• 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 appindexcontroller;
    use thinkController;
    class Ec extends Controller
    {
        public function _initialize()
        {
         
            Vendor('Elasticsearch.autoload');
            $params['hosts'] = array(
                '192.168.9.155:9200'
            );
            $this->client = new ElasticsearchClient($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['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);

        }
