IBMStorage Class

Properties   Methods   Events   Configuration Settings   Errors  

The IBMStorage class provides an easy way to interface with IBM Cloud's Object Storage service.




The IBM Cloud Object Storage service has an API that is compatible with that of Amazon S3, allowing you to store arbitrary data using the same bucket-and-object paradigm that S3 uses.

To use the IBMStorage class, you will first need to sign up for the IBM Cloud Object Storage service and obtain an AccessKey and a SecretKey. Then you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.

There are other methods such as ListBuckets, ListObjects, GetObject, GetLink, DeleteObject etc. that further enable you to manage your data store.
