Laravel 8 浅谈
逑俊楚
最近PHP 版本升级了7.4，之后用composer下载 Laravel，发现已经更新到8了，然后就试下看着文档操作，看看有啥不一样！
官方文档重点说了Laravel Jetstream，这是一个UI 的脚手架。一般情况下，如果我需要写前端，我会单独分开写的，不会用到Laravel 的脚手架，包括那个资源整合Mix，也不用，所以这个更新其实对我影响不大！忽略
写法上，暂时发现有些地方有变化
路由：
以前写法：
Route::get('/', 'HomeController@index')->name('home');现在写法：
use App\Http\Controllers\FrontController;
Route::get('/front', [FrontController::class, 'index']);路由中需要引入 Controller 的路径
Models:
Laravel 8 终于在 app 目录下引入了 Models 子目录来存放模型类文件，所有通过 make:model 命令生成的模型类以后默认都会存放在这个目录下；不过，如果你选择删除这个目录，新生成的模型类将仍然存放到 app 目录下。
app/View:
Laravel8 的app里面有个View 文件夹，里面有个Components的文件夹，上面查了一下，是Blade View Components （组件和插槽），以后有空再写个案例，简单点说，就是将view模块化，有点像Vue。
用户验证
因为懒，所以我经常用 laravel 的自带的登录模块来改，这个和以前版本的有点区别，因为用了jetstream，所以新增了一些写法。
composer require laravel/jetstream
// 使用 Livewire 栈安装 Jetstream...
php artisan jetstream:install livewire
// 使用 Inertia 栈安装 Jetstream...
php artisan jetstream:install inertia
路由就多了一句
Route::middleware(['auth:sanctum', 'verified'])->get(........在检查一下路由list，就发现多了很多条路由

| | | | | | Illuminate\Auth\Middleware\RequirePassword其中可以发现login post 对应的 Controller是 Laravel\Fortify\Http\Controllers\AuthenticatedSessionController@store
打开检查这个方法：
/**
* Attempt to authenticate a new session.
*
* @param \Laravel\Fortify\Http\Requests\LoginRequest $request
* @return mixed
*/
public function store(LoginRequest $request)
{
return $this->loginPipeline($request)->then(function ($request) {
return app(LoginResponse::class);
});
}
/**
* Get the authentication pipeline instance.
*
* @param \Laravel\Fortify\Http\Requests\LoginRequest $request
* @return \Illuminate\Pipeline\Pipeline
*/
protected function loginPipeline(LoginRequest $request)
{
if (Fortify::$authenticateThroughCallback) {
return (new Pipeline(app()))->send($request)->through(array_filter(
call_user_func(Fortify::$authenticateThroughCallback, $request)
));
}
if (is_array(config('fortify.pipelines.login'))) {
return (new Pipeline(app()))->send($request)->through(array_filter(
config('fortify.pipelines.login')
));
}
return (new Pipeline(app()))->send($request)->through(array_filter([
config('fortify.limiters.login') ? null : EnsureLoginIsNotThrottled::class,
Features::enabled(Features::twoFactorAuthentication()) ? RedirectIfTwoFactorAuthenticatable::class : null,
AttemptToAuthenticate::class,
PrepareAuthenticatedSession::class,
]));
}这个和以前的使用 登录方法已经不同了，以前的登录方法是这样：
$credentials = $request->only('email', 'password');
if (Auth::attempt($credentials)) {
$request->session()->regenerate();
return redirect()->intended('home');
}
return back()->withErrors([
'email' => 'The provided credentials do not match our records.',
]);为此，我用了以前的登录方法测试下，其实还是可以用的！其他使用基本不变！应该是因为使用了jetstream。
暂时发现这些！真正到项目开发的时候就会发现更多！加油！
