laravel 路由需要缺失

Question

缺少 [路由：conversations.show] [URI：conversations{user}] [缺少参数：user] 的必需参数。

我不知道如何解决这个问题，因为只有当我发送消息时，当我回来时我没有问题并且消息就在那里。

I try to have a page where you have yours conversations but when i sent message an error happen

Answer 1

您已经这样定义了您的路线。

Route::get('conversations/{user}', [App\Http\Controllers\ConversationsController::class, 'show'])->name('conversations.show');

然后，当您使用助手访问路线网址时route()。您应该将 url 参数键入提示为user。如图所示，有很多地方你做错了。

route('conversations.show', ['user' => $user->id])

或者，您可以避免使用关联数组，将其设置为方法调用的参数。

route('conversations.show', $user->id)
