我已经尝试了一段时间来设置上传表单的基本PHP实现，以上传到亚马逊的S3服务，但我什么都做不到。
通过阅读他们的文档，他们的例子似乎都不一样提供凭据和上传文件的正确方式是什么
在他们的github回购上，上面写着：
// 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";
}
Onhttp://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人能对这里的设置有所了解吗？
您链接到的文档中的密钥是这样一句话：
您可以像前面的示例一样提供凭据配置文件，直接指定您的访问密钥（通过密钥和密钥），或者您可以如果您正在使用AWS，请选择省略任何凭据信息EC2实例的身份和访问管理（IAM）角色
因此，如果您从EC2实例运行此操作，只需省略任何凭据的提及，它应该从与实例关联的角色中获取权限。
如果你没有在AWS中运行，你需要为运行代码的用户创建~/.AWS/config，并创建一个看起来像的配置文件
[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'
));
我最终通过使用嵌入的凭据使其工作
<?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Composer安装PHP CLI后，下载Composer安装程序脚本，其中包含：
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
用PHP版本编译Composer
sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
检查composercomposer
安装/下载aws-sdk库
composer require aws/aws-sdk-php
php -d memory_limit=-1 composer.phar require aws/aws-sdk-php
示例代码下载文件
<?php
require 'vendor/autoload.php';
use Aws'S3'S3Client;
$bucket ="sentimentanalysis2021";
$key ="KEY";
$secret ="SecretKEY";
$region ="ap-south-1";
$location = "/var/www/html/openpbx/record/temp/";
// Establish connection with DreamObjects with an S3 client.
$client = new Aws'S3'S3Client([
'version' => '2006-03-01',
'region' => $region,
'endpoint' => "https://s3.$region.amazonaws.com/",
'credentials' => [
'key' => $key,
'secret' => $secret,
]
]);
//var_dump($client);
//Download File
$file_s3 = null;
$objects = $client->getPaginator('ListObjects', ['Bucket' => $bucket]);
foreach ($objects as $listResponse) {
$items = $listResponse->search("Contents[?ends_with(Key,'wav')]");
foreach($items as $item) {
// download($client,$item['Key'],$location);
$client->getObject(array(
'Bucket' => $bucket,
'Key' => $item['Key'],
'SaveAs' => $location.$item['Key']
));
$file_s3 =$location.$item['Key'];
}
}
//Read Files
$objects = $client->listObjectsV2([
'Bucket' => $bucket,
]);
foreach ($objects['Contents'] as $object){
echo "{$object['Key']}'t{$object['LastModified']}'n";
}
function download($client,$file,$location){
$client->getObject(array(
'Bucket' => $bucket,
'Key' => $file,
'SaveAs' => $location.$file
));
}
// Create Folder
/* abc is the folder name */
$client->putObject(array(

'Body' => "",
'ACL' => 'public-read'

$file_Path = '/amol/20220516141901_919033_9999.wav';

try{
$result = $client->putObject([
