php - 严重错误:找不到类 '..'

Question

我正在尝试通过symfony中的PHP API使用Elasticsearch。
我已经通过Elasticsearch安装了composer。

这是我的代码被称为:

<?php

namespace AppBundle\ElasticsearchQuery;
use Elasticsearch\ClientBuilder;

class ElasticsearchQuery
{
private $Host = ['http://localhost:9200'];
private $client;
private $index = "homestead";

public function  __construct()
{
    $this->client = Elasticsearch\ClientBuilder::create()
        >setHosts($Host)->build();
}

public function execute($verb, $params)
{
    switch ($verb) {
    case "create":
        $response = $client->index($params);
        break;
    case "read":
        $response = $client->get($params);
        break;
    case "search":
        $response = $client->search($params);
        break;
    case "delete":
        $response = $client->delete($params);
        break;
    }
}
}

和我得到的错误:

Fatal error: Class 'AppBundle\ElasticsearchQuery\Elasticsearch\ClientBuilder' not found

我不希望它在我的AppBundle中寻找Elasticsearch，我希望它在供应商中寻找它。
我怎么做？

编辑:使用 使用\ Elasticsearch \ ClientBuilder; 或 Elasticsearch \ ClientBuilder::create()没什么区别

Answer 1

$this->client = Elasticsearch\ClientBuilder::create()

这应该是

$this->client = \Elasticsearch\ClientBuilder::create()

或(因为您已经将该类导入了您的 namespace )

$this->client = ClientBuilder::create()
