Google Cloud Storage

Google Cloud Storage

4WS.Platform is integrated with Google Cloud Platform, in particular with Google Cloud Storage. To enable this integration a Service Account must be defined in the Google Cloud Console and the following parameters must be specified:

  • GOOGLE_SERVACC_EMAIL: the service account email address

  • GOOGLE_SERVACC_KEY: the service account p12 public key, Base64 encoded

The available Javascript actions are the following

Get a signed URL

To get a signed URL for Google Cloud Storage operations (refer to the official documentation for details: https://cloud.google.com/storage/docs/access-control#Signed-URLs).

Syntax

utils.getGoogleCloudStorageSignedURL(verb,expiration, bucketName, objectName, mime)

Details

verb – one of ‘GET’, ‘HEAD’, PUT‘’, ‘DELETE’ expiration – This is the timestamp (represented as the number of seconds since the Unix Epoch of 00:00:00 UTC on January 1, 1970) when the signature expires. The server will reject any requests received after this timestamp bucketName – the name of the bucket which we want to operate on objectName – the name of the object mime – the MIME type of the resource. Can be null. Return value - A string containing the signed URL.

Get information about a bucket

Syntax

utils.getGoogleCloudStorageBucket(bucketName)

Details

bucketName – the name of the bucket which we want to operate on Return value - The file container representation (org.wag.valueobjects.java.FileContainer)

Create a bucket

Syntax

utils.createGoogleCloudBucket(project, bucketName, bucketLocation, storageClass)

Details

project – the id of the Google Developer Console project where the bucket must be created bucketName – the name of the bucket which we want to operate on bucketLocation – the location of the bucket. Multi-region location: US, EU, ASIA. Other locations are supported. See https://cloud.google.com/storage/docs/ storageClass – (optional) storage class: STANDARD, NEARLINE and DURABLE_REDUCED_AVAILABILITY. See https://cloud.google.com/storage/ Return value - the file container representation (org.wag.valueobjects.java.FileContainer)

Delete a bucket

Syntax

utils.deleteGoogleCloudStorageBucket(bucketName)

Details

bucketName – the name of the bucket which we want to operate on Return value - the file container representation (org.wag.valueobjects.java.FileContainer)

Enable or disable the object versioning of a bucket

Syntax

utils.setGoogleCloudStorageBucketVersioning(bucketName,versioning)

Details

bucketName – the name of the bucket which we want to operate on versioning – true or false. Whether to enable or disable versioning Return value - The file container representation (org.wag.valueobjects.java.FileContainer)

Check if the object versioning of a bucket is enabled

Syntax

utils.getGoogleCloudStorageBucketVersioning(bucketName)

Details

bucketName – the name of the bucket which we want to operate on Return value - true or false

Upload a file from server file system to Cloud Storage

Syntax

utils.uploadGoogleCloudStorageObjectFromFS(fsPath, bucketName, objectName, deleteFsFile)

Details

fsPath – the path on the file system where the file is located bucketName – the name of the bucket which we want to upload the file to objectName – the name of the object, with the full path deleteFsFile – whether or not delete the file from file system after upload Return value - the file representation (org.wag.valueobjects.java.File)

Copy an object and its metadata to a new bucket and object destination

Can be used to copy between buckets with the same location and type. Can choose to copy from a specific object version if bucket versioning is enabled.

Syntax

utils.copyGoogleCloudStorageObject(sourceBucketName, sourceObjectName, sourceObjectVersion, destinationBucketName, destinationObjectName)

Details

sourceBucketName – the bucket of the source object sourceObjectName – the source object name, with full path sourceObjectVersion – (optional). The object version to copy. Can be null. destinationBucketName – the destination bucket destinationObjectName – the destination object name, with full path Return value - the file representation (org.wag.valueobjects.java.File)

Copy an object and its metadata to a new bucket and object destination

Must be used to copy objects between regions and bucket types. Can choose to copy from a specific object version if bucket versioning is enabled

Syntax

utils.rewriteGoogleCloudStorageObject(sourceBucketName, sourceObjectName, sourceObjectVersion, destinationBucketName, destinationObjectName)

Details

sourceBucketName – the bucket of the source object sourceObjectName – the source object name, with full path sourceObjectVersion – (optional). The object version to copy. Can be null. destinationBucketName – the destination bucket destinationObjectName – the destination object name, with full path Return value - the file representation (org.wag.valueobjects.java.File)

Delete an object from a bucket

Syntax

utils.deleteGoogleCloudStorageObject(bucketName,objectName)

Details

bucketName – the bucket of the object objectName – the object name, with full path

Get object information from a bucket

Syntax

utils.getGoogleCloudStorageObject(bucketName,objectName)

Details

bucketName – the bucket of the object objectName – the object name, with full path Return value - the file representation (org.wag.valueobjects.java.File)

Get a list of versions of the object from a bucket

Syntax

utils.getGoogleCloudStorageObjectVersions(bucketName,objectName)

Details

bucketName – the bucket of the object objectName – the object name, with full path Return value - A list of the file version representation objects (org.wag.valueobjects.java.FileVersion)

Get a list of all the objects stored in a bucket

Possibly filtered by a prefix and a delimiter. See https://cloud.google.com/storage/docs/json_api/v1/objects/list

Syntax

utils.getGoogleCloudStorageObjectVersions(bucketName,prefix,delimiter)

Details

bucketName – the bucket of the object prefix – the prefix to filter the objects delimiter – the path delimiter Return value - A list of the file representation objects (org.wag.valueobjects.java.File)

Get a paginated list of the objects stored in a bucket

Possibly filtered by a prefix and a delimiter. See https://cloud.google.com/storage/docs/json_api/v1/objects/list. The next page token can be used to retrieve more pages, maxPageResults to manage page size and pages to specify how many pages to load.

Syntax

utils.listGoogleCloudStorageObjects(bucketName, maxPageResults, pages, nextPageToken, prefix, delimiter)

Details

bucketName – the bucket of the object maxPageResults – max results to load per page. Can be null pages – max pages to load. Can be null nextPageToken – the token for pagination prefix – the prefix to filter the objects delimiter – the path delimiter Return value - A GooglePaginatedList (org.wag.valueobjects.java.GooglePaginatedList) of the file representation objects (org.wag.valueobjects.java.File)
