Php LaravelSOAP服务器&；客户端：不允许使用此方法

我尝试为Laravel Framework 5.5.13设置一个SOAP服务器。因此，我创建了两个类（Server.php和Client.php）和两个控制器，SoapServerController和SoapClientController

以下是源代码：

app/Classes/Soap/Server.php

namespace App\Classes\Soap;

class Server {
    public function __construct() {
    }

    public function getDate() {
        return date('Y-m-d');
    }

}

app/Classes/Soap/Client.php

namespace App\Classes\Soap;

class Client {

    protected $instance;

    public function __construct() {
        $params = array( 'uri' => '/soap/server',
                         'location' => url('/soap/server'),
                         'trace' => 1,
                         'soap_version' => SOAP_1_2
                         );

        $this->instance = new \SoapClient( null, $params );

    }

    public function getDate() {
        return $this->instance->getDate();
    }

}

app/Http/Controllers/SoapServerController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Classes\Soap;

class SoapServerController extends Controller
{
    public function index() {
        $params = array( 'uri' => url('/soap/server') );
        $server = new \SoapServer( null, $params );
        $server->setClass( Soap\Server::class );
        $server->handle();
    }

}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Classes\Soap;

class SoapClientController extends Controller
{
    public function index() {
        $client = new Soap\Client;
        $client->getDate();
    }
}

app/Http/Controllers/SoapClientController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Classes\Soap;

class SoapServerController extends Controller
{
    public function index() {
        $params = array( 'uri' => url('/soap/server') );
        $server = new \SoapServer( null, $params );
        $server->setClass( Soap\Server::class );
        $server->handle();
    }

}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Classes\Soap;

class SoapClientController extends Controller
{
    public function index() {
        $client = new Soap\Client;
        $client->getDate();
    }
}

当我打开route/api/soap/client时，我得到一个错误：

SoapFault:不允许使用方法

我是否必须更改路由文件中的某些内容？

需要注意的是，SOAP调用都应该在POST请求中执行。最有可能的情况是，您只使用GET请求设置了路由，因此不允许使用方法（POST）
