You can get it like this
你可以这样得到
$request->route('id')
Inside request class you can access it this way
在请求类中，您可以通过这种方式访问它
$this->route('id')
I usually use it when I'm validating field to make sure it's unique, and I need to exclude model by ID when I'm doing update
我通常在验证字段时使用它以确保它是唯一的，并且在我进行更新时需要按 ID 排除模型

This is because you're passing the id parameter through url, you should send it using a form like this
这是因为您通过 url 传递 id 参数，您应该使用这样的表单发送它
{!! Form::open(['route'=>' route('message.inbox.detail.id', 'method'=> 'POST']) !!}
<input type="hidden" name="id" value="{{ $message->id }}" />
{!! Form::submit({{ trans('button.view') }}, ['class'=>'btn btn-default']) !!}
{!! Form::close() !!}
and now you can access via request in your controller
现在您可以通过控制器中的请求访问
public function detail(Request $request)
{
dd($request->input('id'));
}

Get the id via this:

public function detail($id)
{
dd($id);
}
