# Akeeba Amazon S3 Connector
A compact, dependency-less Amazon S3 API client implementing the most commonly used features
## Why reinvent the wheel
After having a lot of impossible to debug problems with Amazon's Guzzle-based AWS SDK we decided to roll our own connector for Amazon S3. This is by no means a complete implementation, just a small subset of S3's features which are required by our software. The design goals are simplicity, no external dependencies and low memory footprint.
This code was originally based on [S3.php written by Donovan Schonknecht](http://undesigned.org.za/2007/10/22/amazon-s3-php-class) which is available under a BSD-like license. This repository no longer reflects the original author's work and should not be confused with it.
This software is distributed under the GNU General Public License version 3 or, at your option, any later version published by the Free Software Foundation (FSF). In short, it's "GPLv3+".
## Important note about version 2
Akeeba Amazon S3 Connector version 2 has dropped support for PPH 5.3 to 7.0 inclusive. It is only compatible with PHP 7.1 or later, up to and including PHP 8.0.
The most significant change in this version is that all methods use scalar type hints for parameters and return values. This _may_ break existing consumers which relied on implicit type conversion e.g. passing strings containing integer values instead of _actual_ integer values.
## Using the connector
### Get a connector object
```php
$configuration = new \Akeeba\Engine\Postproc\Connector\S3v4\Configuration(
'YourAmazonAccessKey',
'YourAmazonSecretKey'
);
$connector = new \Akeeba\Engine\Postproc\Connector\S3v4\Connector($configuration);
```
If you are running inside an Amazon EC2 instance you can fetch temporary credentials from the instance's metadata
server using the IAM Role attached to the EC2 instance. In this case you need to do this (169.254.169.254 is a fixed
IP hosting the instance's metadata cache service):
```php
$role = file_get_contents('http://169.254.169.254/latest/meta-data/iam/security-credentials/');
$jsonCredentials = file_get_contents('http://169.254.169.254/latest/meta-data/iam/security-credentials/' . $role);
$credentials = json_decode($jsonCredentials, true);
$configuration = new \Akeeba\Engine\Postproc\Connector\S3v4\Configuration(
$credentials['AccessKeyId'],
$credentials['SecretAccessKey'],
'v4',
$yourRegion
);
$configuration->setToken($credentials['Token']);
$connector = new \Akeeba\Engine\Postproc\Connector\S3v4\Connector($configuration);
```
where `$yourRegion` is the AWS region of your bucket, e.g. `us-east-1`. Please note that we are passing the security
token (`$credentials['Token']`) to the Configuration object. This is REQUIRED. The temporary credentials returned by
the metadata service won't work without it.
Also worth noting is that the temporary credentials don't last forever. Check the `$credentials['Expiration']` to see
when they are about to expire. Amazon recommends that you retry fetching new credentials from the metadata service
10 minutes before your cached credentials are set to expire. The metadata service is guaranteed to provision fresh
temporary credentials by that time.
### Listing buckets
```php
$listing = $connector->listBuckets(true);
```
Returns an array like this:
```
array(2) {
'owner' =>
array(2) {
'id' =>
string(64) "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
'name' =>
string(8) "someUserName"
}
'buckets' =>
array(3) {
[0] =>
array(2) {
'name' =>
string(10) "mybucket"
'time' =>
int(1267730711)
}
[1] =>
array(2) {
'name' =>
string(10) "anotherbucket"
'time' =>
int(1269516249)
}
[2] =>
array(2) {
'name' =>
string(11) "differentbucket"
'time' =>
int(1354458048)
}
}
}
```
### Listing bucket contents
```php
$listing = $connector->getBucket('mybucket', 'path/to/list/');
```
If you want to list "subdirectories" you need to do
```php
$listing = $connector->getBucket('mybucket', 'path/to/list/', null, null, '/', true);
```
The last parameter (common prefixes) controls the listing of "subdirectories"
### Uploading (small) files
From a file:
```php
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromFile($sourceFile);
$connector->putObject($input, 'mybucket', 'path/to/myfile.txt');
```
From a string:
```php
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromData($sourceString);
$connector->putObject($input, 'mybucket', 'path/to/myfile.txt');
```
From a stream resource:
```php
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromResource($streamHandle, false);
$connector->putObject($input, 'mybucket', 'path/to/myfile.txt');
```
In all cases the entirety of the file has to be loaded in memory.
