如何在Laravel 5.1中使用哈希类登录

Question

I want use hash class for hash my passwords.
because I want slat password with My policy.
I have controller like this:

 public function postLogin(Request $request)
{
   $rules = array(
        'username' => 'required',
        'password' => 'required|min:8'
    );
    $validator = Validator::make($request->all(), $rules);
    if ($validator->fails()) {
        return redirect()->back()->withErrors($validator)
            ->withInput();
    } else {
        $user=User::where('username',$request['username'])->where('group_id',1)->get()->toArray();
        $password=new PasswordController;
        $request['password'] = $password->create_password_str($request['username'],$request['password']);
       if(isset($user[0]['password'])&&Hash::check($request['password'], $user[0]['password'])){
            return redirect('/dashboard');
        } else {
            return view('auth.login')->with('flag',5);
        }
    }
}

I use username after login like this

{{Auth::user()->username}}

show me error

Trying to get property of non-object

I add this code before redirect but dont work.

  Auth::login($request['username']);

Because you do not use the laravel builtin function so it did not store the user in a SESSION and it throws an error while you try to fetch a user data which actually does not exists. Here's how to authenticate with laravel auth attempt function

if( Auth::attempt(['username' => $username, 'password' => $password]))
{
   //redirect to dashboard
} else
{
  //invalid credentials
}

Even you do not need to convert your password to hash. laravel is intelligent enough to convert it to hash.

If you want to use custom salt for your project you could checkout this link .
