Question

我正在此控制器上发送帖子数据，以便进行测试我在执行方法中添加了die，如下面的代码所示。

但即使我没有在构造函数

中使用任何参数，我也会遇到奇怪的错误

错误

base = df.loc[df.index[0], 'A'].minute
df.groupby(['B', 'C', pd.Grouper(freq='60T', key='A', base=base)]).describe()

我的代码

Answer 1

__construct()方法必须是Magento\Framework\App\Action\Context的实例，但没有给出。它应该像

  /**
 * @param Context $context
 */
public function __construct(
    Context $context
) {
    parent::__construct($context);
}

注意：部署模块后，删除var / di和var / generation文件夹并重新编译。
