Lumen Container.php正在尝试构建它不支持的类'；不必

我目前正在使用Lumen来构建API，同时也在玩弹性搜索。我与一家服务提供商建立了一个名为GeocodeService的服务，该服务提供商目前正在构建弹性搜索客户端，并将其注入GeocodeService。这些类的代码如下所示

GeocodeService.php

<?php
namespace App\Services;

use App\Models\ElasticSearch\Geocode;
use Elasticsearch\Client;

class GeocodeService
{
    protected $client;

    public function __construct(
        Client $client
    )
    {
        $this->client = $client;
    }
}

如果我在GeocodeService类的构造函数的第一行调用dd（$client），那么我将获得客户机对象的输出，并且没有错误

所以我的问题是，有人知道这个问题的根源吗？如果我能做些什么来防止它

如果你需要任何进一步的信息，请告诉我

提前感谢您的回复

您可以将

Elasticsearch\Client

的实现绑定到容器中。类似于（在您的服务提供商中）：

使用

Container:：make

方法：

$geocodeService = app(App\Services\GeocodeService::class);

// or
$geocodeService = app()->make(App\Services\Geocode::class);

// or via Facade
// make sure you have uncommented '$app->withFacades()' in
// bootstrap/app.php file
$geocodeService = App::make(App\Services\Geocode::class);

嘿，我也遇到了这个问题：我的代码像$this->app->bind（'\ElasticSearch\Client'，function（$app）{returnnew\ElasticSearch\Client（）；}）；在我的控制器中输入的客户端。。它试图获得内部传输类。。你知道为什么吗？你试过使用

Elasticsearch\ClientBuilder:：create（）->build（）

而不是

new\Elasticsearch\Client（）

？嗨，克莉桑，谢谢你的快速回复。。我解决了这个问题。。第一件事。。必须按照你说的那样使用建筑商。。第二期我写的是ElasticSearch而不是ElasticSearch所有地方。。坏类型：（…我花了3小时才弄明白.）。。
