Laravel5.4手动创建分页

$page = $request->input("page",1)-1;
$perPage  = $this->getPerPage();
$total1 = DB::connection('')->table('')->whereRaw($direct_where)->count();
$total2 = DB::connection('')->table('')->whereRaw($book_where)->count();
$total=$total1+$total2;
$booth_book_order=DB::connection('')->table('')->select('')->whereRaw($book_where);

$book_direct_sum_order = DB::connection('')->table('')->select('')->whereRaw($direct_where)->unionAll($booth_book_order)->skip($page*$perPage)->take($perPage)->get();
$content = new LengthAwarePaginator($book_direct_sum_order, $total,$perPage);
//$content= $person->withPath("");
