基本 AWS S3 PHP 设置

Question

我已经尝试了一段时间来设置一个基本的 PHP 上传表单实现以上传到 Amazon 的 S3 服务，但我什么都做不了。

通读他们的文档，他们的例子似乎都不一样。 提供凭据和上传文件的正确方法是什么？

在他们的 github 回购协议中，它说：

// Require the Composer autoloader.
require 'vendor/autoload.php';

use Aws\S3\S3Client;

// Instantiate an Amazon S3 client.
$s3 = new S3Client([
    'version' => 'latest',
    'region'  => 'us-west-2'
]);

try {
    $s3->putObject([
        'Bucket' => 'my-bucket',
        'Key'    => 'my-object',
        'Body'   => fopen('/path/to/file', 'r'),
        'ACL'    => 'public-read',
    ]);
} catch (Aws\Exception\S3Exception $e) {
    echo "There was an error uploading the file.\n";
}

在 http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html 他们说：

use Aws\S3\S3Client;

$client = S3Client::factory(array(
    'profile' => '<profile in your aws credentials file>'
));

// Upload an object by streaming the contents of a file
// $pathToFile should be absolute path to a file on disk
$result = $client->putObject(array(
    'Bucket'     => $bucket,
    'Key'        => 'data_from_file.txt',
    'SourceFile' => $pathToFile,
    'Metadata'   => array(
        'Foo' => 'abc',
        'Baz' => '123'
    )
));

// We can poll the object until it is accessible
$client->waitUntil('ObjectExists', array(
    'Bucket' => $this->bucket,
    'Key'    => 'data_from_file.txt'
));

最近能够做到这一点的任何人都可以阐明这里的设置吗？

Answer 1

您链接到的文档中的关键是这句话：

您可以像前面的示例一样提供您的凭据配置文件，直接指定您的访问密钥（通过密钥和秘密），或者 您可以如果您使用的是 AWS，请选择省略任何凭证信息 EC2 实例的身份和访问管理 (IAM) 角色

因此，如果您运行来自 EC2 实例，您只需省略任何凭证，它应该从与实例关联的角色中获取权限。

如果您不在 AWS 中运行，则需要为用户运行创建 ~/.aws/config 代码，并创建一个类似于

[profile profile_name]
aws_access_key_id = key
aws_secret_access_key = secret
region = us-east-1

那么你只需要做：

$client = S3Client::factory(array(
  'profile' => 'profile_name'
));

Answer 2

我最终仅通过使用嵌入式凭据就让它工作了

<?php

date_default_timezone_set("America/Denver");

require "./aws/aws-autoloader.php";

use Aws\S3\S3Client;

$s3Client = S3Client::factory(array(
    'credentials' => array(
        'key'    => 'key',
        'secret' => 'secret',
    ),
    "region" => "us-east-1",
    "version" => "latest"
));

安装作曲家安装 PHP CLI 后，使用以下命令下载 Composer 安装程序脚本：

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

使用 PHP 版本

编译 Composer

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

检查作曲家 composer

Install/download aws sdk 库

composer require aws/aws-sdk-php

php -d memory_limit=-1 composer.phar require aws/aws-sdk-php
