依存性注入が機能しないのはなぜですか？

私は依存性の注入に問題が生じています、私が手にエラーがある：依存性注入が機能しないのはなぜですか？

local.ERROR: exception 'ErrorException' with message 'Argument 1 passed to App\Http\Controllers\APIsController::get_JWT_token() must be an instance of GenTux\Jwt\JwtToken, integer given, called in C:\Bitnami\wappstack-5.6.29-0\apache2\htdocs\testproject\business-web\app\Services\Access\Traits\RegistersUsers.php on line 82 and defined' in C:\Bitnami\wappstack-5.6.29-0\apache2\htdocs\testproject\business-web\app\Http\Controllers\APIsController.php:163

私はAPIsControllerでJwtTokenを含めておりますがよう：

：私のようにメソッドを呼び出して行う

use GenTux\Jwt\GetsJwtToken; 
use GenTux\Jwt\JwtToken; 

use GetsJwtToken; 
// $jwt is not injected 
public function get_JWT_token(JwtToken $jwt, $user_id = null) 
    { 
     if ($user_id == null) { 
      $payload = [ 
       'exp' => time() + (60 * 60 * 24 * 30), 
       'user_id' => Auth::user()->getKey(), 
       'product_name' => env('PRODUCT_NAME') 
      ]; 
     } else { 
      $payload = [ 
       'exp' => time() + (60 * 60 * 24 * 360), 
       'user_id' => $user_id, 
       'product_name' => env('PRODUCT_NAME') 
      ]; 
     } 
     $token = 'Bearer ' . $jwt->createToken($payload); // new instance of JwtToken 
     return $token; 
    }

[設定\ app.php]：プロバイダで：私も、パッケージを登録

$apis = new APIsController(); 
$JWT_token = $apis->get_JWT_token($user->id);

GenTux\Jwt\Support\LaravelServiceProvider::class,

なぜ、依存性注入は機能しませんでしたか？

エラーが

$JWT_token = $apis->get_JWT_token($user->id);

あなたは確かにある第一引数として整数を与えている、ここで

Argument 1 passed to App\Http\Controllers\APIsController::get_JWT_token() must be an instance of GenTux\Jwt\JwtToken, integer given

次のとおりです。ここで

は、完全なスタックトレースであります $user->id

代わりに提供する必要があります

GenTux\Jwt\JwtToken

インスタンスです。

- 編集後@ user7409342のinput--

あなたはこの

public function get_JWT_token($user_id = null) 
{ 
    $jwt = app(JwtToken::class); // Resolve JwtToken using app() 
    if ($user_id == null) { 
     $payload = [ 
      'exp' => time() + (60 * 60 * 24 * 30), 
      'user_id' => Auth::user()->getKey(), 
      'product_name' => env('PRODUCT_NAME')

    } else { 
     $payload = [

    }

私がいることを理解し、私はトラブルオブジェクトをインスタンス化が生じています。それらは必要なパラメータですが、私はオブジェクトをインスタンス化するときにそれぞれのために何を置くべきかわかりません。 – WingsOfAltair

@ user7409342あなたの入力で自分の答えを変更しました – Gayan

投稿した内容と一致するようにメソッドを編集した後にこのエラーが発生しました。エラー：定義されていない定数JwtTokenの使用 - 'JwtToken'を仮定我々は一歩近づいています、紳士！ – WingsOfAltair

$ JWT_token = $ apis-> get_JWT_token（する$ user-> id）を行うことができます。

ここでは、最初の引数をuser_idおよびget_JWT_token関数として渡しています。最初の引数は、問題を引き起こしているJwtTokenオブジェクトであり、以下のような関数の定義を変更します。

パブリック関数get_JWT_token（JwtToken $ JWT、$ USER_ID = NULL）{ ... //あなたのコード }
