Question

我在自定义路由器上工作（主要是为了好玩）。这是一项正在进行中的工作，所以欢迎任何建议！

但我的主要问题是de css / js文件不再加载了。看起来文件的路径附加到当前URL，因此用户/（css路径）。

在Chrome和Firefox中，资源只会继续加载，不会返回任何响应/代码。如果我故意引发异常，例如改变文件路径，我确实看到了返回异常的html。

我已经做了很多调试，似乎无法弄明白。

Answer 1

通过获取正确的标题（text/css或application/javascript来解决那些问题）来解决它，回显文件内容然后返回;

我将代码放在handle {（）方法中的if ($this->isAssetRoute($route))语句中。该语句中的所有其他代码都将被删除。
