Wordpress WoCommerce wc api返回错误的类

我有两个Woocommerce支付网关类，分别是WC_banklink_seb和WC_banklink_swedbank，最后一个在更新Woocommerce 2.2至2.4时停止工作

集成和支付仍然有效，但使用wc api的返回URL不起作用

当我使用WC_banklink_swedbank支付网关并从支付提供商返回URL时，我得到以下错误：

致命错误：第304行的…/wp content/plugins/banklink_seb/banklink.php中的签名无效

WC_banklink_swedbank类实际上位于文件夹…/wp content/plugins/banklink_swedbank中/

我的问题是为什么wc api从另一个支付网关返回一个类？WC_banklink_seb和WC_banklink_swedbank类之间唯一的共同点是它们都扩展了WC_支付网关

这两个代码都来自类和插件名称，它们几乎完全相同，因为设置是在adin面板上设置的

最让我困惑的是，当我禁用WC_banklink_seb类的插件时，WC_banklink_瑞典银行又开始工作了

操作名称中存在的问题不是唯一的有效\u请求。两种支付方法都注册了相同的操作，因此只有第一种方法真正注册

add_action('valid_request', array($this, 'successful_request'));

操作的名称应替换为唯一名称，例如：

add_action('valid_request_swedbank', array($this, 'successful_request'));

当然，在相应的do_操作中更改操作名称

do_action( "valid_request_swedbank", $_REQUEST );
