我已经尝试了一些东西，但出于某种原因，在我安装Laravel 6.17的Homestead上，我有一个单一的/search路径，它给出了404。如果用户没有在搜索字段中输入任何内容，我希望它能重定向。
我确实运行了route:list命令，得到了这个
vagrant@homestead:~/www/nettubenew$ php artisan route:list

在"搜索"路线之前，您有另一个带有"/｛channel｝"的路线，它将与您键入的所有内容相匹配，也是"搜索"，因此永远不会调用SearchController：
Route::get('/{channel}','ChannelController@index');
Route::get('/search','SearchController@index')->name('search');
您有3个选项：
如果未使用此行，请删除此行(404可能是从ChannelController中不存在的方法或未找到的"通道"调用的(。
如果使用这个路由-你键入的方式是不好的做法(这导致了错误(。最好使用"channel/｛channel｝"。
如果你真的需要捕捉在URL的0级上键入的每一条文本，只需在搜索路线的最后放上这条路线。
更改这些行的顺序：
Route::get('/{channel}','ChannelController@index');
Route::get('/search','SearchController@index')->name('search');
您有一个采用变量(名为channel(的路由，当您调用search路由时，它会将search字符串作为channel变量传递。
