如何在Laravel中全局访问当前登录的用户，Auth:：user（）返回null

Question

当用户登录时，会话（'person_id'）被设置，但是Auth::user（）返回null。

这意味着我必须在需要访问用户的属性或方法的任何地方这样做：

$person  = Person::where('id', session('person_id'))->firstOrFail();

有什么更好的解决方案？我是否可以在BaseController中设置$person，然后通过$this访问用户-

我不想为每个页面上的每个请求做数据库查询。使用Laravel 8和PHP 8。

以下是我当前的登录和注册功能：

 /**
 * Handles user login
 *
 * @param  Request $request
 * @return \Illuminate\Http\RedirectResponse
 */
public function login(Request $request)
{
    $credentials = $request->validate([
        'email'    => ['required', 'email'],
        'password' => ['required'],
    ]);

    if (Auth::attempt($credentials, request('remember'))) {
        $request->session()->regenerate();

        return redirect()->intended('/account')->with('status', 'Logged in');
    }

    return back()->withErrors([
        'email' => 'The provided credentials do not match our records.',
    ]);
}

/**
 * Saves a new unverified user, sends code to their email and redirects to verify page
 *
 * @param  Request $request
 */
public function signUp(Request $request)
{
    // @todo Move to SignUpRequest file
    $request->validate([
        'email'    => 'required|email|unique:people',
        'password' => 'required',
    ]);

    $person           = new Person; 
    $person->email    = $request->email;
    $person->password = Hash::make($request->password);

    if (!$person->save()) {
        return back()->with('status', 'Failed to save the person to the database');
    }

    $request->session()->put('person_id', $person->id);

    $verification             = new Verification;
    $verification->person_id  = $person->id;
    $verification->code       = rand(111111, 999999);
    $verification->valid_from = Carbon::now();
    $verification->expires_at = Carbon::now()->addDay();

    if (!$verification->save()) {
        return back()->with('status', 'Failed to save the verification to the database');
    }

    // email stuff
    
    return redirect('/verify')->with('status', 'Successfully created account, please verify to continue');
}

Laravel附带全局助手auth（），您可以使用auth（）访问登录用户-

Answer 2

你似乎在与框架默认身份验证作斗争你使用的是另一个模型，而不是用户我建议你阅读官方文档你可以看看laravel breeze，看看他们是如何实现身份验证的如果你检查laravel breeze，你会发现你错过了Auth:：login（$User）

 public function store(Request $request)
    {
        $request->validate([
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'confirmed', Rules\Password::defaults()],
        ]);

        $user = User::create([
            'name' => $request->name,
            'email' => $request->email,
            'password' => Hash::make($request->password),
        ]);

        event(new Registered($user));

        Auth::login($user);

        return redirect(RouteServiceProvider::HOME);
    }
