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

Question

用户登录时，设置了session('person_id')，但Auth::user()返回null

这意味着我必须在任何需要访问用户的属性或方法的地方这样做:

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

有什么更好的解决方案?我可以在BaseController中设置$person，然后在需要时通过$this->user访问用户吗?

我不想为每个页面上的每个请求做一个DB查询。

以下是我当前的登录和注册功能:

/**
* Handles user login
*
* @param  Request $request
* @return IlluminateHttpRedirectResponse
*/
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');
}

似乎你的战斗与框架默认身份验证你使用另一个模型而不是用户我建议阅读官方文档您可以查看larravel breeze，了解它们是如何实现身份验证的如果您检查laravel breeze，您会发现您错过了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', RulesPassword::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);
}

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