1. 前提条件

从这里下载并安装Minio Server。

2. 安装

从AWS SDK for PHP官方文档下载将安装aws-sdk-php。

3. 使用GetObject和PutObject

下面示例描述的是如何使用aws-sdk-php对Minio Server进行putObject和getObject操作。请将 example.php文件中的endpoint,key, secret, Bucket修改为你的本地配置。注意，我们将use_path_style_endpoint设置为true以使用AWS SDK for PHP来操作Minio。了解更多，请参考AWS SDK for PHP。

<? php
// 使用Composer autoloader引入SDK
date_default_timezone_set ( 'America/Los_Angeles' );
require 'vendor/autoload.php' ;
$s3 = new Aws \S 3 \S 3Client ([
'version' => 'latest' ,
'region' => 'us-east-1' ,
'endpoint' => 'http://localhost:9000' ,
'use_path_style_endpoint' => true ,
'credentials' => [
'key' => 'YOUR-ACCESSKEYID' ,
'secret' => 'YOUR-SECRETACCESSKEY' ,
],
]);
// 发送PutObject请求并获得result对象
$insert = $s3 -> putObject ([
'Bucket' => 'testbucket' ,
'Key' => 'testkey' ,
'Body' => 'Hello from Minio!!'
]);
// 下载文件的内容
$retrive = $s3 -> getObject ([
'Bucket' => 'testbucket' ,
'Key' => 'testkey' ,
'SaveAs' => 'testkey_local'
]);
// 通过索引到结果对象来打印结果的body。
echo $retrive [ 'Body' ];

修改之后，运行程序

php example . php
Hello from Minio !!

4. 生成pre-signed URL

<? php
// 从client中获得一个commad对象
$command = $s3 -> getCommand ( 'GetObject' , [
'Bucket' => 'testbucket' ,
'Key' => 'testkey'
]);
// 获得一个10分钟有效期的pre-signed URL
$presignedRequest = $s3 -> createPresignedRequest ( $command , '+10 minutes' );
// 获得presigned-url
$presignedUrl = ( string ) $presignedRequest -> getUri ();

5. 获取plain URL

获取一个plain URL,你需要将你的object/bucket权限设为public。注意，你不会获得带有后面这些信息的URL， X-Amz-Algorithm=[…]&X-Amz-Credential=[…]&X-Amz-Date=[…]&X-Amz-Expires=[…]&X-Amz-SignedHeaders=[…]&X-Amz-Signature=[…]

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

6. 设置存储桶策略

<? php
$bucket = 'testbucket' ;
// 该策略设置存储桶为只读
$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": ""
 }
 ]
}
' ;
// 如果你想将文件放到指定目录，你只需要修改'arn:aws:s3:::%s/*'为' arn: aws:s3:::%s/folder/*'
// 创建一个存储桶
$result = $s3 -> createBucket ([
'Bucket' => $bucket ,
]);
// 配置策略
$s3 -> putBucketPolicy ([
'Bucket' => $bucket ,
'Policy' => sprintf ( $policyReadOnly , $bucket , $bucket ),
]);
