php 文件上传至OSS及删除远程阿里云OSS文件
今天给大家介绍php 文件上传至OSS及删除远程阿里云OSS文件的方法,在删除文件的时候大家记住千万不要带域名,具体操作示例参考下本文。
删除的时候记住不要带域名,也不要带'/'这个路径符号,如全路径是:'https://hxty.oss-cn-beijing.aliyuncs.com/data/pdf/contract/2021-06-16/HXSHB21061611594482340c.pdf',则这里的path_file路径为:'data/pdf/contract/2021-06-16/HXSHB21061611594482340c.pdf'。
