laravel 5.5 The page has expired due to inactivity. Please refresh and try again

在laravel框架中有此要求：任何指向 web 中 POST, PUT 或 DELETE 路由的 HTML 表单请求都应该包含一个 CSRF 令牌，否则，这个请求将会被拒绝

1、taiji/app/Http/Middleware/VerifyCsrfToken.php

中把路由加进去免验证

 protected $except = [
        'upload',
        'upload/qrcode',
        'upload/video'
    ];

2、
或在表单中加入{{ csrf_field() }}

<form method="POST" action="/profile"> 
{{ csrf_field() }} 
... </form>
