Public Class BlobSasBuilder

Inheritance

Object

BlobSasBuilder

Constructors

BlobSasBuilder(BlobContainerSasPermissions, DateTimeOffset)	Initializes a new instance of the BlobSasBuilder class to create a Blob Container Service Sas.
BlobSasBuilder(BlobSasPermissions, DateTimeOffset)	Initializes a new instance of the BlobSasBuilder class to create a Blob Service Sas.

Properties

BlobContainerName	The name of the blob container being made accessible.
BlobName	The name of the blob being made accessible, or Empty for a container SAS.
BlobVersionId	The name of the blob version being made accessible, or Empty for a blob SAS.
CacheControl	Override the value returned for Cache-Control response header.
ContentDisposition	Override the value returned for Content-Disposition response header.
ContentEncoding	Override the value returned for Content-Encoding response header.
ContentLanguage	Override the value returned for Content-Language response header.
ContentType	Override the value returned for Content-Type response header.
CorrelationId	Optional. Beginning in version 2020-02-10, this value will be used for to correlate the storage audit logs with the audit logs used by the principal generating and distributing SAS. This is only used for User Delegation SAS.
EncryptionScope	Optional. Encryption scope to use when sending requests authorized with this SAS URI.
ExpiresOn	The time at which the shared access signature becomes invalid. This field must be omitted if it has been specified in an associated stored access policy.
Identifier	An optional unique value up to 64 characters in length that correlates to an access policy specified for the container.
IPRange	Specifies an IP address or a range of IP addresses from which to accept requests. If the IP address from which the request originates does not match the IP address or address range specified on the SAS token, the request is not authenticated. When specifying a range of IP addresses, note that the range is inclusive.
Permissions	The permissions associated with the shared access signature. The user is restricted to operations allowed by the permissions. This field must be omitted if it has been specified in an associated stored access policy. The BlobSasPermissions, BlobContainerSasPermissions, SnapshotSasPermissions, or BlobAccountSasPermissions can be used to create the permissions string.
PreauthorizedAgentObjectId	Optional. Beginning in version 2020-02-10, this value will be used for the AAD Object ID of a user authorized by the owner of the User Delegation Key to perform the action granted by the SAS. The Azure Storage service will ensure that the owner of the user delegation key has the required permissions before granting access. No additional permission check for the user specified in this value will be performed. This is only used with generating User Delegation SAS.
Protocol	The optional signed protocol field specifies the protocol permitted for a request made with the SAS. Possible values are HttpsAndHttp, Https, and None.
Resource	Specifies which resources are accessible via the shared access signature. Specify "b" if the shared resource is a blob. This grants access to the content and metadata of the blob. Specify "c" if the shared resource is a blob container. This grants access to the content and metadata of any blob in the container, and to the list of blobs in the container. Beginning in version 2018-11-09, specify "bs" if the shared resource is a blob snapshot. This grants access to the content and metadata of the specific snapshot, but not the corresponding root blob. Beginning in version 2019-12-12, specify "bv" if the shared resource is a blob version. This grants access to the content and metadata of the specific version, but not the corresponding root blob.
Snapshot	The name of the snapshot being made accessible, or Empty for a blob SAS.
StartsOn	Optionally specify the time at which the shared access signature becomes valid. If omitted when DateTimeOffset.MinValue is used, start time for this call is assumed to be the time when the storage service receives the request.
