我试图传递多个参数到同一个视图，laravel抛给我一个错误，说未定义变量$博客。我已经将变量$all_cards传递给同一个视图，但从HomeController.php的另一个控制器传递给index（）。问题是Laravel正在读取$all_cards，但没有第二个var$blog。Laravel总是抛出相同的错误。

博客控制器。php

class BlogController extends Controller
{
    public function index()
    {
        $blogs = Blog::all();
        return view('home.home',['blogs'=>$blogs]);
    }
}

网状物php

use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', [App\Http\Controllers\BlogController::class, 'index'])->name('home');

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');

Route::get('/home/add-deposit', [App\Http\Controllers\HomeController::class, 'addDeposit'])->name('home.addDeposit');
Route::post('/home/add-deposit', [App\Http\Controllers\HomeController::class, 'updateDeposit'])->name('home.addDeposit');

Route::put('/home/update-card/{id}', [App\Http\Controllers\HomeController::class, 'updateCard'])->name('home.updateCard'); //dovrsi

Route::get('/home/buy-food/{id}' , [App\Http\Controllers\HomeController::class, 'buyFood'])->name('home.buyFood');

Route::get('/home/show-chef-form', [App\Http\Controllers\HomeController::class, 'chefForm'])->name('home.chefForm');
Route::post('/home/show-chef-form', [App\Http\Controllers\HomeController::class, 'saveChef'])->name('home.saveChef');
