如何在 laravel api 中使用护照获取用户 ID？

Question

i am trying to retrieve user ID using auth

what i have tried so far:

public function testfun()
{
    $id = Auth::user()->id;
    return $id;
}

it return:

ErrorException: Attempt to read property "id" on null

i tried:

public function testfun(Request $request)
{
    return Auth::user()->id;
}

i got the same error

i tried to place the API within the middleware:

Route::group(['middleware' => 'auth:api'], function() {
Route::get('testapi', [RegisterController::class, 'testfun']);
});

and call it with guard:

public function testfun(Request $request)
{
    return auth('api')->user();
}

i got:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route [/login] not defined.

here is the full Route of API:

Route::group(['prefix' => 'auth'], function () {
Route::post('login', [RegisterController::class, 'login']);
Route::post('register', [RegisterController::class, 'register']);


Route::group(['middleware' => 'auth:api'], function() {
Route::get('logout', [RegisterController::class, 'logout']);
Route::get('user', [RegisterController::class, 'user']);
Route::post('changePassword', [RegisterController::class, 'changePassword']);
Route::get('testapi', [RegisterController::class, 'testfun']);
});
});

when i place this route under the first group(auth):

Route::get('testapi', [RegisterController::class, 'testfun']);

and try this on controller:

return auth()->user();

i will get response 200 but it doesn't show anything

here is my login function:

public function login(Request $request)
{
    $request->validate([
    'email' => 'required|string|email',
    'password' => 'required|string',
    ]);

    $credentials = request(['email','password']);
    if(!Auth::attempt($credentials))
    {
    return response()->json([
        'message' => 'Unauthorized'
    ],401);
    }

    $user = $request->user();
    $tokenResult = $user->createToken('Personal Access Token');
    $token = $tokenResult->token;

    if($request->remember_me)
        $token->expires_at = Carbon::now()->addWeeks(1);
    $token->save();

    return response()->json([
        'message'=>'Authorized Successfully!',
        'access_token' => $tokenResult-> accessToken,
        'token_type'=> 'Bearer',
        'expires_at'=> Carbon::parse(
            $tokenResult->token->expires_at
        )->toDateTimeString(),
        'userData' => $this->user($request),
    ]);
}

in the above after login i am able to see the user details under 'userData' as showing below from Postman

{
"message": "Authorized Successfully!",
"access_token": "eyJ0eXAiOiJKV1QiLC....",
"token_type": "Bearer",
"expires_at": "2023-12-05 11:18:07",
"userData": {
    "id": 1,
    "fullname": "Admin",
    "email": "admin@gmail.com",
    "roles_id": 2,
    "role": "Admin"
}
}

i even tried to place it alone in the API route as showing below:

Route::middleware('auth:api')->get('/usertest', function (Request $request) {
return $request->user()->id;
});

and i got this error:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route [/login] not defined

i have been trying to get the ID of the authenticated user but with no luck

what am i doing wrong?

Answer:

in Postman i had to set this header Accept: application/json otherwise Laravel Passport would never know it's an API client and thus redirect to a /login page for the web. https://stackoverflow.com/a/51681131/19663907

and also for Authorization in Postman (Bearer Token) placed the token in it after login

and used the function as showing below:

public function testfun(Request $request)
{
    $id = $request->user()->id;
    $currentUser = DB::table('users')
        ->select('users.*')
        ->where('id', $id)
        ->get();

        return $currentUser;
}
