What should I do if the yii2 submission form prompts that it cannot be verified?

public function init()
{
    $this->enableCsrfValidation = false;
}
//或者
public function __construct($id, $module, $config = [])
{
    $this->menuActive = 2;
    $this->enableCsrfValidation = false;
    parent::__construct($id, $module, $config);     
          
}
//总之把enableCsrfValidation设为false就可以了

var csrfToken = $('meta[name="csrf-token"]').attr("content");
$.ajax({
    type: 'POST',
    url: url,
    data: {
        _csrf:csrfToken},
        success: success,
        dataType: dataType
});
