如何使用s3图像url删除s3对象？

Question

我想通过查找下面的网址从s3存储桶中删除图像。

 https://s3-ap-southeast-1.amazonaws.com/s3dev-bucket/perspectives/images/3547/original/1.jpg?1471239691 

Answer 1

使用#delete_object() ：

resp = client.delete_object({
  bucket: "s3dev-bucket", 
  key: "perspectives/images/3547/original/1.jpg", 
})

Answer 2

你必须使用aws-sdk-s3 gem。 @John已经回答了它，帮助你，这里是S3创建对象ruby代码的示例。 您必须更改函数调用才能删除该对象。

require 'aws-sdk-s3'  # v2: require 'aws-sdk'

s3 = Aws::S3::Resource.new(region: 'us-west-2')

file = 'C:\file.txt'
bucket = 'my-bucket'

# Get just the file name
name = File.basename(file)

# Create the object to upload
obj = s3.bucket(bucket).object(name)

# Upload it      
obj.upload_file(file)

你可以这样试试

Aws.config.update(
credentials: Aws::Credentials.new("access_key_id", "secret_access_key"),
region: "region"
)

s3 = Aws::S3::Resource.new.bucket("bucket")
obj = s3.object('perspectives/images/3547/original/1.jpg')
obj.delete
