为什么依赖注入不起作用？

我有在依赖注入的问题，我得到的错误是：为什么依赖注入不起作用？

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

虽然我包括JwtToken在APIsController为：

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; 
    }

我做的调用方法为：

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

我还注册包为： [配置\ app.php]： 在提供商：

GenTux\Jwt\Support\LaravelServiceProvider::class,

那么，为什么依赖注入不起作用？

的错误是

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

在这里

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

你的确给人一种整数作为第一个参数，这是$user->id

相反，您应该提供

GenTux\Jwt\JwtToken

实例。

- 编辑后@ user7409342的input--

你能做到这一点

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 = [ 
      '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; 
}

我明白，但我无法实例化对象。这些是需要的参数，但我不确定在实例化对象时要为每个参数放置什么。公共职能__construct（JwtDriverInterface $智威汤逊，$秘密= NULL，$算法= NULL） – WingsOfAltair

@ user7409342我修改我的回答与你输入 – Gayan

后，我编辑，以匹配你贴什么方法我收到此错误。错误：使用未定义的常量JwtToken - 假定为'JwtToken'。我们离先生们又近了一步！ – WingsOfAltair

0

$ JWT_token = $ apis-> get_JWT_token（$用户> ID）;

这里要传递的第一个参数为USER_ID和get_JWT_token函数第一个参数是多数民众赞成使得问题，所以改变的函数定义像下面的JwtToken对象。

公共职能get_JWT_token（JwtToken $智威汤逊，$ USER_ID = NULL）{ ... //你的代码 }
