Symfony 3 框架＋Elasticsearch

下载symfony

略

创建一个symfony 3 项目

代码语言：javascript复制

cd /var/www
symfony new search-www

修改composer.json，增加

代码语言：javascript复制

"require": {
...
    "elasticsearch/elasticsearch": "~5.3.0"
...
}

如果composer.json.lock存在，则删除。

安装elasticsearch 库

代码语言：javascript复制

cd /var/www/search-www
composer install

Symfony项目中创建一个Controller

目录src/AppBundle/Controller/SearchController.php

代码语言：javascript复制

<?php

namespace AppBundleController;

use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SymfonyBundleFrameworkBundleControllerController;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentHttpFoundationResponse;

use ElasticsearchClientBuilder;

class SearchController extends Controller
{
    /**
     * @Route("/search", name="homepage")
     */
    public function indexAction(Request $request)
    {
        $client = ClientBuilder::create()->build();

        $params = [
            'index' => 'scrapy.course',
            'type' => 'normal',
            'id' => '1'
        ];
        $response = $client->get($params);
        
        return new Response(json_encode($response));
    }
}

启动symfony服务

代码语言：javascript复制

app/console server:run

默认端口为8000

查询结果

http://localhost:8000/search

代码语言：javascript复制

{
    "_index":"scrapy.course",
    "_type":"normal",
    "_id":"1",
    "_version":1,
    "found":true,
    "_source":{
        "title":"Think in Java"
    }
}

注: 需要先搭建elasticsearch并插入数据，参见文档undefined 《Elasticsearch Kibana 起步》

参考文档 https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/_quickstart.html
