Class Storage.PostPolicyV4Option (2.2.3)

Class for specifying Post Policy V4 options. *

Provides a service account signer to sign the policy. If not provided an attempt is made to get it from the environment.

Use a bucket-bound hostname, which replaces the storage.googleapis.com host with the name of a CNAME bucket, e.g. a bucket named 'gcs-subdomain.my.domain.tld', or a Google Cloud Load Balancer which routes to a bucket you own, e.g. 'my-load-balancer-domain.tld'. Note that this cannot be used alongside withVirtualHostedStyle() or withPathStyle(). This method signature uses HTTP for the URI scheme, and is equivalent to calling withBucketBoundHostname("...", UriScheme.HTTP).

Use a bucket-bound hostname, which replaces the storage.googleapis.com host with the name of a CNAME bucket, e.g. a bucket named 'gcs-subdomain.my.domain.tld', or a Google Cloud Load Balancer which routes to a bucket you own, e.g. 'my-load-balancer-domain.tld'. Note that this cannot be used alongside withVirtualHostedStyle() or withPathStyle(). The bucket name itself should not include the URI scheme (http or https), so it is specified via a local enum.

Generates a path-style URL, which places the bucket name in the path portion of the URL instead of in the hostname, e.g 'https://storage.googleapis.com/mybucket/...'. Note that this cannot be used alongside withVirtualHostedStyle(). Virtual hosted-style URLs, which can be used via the withVirtualHostedStyle() method, should generally be preferred instead of path-style URLs.

Use a virtual hosted-style hostname, which adds the bucket into the host portion of the URI rather than the path, e.g. 'https://mybucket.storage.googleapis.com/...'. The bucket name is obtained from the resource passed in.
