Request請求

使用的是symfony/http-foundation組件

存放$_get,$_post,$_cookie,$_files,$_server等數據

Public function request(Request $request)

{

?????????? 取單一get值，可加默認值

?????????? Ehco $request->input(‘name’,‘未知’);

?

?????????? 判斷是否有這個數據

?????????? if($request->has(‘name’’)){

?????????? ???????? ehco $request->input(‘name’, ‘未知’);

?????????? } else {

?????????? ???????? echo ‘null’;

?????????? }

?????????? 取所有參數

?????????? $res = $request->all();

?????????? dd($res)

?

?????????? 判斷請求類型

?????????? 獲取類型

?????????? $res = $request->method();

?????????? 判斷類型

?????????? if($request->isMethod(‘POST’))

?????????? else

?

?????????? 判斷是否為ajax方法

?????????? res = $request->ajax();

?????????? var_dump($res);

?

?????????? 請求的路徑是否滿足特定的格式

?????????? 判斷是否在哪個controllers下某個方法

?????????? $res =$request->is(‘student/*’)

?

?????????? 當前URL

?????????? echo $request->url()

}

?

?

?

?

?

?

Session

Public function request(Request $request)

{

?????????????????? HTTP request 類的session（）方法

???????? $request->session()->put(‘key1’, ‘value’);

?????????? $request->session()->get(‘key1’);

?

?

?????????????????? Session()輔助函數

?????????? Session()->put(‘key1’,‘value’);

?????????? Session()->get(‘key1’);

?

?

???????? ???????? Sessionfa?ade

???????? Session::put(‘key1’, ‘value’);

?????????? Session::get(‘key1’,‘default’);

?

?????????? 以數組方式存值

?????????? Session::put([‘key’=>’val’]);

?

?????????? 把數據放到session數組中

?????????? Session::push(‘value1’,‘value’);

?

?????????? 取完數據并刪除

?????????? Session::pull(‘value’1);

?

?????????? 取出所有數據

?????????? Session::all();

?

?????????? 判斷session中KEY是否存在

?????????? Session::has(‘key’);

?

?????????? 刪除session中KEY

?????????? Session::forget(‘key’);

?

?????????? 刪除session所有KEY

?????????? Session::flush(‘key’);

?

?????????? 臨時數據(第一次訪問有，第二次即空)

?????????? Session::flash(‘key’);

???????? }

?

?

Response響應

常見類型

字符串

?

視圖

?

Json

return Response()->json($data);

?

重定向

路由名字

return Redirect(‘session2’)->with(‘message’,‘這是傳輸的參數’); // session2路由名字

?

action()

return redirect()->action(‘StudentController@update’)->with(‘message’,‘這是傳輸的參數’);

?

路由別名route()

return redirect()->route(‘session’)->with(‘message’,‘這是傳輸的參數’);

?

返回上一級

return redirect()->back();

?

Middelware中間件

1.新建立

<?php

?

namespace App\Http\Middleware;

?

?

class Activity

{

???????? //前置中間件

???public function handle($request, \Closure $next)

??? {

???????if (time() < strtotime('2016-06-05')) {

???????????//跳轉到其他頁

???????????return redirect('active');

???????}

???????return $next($request);

}

?

???????? //后置中間件

???public function handle($request, \Closure $next)

{???????

???????? $response = $next($request);

???????? echo ‘我是后置操作，請往下寫邏輯哦’

??? }

?

}

?

2.Kernel.php下

???/**

????* The application's route middleware.

????*

????* These middleware may be assigned to groups or used individually.

????*

????* @var array

????*/

???protected $routeMiddleware = [

???????'auth' => \Illuminate\Auth\Middleware\Authenticate::class,

???????'auth.basic' =>\Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

???????'bindings' =>\Illuminate\Routing\Middleware\SubstituteBindings::class,

???????'can' => \Illuminate\Auth\Middleware\Authorize::class,

???????'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,

???????'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

???????'activity' =>\App\Http\Middleware\Activity::class,

];

?

3.路由使用

Route::group(['middleware' =>['activity']], function () {

???????? 以下為需要驗證的方法

???Route::get('student/index', ['uses' => 'StudentController@index']);

???Route::any('student/create', ['uses' => 'StudentController@create']);

});
