laravel5.2 session的问题

Jun 06, 2016 pm 08:14 PM
laravel php

第一个问题

<code>Route::get('test', function () {
        session(['wechat.oauth_user'=>1]);
        dd(session('wechat.oauth_user'));

    });</code>
Copy after login
Copy after login

输出1,然后我把session(['wechat.oauth_user'=>1]);注释了

<code>Route::get('test', function () {
        //session(['wechat.oauth_user'=>1]);
        dd(session('wechat.oauth_user'));

    });</code>
Copy after login
Copy after login

刷新页面,输出null,这是为什么?

第二个问题

我使用了overtrue/wechat的插件,用插件自带的中间件成功获取了用户信息,然后user路由里也输出了session

<code>    public function handle($request, Closure $next, $guard = null)
        {
            $wechat = app('EasyWeChat\\Foundation\\Application');
    
            if (!session('wechat.oauth_user')) {
                if ($request->has('state') && $request->has('code')) {
                    session(['wechat.oauth_user' => $wechat->oauth->user()]);
                    
                    return redirect()->to(url($request->url(), array_except($request->query(), ['code', 'state'])));
                }
    
                return $wechat->oauth->redirect($request->fullUrl());
            }
    
            return $next($request);
        }</code>
Copy after login
Copy after login
<code>    Route::get('user', function () {
    
            dd(session('wechat.oauth_user'));
        });</code>
Copy after login
Copy after login

在这个基础上,我建立了自己的中间件UserMiddleware

<code>    public function handle($request, Closure $next)
        {
            if(Auth::guard('web')->guest()){
                if (!session('wechat.oauth_user')) {
                    return redirect('user');
                }
                else{
                    User::CreateOrLogin(session('wechat.oauth_user'));
                }
            }
    
    
            return $next($request);
        }</code>
Copy after login
Copy after login

User.php 方法 CreateOrLogin

<code>    public static function CreateOrLogin($data){
            $user=self::getByOpenid($data['id']);
            if(!$user){
                $create=['openid'=>$data['id']];
                $user=self::create($create);
            }
            Auth::guard('web')->login($user);
        }
    
        public static function getByOpenid($openid){
            return self::where('openid','=',$openid)->first();
        }</code>
Copy after login
Copy after login

一切都是ok的,但是每次刷新页面都会执行微信获取用户信息的接口,然后一个个注释掉,发现Auth::guard('web')->login($user);这句注释掉后,刷新页面就不会再跳转到微信,加上去就要跳转到微信获取用户信息接口,感觉像是login会清除掉session一样

问题三

<code>Route::group(['middleware' => ['web']], function () {

    Route::get('test', function () {
        dd(auth()->user());

    });


    Route::get('test2', function () {
        dd(auth()->loginUsingId(1));

    });

});</code>
Copy after login
Copy after login

先访问test2,成功登陆,再访问test,输出null,为什么。。。

问题一和问题二和问题三没有关联,求大神解答
