ElasticSearch(六) Elasticsearch在Thinkphp5.0中的使用

首先下载需要引入的类库

链接：https://pan.baidu.com/s/1XEXviLoWM-ypwJ_B0jXqlg 密码：u54t    //Elasticsearch.zip类库压缩包地址

然后将压缩包解压到vendor目录下

 

<?php
namespace app\index\controller;
use think\Controller;
class Ec extends Controller
{
    public function _initialize()
    {
     
        Vendor('Elasticsearch.autoload');
        $params['hosts'] = array(
            '192.168.9.155:9200'
        );
        $this->client = new \Elasticsearch\Client($params);
    }
    public function index(){
        $this->search();
    }
    
    //创建索引
    //现在我们开始添加一个新的索引和一些自定义设置：
    public function create_index()
    {
        $indexParams['index'] = 'myindex';                         //索引名称  
        $indexParams['type'] = 'mytype';                          //类型名称  
        $indexParams['body']['settings']['number_of_shards'] = 1;   //当前只有一台ES，1就可以了
        $indexParams['body']['settings']['number_of_replicas'] = 0; //副本0，因为只有一台ES
        $this->client->create($indexParams);
    }
    //插入索引数据
    public function add_document()
    {
        $params = array();
        $params['body'] = array(
            'product_name' => '要插入的商品名称'，
            'prodcut_id' => 5
        );
        $params['index'] = 'myindex';  //索引名称 
        $params['type'] = 'mytype';   //类型名称  
        $params['id'] = '12345678';     //不指定id，系统会自动生成唯一id  
        $ret = $this->client->index($params);
    }
    //删除索引
    //由于 elasticsearch 的动态性质，我们添加第一个文档的时候自动创建了索引和一些默认设置。让我们删除这个索引，因为我们以后想要指定自己的设置：
    public function delete_index()
    {
        $deleteParams['index'] = 'myindex';
        $this->client->indices()->delete($deleteParams);
    }
    //删除文档
    public function delete_document()
    {
        $deleteParams = array();
        $deleteParams['index'] = 'myindex';
        $deleteParams['type'] = 'mytype';
        $deleteParams['id'] = '123';
        $retDelete = $this->client->delete($deleteParams);

    //查询
