ES for Laravel

Usage
EsBuilder 有兩種模式

  1. ES ORM Client (ORM模式)：支援Model對映
  2. ES Client (非ORM模式)：支援原生ES

使用 ES ORM Client
首先建立ORM Model


use Ethansmart\EsBuilder\Model\EsModel;

/**
 * Class AtPerson
 * $host ES IP或URL地址
 * $port ES 埠
 * $index ES 索引名稱
 * $type ES 索引 type名稱
 * @package Ethan\EsBuilder\Model
 */

class AtPerson extends EsModel
{
    protected $host = "127.0.0.1";
    protected $port = "32800";
    protected $index = "accounts";
    protected $type = "person";
}

然後使用Model對ES進行CURD操作

搜尋


try {
    $result = AtPerson::build()
              ->select("user")
              ->where("user",'==',"chengluo")
              ->where("title,desc","like","AI")
              ->where("create_time","<","2018-10-05")
              ->get();

} catch (\Exception $e) {
    return ['code'=>-1, 'msg'=>$e->getMessage()];
}

return $result;

新增


try {
    $id = 5;
    $data = [
       'id'=>$id,
       'params'=>[
            'user'=>'Ethan Cheng',
            'title'=>'AI '.str_random(8),
            'desc'=>'AI '.str_random(12)
       ]
    ];
    $result = AtPerson::build()->create($data);
} catch (\Exception $e) {
    return ['code'=>-1, 'msg'=>$e->getMessage()];
}

return $result;

更新


try {
    $id = 5;
    $data = [
        'id'=>$id,
        'params'=>[
             'user'=>'Ethan Cheng',
             'title'=>'AI '.str_random(8),
             'desc'=>'AI '.str_random(12)
        ]
    ];
    $result = AtPerson::build()->update($data);
} catch (\Exception $e) {
    return ['code'=>-1, 'msg'=>$e->getMessage()];
}

return $result;

刪除


try {
    $id = 5;
    $result = AtPerson::build()->delete($id);
} catch (\Exception $e) {
    throw $e;
}

return $result;

使用 ES Client
首先構建 Client


private $client ;

public function __construct()
{
     $host = "127.0.0.1";
     $port = "32800";
     $this->client = EsClientBuilder::create()
         ->setHosts($host)
         ->setPort($port)
         ->build();
}

呼叫Client中的方法對ES進行CURD操作


$data = [
     'index'=>'accounts',
     'type'=>'person',
     'body'=>[
          "query"=>[
               "bool"=>[
                   "must"=>[
                         "match"=>[
                              "user"=>"ethan"
                         ]
                   ]
               ]
          ]
     ],
];

try {
    $result = $this->client->search($data);
} catch (\Exception $e) {
    return ['code'=>-1, 'msg'=>$e->getMessage()];
}
return $result;

其他方法類似

建立Laravel Job 同步資料到 ES

use Ethansmart\EsBuilder\Builder\EsClientBuilder;

class EsService
{
    private $client ;
    public function __construct()
    {
        $host = "127.0.0.1";
        $port = "32800";
        $this->client = EsClientBuilder::create()
            ->setHosts($host)
            ->setPort($port)
            ->build();
    }

    public function create($id)
    {
        $data = [
            'index'=>'accounts',
            'type'=>'person',
            'id'=>$id,
            'body'=>[
                'user'=>str_random(6),
                'title'=>str_random(12),
                'desc'=>str_random(16),
            ]
        ];
        try {
            $result =  $this->client->create($data);
        } catch (\Exception $e) {
            return ['code'=>-1, 'msg'=>$e->getMessage()];
        }

        return $result;
    }
}

Q:
在使用 composer 安裝過程中會出現 如下異常：
[InvalidArgumentException]
Could not find a version of package ethansmart/es-for-laravel matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability.
解決方法：
在專案composer.json檔案中加入：

"repositories": [
        {
            "packagist.org": false
        },
        {
            "type": "composer",
            "url": "https://packagist.org"
        }
    ],

將國內的composer映象換成 packagist.org 就可以了。
