php-无法在laravel 5.6控制器中创建Request对象
作者:互联网
控制器名称MyController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class MyController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index(){
//
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create(){
//
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request){
//
$request->session()->put('key', '123');
$data = $request->session()->get('key');
print_r($data);
}
/**
* Display the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function show($id){
//
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function edit($id){
//
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return \Illuminate\Http\Response
*/
public function update(Request $request, $id){
//
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function destroy($id){
//
}
public function contact(){
return view('contact');
}
public function createSession(Request $request){
//
$request->session()->put('key', '123');
$data = $request->session()->get('key');
print_r($data);
}
public function viewSession_v1(Request $request){
$data = $request->session()->get('key');
print_r($data);
}
public function viewSession_v2(Request $request){
$data = $request->session()->get('key');
print_r($data);
}
}
路线:
Route::get('createSession', 'MyController@createSession');
Route::get('viewSession-1', 'MyController@viewSession_v1');
Route::get('viewSession-2', 'MyController@viewSession_v2');
现在,当我调用“ createSession”时,它将创建新的会话,当我调用“ viewSession-1”或“ viewSession-2”时,它将显示会话值,但是我想从viewSession_v2()中删除Request $request,所以我执行了以下代码:
public function viewSession_v2(){
$request = new \Illuminate\Http\Request();
$data = $request->session()->get('key');
print_r($data);
}
现在,当我调用“ viewSession-2”时,它将出现以下错误
请任何人告诉我如何在方法/函数中创建请求对象?为什么在这里给我一个错误?
解决方法:
您始终可以访问request()和session()帮助器:
public function viewSession_v2(){
$data = request()->session()->get('key');
print_r($data);
}
要么
public function viewSession_v2(){
$data = session()->get('key');
print_r($data);
}
