asp.net – AWS对象失效 – /如何确保从Edge中删除图像

它说我们可以使用外卡

让我们说我们有路径

https://cdn_url/rootimage/second/1/type/2.png

所以,如果我写

AmazonCloudFrontClient objClient = new AmazonCloudFrontClient(ConfigurationManager.AppSettings["s3accesskey"],ConfigurationManager.AppSettings["s3secret"]);
        objClient.CreateInvalidation(new CreateInvalidationRequest
        {
            DistributionId = ConfigurationManager.AppSettings["CDNDistributionId"],InvalidationBatch = new InvalidationBatch 
            { 
                Paths = new Paths { Items = "/cdn_url/rootimage/*",Quantity = 1 } 
            }
        });

以上代码是否有效.
那么数量将是1还是所有实际图像的数量.

如何验证失效是否完整.

我也尝试在门户网站上手动操作,几分钟后我看到它说失效已经完成,我怎么能确定如果图像从Edge中移除.

谢谢
