将json发布到laravel 5.1问题

Question

我正在向laravel提交此帖子请求（来自ios使用AFNetworking，不介意语法）

{
    cart =     {
        "company_id" = 1;
        quantity = 3;
        "service_product_id" = 1;
    };
    options =     (
                {
            "company_id" = 1;
            "service_product_option_id" = 1;
            "service_product_option_value_id" = 2;
        },
                {
            "company_id" = 1;
            "service_product_option_id" = 2;
            "service_product_option_value_id" = 3;
        }
    );
}

这是laravel获取的请求，我只是让它返回调试目的的请求

public function postCart(Request $request)
{
    return $request->all();
}

和结果

{
    cart =     {
        "company_id" = 1;
        quantity = 3;
        "service_product_id" = 1;
    };
    options =     (
                {
            "company_id" = 1;
        },
                {
            "service_product_option_id" = 1;
        },
                {
            "service_product_option_value_id" = 2;
        },
                {
            "company_id" = 1;
        },
                {
            "service_product_option_id" = 2;
        },
                {
            "service_product_option_value_id" = 3;
        }
    );
}

即使传递的选项数组包含两个内部对象，它也会在laravel端被处理为6个不同的对象。为什么这样以及如何解决这个问题？
