Tambah semua data dalam jadual data ke ES
public function esAdd() { $data = Good::get()->toArray(); $es = new MyEs(); if (!$es->exists_index('goods')) { //创建es索引,es的索引相当于MySQL的数据库 $es->create_index('goods'); } foreach ($data as $model) { $es->add_doc($model['id'], $model, 'goods', '_doc'); } }
Setiap kali sekeping data ditambahkan dalam MySQL, ia adalah juga ditambah dalam es
Terus tambah kod pada kaedah logik untuk menambah MySQL ke pangkalan data
//添加至MySQL $res=Good::insertGetId($arr); $es = new MyEs(); if (!$es->exists_index('goods')) { $es->create_index('goods'); } //添加至es $es->add_doc($res, $arr, 'goods', '_doc'); return $res;
Apabila mengubah suai data MySQL, data es juga akan dikemas kini >
Tambah terus Kod boleh ditambah kepada kaedah logik untuk mengubah suai data dalam MySQL//修改MySQL的数据 $res=Good::where('id',$id)->update($arr); $es = new MyEs(); if (!$es->exists_index('goods')) { $es->create_index('goods'); } //修改es的数据 $es->update_doc($id, 'goods', '_doc',['doc'=>$arr]); return $res;
public function search() { //获取搜索值 $search = \request()->get('search'); if (!empty($search)) { $es = new MyEs(); $body = [ 'query' => [ 'match' => [ 'title' => [ 'query' => $search ] ] ], 'highlight'=>[ 'fields'=>[ 'title'=>[ 'pre_tags'=>[ '<span style="color: red">' ], 'post_tags'=>[ '</span>' ] ] ] ] ]; $res = $es->search_doc('goods', '_doc', $body); $data = array_column($res['hits']['hits'], '_source'); foreach ($data as $key=>&$v){ $v['title'] = $res['hits']['hits'][$key]['highlight']['title'][0]; } unset($v); return $data; } $data = Good::get(); return $data; }
