Question

以下代码从我的控制器运行，并在一台服务器上导致502错误坏网关。我无法在我的服务器上重现。 502 Bad Gateway的原因是什么？

function index()
{
    $this->_reload();
}

function _reload($data=array())
{
    $person_info = $this->Employee->get_logged_in_employee_info();
    $data['cart']=$this->sale_lib->get_cart();
    $data['modes']=array('sale'=>$this->lang->line('sales_sale'),'return'=>$this->lang->line('sales_return'));
    $data['mode']=$this->sale_lib->get_mode();
    $data['items_in_cart'] = $this->sale_lib->get_items_in_cart();
    $data['subtotal']=$this->sale_lib->get_subtotal();
    $data['taxes']=$this->sale_lib->get_taxes();
    $data['total']=$this->sale_lib->get_total();
    $data['items_module_allowed'] = $this->Employee->has_permission('items', $person_info->person_id);
    $data['comment'] = $this->sale_lib->get_comment();
    $data['email_receipt'] = $this->sale_lib->get_email_receipt();
    $data['payments_total']=$this->sale_lib->get_payments_total();
    $data['amount_due']=$this->sale_lib->get_amount_due();
    $data['payments']=$this->sale_lib->get_payments();
    $data['payment_options']=array(
        $this->lang->line('sales_cash') => $this->lang->line('sales_cash'),
        $this->lang->line('sales_check') => $this->lang->line('sales_check'),
        $this->lang->line('sales_giftcard') => $this->lang->line('sales_giftcard'),
        $this->lang->line('sales_debit') => $this->lang->line('sales_debit'),
        $this->lang->line('sales_credit') => $this->lang->line('sales_credit')
    );

    $customer_id=$this->sale_lib->get_customer();
    if($customer_id!=-1)
    {
        $info=$this->Customer->get_info($customer_id);
        $data['customer']=$info->first_name.' '.$info->last_name;
        $data['customer_email']=$info->email;
    }
    $data['payments_cover_total'] = $this->_payments_cover_total();
    $this->load->view("sales/register",$data);
}

Answer 1

似乎setcookie被称为太多导致了502错误。我不确定NGNIX是否是限制，但这解决了这个问题。

Answer 2

这是一个NGINX / CI问题，如果您无法更改设置，那么将会话更改为为我工作的数据库

$config['sess_use_database'] = TRUE;

Answer 3

它可能是一个有缺陷的加密库。尝试设置：

$config[‘sess_encrypt_cookie’] = FALSE;
