Hyperf records using ElasticSearch

Hyperf installs the Elasticsearch coroutine client

hyperf/elasticsearch mainly encapsulates the factory class of client object creation for elasticsearch-php. elasticsearch-php uses the Guzzle Ring client by default. In hyperf/guzzle, we implement the coroutine version of Handler, so you can directly use Hyperf\Elasticsearch \ClientBuilderFactory creates a new Builder.

• Install

composer require hyperf/elasticsearch

• create client

class ElasticsearchService
{
    protected $container;
    protected Client $es_client;

    public function _initialize(): void
    {
        $this->container = ApplicationContext::getContainer();
        $client_builder = $this->container->get(ClientBuilderFactory::class);
        $builder = $client_builder->create();
        $host = [
            'https://账号:密码@地址:9200'
        ];

        $this->es_client = $builder->setHosts($host)->build();
    }

}

The account password here refers to the account password when creating elasticsearch. If you use Alibaba Cloud or Tencent Cloud services, there will also be

Here we just create a coroutine client, and the actual method inside needs to be redefined by ourselves

Basic steps of development

1 Install the es service, which can also be Tencent Cloud or Alibaba Cloud. Tencent Cloud and Alibaba Cloud only provide es services, and cannot directly see the data. The data still needs to be viewed in kibana.

2 Create a coroutine client

3 Create an index. index is equivalent to the library in mysql

4 Create mapping Mapping can be understood as a table. To store data, you must first define a table.

5 The index method pushes a single piece of data. bulk Push data in batches

6 search Search data.
