[laravel] blog project practical notes - login operation and creation of backend home page

I always want to do a small project by myself, but I don’t know how to start. I always do a certain part of the project when I go to work, and I don’t do a project as a whole. The following is a summary of the videos I watched on the PHP Chinese website Notes for your reference. This is a practical blog project done in a Windows environment.

1. Backend login verification code Crypt encryption and decryption

1) First allocate a route (test)

2) Create a crypt method

Use Crypt::encrypted(); to encrypt the password

$str = '123456';
$str_p='eyJpdiI6IkRKNlZsU2k3OWhtTkxTUTFObWdpaVE9PSIsInZhbHVlIjoiUUVhRTFqd0YwQk1TeDVMU3RuenBodz09IiwibWFjIjoiOTZjZDZlMTJjZmY1NTQwYjA4ZTBiYzhiODVhMjk0NDAxNzI4ZDNlNjM4OWIyYzhkZTIyNmZhMDgxYWE4OWFkMyJ9';
echo Crypt::encrypt($str);  //加密
echo &#39;<br/>&#39;;
echo Crypt::decrypt($str_p);    //解密

3) Determine whether the username and password are correct

$user =BlogUserModel::first();
if($user->user_name !=$input['user_name'] || Crypt::decrypt($user->pass_word) != $input['pass_word']){
return back()-> with('msg','用户名或密码错误！');
}

4) If the username and password are correct, save the information to the session Inside

session(['user'=>$user]);  //将数据存储到session里
dd(session('user'));

2. The layout of the background home page, welcome page, and subviews

1) The content is the same, put it in the common

# of the layouts folder ##Put the glass content into the subview, in the glass content part @yield('content')

2) Reference the template file in the subview

@extends(home.layouts.common)
@section('content')

This is for the subview Glass content

@endsection

3) After successful login, transfer to the backend home page

return redirect() //表示调转每个页面

4) Quote the transfer page address

{{URL::asset('/home/index')}}

5) Introduction of css and js

{{URL::asset('/css/style.css')}}

3. Backstage administrator login middleware settings and logout

1) Log in to this route (does not need to be placed in the group that determines whether to log in)

route::group();
route::group([],function(){
});
route::group(['middleware'=>['web','admin.login']],function(){
});

2) In kernel.php

'admin.login' => \App\Http\Middleware\AdminLogin::class Register a middleware

3) Use PHP artisan to create middleware

 php artisan make:middleware AdminLogin

4) After successful login, put the information into the session. This is where we get the value in the middleware to see if there is any value.

    if(session('user')==null){
           return redirect('home/login');
       }

5) Log out of the middleware

Assign a reason

public function quit(){
       session(['user'=>null]);
       return redirect('home/login');
   }

6) See that this route not only has a prefix, but also a prefix and namespace

Route::group(['middleware'=>['web','admin.login']],function(){
                   Route::any('home/quit','Home\LoginController@quit');
                   Route::any('home/index','Home\IndexController@index');
                   Route::any('home/article','Home\IndexController@article');
               });

The following is the optimization of the above

Route::group(['middleware'=>['web','admin.login']],'prefix'=>'admin', 'namespace' =>'Admin',function(){
                   Route::any('quit','LoginController@quit');
                   Route::any('index','IndexController@index');
                   Route::any('article','IndexController@article');
               });

The above The steps are my study notes. I wrote down the steps to be performed or the key points. If there is anything I don’t understand, I can leave a message. Thank you everyone for supporting me. I hope it can help Xiaobai. If you want to see more blog project information, follow me and I will share more content with you.
