Ajax 调用 Laravel 路由

Question

如何在 Ajax 中正确调用 Laravel 路由或控制器？

出现错误并说：

路线 [product/create] 未定义。(查看: C:\xampp\htdocs\laravel\resources\views\jsBlade\logoInput.blade.php) (查看: C:\xampp\htdocs\laravel\resources\views\jsBlade\logoInput.blade.php)

我的路线如下所示：

# Middleware group if user is successfully logged in
Route::group(['middleware' => 'auth'], function ()
{
    Route::get('/home', ['as' => 'home', 'uses' => 'PageController@showHome']);

    # Product group
    Route::group(['prefix' => 'product'], function ()
    {
        Route::get('/', ['as' => 'indexProduct', 'uses' => 'ProductController@indexProduct']);
        Route::get('new', ['as' => 'newProduct', 'uses' => 'ProductController@newProduct']);
        Route::get('show/{productID}', ['as' => 'showProduct', 'uses' => 'ProductController@showProduct']);
        Route::get('edit/{productID}', ['as' => 'editProduct', 'uses' => 'ProductController@editProduct']);
        Route::post('create', ['as' => 'createProduct', 'uses' => 'ProductController@createProduct']);
        Route::post('update', ['as' => 'updateProduct', 'uses' => 'ProductController@updateProduct']);
        Route::delete('destroy', ['as' => 'destroyProduct', 'uses' => 'ProductController@destroyProduct']);
    });

});

我的阿贾克斯：

$("#input-logo").fileinput({
    uploadUrl: '{{route("product/create")}}',
    type: 'POST',
    allowedFileExtensions: ["jpg", "png", "gif", "jpeg"],
    allowedFileTypes: ['image'],
    headers: {
       'X-CSRF-Token': $('#_token').val(),
    }
}).on('filepreupload', function() {
    $('#kv-success-box').html('');
}).on('fileuploaded', function(event, data) {
    $('#kv-success-box').append(data.response.link);
    $('#kv-success-modal').modal('show');
});

</script>

控制器

<?php

namespace App\Http\Controllers;

use Input;
use App\Product;
use App\Companies;
use App\Http\Controllers\Controller;


class ProductController extends Controller
{
    public function createProduct()
    {
        $data = Input::all();

        $product = new Product;

        $product->fill($data);
        if($product->save())
        {
            return redirect()->route('root')->with('message','Success');;
        }
    }
}

Firefox 给出了这个错误信息：

SyntaxError: JSON.parse: JSON 数据的第 1 行第 1 列出现意外字符。

改变这部分

uploadUrl: '{{route("product/create")}}',

对此

uploadUrl: '{{url("product/create")}}',

并将 csrf 令牌添加到 ajax 中的标头

headers: {
    'X-CSRF-Token': '{{ csrf_token() }}',
},
