Laravel Proteksi Route

Laravel proteksi route dengan middleware.

Route::prefix('admin')->middleware('auth')->group(function (){

 Route::get('/mahasiswa', 'MahasiswaController@index');
 Route::get('/mahasiswa/tambah/', 'MahasiswaController@tambah');
 Route::post('/mahasiswa/simpan/', 'MahasiswaController@simpan');
 Route::get('/mahasiswa/ubah/{id}', 'MahasiswaController@ubah');
 Route::put('/mahasiswa/simpanubah/{id}', 'MahasiswaController@simpanubah'); 
 Route::delete('/mahasiswa/hapus/{id}', 'MahasiswaController@hapus'); 
 Route::get('/mahasiswa/hapusmudah/{id}', 'MahasiswaController@hapus'); 
});
