How to use AWS SDK for PHP with Minio Server

aws-sdk-php is the official AWS SDK for the PHP programming language. In this recipe we will learn how to use aws-sdk-php with Minio server.

1. Prerequisites

Install Minio Server from here.

2. Installation

Install aws-sdk-php from AWS SDK for PHP official docs here.

3. Use GetObject and PutObject

Example below shows putObject and getObject operations on Minio server using aws-sdk-php. Please replace endpoint,key, secret, Bucket with your local setup in this example.php file. Note that we set use_path_style_endpoint to true to use Minio with AWS SDK for PHP. Read more in the AWS SDK for PHP docs here.

Copy<?php
// Include the SDK using the Composer autoloader
date_default_timezone_set('America/Los_Angeles');
require 'vendor/autoload.php';
$s3 = new Aws\S3\S3Client([
        'version' => 'latest',
        'region'  => 'us-east-1',
        'endpoint' => 'http://localhost:9000',
        'use_path_style_endpoint' => true,
        'credentials' => [
                'key'    => 'YOUR-ACCESSKEYID',
                'secret' => 'YOUR-SECRETACCESSKEY',
            ],
]);
// Send a PutObject request and get the result object.
$insert = $s3->putObject([
     'Bucket' => 'testbucket',
     'Key'    => 'testkey',
     'Body'   => 'Hello from Minio!!'
]);
// Download the contents of the object.
$retrive = $s3->getObject([
     'Bucket' => 'testbucket',
     'Key'    => 'testkey',
     'SaveAs' => 'testkey_local'
]);
// Print the body of the result by indexing into the result object.
echo $retrive['Body'];

After the file is updated, run the program

Copyphp example.php
Hello from Minio!!

4. Create a pre-signed URL

Copy<?php
// Get a command object from the client
$command = $s3->getCommand('GetObject', [
            'Bucket' => 'testbucket',
            'Key'    => 'testkey'
        ]);
// Create a pre-signed URL for a request with duration of 10 miniutes
$presignedRequest = $s3->createPresignedRequest($command, '+10 minutes');
// Get the actual presigned-url
$presignedUrl =  (string)  $presignedRequest->getUri();

5. Get a plain URL

To get a plain URL, you'll need to make your object/bucket accessible with public permission. Also, note that you'll not get the URL with X-Amz-Algorithm=[...]&X-Amz-Credential=[...]&X-Amz-Date=[...]&X-Amz-Expires=[...]&X-Amz-SignedHeaders=[...]&X-Amz-Signature=[...]

Copy<?php
$plainUrl = $s3->getObjectUrl('testbucket', 'testkey');

6. Set a Bucket Policy

Copy<?php
$bucket = 'testbucket';
// This policy sets the bucket to read only
$policyReadOnly = '{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "s3:GetBucketLocation",
        "s3:ListBucket"
      ],
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "*"
        ]
      },
      "Resource": [
        "arn:aws:s3:::%s"
      ],
      "Sid": ""
    },
    {
      "Action": [
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "*"
        ]
      },
      "Resource": [
        "arn:aws:s3:::%s/*"
      ],
      "Sid": ""
    }
  ]
}
';
// If you want to put it on a specific folder you just change 'arn:aws:s3:::%s/*' to 'arn:aws:s3:::%s/folder/*'
// Create a bucket
$result = $s3->createBucket([
    'Bucket' => $bucket,
]);
// Configure the policy
$s3->putBucketPolicy([
    'Bucket' => $bucket,
    'Policy' => sprintf($policyReadOnly, $bucket, $bucket),
]);
获取对象的方法：
            $result = $client->getObject(array(
                'Bucket'                     => '123124',
                'Key'                        => '2018022610202562513.jpeg',
                'ResponseContentType'        => 'image/jpeg',
                // 'ResponseContentLanguage'    => 'en-US',
                // 'ResponseContentDisposition' => 'attachment; filename=testing.txt',
                // 'ResponseCacheControl'       => 'No-cache',
                // 'ResponseExpires'            => gmdate(DATE_RFC2822, time() + 3600),
            ));
