Laravel5`RouteServiceProvider`应该与`错误兼容

问题描述：

我正在开发Laravel5的Web应用程序，并用Controller的代码编写了下面的代码.

I am developing a web application by Laravel5, and in code of Controller, I wrote a code bellow.

public function show($id)
{
    $post = Post::find($id);
    \View::share(compact('post'));
    return view('posts.show');
}

但是，我想写如下.

public function show(Post $post)
{
    \View::share(compact('post'));
    return view('posts.show');
}

在RouteServiceProvider.php中，我添加了Router $router

public function boot(Router $router)
{

但是，它不起作用，并且在下面显示错误消息.

but, it doesn't work, and I got an error bellow.

声明 App \ Providers \ RouteServiceProvider :: boot(App \ Providers \ Router $ router) 应该与 Illuminate \ Foundation \ Support \ Providers \ RouteServiceProvider :: boot()

Declaration of App\Providers\RouteServiceProvider::boot(App\Providers\Router $router) should be compatible with Illuminate\Foundation\Support\Providers\RouteServiceProvider::boot()

什么问题? 谢谢！

答

您使用的是哪个laravel版本?

在低于5.3的版本中，您必须编写如下内容.

In version newer than 5.3, you have to write as follows.

public function boot()
{
    //
    parent::boot();
    Route::model('post', \App\Post::class);
}
