thinkphp5框架前后端分离项目实现分页功能的方法分析

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 thinkresponseJson
*/
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” }
