我收到以下错误：TokenMismatchException in compiled.php line 2930:
该代码在运行在一个 Red Hat 服务器 上，使用的是 php 5.6 ，我也在运行 php 5.5.9 的 Ubuntu 服务器 上进行了测试，结果完全正常。本地运行也完全正常。
原始的 GET 请求似乎会在 storage/framework/sessions 中创建两个会话文件，这意味着当通过 POST 发送表单时，会话就不同了。
我已经检查了：
- 重定向
- 服务器上的日期/时区问题
session.php和app.php中的设置问题
最奇怪的是为什么在 GET 请求时会生成两个会话文件。
一旦点击登录按钮，就会触发 csrf 中间件，显示令牌不匹配。
我正在使用表单的 HTML 生成器，这意味着 _token 已经被设置，因此不需要手动操作。

HTML/Form生成器，这会在使用Form::open时自动生成_token。我也发布了答案。 - Matt Stephens
