5.关于laravel框架中Contorller

public function request(Request $request){
//1.取url中的值
echo $request->input('name');
//输出所有值
$str = $request->all();
//dd($str);
//2.判断是否存在值
if($request->has('name')){
echo $request->input('name');
}else{
echo '无参数';
}

//3.判断请求类型
echo $request->method();
//判断是否为想要的请求类型
if($request->isMethod('POST')){
echo 'yes';
}else{
echo 'no';
}
//判断是否为ajax请求
$res = $request->ajax();
//dd($res);
//判断当前路由是否满足自己设定的规则
$resture = $request->is('test/*');
dd($resture);
//输出当前的url,输出结果不带参数
echo $request->url();

}

2.Controller中Session

首先需要sessionstatrt，laravel中，sessionstart在中间件web中，所有路由形式可以写成

Route::group(['middleware'=>['web']],function (){Route::any('/session1',['uses'=>'StudentController@session1']);Route::any('/session2',['uses'=>'StudentController@session2']);});

初次体验中，Session::put和Session::get均无法使用，不确定是否是版本问题

session用法

public function request(Request $request){//1.取url中的值echo $request->input('name');//输出所有值$str = $request->all();//dd($str);//2.判断是否存在值if($request->has('name')){echo $request->input('name');}else{echo '无参数';}//3.判断请求类型echo $request->method();//判断是否为想要的请求类型if($request->isMethod('POST')){echo 'yes';}else{echo 'no';}//判断是否为ajax请求$res = $request->ajax();//dd($res);//判断当前路由是否满足自己设定的规则$resture = $request->is('test/*');dd($resture);//输出当前的url,输出结果不带参数echo $request->url();}public function session1(Request $request){//1.Http request session()// $request->session()->put('key1','value1');//2.session()//  session()->put('key2','value2');//3.Session//Session::forget('key1');$request->session()->put('key3','test');//Session::put('key3','value3'); laravel-v5.2.15无效// dd( Session::all() ); //取出来看看是否put成功 可用if(Session::has('key3')){echo 'session zc';}else{echo '失败';}}public function session2(Request $request){//1.Http request session()//echo $request->session()->get('key1');//2.session()//echo session()->get('key2');//3.Session// echo Session::get('key3');  laravel-v5.2.15无效//  echo $request->session()->get('key2','default');//获取session中的key2，不存在则输出一个默认值//Session::get('key2','default');//     echo $request->session()->pull('key3','no');//获取session中的key3值，并删除该session//Session::pull('key2',default);//以数组的形式存储session//            1/*            $request->session()->put(['key1'=>'key1','key2'=>'key2','key3'=>'key3',]);dd (session()->all());*///            2//Session::push('xx','xx');$request->session()->push('test1','test1');$request->session()->push('test1','test2');$request->session()->push('test1','test3');dd(session()->all());}

一个关于laravel中session的小总结：

1.永久存储：put('xx','yy');

2.获取数据：get('xx');

3.获取所有：get()->all();

4.获取后删除：pull('xx');

5.判断存在：has('xx');

6.快闪数据：flash('xx','yy');//获取一次后就删除

7.删除指定数据：forget('xx');

8.删除所有数据：flush();

9.数组形式：1.push();  2.put(['xx'=>'yy']);

public function request(Request $request){
//1.取url中的值
echo $request->input('name');
//输出所有值
$str = $request->all();
//dd($str);
//2.判断是否存在值
if($request->has('name')){
echo $request->input('name');
}else{
echo '无参数';
}

//3.判断请求类型
echo $request->method();
//判断是否为想要的请求类型
if($request->isMethod('POST')){
echo 'yes';
}else{
echo 'no';
}
//判断是否为ajax请求
$res = $request->ajax();
//dd($res);
//判断当前路由是否满足自己设定的规则
$resture = $request->is('test/*');
dd($resture);
//输出当前的url,输出结果不带参数
echo $request->url();

3.Conroller-Response

 public function response(){//echo 'response';//响应json数据/*        $str =['error' =>0,'errMsg'=>'success','name'  =>'Error',];return response()->json($str);*///重定向// return redirect('session2');return redirect('session2')->with('msg','test');//跳转，并带入数据，数据属于快闪数据，只显示一次return redirect()->back();//返回上一级页面}
