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 *@paramRequest$request *@return\think\response\Json */ publicfunctiongetMyConsumeLog(Request$request) { global$_W; $size=$request->param('size',6); $list=$this->model->getListByMid($_W['user']['id'],$size); returnjson(['data'=>$list,'error'=>0,'message'=>'success']); } publicfunctiongetListByMid($mid,$size=10){ $res=$this ->alias('c') ->field('c.*,b.book_name,b.book_flash,s.section_title') ->leftJoin('booksections','c.chapter_id=s.id') ->leftJoin('bookb','s.book_id=b.id') ->where('c.mid',$mid) ->order('c.iddesc') ->paginate($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($where); returnjson(['data'=>$list,'num'=>$num,'error'=>0,'message'=>'success']); publicfunctiongetListByWhere($curr_page,$limit=10,$where=null){ $res=$this ->alias('c') ->field('c.*,b.book_name,s.section_title') ->leftJoin('booksections','c.chapter_id=s.id') ->leftJoin('bookb','s.book_id=b.id') ->where($where) ->order('c.iddesc') ->limit($limit*($curr_page-1),$limit) ->select() ->toArray(); return$res; } publicfunctiongetListByWhereCount($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"
}
