/**
* <p>Retrieves an object from Amazon S3.</p>
* <p>In the <code>GetObject</code> request, specify the full key name for the object.</p>
* <p>
* <b>General purpose buckets</b> - Both the virtual-hosted-style requests
* and the path-style requests are supported. For a virtual hosted-style request example, if you have the
* object <code>photos/2006/February/sample.jpg</code>, specify the object key name 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 object key name 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> in the <i>Amazon S3 User Guide</i>.</p>
* <p>
* <b>Directory buckets</b> -
* Only virtual-hosted-style requests are supported. For a virtual hosted-style request example, if you have the object <code>photos/2006/February/sample.jpg</code> in the bucket named <code>amzn-s3-demo-bucket--usw2-az1--x-s3</code>, specify the object key name as <code>/photos/2006/February/sample.jpg</code>. Also, when you make requests to this API operation, your requests are sent to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format <code>https://<i>bucket-name</i>.s3express-<i>zone-id</i>.<i>region-code</i>.amazonaws.com/<i>key-name</i>
* </code>. Path-style requests are not supported. For more information about endpoints in Availability Zones, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/endpoint-directory-buckets-AZ.html">Regional and Zonal endpoints for directory buckets in Availability Zones</a> in the
* <i>Amazon S3 User Guide</i>. For more information about endpoints in Local Zones, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-lzs-for-directory-buckets.html">Concepts for directory buckets in Local Zones</a> in the
* <i>Amazon S3 User Guide</i>.</p>
* <dl>
* <dt>Permissions</dt>
* <dd>
* <ul>
* <li>
* <p>
* <b>General purpose bucket permissions</b> - You must have the
* required permissions in a policy. To use <code>GetObject</code>, you must have the
* <code>READ</code> access to the object (or version). If you grant <code>READ</code> access
* to the anonymous user, the <code>GetObject</code> operation returns the object without using
* an authorization header. For more information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/using-with-s3-actions.html">Specifying permissions in a
* policy</a> in the <i>Amazon S3 User Guide</i>.</p>
* <p>If you include a <code>versionId</code> in your request header, you must have the
* <code>s3:GetObjectVersion</code> permission to access a specific version of an object. The
* <code>s3:GetObject</code> permission is not required in this scenario.</p>
* <p>If you request the current version of an object without a specific <code>versionId</code>
* in the request header, only the <code>s3:GetObject</code> permission is required. The
* <code>s3:GetObjectVersion</code> permission is not required in this scenario. </p>
* <p>If the object that you request doesn’t exist, the error that Amazon S3 returns depends on
* whether you also have the <code>s3:ListBucket</code> permission.</p>
* <ul>
* <li>
* <p>If you have the <code>s3:ListBucket</code> permission on the bucket, Amazon S3 returns an
* HTTP status code <code>404 Not Found</code> error.</p>
* </li>
* <li>
* <p>If you don’t have the <code>s3:ListBucket</code> permission, Amazon S3 returns an HTTP
* status code <code>403 Access Denied</code> error.</p>
* </li>
* </ul>
* </li>
* <li>
* <p>
* <b>Directory bucket permissions</b> - To grant access to this API operation on a directory bucket, we recommend that you use the <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html">
* <code>CreateSession</code>
* </a> API operation for session-based authorization. Specifically, you grant the <code>s3express:CreateSession</code> permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the <code>CreateSession</code> API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another <code>CreateSession</code> API call to generate a new session token for use.
* Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html">
* <code>CreateSession</code>
* </a>.</p>
* <p>If the object is
* encrypted using SSE-KMS, you must also have the <code>kms:GenerateDataKey</code> and
* <code>kms:Decrypt</code> permissions in IAM identity-based policies and KMS key policies
* for the KMS key.</p>
* </li>
* </ul>
* </dd>
* <dt>Storage classes</dt>
* <dd>
* <p>If the object you are retrieving is stored in the S3 Glacier Flexible Retrieval storage class,
* the S3 Glacier Deep Archive storage class, the S3 Intelligent-Tiering Archive Access tier, or the
* S3 Intelligent-Tiering Deep Archive Access tier, 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 operation 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> in the
* <i>Amazon S3 User Guide</i>.</p>
* <p>
* <b>Directory buckets </b> -
* Directory buckets only support <code>EXPRESS_ONEZONE</code> (the S3 Express One Zone storage class) in Availability Zones and <code>ONEZONE_IA</code> (the S3 One Zone-Infrequent Access storage class) in Dedicated Local Zones.
* Unsupported storage class values won't write a destination object and will respond with the HTTP status code <code>400 Bad Request</code>.</p>
* </dd>
* <dt>Encryption</dt>
* <dd>
* <p>Encryption request headers, like <code>x-amz-server-side-encryption</code>, should not be sent
* for the <code>GetObject</code> requests, if your object uses server-side encryption with Amazon S3
* managed encryption keys (SSE-S3), server-side encryption with Key Management Service (KMS) keys (SSE-KMS), or
* dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you include the header in
* your <code>GetObject</code> requests for the object that uses these types of keys, you’ll get an
* HTTP <code>400 Bad Request</code> error.</p>
* <p>
* <b>Directory buckets</b> -
* For directory buckets, there are only two supported options for server-side encryption: SSE-S3 and SSE-KMS. SSE-C isn't supported. For more
* information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-serv-side-encryption.html">Protecting data with server-side encryption</a> in the <i>Amazon S3 User Guide</i>.</p>
* </dd>
* <dt>Overriding response header values through the request</dt>
* <dd>
* <p>There are times when you want to override certain response header values of a
* <code>GetObject</code> response. For example, you might override the
* <code>Content-Disposition</code> response header value through your <code>GetObject</code>
* request.</p>
* <p>You can override values for a set of response headers. These modified response header values
* are included only in a successful response, that is, when the HTTP status code <code>200 OK</code>
* is returned. The headers you can override using the following query parameters in the request are
* a subset of the headers that Amazon S3 accepts when you create an object. </p>
* <p>The response headers that you can override for the <code>GetObject</code> response are
* <code>Cache-Control</code>, <code>Content-Disposition</code>, <code>Content-Encoding</code>,
* <code>Content-Language</code>, <code>Content-Type</code>, and <code>Expires</code>.</p>
* <p>To override values for a set of response headers in the <code>GetObject</code> response, you
* can use the following query parameters in the request.</p>
* <ul>
* <li>
* <p>
* <code>response-cache-control</code>
* </p>
* </li>
* <li>
* <p>
* <code>response-content-disposition</code>
* </p>
* </li>
* <li>
* <p>
* <code>response-content-encoding</code>
* </p>
* </li>
* <li>
* <p>
* <code>response-content-language</code>
* </p>
* </li>
* <li>
* <p>
* <code>response-content-type</code>
* </p>
* </li>
* <li>
* <p>
* <code>response-expires</code>
* </p>
* </li>
* </ul>
* <note>
* <p>When you use these parameters, you must sign the request by using either an Authorization
* header or a presigned URL. These parameters cannot be used with an unsigned (anonymous)
* request.</p>
* </note>
* </dd>
* <dt>HTTP Host header syntax</dt>
* <dd>
* <p>
* <b>Directory buckets </b> - The HTTP Host header syntax is <code>
* <i>Bucket-name</i>.s3express-<i>zone-id</i>.<i>region-code</i>.amazonaws.com</code>.</p>
* </dd>
* </dl>
* <p>The following operations are related to <code>GetObject</code>:</p>

* <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObjectAcl.html">GetObjectAcl</a>
* </p>
* </li>
* </ul>
* <important>
* <p>You must URL encode any signed header values that contain spaces. For example, if your header value is <code>my file.txt</code>, containing two spaces after <code>my</code>, you must URL encode this value to <code>my%20%20file.txt</code>.</p>
