在这里，我试图使用laravel创建一个注册页面。然而，我对代码中包含"；会话"；。当我去掉那个部分时，代码是有效的，但当我把它留在里面时，它就不起作用了。我从中获得代码的教程说，代码的会话部分对安全性非常重要。这是代码：
section ('content')
<div class = "row">
<div class = "col-md-6">
<h3> Sign Up </h3>
<form action ="{{route ('signup')}}" method = "post">
<div class = "form-group">
<label for= "email"> your E-mail </label>
<input class = "form-control" type="text" name = "email" id= "email">
</div>
<div class = "form-group">
<label for= "first_name"> your first name </label>
<input class = "form-control" type="text" name = "first_name" id= "first_name">
</div>
<div class = "form-group">
<label for= "password"> your password </label>
<input class = "form-control" type="password" name = "password" id= "password">
</div>
<button type = "submit" class = "btn btn-primary">submit</button>
<input type = "hidden" name = "_token" value="{{session::token() }}">
</form>
使用Session而不是session。注意，S是大写字母。如果不起作用，则转到：Session::token()
