laravel二日学有问题及时指出写出来为了方便他人也提炼自己所学还望指点

PHP

laravel 安装：
composer down 下来首先确定 php是否在计算机的环境变量里其次在确定composer是否在环境变量里这关乎你能不能实行这种方法
cd到你的本地环境根目录运行 composer global require "laravel/installer"
包down了之后可以用 laravel new app-name (文件夹名字)
也可以用 composer来创建（当前一种不行的时候用这种或者直接用这种） composer create-project laravel/laravel --prefer-dist blog
创建过后打开命令行或者cmd 敲上php artisan serve 就可以访问了
路由：
路由是一个项目的根基 laravel的路由相比其他的框架（接触的不多）他的路由不同他的路由是由 App\Providers\RouteServiceProvider 这个类载入的一个路由群组（就是一个很多单个路由在一起），接受到参数然后进入指定的控制器方法这个路由文件放在哪呢 app\http\route.php
当然这种参数接受方法可以很多样可以指定可以匹配只要你会玩能玩好都可以这路由会有一些中间件提供一些session的状态和crsf的保护举个栗子：
Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);
如何注册你自己想要的路由呢看下面
Route::get('home/index', ['as'=>'index','uses'=>'indexController@home']);
接受到home/index 后将跳到index控制器下的home方法下去 as指定路由名称 use 指定控制器与方法名用@符间隔
插一个中间件的概念中间件是laravel 为过滤进入应用的 HTTP 请求提供了一套便利的机制包含权限控制，认证，表单验证（crsf）等等一些中间件

控制器：
控制器存放如app\Http\Controllers 下可以通过PHP artisan make:Controler name(控制器名) 没什么特殊情况就用这个为什么便利

    创建自己的方法 创建控制器后 干嘛呢 渲染模板啊 对吧 上面 就有 view方法 第一个是文件位置 文件放哪呢 文件放在resource\views 可以自己建文件夹 很自由大胆建
    laravel 的模板引擎是blade引擎 所以自己创建的时候 记得加blade

视图层：
视图层的主要就是上面所说的blade模板引擎先说接受PHP传过来的数据吧就是上面那个name 可以用{{ $name }} 接收说完简单的变量接受如果我们是一个数组的话怎么办叻
循环@foreach($a as $b) @endforeach @for( $i=1;$i<5;$i++) @endfor 不一一列举懂就好判断@if (count($records) === 1) @endif
最后一个包布局包样式这个东西是常见的东西先说布局
我在views下创建一个layout文件夹放一个top_layout.blade.php
代码如下：
<html>
<head>
<title>HomePage - @yield('title')</title>
</head>
<body>
@section('sidebar')
This is the master sidebar.
@show

    <div class="demo">
        @yield('content') <!-- 展示子视图指定section的位置 -->
    </div>
</body>

</html>
然后有views\home\home.blade.php文件代码：
@extends('layouts.home.top_layout')
@section('title', 'Mr.Knowledgeable')
@section('sidebar')
@parent
<p>This is appended to the {{$name}} sidebar.</p>
@endsection
@section('content')
@foreach($list as $users)
<p>This is user {{ $users->member_name }}</p>
@endforeach
@endsection
这样差不多凑合用那我想在引用点js css 啊怎么办 5 之前是可以直接用这个html方法的现在没了就要composer了
composer require illuminate/html 5.*
包down下来之后在你的 config/app.php
注册服务提供者到 providers 数组
（至于有些说还要加这个我想说的是我的5.2的加了这行后框架会起不来暂时还不知道什么原因所以我注释了他一样的用如果有知道可以告诉我）
'providers' => [