### Uploading large file with multipart (chunked) uploads
Files are uploaded in 5Mb chunks.
```php
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromFile($sourceFile);
$uploadId = $connector->startMultipart($input, 'mybucket', 'mypath/movie.mov');
$eTags = array();
$eTag = null;
$partNumber = 0;
do
{
// IMPORTANT: You MUST create the input afresh before each uploadMultipart call
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromFile($sourceFile);
$input->setUploadID($uploadId);
$input->setPartNumber(++$partNumber);
$eTag = $connector->uploadMultipart($input, 'mybucket', 'mypath/movie.mov');

// IMPORTANT: You MUST create the input afresh before finalising the multipart upload
$input = \Akeeba\Engine\Postproc\Connector\S3v4\Input::createFromFile($sourceFile);
$input->setUploadID($uploadId);
$input->setEtags($eTags);
$connector->finalizeMultipart($input, 'mybucket', 'mypath/movie.mov');
```
As long as you keep track of the UploadId, PartNumber and ETags you can have each uploadMultipart call in a separate
page load to prevent timeouts.
### Get presigned URLs
Allows browsers to download files directly without exposing your credentials and without going through your server:
```php
$preSignedURL = $connector->getAuthenticatedURL('mybucket', 'path/to/file.jpg', 60);
```
The last parameter controls how many seconds into the future this URL will be valid.
### Download
To a file with absolute path `$targetFile`
```php
$connector->getObject('mybucket', 'path/to/file.jpg', $targetFile);
```
To a string
```php
$content = $connector->getObject('mybucket', 'path/to/file.jpg', false);
```
### Delete an object
```php
$connector->deleteObject('mybucket', 'path/to/file.jpg');
```
## Configuration options
The Configuration option has optional methods which can be used to enable some useful features in the connector.
You need to execute these methods against the Configuration object before passing it to the Connector's constructor. For example:
```php
$configuration = new \Akeeba\Engine\Postproc\Connector\S3v4\Configuration(
'YourAmazonAccessKey',
'YourAmazonSecretKey'
);
// Use v4 signatures and Dualstack URLs
$configuration->setSignatureMethod('v4');
$configuration->setUseDualstackUrl(true);
$connector = new \Akeeba\Engine\Postproc\Connector\S3v4\Connector($configuration);
```
### HTTPS vs plain HTTP
**It is not recommended to use plain HTTP connections to Amazon S3**. If, however, you have no other option you can tell the Configuration object to use plain HTTP URLs:
```php
$configuration->setSSL(false);
```
### Custom endpoint
You can use the Akeeba Amazon S3 Connector library with S3-compatible APIs such as DigitalOcean's Spaces by changing the endpoint URL.
Please note that if the S3-compatible APi uses v4 signatures you need to enter the region-specific endpoint domain name and the region when initializing the object, e.g.:
```php
// DigitalOcean Spaces using v4 signatures
// The access credentials are those used in the example at https://developers.digitalocean.com/documentation/spaces/
$configuration = new \Akeeba\Engine\Postproc\Connector\S3v4\Configuration(
'532SZONTQ6ALKBCU94OU',
'zCkY83KVDXD8u83RouEYPKEm/dhPSPB45XsfnWj8fxQ',
'v4',
'nyc3'
);
$configuration->setEndpoint('nyc3.digitaloceanspaces.com');
$connector = new \Akeeba\Engine\Postproc\Connector\S3v4\Connector($configuration);
```
If your S3-compatible API uses v2 signatures you do not need to specify a region.
