laravel route work wrong to direct to views - php

Question

I am a new laraveler, now I work with a problem about laravel. I want the / direct to a anguler index.html. and others route to laravel controller. but when the \ direct well . the others routes work wrong to a views directory.
the \app\Http\route.php like follows :
Route::get('/',function(){
return File::get(public_path().('/views/index.html'));
});
Route::get('scan', "userController#Scan");
Route::get('check', "userController#Check");
Route::get('login', "userController#Login");
the directy is something like follows:
├── app
│ ├── Http
│ │ ├── route.php //route file
│ ├── Library
│ ├── Providers
│ ├── Services
│ ├── User.php
│ └── views
│ │ ├── Index.php // php index file , the entry for nginx server
│ └── ..........
├── bootstrap
│ ├── app.php
│ ├── autoload.php
│ └── cache
├── config
│ ├── app.php
│ └── view.php
│ └── ..........
├── public
│ ├── bower_components
│ ├── css
│ ├── data
│ ├── index.bak
│ ├── index.html //angular index file
│ └── scripts
│ └── ..........
now when I access to http://hostname/scan it comes 404 no found.
and the log like follows:
```
*2221 open() "/service/angular-laravel/app/views/scan" failed (2: No such file or directory), client: x.x.x.x, server: hostname, request: "GET /scan HTTP/1.1", host: "banliyun.com:8081"
```
as I was a little confuse with how the route work. can someone tell me why it will route to /views directory where place the laravel index page.

Answer 1

Save your index.html as index.blade.php in /resources/views/index.blade.php and you change your route to the following code:
Route::get('/', function(){
return view('index');
});

Answer 2

In AppServiceProvider class boot method add below line:
View::addLocation(public_path('views'));
Rename index.html file as index.blade.php and then follow below line in your route.php
Route::get('/', function(){
return view('index');
});
