Laravel 6搜索路线给予404

Question

我已经尝试了一些东西，但是在我的 Homestead 安装中有一些原因 Laravel 6.17 我有一条 /search 路由给出了 404。如果用户不这样做，我希望它能重定向不要在搜索字段中输入任何内容。

我执行了运行 route:list 命令并得到了这个

vagrant@homestead:~/www/nettubenew$ php artisan route:list

Answer 1

更改这些行的顺序：

Route::get('/{channel}','ChannelController@index');
Route::get('/search','SearchController@index')->name('search');

你有一个路由，它接受一个变量（名为 channel），当你调用 search 路由时，它将 search 字符串作为 channel 变量传递。

Answer 2

在 "search" 路由之前您有另一个带有“/{channel}”的路由，它将匹配您键入的所有内容，还有 "search"，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：

如果不使用，请删除此行（404 可能是从 ChannelController 中不存在的方法或未找到的 "channel" 调用的）。
如果使用此路由 - 您输入它的方式是不好的做法（并且会导致错误）。最好用'channel/{channel}'.
如果您真的需要捕获在 URL 的级别 0 上键入的每个文本，只需将此路由放在搜索路由之后，最后。
