how to protect api laravel code example

Example 1: laravel 7 user registration using api post endpoint

<?php

namespace App\Http\Controllers;


use Illuminate\Http\Request;
use App\User;

class AuthController extends Controller
{
    public $loginAfterSignUp = true;

    public function register(Request $request)
    {
      $user = User::create([
        'name' => $request->name,
        'email' => $request->email,
        'password' => bcrypt($request->password),
      ]);

      $token = auth()->login($user);

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

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

      if (!$token = auth()->attempt($credentials)) {
        return response()->json(['error' => 'Unauthorized'], 401);
      }

      return $this->respondWithToken($token);
    }
    public function getAuthUser(Request $request)
    {
        return response()->json(auth()->user());
    }
    public function logout()
    {
        auth()->logout();
        return response()->json(['message'=>'Successfully logged out']);
    }
    protected function respondWithToken($token)
    {
      return response()->json([
        'access_token' => $token,
        'token_type' => 'bearer',
        'expires_in' => auth()->factory()->getTTL() * 60
      ]);
    }

}

Example 2: laravel token authentication

# Database Preparation
// add api_token to users table
Schema::table('users', function ($table) {
    $table->string('api_token', 80)->after('password')
                        ->unique()
                        ->nullable()
                        ->default(null);
});

// Create token for existing users, code can also be added to registerController
    $token = Str::random(60);
    $user = User::find(1);
    $user->api_token = hash('sha256', $token); // <- This will be used in client access
    $user->save();



//config/auth.php
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token', // <- Add this entry
            'provider' => 'users',
            'hash' => false,
        ],
    ],

          
          
//routes/api.php
    // Add "middleware('auth:api')" as below        
	Route::middleware('auth:api')->get('/user', function (Request $request) {
        return $request->user();
    });          



//client access example (in Vue js)

axios.get('http://example.com/api/user', 
          {
  headers: { 
    'Accept': 'application/json', 
    'Authorization': 'Bearer '+ 'user-api-token'
  }
}
         )
  .then(function (response) {
  // handle success
  console.log(response);
})
  .catch(function (error) {
  // handle error
  console.log(error);
})
