本文实例讲述了thinkphp5框架前后端分离项目实现分页功能的方法。分享给大家供大家参考，具体如下：

方法一

利用tp5提供的paginate方法实现自动分页

参数

page第几页，paginate分页方法会自动获取

size  每页数量

代码

/**
* Notes:消费记录
* Date: 2019/6/25
* Time: 15:43
* @param Request $request
* @return \think\response\Json
*/
public function getMyConsumeLog(Request $request)
{
 global $_W;
 $size = $request->param('size', 6);
 $list = $this->model->getListByMid($_W['user']['id'],$size);
 return json(['data' => $list, 'error' => 0, 'message' => 'success']);
}
public function getListByMid($mid,$size = 10){
 $res = $this
 ->alias('c')
 ->field('c.*,b.book_name,b.book_flash,s.section_title')
 ->leftJoin('booksection s','c.chapter_id = s.id')
 ->leftJoin('book b','s.book_id = b.id')
 ->where('c.mid',$mid)
 ->order('c.id desc')
 ->paginate($size);
 return $res;
}

返回数据

{     "data": {         "total": 1,         "per_page": 1,         "current_page": 1,         "last_page": 1,         "data": [             {                 "id": 105,                 "mid": 55,                 "book_id": 31,                 "chapter_id": 46046,                 "score": 27,                 "create_time": 1561447448,                 "book_name": "桃运村支书",                 "book_flash": "https://cdnxiaoshuo.t.com/FiO6TM0N4kpzKB7tqrDko64ZS4H4",                 "section_title": "第29章 康庄大道"             }         ]     },     "error": 0,     "message": "success" }

方法二

利用limit方法

$curr_page = $request->param('page', 1);
 $size = $request->param('size', 6);
$list = $consume_model->getListByWhere($curr_page, $size, $where);
 $num = $consume_model->getListByWhereCount($where);
 return json(['data' => $list,'num' => $num,'error' => 0, 'message' => 'success']);
public function getListByWhere($curr_page,$limit = 10,$where = null){
 $res = $this
 ->alias('c')
 ->field('c.*,b.book_name,s.section_title')
 ->leftJoin('booksection s','c.chapter_id = s.id')
 ->leftJoin('book b','s.book_id = b.id')
 ->where($where)
 ->order('c.id desc')
 ->limit($limit*($curr_page - 1),$limit)
 ->select()
 ->toArray();
 return $res;
}
public function getListByWhereCount($where = null){
 $count = $this
 ->alias('c')
 ->where($where)
 ->count();
 return $count;
}

返回值

{     "data": [         {             "id": 2,             "mid": 4,             "book_id": 4,             "chapter_id": 22,             "score": 30,             "create_time": 0,             "book_name": "复仇者联盟I",             "section_title": "第11章  你是睡"         },         {             "id": 1,             "mid": 4,             "book_id": 29,             "chapter_id": 34,             "score": 20,             "create_time": 1598999,             "book_name": "复仇者联盟II",             "section_title": "第11章  你是睡"         }     ],     "num": 2,     "total_coin": 50,     "error": 0,     "message": "success" }
