thinkphp5前后端分离项目实现分页

 

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"
        },
        {

        }
    ],
    "num": 2,
