BlobServiceSasSignatureValues Class

Package:

com.azure.storage.blob.sas

Maven Artifact:

com.azure:azure-storage-blob:12.28.1

• java.lang.Object
• • com.azure.storage.blob.sas.BlobServiceSasSignatureValues

public final class BlobServiceSasSignatureValues

Used to initialize parameters for a Shared Access Signature (SAS) for an Azure Blob Storage service. Once all the values here are set, use the appropriate SAS generation method on the desired container/blob client to obtain a representation of the SAS which can then be applied to a new client using the .sasToken(String) method on the desired client builder.

Method Details

generateSasQueryParameters

@Deprecated
public BlobServiceSasQueryParameters generateSasQueryParameters(UserDelegationKey delegationKey, String accountName)

Deprecated

Please use the generateUserDelegationSas(BlobServiceSasSignatureValues, UserDelegationKey) method on the desired container/blob client after initializing BlobServiceSasSignatureValues.

Uses a user delegation key to sign these signature values to produce the proper SAS query parameters.

Notes on SAS generation

• If setIdentifier(String identifier) is set, setExpiryTime(OffsetDateTime expiryTime) and permissions should not be set. These values are inherited from the stored access policy.
• Otherwise, setExpiryTime(OffsetDateTime expiryTime) and getPermissions() must be set.

The type of SAS query parameters returned depends on the following:

1. If getBlobName() is not set, container SAS query parameters are returned.
2. If getBlobName() and getSnapshotId() are set, blob snapshot SAS query parameters are returned.
3. If only getBlobName() is set, blob SAS query parameters are returned.

See class level JavaDocs for code snippets.

Parameters:

delegationKey - A UserDelegationKey object used to sign the SAS values.

accountName - Azure Storage account name to generate SAS for.
