Laravel5.4中的TokenMisMatchException

我是Laravel和PHP的新手.我正在使用POST方法来获取用户请求,并且我在verifyCSRFToken.php第68行中获取了TokenMismatchException.检查了server.php中的日志,发现以下内容.

[2017-06-13 11:29:55] local.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Undefined constant 'home' in C:\Users\Dikesh Kumar\blog\vendor\laravel\framework\src\Illuminate\Container\Container.php:762

有人可以帮忙吗？

Laravel可以轻松保护您的应用程序免受跨站点请求伪造(CSRF)攻击.跨站点请求伪造是一种恶意攻击,由此代表经过身份验证的用户执行未经授权的命令.

Laravel为应用程序管理的每个活动用户会话自动生成CSRF"令牌".此令牌用于验证经过身份验证的用户是否是实际向应用程序发出请求的用户.

无论何时在应用程序中定义HTML表单,都应在表单中包含隐藏的CSRF令牌字段,以便CSRF保护中间件可以验证请求.您可以使用csrf_field帮助程序生成令牌字段:

    {{ csrf_field() }}
    ...
