start = 1;
    $paging_end = $paging_number;
    }else if($paging_current_page >= ($paging_number/2+1) && (($paging_current_page + ($paging_number/2 - 1)) <= $paging_last_page)){
    $paging_start = $paging_current_page - ($paging_number/2);
    $paging_end = $paging_current_page + ($paging_number/2 - 1);
    }else{
    $paging_start = $paging_last_page - $paging_number + 1;
    $paging_end = $paging_last_page;
    }
    }else{
    if($paging_last_page <= $paging_number){
    $paging_start = 1;
    $paging_end = $paging_last_page;
    }else if($paging_current_page < ceil($paging_number/2)){
    $paging_start = 1;
    $paging_end = $paging_number;
    }else if($paging_current_page >= ceil($paging_number/2) && (($paging_current_page + floor($paging_number/2)) <= $paging_last_page)){
    $paging_start = $paging_current_page - floor($paging_number/2);
    $paging_end = $paging_current_page + floor($paging_number/2);
    }else{
    $paging_start = $paging_last_page - ($paging_number - 1);
    $paging_end = $paging_last_page;
    }
    }
    @endphp