    /*
     * Laravel Framework Service Providers...
     */
    Illuminate\Auth\AuthServiceProvider::class,
    Illuminate\Broadcasting\BroadcastServiceProvider::class,
    Illuminate\Bus\BusServiceProvider::class,
    Illuminate\Cache\CacheServiceProvider::class,
    Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class,
    Illuminate\Cookie\CookieServiceProvider::class,
    Illuminate\Database\DatabaseServiceProvider::class,
    Illuminate\Encryption\EncryptionServiceProvider::class,
    Illuminate\Filesystem\FilesystemServiceProvider::class,
    Illuminate\Foundation\Providers\FoundationServiceProvider::class,
    Illuminate\Hashing\HashServiceProvider::class,
    Illuminate\Mail\MailServiceProvider::class,
    Illuminate\Pagination\PaginationServiceProvider::class,
    Illuminate\Pipeline\PipelineServiceProvider::class,
    Illuminate\Queue\QueueServiceProvider::class,
    Illuminate\Redis\RedisServiceProvider::class,
    Illuminate\Auth\Passwords\PasswordResetServiceProvider::class,
    Illuminate\Session\SessionServiceProvider::class,
    Illuminate\Translation\TranslationServiceProvider::class,
    Illuminate\Validation\ValidationServiceProvider::class,
    Illuminate\View\ViewServiceProvider::class,
    //Illuminate\Html\HtmlServiceProvider::class,

    /*
     * Application Service Providers...
     */
    App\Providers\AppServiceProvider::class,
    App\Providers\AuthServiceProvider::class,
    App\Providers\EventServiceProvider::class,
    App\Providers\RouteServiceProvider::class,

],

注册门面到 aliases 数组
'aliases' => [

    'App' => Illuminate\Support\Facades\App::class,
    'Artisan' => Illuminate\Support\Facades\Artisan::class,
    'Auth' => Illuminate\Support\Facades\Auth::class,
    'Blade' => Illuminate\Support\Facades\Blade::class,
    'Cache' => Illuminate\Support\Facades\Cache::class,
    'Config' => Illuminate\Support\Facades\Config::class,
    'Cookie' => Illuminate\Support\Facades\Cookie::class,
    'Crypt' => Illuminate\Support\Facades\Crypt::class,
    'DB' => Illuminate\Support\Facades\DB::class,
    'Eloquent' => Illuminate\Database\Eloquent\Model::class,
    'Event' => Illuminate\Support\Facades\Event::class,
    'File' => Illuminate\Support\Facades\File::class,
    'Gate' => Illuminate\Support\Facades\Gate::class,
    'Hash' => Illuminate\Support\Facades\Hash::class,
    'Lang' => Illuminate\Support\Facades\Lang::class,
    'Log' => Illuminate\Support\Facades\Log::class,
    'Mail' => Illuminate\Support\Facades\Mail::class,
    'Password' => Illuminate\Support\Facades\Password::class,
    'Queue' => Illuminate\Support\Facades\Queue::class,
    'Redirect' => Illuminate\Support\Facades\Redirect::class,
    'Redis' => Illuminate\Support\Facades\Redis::class,
    'Request' => Illuminate\Support\Facades\Request::class,
    'Response' => Illuminate\Support\Facades\Response::class,
    'Route' => Illuminate\Support\Facades\Route::class,
    'Schema' => Illuminate\Support\Facades\Schema::class,
    'Session' => Illuminate\Support\Facades\Session::class,
    'Storage' => Illuminate\Support\Facades\Storage::class,
    'URL' => Illuminate\Support\Facades\URL::class,
    'Validator' => Illuminate\Support\Facades\Validator::class,
    'View' => Illuminate\Support\Facades\View::class,
    'Html' => Illuminate\Html\HtmlFacade::class,
    'Form' => Illuminate\Html\FormFacade::class,

],

然后在把你想引用的文件放在public下是css 就叫css js就js whatever you like
使用方法：
1>
{!!Html::style('css/style.css')!!}
{!!Html::script('js/script.js')!!}
{!!Html::style('//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css')!!}
{!!Html::script('//code.angularjs.org/1.2.13/angular.js')!!}
2>
<link rel="stylesheet" href="{{ URL::asset('//netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css') }}">
<link rel="stylesheet" href="{{ URL::asset('css/bootstrap.css') }}"><script type="text/javascript" class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="{{ URL::asset('js/jquery.min.js') }}"></script>
