推荐答案
我认为与你用于调用的 http 方法有关.可能你使用了 get 方法，但你需要一个 post 方法
I think is related to the http method you use for call. Probably you use a get method but you need a post method
你应该有这样的东西
array('label'=>'Delete', 'url'=>'#',
'linkOptions'=>array('submit'=>array('event/delete','id'=>$model->id),
'confirm'=>('Are you sure to delete this item?'),
'method' =>'post')),
检查你是否有方法=发布
check if you have method = post
deleteAction 只允许通过 POST 请求删除
deleteAction only allow deletion via POST request
