Getting Objects
Topics
You can retrieve objects directly from Amazon S3. You have the following options when retrieving an object:
Retrieve an entire object—A single GET operation can return you the entire object stored in Amazon S3.
Retrieve object in parts—Using the
RangeHTTP header in a GET request, you can retrieve a specific range of bytes in an object stored in Amazon S3.You resume fetching other parts of the object whenever your application is ready. This resumable download is useful when you need only portions of your object data. It is also useful where network connectivity is poor and you need to react to failures.
When you retrieve an object, its metadata is returned in the response headers. There are
times when you want to override certain response header values returned in a GET
response. For example, you might override the Content-Disposition response
header value in your GET request. The REST GET Object API (see GET
Object) allows you to specify query string parameters in your GET request to
override these values. The AWS SDK for Java, .NET and PHP also provide necessary objects
you can use to specify values for these response headers in your GET request.
