 * <p>Retrieves objects from Amazon S3. To use <code>GET</code>, you must have <code>READ</code>
 *          access to the object. If you grant <code>READ</code> access to the anonymous user, you can
 *          return the object without using an authorization header.</p>
 *          <p>An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer
 *          file system. You can, however, create a logical hierarchy by using object key names that
 *          imply a folder structure. For example, instead of naming an object <code>sample.jpg</code>,
 *          you can name it <code>photos/2006/February/sample.jpg</code>.</p>
 *          <p>To get an object from such a logical hierarchy, specify the full key name for the object
 *          in the <code>GET</code> operation. For a virtual hosted-style request example, if you have
 *          the object <code>photos/2006/February/sample.jpg</code>, specify the resource as
 *             <code>/photos/2006/February/sample.jpg</code>. For a path-style request example, if you
 *          have the object <code>photos/2006/February/sample.jpg</code> in the bucket named
 *             <code>examplebucket</code>, specify the resource as
 *             <code>/examplebucket/photos/2006/February/sample.jpg</code>. For more information about
 *          request types, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html#VirtualHostingSpecifyBucket">HTTP Host
 *             Header Bucket Specification</a>.</p>
 *          <p>For more information about returning the ACL of an object, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObjectAcl.html">GetObjectAcl</a>.</p>
 *          <p>If the object you are retrieving is stored in the S3 Glacier Flexible Retrieval or
 *          S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or
 *          S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a
 *          copy using <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_RestoreObject.html">RestoreObject</a>. Otherwise, this action returns an
 *             <code>InvalidObjectState</code> error. For information about restoring archived objects,
 *          see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/restoring-objects.html">Restoring
 *             Archived Objects</a>.</p>
 *          <p>Encryption request headers, like <code>x-amz-server-side-encryption</code>, should not
 *          be sent for GET requests if your object uses server-side encryption with Key Management Service (KMS)
 *          keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or
 *          server-side encryption with Amazon S3 managed encryption keys (SSE-S3). If your object does use
 *          these types of keys, you’ll get an HTTP 400 Bad Request error.</p>
 *          <p>If you encrypt an object by using server-side encryption with customer-provided
 *          encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object,
 *          you must use the following headers:</p>
 *          <ul>
 *             <li>
 *                <p>
 *                   <code>x-amz-server-side-encryption-customer-algorithm</code>

 *             (Using Customer-Provided Encryption Keys)</a>.</p>
 *          <p>Assuming you have the relevant permission to read object tags, the response also returns
 *          the <code>x-amz-tagging-count</code> header that provides the count of number of tags
 *          associated with the object. You can use <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObjectTagging.html">GetObjectTagging</a> to retrieve

 *             <dd>
 *                <p>There are times when you want to override certain response header values in a <code>GET</code>
 *                   response. For example, you might override the <code>Content-Disposition</code> response
 *          header value in your <code>GET</code> request.</p>
 *                <p>You can override values for a set of response headers using the following query
 *                   parameters. These response header values are sent only on a successful request, that is,
 *                   when status code 200 OK is returned. The set of headers you can override using these
 *                   parameters is a subset of the headers that Amazon S3 accepts when you create an object. The
 *                   response headers that you can override for the <code>GET</code> response are <code>Content-Type</code>,
 *                   <code>Content-Language</code>, <code>Expires</code>, <code>Cache-Control</code>,
 *                   <code>Content-Disposition</code>, and <code>Content-Encoding</code>. To override these
 *                   header values in the <code>GET</code> response, you use the following request parameters.</p>
 *                <note>
 *                   <p>You must sign the request, either using an Authorization header or a presigned URL,
 *                      when using these parameters. They cannot be used with an unsigned (anonymous)
 *                      request.</p>
