使用Laravel路线，顺序很重要。具有动态段（如 files / {file} 或资源路由）的路由应始终在之后定义为静态的路径。否则，Laravel将将您的URL中的共享部分解释为ID。

With Laravel routes, the order matters. Routes with dynamic segments like files/{file} or resource routes should always be defined after the ones that are static. Otherwise Laravel will interpret the share part in your URL as ID.

所以，你已经想出了自己您只需要更改路线的顺序：

So, as you've figured out yourself you simply need to change the order of your routes:

Route::put('/files/share', 'FileController@test');
Route::resource('/files', 'FileController');
