Paymill - 交易失败 - '' 长度小于 1 个字符

Question

我被这个错误困扰了很长一段时间，我不知道如何解决这个问题。我将传递给事务对象的检查数据加倍甚至三倍，但仍然无法找出为什么它一直向我抛出这个“'' is less than 1 characters long”错误消息。我什至在 Internet 上找不到该错误消息的文档。

我的代码当前状态的简要概述：

1. 我的交易对象创建包含在 try..catch 语句中(\Paymill\Services\PaymillException)

2. 正确创建了客户端和付款对象。我可以在我的 paymill 控制面板上看到这两个。

3. 我也将购物车数组传递给 Transaction 对象

4. 正在使用以下序列导出项目描述：trim(substr(html_entity_decode($item['description']), 0, 123)) . "..."

5. 正在通过信用卡付款

6. 第一次支付成功第二次失败

这里是部分异常对象输出：

                                                        (

                                            [_serviceResource:protected] => Transactions/
                                            [_filter:protected] => 
                                        )

                                    [1] => create
                                )

                        )

这就是我发起交易的方式

$transaction->setClient($this->getClient()->getId())
                        ->setPayment($this->getPayment()->getId())
                        ->setToken($this->getToken())
                        ->setAmount($this->getBasket('total')*100)
                        ->setBillingAddress($billing_address)
                        ->setShippingAddress($shipping_address)
                        ->setCurrency($this->getConfig('currency'))
                        ->setItems($items)
                        ->setDescription("Order ID: " . $this->getBasket('cart_order_id'))
                        ->setShippingAmount($this->getBasket('shipping')['value']*100);
            $this->d($this->getClient());
            $r = $this->getRequest()->create($transaction);

Answer 1

问题解决了。其中一个项目的描述字段为空。奇怪的是 Exception 没有包含导致问题的字段名称。
