Informations about the package es
es使用
-
项目要用到es,所以自己进行了一下简单的封装
- es版本2.3
安装
composer require ljw/es:dev-master
配置
//配置es
\Ljw\Es\Es::$hosts = '127.0.0.1';
\Ljw\Es\Es::$port = '9200';
开始使用
建立索引
- 创建一个类继承model
class Product extends \Ljw\Es\Model
{
//指定索引
protected $index = 'product_index';
//指定索引别名
protected $alias = 'product_alias';
//指定type
protected $type = 'products';
/**
* 索引设置
* @var array
*/
protected $setting = [];
/**
* 索引参数
* @var array
*/
protected $properties = [
'id' => ['type' => 'long'],
'name' => ['type' => 'string'],
'description' => ['type' => 'string'],
];
}
-
注:如果没有在类里面指定index,alias和type,会自动设置为
{class}_index | {class}_alias | {class}_type
{class} 为类名小写
- 运行
//创建索引。会根据Product中的$setting,$properties来创建 Product::createIndex(); //删除索引 Product::deleteIndex(); //跟新索引。根据Product中的$properties来跟新,只能进行追加,不能修改和删除字段 Product::updateIndex();
查询
- 直接查询
//简单查询,where只支持 = , > , < , >= , <= , between ; = 就相当于like了 // where ... or ... and (... or ...) order by `id` `desc` $query = \Ljw\Es\Es::query() ->index('pro_index') ->type('type') ->where(...) ->orWhere(...) ->where(function ($q) { $q->where(...)->orWhere(...); }) ->order('id', 'desc') ->page($page, $page_size) ->search(); $list = $query->getData(); //数据列表 $count = $query->getCount(); //数据总量 // --------------- // 聚合,支持 group,avg,sum,max,min $query = \Ljw\Es\Es::query() ->index('pro_index') ->type('type') ->where(...) ->group('xxx', function($q){ // group by xxx 并计算不同xxx下面aaa的和 $q->sum('aaa'); }) ->sum('id') // 计算id的和 ->search(); $data = $query->getData();
- 创建模型查询
class Product extends \Ljw\Es\Model { //指定索引 protected $index = 'product_index'; //指定索引别名 protected $alias = 'product_alias'; //指定type protected $type = 'products'; protected $setting = [...]; protected $properties = [...];
} $re = Product::query()->where(...)->orWhere(...)->search(); $list = $re->getData(); //数据列表 $count = $re->getCount(); //数据总量 $re = Product::query()->where(...)->orWhere(...)->group(...)->search(); $data = $re->getData();
### 添加,修改,删除数据
* 建立模型
~~~php
class Product extends \Ljw\Es\Model
{
//指定索引
protected $index = 'product_index';
//指定索引别名
protected $alias = 'product_alias';
//指定type
protected $type = 'products';
protected $setting = [...];
protected $properties = [...];
}
// $id 必须为唯一id, $data为数据,会根据 $properties 自动剔除
Product::add($id, $data);
//删除
Product::delete($id);
//跟新数据
Product::update($id, $data);
注:暂时就这些简单的功能了
