laravel5.2 如何删除session。

Jun 06, 2016 pm 08:09 PM
laravel php

做用户退出登录,ajax调用删除session登录时设置的$request->session()->put('user','value');
使用了$request->session()->forget('user');然后跳转到login页
但是发现跳转后获取的session数据仍然是删除前的session状态,所以还是保持了登录状态。求教是我用法错误吗?

下面是ajax调用的方法:

<code>    public function logout(Request $request)
    {
        if ($request->session()->has('user')) {
            $is_forgotten = $request->session()->forget('user');
            if ($is_forgotten === null)
                echo json_encode(['result' => 1]);
            exit;
        }
        echo json_encode(['result'=>0,'msg'=>'退出失败']);
        exit;
    }</code>
Copy after login
Copy after login

下面是登录时给session的user赋值的代码

<code>    public function valid(Request $request)
    {
        $r = $request->all();
        $validator = Validator::make($r,[
            'username'=>'bail|required',
            'password'=>'bail|required|integer',
        ]);

        if ($validator->fails()) {
            return redirect('admin/login')->withErrors($validator)->withInput();
        }

        $where = [
            'name'=>$r['username'],
            'pwd'=>md5($r['password']),
        ];

        $hasExists = AdminModel::hasExists($where);

        if (null !== $hasExists) {
            $request->session()->put('user',json_encode(['name'=>$r['username']]));
            return redirect('admin');
        } else {
            return redirect('admin/login')->with('hasExists','用户名或密码错误');
        }
    }</code>

建议楼主在了解一下Larave的Session机制,如果你的代码中途有exit,最好在它之前Session::save()一下
