Properties

Optional acceptRanges

acceptRanges: undefined | string

Indicates that the service supports requests for partial blob content.

Optional blobCommittedBlockCount

blobCommittedBlockCount: undefined | number

The number of committed blocks present in the blob. This header is returned only for append blobs.

Optional blobContentMD5

blobContentMD5: Uint8Array

If the blob has a MD5 hash, and if request contains range header (Range or x-ms-range), this response header is returned with the value of the whole blob's MD5 value. This value may or may not be equal to the value returned in Content-MD5 header, with the latter calculated from the requested range

Optional blobSequenceNumber

blobSequenceNumber: undefined | number

The current sequence number for a page blob. This header is not returned for block blobs or append blobs

Optional blobType

blobType: BlobType

The blob's type. Possible values include: 'BlockBlob', 'PageBlob', 'AppendBlob'

Optional cacheControl

cacheControl: undefined | string

This header is returned if it was previously specified for the blob.

Optional clientRequestId

clientRequestId: undefined | string

If a client request id header is sent in the request, this header will be present in the response with the same value.

Optional contentCrc64

contentCrc64: Uint8Array

If the request is to read a specified range and the x-ms-range-get-content-crc64 is set to true, then the request returns a crc64 for the range, as long as the range size is less than or equal to 4 MB. If both x-ms-range-get-content-crc64 and x-ms-range-get-content-md5 is specified in the same request, it will fail with 400(Bad Request)

Optional contentDisposition

contentDisposition: undefined | string

This header returns the value that was specified for the 'x-ms-blob-content-disposition' header. The Content-Disposition response header field conveys additional information about how to process the response payload, and also can be used to attach additional metadata. For example, if set to attachment, it indicates that the user-agent should not display the response, but instead show a Save As dialog with a filename other than the blob name specified.

Optional contentEncoding

contentEncoding: undefined | string

This header returns the value that was specified for the Content-Encoding request header

Optional contentLanguage

contentLanguage: undefined | string

This header returns the value that was specified for the Content-Language request header.

Optional contentLength

contentLength: undefined | number

The number of bytes present in the response body.

Optional contentMD5

contentMD5: Uint8Array

If the blob has an MD5 hash and this operation is to read the full blob, this response header is returned so that the client can check for message content integrity.

Optional contentRange

contentRange: undefined | string

Indicates the range of bytes returned in the event that the client requested a subset of the blob by setting the 'Range' request header.

Optional contentType

contentType: undefined | string

The media type of the body of the response. For Download Blob this is 'application/octet-stream'

Optional copyCompletionTime

copyCompletionTime: Date

Conclusion time of the last attempted Copy Blob operation where this blob was the destination blob. This value can specify the time of a completed, aborted, or failed copy attempt. This header does not appear if a copy is pending, if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List.

Optional copyId

copyId: undefined | string

String identifier for this copy operation. Use with Get Blob Properties to check the status of this copy operation, or pass to Abort Copy Blob to abort a pending copy.

Optional copyProgress

copyProgress: undefined | string

Contains the number of bytes copied and the total bytes in the source in the last attempted Copy Blob operation where this blob was the destination blob. Can show between 0 and Content-Length bytes copied. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List

Optional copySource

copySource: undefined | string

URL up to 2 KB in length that specifies the source blob or file used in the last attempted Copy Blob operation where this blob was the destination blob. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List.

Optional copyStatus

copyStatus: CopyStatusType

State of the copy operation identified by x-ms-copy-id. Possible values include: 'pending', 'success', 'aborted', 'failed'

Optional copyStatusDescription

copyStatusDescription: undefined | string

Only appears when x-ms-copy-status is failed or pending. Describes the cause of the last fatal or non-fatal copy operation failure. This header does not appear if this blob has never been the destination in a Copy Blob operation, or if this blob has been modified after a concluded Copy Blob operation using Set Blob Properties, Put Blob, or Put Block List

Optional date

date: Date

UTC date/time value generated by the service that indicates the time at which the response was initiated

Optional encryptionKeySha256

encryptionKeySha256: undefined | string

The SHA-256 hash of the encryption key used to encrypt the blob. This header is only returned when the blob was encrypted with a customer-provided key.

Optional encryptionScope

encryptionScope: undefined | string

Returns the name of the encryption scope used to encrypt the blob contents and application metadata. Note that the absence of this header implies use of the default account encryption scope.

Optional errorCode

errorCode: undefined | string

Optional etag

etag: undefined | string

The ETag contains a value that you can use to perform operations conditionally. If the request version is 2011-08-18 or newer, the ETag value will be in quotes.

Optional isServerEncrypted

isServerEncrypted: undefined | false | true

The value of this header is set to true if the blob data and application metadata are completely encrypted using the specified algorithm. Otherwise, the value is set to false (when the blob is unencrypted, or if only parts of the blob/application metadata are encrypted).

Optional lastModified

lastModified: Date

Returns the date and time the container was last modified. Any operation that modifies the blob, including an update of the blob's metadata or properties, changes the last-modified time of the blob.

Optional leaseDuration

leaseDuration: LeaseDurationType

When a blob is leased, specifies whether the lease is of infinite or fixed duration. Possible values include: 'infinite', 'fixed'

Optional leaseState

leaseState: LeaseStateType

Lease state of the blob. Possible values include: 'available', 'leased', 'expired', 'breaking', 'broken'

Optional leaseStatus

leaseStatus: LeaseStatusType

The current lease status of the blob. Possible values include: 'locked', 'unlocked'

Optional metadata

metadata: undefined | {}

Optional requestId

requestId: undefined | string

This header uniquely identifies the request that was made and can be used for troubleshooting the request.

Optional version

version: undefined | string

Indicates the version of the Blob service used to execute the request. This header is returned for requests made against version 2009-09-19 and above.
