ES for Laravel

Usage

EsBuilder 有两种模式

1. ES ORM Client (ORM模式)：支持Model映射
2. ES Client (非ORM模式)：支持原生ES

使用 ES ORM Client

首先创建ORM Model

use Ethansmart\EsBuilder\Model\EsModel;
/**

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

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

然后使用Model对ES进行CURD操作

搜索

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;

删除

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

return $result;

使用 ES Client

首先构建 Client

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

调用Client中的方法对ES进行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;

其他方法类似

创建Laravel Job 同步数据到 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 安装过程中会出现 如下异常：

[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.

解决方法：

在项目composer.json文件中加入：

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

将国内的composer镜像换成 packagist.org 就可以了。
