Question

我是Laravel的新手，我试过这个：

路由器

Route::get('productdetails/{id}', function($id){
'ProductDetailsController@productdetails' .$id;

}）;

ProductDetailsController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class ProductDetailsController extends Controller
{
    public function inventory(){
    $inventory = DB::select('select * FROM inventory WHERE barcode = ?', [$id]);;
    return view('productdetails',['inventory'=>$inventory]);
    }
}

我得到了：

RouteCollection.php第161行中的NotFoundHttpException：

路由的正确语法是：

void IPushNotificationListener.OnMessage(JObject parameters, DeviceType deviceType)
    {
        try
        {

            Intent intent = new Intent(Android.App.Application.Context, typeof(MainActivity));
            Intent[] intar = { intent };
            PendingIntent pintent = PendingIntent.GetActivities(Android.App.Application.Context, 0, intar, 0);
            intent.SetAction("notification");
            //Json Response Recieved 
            Dictionary<string, string> results = JsonConvert.DeserializeObject<Dictionary<string, string>>(parameters.ToString());
            Notification.Builder builder = new Notification.Builder(Android.App.Application.Context)
     .SetContentTitle(results["contentTitle"])
     .SetContentText(results["message"])
     .SetContentIntent(pintent)
     .SetSmallIcon(Resource.Drawable.icon);
            // Build the notification:
            Notification notification = builder.Build();

            //Clear notification on click
            notification.Flags = NotificationFlags.AutoCancel;

            // Get the notification manager:
            NotificationManager notificationManager =
                Android.App.Application.Context.GetSystemService(PushNotificationService.NotificationService) as NotificationManager;
           //notificationId  need to be unique for each message same ID will update existing message
            int notificationId = Convert.ToInt32(results["Id"]);
            // Publish the notification:
            notificationManager.Notify(notificationId, notification);
        }
        catch (Exception)
        {
        }
    }

方法应如下所示：

Route::get('productdetails/{id}', 'ProductDetailsController@inventory');
