Description

Object interface for Amazon S3 API Version 2006-03-01 http://docs.amazonwebservices.com/AmazonS3/2006-03-01/

Synopsis

Function Types

sendObjectSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to add to a bucket

-> IO (AWSResult ())

Server response

Send data for an object.

copyObjectSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Source object (bucket+name only)

-> S3Object

Destination object

-> IO (AWSResult S3Object)

Server response, headers include version information

Copy object from one bucket to another (or the same bucket), preserving the original headers. Headers from destobj are sent, while only the bucket and name of srcobj are used. For the best performance, when changing headers during a copy, use the copyObjectWithReplace function. For conditional copying, the following headers set on the destination object may be used: x-amz-copy-source-if-match, x-amz-copy-source-if-none-match, x-amz-copy-source-if-unmodified-since, or x-amz-copy-source-if-modified-since. See http://docs.amazonwebservices.com/AmazonS3/2006-03-01/API/index.html?RESTObjectCOPY.html for more details.

copyObjectWithReplaceSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Source object (bucket+name only)

-> S3Object

Destination object

-> IO (AWSResult S3Object)

Server response, headers include version information

Copy object from one bucket to another (or the same bucket), replacing headers. Any headers from srcobj are ignored, and only those set in destobj are used.

getObjectSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to retrieve

-> IO (AWSResult S3Object)

Server response

Retrieve an object.

getObjectInfoSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to retrieve information on

-> IO (AWSResult S3Object)

Server response

Get object info without retrieving content body from server.

deleteObjectSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to delete

-> IO (AWSResult ())

Server response

Delete an object. Only bucket and object name need to be specified in the S3Object. Deletion of a non-existent object does not return an error.

publicUriForSecondsSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to be made available

-> Integer

How many seconds until this request expires

-> IO URI

URI for the object

Create a pre-signed request URI. Anyone can use this to request an object for the number of seconds specified.

publicUriUntilTimeSource

Arguments

:: AWSConnection

AWS connection information

-> S3Object

Object to be made available

-> Integer

Expiration time, in seconds since 00:00:00 UTC on January 1, 1970

-> URI

URI for the object

Create a pre-signed request URI. Anyone can use this to request an object until the specified date.

setStorageClassSource

Arguments

:: StorageClass

Storage class to request

-> S3Object

Object to modify

-> S3Object

Object with storage class headers set, ready to be sent

Add required headers for the storage class. Use this in combination with sendObject for new objects. To modify the storage class of existing objects, use rewriteStorageClass. Using reduced redundancy for object storage trades off redundancy for storage costs.

getStorageClassSource

Arguments

:: S3Object

Object to inspect

-> Maybe StorageClass

Requested storage class, Nothing if unspecified

Retrieve the storage class of a local S3Object. Does not work for objects retrieved with getObject, since the required header values are not returned. Use getObjectStorageClass or listObjects from S3Bucket module to determine storage class of existing objects.

rewriteStorageClassSource

Arguments

:: AWSConnection

AWS connection information

-> StorageClass

New storage class for object

-> S3Object

Object to modify

-> IO (AWSResult S3Object)

Server response

Change the storage class (and only the storage class) of an existing object. This actually performs a copy to the same location, preserving metadata. It is not clear to me whether ACLs are preserved when copying to the same location. For best performance, we must not change other headers during storage class changes.

Data Types

data S3Object Source

An object that can be stored and retrieved from S3.

Constructors

S3Object 

Fields

obj_bucket :: String

Name of the bucket containing this object

obj_name :: String

URI of the object. Subresources (?acl or | ?torrent) should be suffixed onto this name.

content_type :: String

A standard MIME type describing the format of the contents. If not specified, binary/octet-stream is used.

obj_headers :: [(String, String)]

Object metadata in (key,value) pairs. Key names should use the prefix x-amz-meta- to be stored with the object. The total HTTP request must be under 4KB, including these headers.

obj_data :: ByteString

Object data.
