Php AmazonS3-上传后调用文件

我正在使用php脚本将文件上载到AmazonS3

$s3->putObjectFile($url,$bucket,$filename, S3::ACL_PRIVATE,array(),array("Content-Type" => "application/json"));

上传后，我需要立即从文件中获取一些信息，并通过Cloudfront调用它，但我发现该文件仅在几分钟后可用

你知道为什么吗？有没有办法解决这个问题？ 有没有办法让文件立即可用

谢谢你

我马上就可以通过这次考试了

也许你的上传是异步进行的，而上传还没有完成？

我马上就可以通过这个测试了
