删除多版本对象(Node.js SDK)
开发过程中,您有任何问题可以在github上提交issue,或者在华为云对象存储服务论坛中发帖求助。
功能介绍
可以通过ObsClient.deleteObject接口指定VersionId参数删除多版本对象,接口定义请参见删除对象(Node.js SDK)。
可以通过ObsClient.deleteObjects接口传入每个待删除对象的VersionId参数批量删除多版本对象,接口定义请参见批量删除对象(Node.js SDK)。
代码示例一:删除单个多版本对象
本示例用于删除examplebucket桶中的example/objectname对象,对应的版本号是 G001117FCE89978B0000401205D5DC9A。

代码示例二:批量删除多版本对象
本示例用于批量删除examplebucket桶中的objectname1、objectname2、objectname3对象。