```php
// DigitalOcean Spaces using v2 signatures
// The access credentials are those used in the example at https://developers.digitalocean.com/documentation/spaces/
$configuration = new \Akeeba\Engine\Postproc\Connector\S3v4\Configuration(
'532SZONTQ6ALKBCU94OU',
'zCkY83KVDXD8u83RouEYPKEm/dhPSPB45XsfnWj8fxQ',
'v2'
);
$configuration->setEndpoint('nyc3.digitaloceanspaces.com');
$connector = new \Akeeba\Engine\Postproc\Connector\S3v4\Connector($configuration);
```
### Legacy path-style access
The S3 API calls made by this library will use by default the subdomain-style access. That is to say, the endpoint will be prefixed with the name of the bucket. For example, a bucket called `example` in the `eu-west-1` region will be accessed using the endpoint URL `example.s3.eu-west-1.amazonaws.com`.
If you have buckets with characters that are invalid in the context of DNS (most notably dots and uppercase characters) this will fail. You will need to use the legacy path style instead. In this case the endpoint used is the generic region specific one (`s3.eu-west-1.amazonaws.com` in our example above) and the API URL will be prefixed with the bucket name.
You need to do:
```php
$configuration->setUseLegacyPathStyle(true);
```
Caveat: this will not work with v2 signatures if you are using Amazon AWS S3 proper. It will work with the v2 signatures if you are using a custom endpoint, though. In fact, most S3-compatible APIs implementing V2 signatures _expect_ you to use path-style access.
### Dualstack (IPv4 and IPv6) support
Amazon S3 supports dual-stack URLs which resolve to both IPv4 and IPv6 addresses. By default they are _not_ used. If you want to enable this feature you need to do:
```php
$connector->setUseDualstackUrl(true);
```
Caveat: this option only takes effect if you are using Amazon S3 proper. It will _not_ have any effect with custom endpoints.

Need to check:
endpoint in [amazon, custom]
signature in [v2, v4]
path style in [true, false]
upload
download
presigned URL generation
presigned URL access
USING VIRTUAL HOSTING, v4 SIGNATURES
presigned URL must use s3.amazonaws.com i.e. path-style hosting (because who needs logic?)

* - Write-only, bucket-restricted keys

* !!!! DO NOT TOUCH THIS CODE. YOU WILL BREAK PRE-SIGNED URLS WITH v4 SIGNATURES. !!!!
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* The following two lines seem weird and possibly extraneous at first glance. However, they are VERY important.
* If you remove them pre-signed URLs for v4 signatures will break! That's because pre-signed URLs with v4
* signatures follow different rules than with v2 signatures.
*
* Authenticated (pre-signed) URLs are always made against the generic S3 region endpoint, not the bucket's
* virtual-hosting-style domain name. The bucket is always the first component of the path.
*
* For example, given a bucket called foobar and an object baz.txt in it we are pre-signing the URL
* https://s3-eu-west-1.amazonaws.com/foobar/baz.txt, not
* https://foobar.s3-eu-west-1.amazonaws.com/foobar/baz.txt (as we'd be doing with v2 signatures).
*
* The problem is that the Request object needs to be created before we can convey the intent (regular request
* or generation of a pre-signed URL). As a result its constructor creates the (immutable) request URI solely
* based on whether the Configuration object's getUseLegacyPathStyle() returns false or not.
*
* Since we want to request URI to contain the bucket name we need to tell the Request object's constructor that
* we are creating a Request object for path-style access, i.e. the useLegacyPathStyle flag in the Configuration
* object is true. Naturally, the default behavior being virtual-hosting-style access to buckets, this flag is
* most likely **false**.
*
* Therefore we need to clone the Configuration object, set the flag to true and create a Request object using
* the falsified Configuration object.
*
* Note that v2 signatures are not affected. In v2 we are always appending the bucket name to the path, despite
* the fact that we include the bucket name in the domain name.
*
