You can delete one or more objects at a time, delete objects whose names contain a specified prefix, or delete a specified directory and all objects in the directory.
Warning
- Objects cannot be restored after they are deleted. Exercise caution when you perform this operation.
To maintain OSS-HDFS stability and prevent data loss, do not delete objects from the
.dlsdata/directory.
Delete a single object
The following sample code provides an example on how to delete the exampleobject.txt object from the examplebucket bucket:
require 'aliyun/oss'
client = Aliyun::OSS::Client.new(
# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com.
endpoint: 'https://oss-cn-hangzhou.aliyuncs.com',
# Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured.
access_key_id: ENV['OSS_ACCESS_KEY_ID'],
access_key_secret: ENV['OSS_ACCESS_KEY_SECRET']
)
# Specify the name of the bucket. Example: examplebucket.
bucket = client.get_bucket('examplebucket')
# Specify the full path of the object. Example: exampledir/exampleobject.txt. Do not include the bucket name in the full path.
bucket.delete_object('exampledir/exampleobject.txt') Delete multiple objects
The following sample code provides an example on how to delete multiple specified objects:
require 'aliyun/oss'
client = Aliyun::OSS::Client.new(
# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com.
endpoint: 'https://oss-cn-hangzhou.aliyuncs.com',
# Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured.
access_key_id: ENV['OSS_ACCESS_KEY_ID'],
access_key_secret: ENV['OSS_ACCESS_KEY_SECRET']
)
# Specify the name of the bucket. Example: examplebucket.
bucket = client.get_bucket('examplebucket')
# Specify the full paths of the objects that you want to delete. Do not include the bucket name in the full paths.
objs = ['my-object-1', 'my-object-2']
result = bucket.batch_delete_objects(objs)
# By default, the information about deleted objects is returned.
puts result #['my-object-1', 'my-object-2']
objs = ['my-object-3', 'my-object-4']
result = bucket.batch_delete_objects(objs, :quiet => true)
# Specify that the information about deleted objects is not returned.
puts result #[] References
