在 Laravel 中，我有一個子類（為了清晰起見，代碼已縮短）：
<?php
namespace App\Http\Controllers\Auth;
class RegisterController extends Controller {
...
protected function create(array $data)
{
$twilio = new Client($this->sid, $this->authToken);
$user = $twilio->chat->v2->services(env("TWILIO_CHAT_SERVICE_SID"))
->users
->create($data['username']);
}
...
}
我有父類：
<?php
namespace App\Http\Controllers;
use Illuminate\Routing\Controller as BaseController;
class Controller extends BaseController
{
public $sid;
public $authToken;
public $serviceId;
public function __construct()
{
$this->sid = getenv("TWILIO_ACCOUNT_SID");
$this->authToken = getenv("TWILIO_AUTH_TOKEN", true);
$this->serviceId = getenv("TWILIO_CHAT_SERVICE_SID");
}
}
盡管如此，我還是收到了這個錯誤：
"message": "Argument 1 passed to Twilio\\Rest\\Chat\\V2\\ServiceList::getContext() must be of the type string, null given, called in /home/fingxtbh/thisnthat.com/vendor/twilio/sdk/src/Twilio/Rest/Chat/V2.php on line 80",
"exception": "TypeError",
"file": "/home/fingxtbh/thisnthat.com/vendor/twilio/sdk/src/Twilio/Rest/Chat/V2/ServiceList.php",
"line": 131,
"trace": [

"type": "->"
},
{
"file": "/home/fingxtbh/thisnthat.com/app/Http/Controllers/Auth/RegisterController.php",
"line": 104,
為什么不能從父類正確讀取變數 $this->serviceId？
uj5u.com熱心網友回復：
env 呼叫不應該是這樣的嗎？
public function __construct()
{
parent::__construct();
$this->sid = env("TWILIO_ACCOUNT_SID");
$this->authToken = env("TWILIO_AUTH_TOKEN", true);
$this->serviceId = env("TWILIO_CHAT_SERVICE_SID");
}
