Laravel Ajax内部Servo 500(内部服务器错误) [英] Laravel ajax internal servor 500 (internal server-error)

问题描述

我有一个存储在会话中的购物车，我想刷新会话而不重新加载页面 我已经试过了: 查看:

I have a shopping cart which is stored in session and I want to refresh the session without reloading the page I have tried this: View:

<a href="#" id="product" data-id="{{ $product->id }}" class="item_add single-item hvr-outline-out button2">Add to cart</a>

<script>
$(document).ready(function() {
    $('#product').click(function(event) {
        event.preventDefault();

        let url = "{{ route('add-to-cart') }}";
        let id = $(this).data('id');

        $.ajax({
            url: url,
            type: 'POST',
            data: {product_id: id, _token: "{{ Session::token() }}"}
        })
        .done(function() {
            console.log("success");
        })
        .fail(function() {
            console.log("error");
        })
    });
});

路线:

Route::post('/add-to-cart', 'ProductsController@addToCart')->name('add-to-cart');

ProductsController:

ProductsController:

public function addToCart(Request $request)
{
    if ($request::ajax()) {
        $id = $request->product_id;

        $product = Product::find($id);

        if (Session::has('products')) {
            $products = Session::get('products');
            $products[] = $product;
            Session::put('products', $products);
        }

        else {
            $products = array($product);
            Session::put('products', $products);
        }

        return response()->json();
    }
}

当我单击添加到购物车"时，它在控制台中显示500(内部服务器错误)

And when I click add to cart it gives 500 (Internal Server Error) in the console

推荐答案

当您应该改为使用->时，您正在静态访问ajax()方法(使用::):

You're accessing the ajax() method statically (using ::), when you should be using -> instead:

if ($request->ajax()) {

使用Laravel日志文件

如评论中所述，Laravel可能在storage/logs/laravel.log中告诉了您这一点，并附带了很长的调用堆栈跟踪(您提到的行，以#38"和#39"开头).只需向上滚动到#1"之前，您就会找到罪魁祸首.

As mentioned in the comments, Laravel is probably telling you this in storage/logs/laravel.log, complete with a long call-stack trace (the lines that you mentioned, beginning with "#38" and "#39"). Just scroll up to before "#1" and you'll find your culprit.
