【问题标题】：how to create a token in laravel tymons/jwt-auth如何在 laravel tymons/jwt-auth 中创建令牌

【问题描述】：

我想创建一个使用用户角色编码的令牌。我试过查看文档，但我没有得到令牌。我已经尝试过。

我使用的是 laravel 5.8 和包版本 "tymon/jwt-auth": "^1.0.0-rc.2"

谢谢

授权控制器

 public function login()
    {
        $credentials = request(['email', 'password']);

        if (! $token = auth()->guard('api')->attempt($credentials)) {
            return response()->json(['errors' => 'In-valid username and Password'], 401);
        }

        $customClaims =[
           'role' => auth('api')->user()->getRoleNames()
        ];
        $payload = JWTFactory::make($customClaims); 
        $token = JWTAuth::encode($payload);

        return $this->respondWithToken($token);
    }

  protected function respondWithToken($token)
    {
        return response()->json([  
            'success' => true, 
            'access_token' => $token,
            'token_type' => 'bearer',
        ]);
    }

【解决方案1】：

你的用户模型应该是这样的

class User extends Authenticatable implements JWTSubject
{
    use Notifiable, HasRoles;

    public function getJWTIdentifier()
    {
        return $this->getKey();
    }
    public function getJWTCustomClaims()
    {
        return [];
    }


}

public function login()
    {
        $credentials = request(['email', 'password']);

        if (!$token = JWTAuth::attempt($credentials)) {
            return response()->json(['errors' => 'In-valid username and Password'], 401);
        }

        $customClaims =[
           'role' => auth('api')->user()->getRoleNames()
        ];
        $payload = JWTFactory::make($customClaims); 
        $token = JWTAuth::encode($payload);

        return $this->respondWithToken($token);
    }

【解决方案2】：

基于documentation，您可能需要执行两次attempt()，如下所示：

public function login()
{
    $credentials = request(['email', 'password']);

    if (!auth()->guard('api')->claims(['role' => 'bar'])->attempt($credentials)) {
        return response()->json(['errors' => 'In-valid username and Password'], 401);
    }

    $token = auth('api')->claims(['role' => auth('api')->user()->getRoleNames()])->attempt($credentials);

    return $this->respondWithToken($token);
}

我正在获取令牌
非常感谢，我有一个疑问如何解码和检查令牌？我是否得到了这个角色？
@matheenulla 查看this。您应该能够使用auth('api')->payload() 查看有效负载

【解决方案3】：

试试这个

use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;

class AuthenticateController extends Controller
{
    public function login(Request $request)
    {
        // grab credentials from the request
        $credentials = $request->only('email', 'password');

        try {
            // attempt to verify the credentials and create a token for the user
            if (!auth()->guard('api')->claims(['role' => 'bar'])->attempt($credentials)) 
                {
                 return response()->json(['errors' => 'In-valid username and Password'], 401);
                }

             $token = auth('api')->claims(['role' => auth('api')->user()->getRoleNames()])->attempt($credentials);

             return $this->respondWithToken($token);
        } catch (JWTException $e) {
            // something went wrong whilst attempting to encode the token
             return response()->json(['error' => 'could_not_create_token'], 500);
        }

        // all good so return the token
         return response()->json(compact('token'));
    }
}
