laravel 安装 curl扩展 实现Elasticsearch

• 本文适用于laravel5*

1. 安装curl扩展
   参考网站

https://packagist.org/packages/ixudra/curl?tdsourcetag=s_pctim_aiomsg
在composer.json文件中的require中加入
"ixudra/curl": "6.*",

或者
运行
composer require ixudra/curl
2.配置curl扩展
在config/app.php的providers数组中加入一段
Ixudra\Curl\CurlServiceProvider::class,
在config/app.php的aliases数组中加入一段
'Curl' => Ixudra\Curl\Facades\Curl::class,
接下来就可以使用curl扩展了

• 添加

 $jsonData=json_encode($data,true);
        $esRes=Curl::to($this->esPortUrl.$index.'/'.$type.'/'.$id)
            ->withData($jsonData)//传输数据
            ->withContentType('application/json')//头
            ->post();
        $res=json_decode($esRes,true);
        if(isset($res['error'])){
            //有错误
            return $this->returnJson('9'.$res['status'],$res['error']['type'],$res['error']['caused_by']);
        }
        return $this->returnJson('9200','index:'.$index.';type:'.$type.';id:'.$res['_id'],$res);

• 展示

$url='http://127.0.0.1:9400/'.$index.'/'.$type.'/_search';
        $esRes=Curl::to($url)
            ->get();
        $resArr=json_decode($esRes,true);
        if(isset($resArr['error'])){
            return $this->returnJson('9'.$resArr['status'],$resArr['type'],$resArr['root_cause']);
        }

        return $this->returnJson('9200','success',$resArr);

• 搜索高亮分页

        $url=$this->esPortUrl.$index.'/'.$type.'/_search';

        $data = [
            "query"=>[
                "match"=>[
                    "name"=>"$search"
                ]
            ],
            "from" => ($page-1)*3,
            "size" => 3,
            "highlight" => [
                "pre_tags" => [""],
                "post_tags" => [""],
                "fields" => [
                    "name" => new \stdClass()
                ]
            ]
        ];
        $res = Curl::to($url)
            ->withData(json_encode($data))
            ->withContentType('application/json')
            ->post();


        $resArr=json_decode($res,true);
        $arr=[];
        foreach ($resArr['hits']['hits'] as $v){
            $arr[]=array_merge(['id'=>$v['_id']],$v['_source']);
        }
//将es数据拼接成跟数据库格式一样
        return $arr;
