引入卡片 Card | Lin UI
json:

"usingComponents": {
"l-search-bar":"/miniprogram_npm/lin-ui/search-bar",
"l-card":"/miniprogram_npm/lin-ui/card"
}
}
php:
1.下载laravel8 支持的es插件
composer require elasticsearch/elasticsearch
2.在要使用的地方引入ES
use Elasticsearch\ClientBuilder;
3.生成ES对象
$client = ClientBuilder::create()‐>setHosts('连接地址')‐>build();
具体代码:
/**
* 添加索引
*/
public function create($results)
{
$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
if (!empty($results)){
$data=[
'id' => $results[0]['id'],
'title' => $results[0]['title'],
'image'=>$results[0]['image'],
'author' => $results[0]['author'],
'text'=>$results[0]['text']
];
}else{
$data=[
'id' => 3,
'title' => '我们的婚姻',
'image'=>'https://img1.baidu.com/it/u=3834462090,3152406810&fm=253&fmt=auto&app=138&f=JPEG?w=500&h=745',
'author' => 'XXXX',
'text'=>'把持都把持不住!'
];
}
//拼接数据
$params = [
'index' => 'article',
'type' => '_doc',
'id' => $data['id'],
'body' => $data
];
//存储到es中
$response = $client->index($params);
return $response;
}
/**

public function showArticle()
{
$data = Article::orderBy('id','desc')->get();
return ['code'=>200,'msg'=>'展示成功','data'=>$data];
}
/**

*/
public function selectArticle(request $request)
{
$title = $request->get('title');
$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
$params = [
'index' => 'article',
'type' => '_doc',

'post_tags'=>[

]
]
]
]
]
];
$results = $client->search($params);
//如果es里有数据 走es高亮显示
if ($results['hits']['hits']){
foreach ($results['hits']['hits'] as $key => $item)
{
$results['hits']['hits'][$key]['_source']['title'] = $item['highlight']['title'][$key];
}
$results = array_column($results['hits']['hits'], '_source');
return ['code'=>200,'msg'=>'es搜索成功','data'=>$results];
}else{
//没有数据就查询数据库然后再把数据添加到es索引中
$where= [];
$where[] = ['title','like',"$title"];
$results = Article::where($where)->get()->toArray();
//调用添加es方法
$this->create($results);
return ['code'=>200,'msg'=>'搜索成功','data'=>$results];
}
}
/**

* [@return](/user/return) array|callable
*/
public function upArticle()
{
$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
//测试数据
$data=[

'image'=>'https://img1.baidu.com/it/u=3834462090,3152406810&fm=253&fmt=auto&app=138&f=JPEG?w=500&h=745',

/**

public function deleteArticle()

//测试数据
$data=[

注意一定要先开起 elasticsearch 我用的es 6.5.3版本
