You can use the Aws\S3\S3Client::upload() method if you just want to upload files and not worry if they are
too large to send in a single PutObject operation or require a multipart upload.
$client->upload('bucket', 'key', 'object body', 'public-read');
Setting ACLs and Access Control Policies
You can specify a canned ACL on an object when uploading:
$client->putObject(array(
'Bucket' => 'mybucket',
'Key' => 'data.txt',
'SourceFile' => '/path/to/data.txt',
'ACL' => 'public-read'
));
You can use the Aws\S3\Enum\CannedAcl object to provide canned ACL constants:
use Aws\S3\Enum\CannedAcl;
$client->putObject(array(
'Bucket' => 'mybucket',
'Key' => 'data.txt',
'SourceFile' => '/path/to/data.txt',
'ACL' => CannedAcl::PUBLIC_READ
));
You can specify more complex ACLs using the ACP parameter when sending PutObject, CopyObject,
CreateBucket, CreateMultipartUpload, PutBucketAcl, PutObjectAcl, and other operations that accept a canned ACL.
Using the ACP parameter allows you specify more granular access control policies using a Aws\S3\Model\Acp
object. The easiest way to create an Acp object is through the Aws\S3\Model\AcpBuilder.
use Aws\S3\Enum\Permission;
use Aws\S3\Enum\Group;
use Aws\S3\Model\AcpBuilder;
$acp = AcpBuilder::newInstance()
->setOwner($myOwnerId)
->addGrantForEmail(Permission::READ, '[e-mail]')
->addGrantForUser(Permission::FULL_CONTROL, 'user-id')
->addGrantForGroup(Permission::READ, Group::AUTHENTICATED_USERS)
->build();
$client->putObject(array(
'Bucket' => 'mybucket',
'Key' => 'data.txt',
'SourceFile' => '/path/to/data.txt',
'ACP' => $acp
));
Creating a pre-signed URL
You can authenticate certain types of requests by passing the required information as query-string parameters
instead of using the Authorization HTTP header. This is useful for enabling direct third-party browser access to your
private Amazon S3 data, without proxying the request. The idea is to construct a "pre-signed" request and encode it
as a URL that an end-user's browser can retrieve. Additionally, you can limit a pre-signed request by specifying an
expiration time.
