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"
}
