(Ruby) OSS List Bucket Objects (Alibaba Cloud)

See more Alibaba Cloud OSS Examples

Demonstrates how to list the objects in a bucket.

The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# This example assumes the Chilkat HTTP API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

# Insert your AccessKey ID here:
http.put_AwsAccessKey("access-key")

# Insert your AccessKey Secret here:
http.put_AwsSecretKey("secret-key")

# To list objects in a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
# See Alibaba Object Storage Service Regions and Endpoints
http.put_AwsEndpoint("oss-us-east-1.aliyuncs.com")

# If the response status code was not 200, then the XML response is not a 
# listing of objects, but instead contains error information.
