问题1：我的个人账号，上传zip包到OBS,zip包内文件数量超过480个左右就不解压了，官方文档说明的限制数量是65536个。问题2：在线解压策略在修改过后，策略列表里面只有一个策略，但实际解压过程中，修改前后的策略都存在。

对于OBS文件ACl类型为私有读写的图片文件，图片文件url需要授权才能获取。如何给文字识别OCR服务授权获取图片？

OBS nodejs 没办法获取 进度 速度吗？

OBS断点续传，暂停后多长时间内可以继续上传？有没有时间限制？

OBS初始化及上传代码均为文档复制后替换了必要参数，但是调用这个放大就会报错。

调用OBS C SDK 的append_object接口追加写OBS文件，OBS概率性报错，报错信息为：with OBS error code:ErrorUnknown message: Where you proposed append to is not equal to length.推测是前面的报文没有及时下盘，导致当前报文写入错误。请问这种推测是否正确，如果正确应该如何规避；如果不正确请告知报错原因。

为什么PHP OBS 删除文件夹中的对象，连文件夹都被删除了？例如建了一个文件夹 /img要删除img中的图片 /img/1.jpg; 执行删除之后，img文件夹也被删除了。怎么做到只删除文件夹的文件，不删除文件夹？
