找不到类'GuzzleHttp \ Client'-本地依赖项

Question

我正在编写一个使用GuzzleHttp的库。该库位于composer软件包中：

composer.json

"require": {
    // ...

    "adz/test": "^1.0@dev",

    // ...
}

./ vendor / adz / test / composer.json

 "require": {
     "php": "~5.6|~7.0",
     "guzzlehttp/guzzle": "^6.3"
 },

库控制器

namespace adz\test;

use GuzzleHttp\Client;

class User
{
    static $client;

    public function __construct()
    {
        self::$client = new \GuzzleHttp\Client();
    }

    public static function getAll()
    {
        $res = self::$client->request('GET', 'https://jsonplaceholder.typicode.com/users');
        return $res->getBody();
     }
}

前端控制器

use adz\test\User;

class UserController extends Controller
{
    var $user, $allUsers;

    public function __construct()
    {
        $this->user = new User();
    }

    public function getAll()
    {
        $allUsers = $this->user::getAll();
        echo $allUsers;
    }
}

在运行时，应用程序报告：

  

找不到类'GuzzleHttp \ Client'。

如果我

composer require guzzlehttp/guzzle

在我的composer.json前面，然后Guzzle正常工作。但是我不想将Guzzle加载到前面的composer.json中。

我只想将Guzzle加载到库composer.json文件中。

我该怎么办？

编辑：（./vendor/adz/test/composer.json）-完整版；
