对.... 疯狂的是，整个代码看起来都是正确的，但仍然出现此错误。 但一定是某个地方出了问题。
产品控制器
public function new(Request $request){
$request->validate([
'name' => 'required|max:255|min:10|string',
'price' => 'numeric|max:255|required',
'stock' => 'required|numeric|max:255',
'description' => 'required|string|max:5000|min:10',
'picture' => 'required|image',
'picsupp1' => 'image',
'picsupp2' => 'image',
'picsupp3' => 'image',
'delivery' => 'required|string',
'category' => 'required|string',
]);
$crypt = openssl_random_pseudo_bytes(30);
$token = bin2hex($crypt);
$product = new Product;
$product->name = $request->input('name');
$product->price = $request->input('price');
$product->stock = $request->input('stock');
$product->description = $request->input('description');
$product->picture = request('picture')->store('articles','public');
$product->locked = 0;
if(request('picsupp1')){
$product->picsupp1 = request('picsupp1')->store('articles','public');
}else{
$product->picsupp1 = '';
}
if(request('picsupp2')){
$product->picsupp2 = request('picsupp2')->store('articles','public');
}else{
$product->picsupp2 = '';
}
if(request('picsupp3')){
$product->picsupp3 = request('picsupp3')->store('articles','public');
}else{
$product->picsupp3 = '';
}
$product->delivery_token = $request->input('delivery');
$product->category_token = $request->input('category');
$product->vendor_id = Auth::user()->id;
$product->token = $token;
$product->save();
return redirect(route('index'))->with('success','Product added with success !');
}

最后定义的路线：
Route::post('/vendor/product/action/new', [App\Http\Controllers\Market\ProductController::class, 'new'])->name('product.action.new');
是否有人可能在某个地方看到错误或错误，从昨天开始就一直忙于这个问题，以前从未遇到过这个问题。
问题在于您在表单中使用的 HTTP 方法以及在路由中定义的方法。在您的表单中，您使用的是
@method('PUT')PUTPOST要解决此问题，您应该从表单中删除
@method('PUT')POST<form method="POST" action="{{ route('product.action.new') }}" enctype="multipart/form-data" >
@csrf
<!-- rest of your form fields -->
</form>
