How can I download file from s3 in php?

本文关键字：文件 php 下载 s3 | 更新日期: 2023-09-27

如何在php中从s3下载文件?下面的代码不为我工作…这是我的代码

上传文件应该能正常工作

    try {
    $s3->putObject([
        'Bucket' => $config['s3']['bucket'],//'eliuserfiles',
        'Key'    => "uploads/{$name}",
        'Body'   =>  fopen($tmp_name, 'r+'),
        //'SourceFile' => $pathToFile,
        'ACL'    => 'public-read',
    ]);

download gives me error

  $objInfo = $s3->get_object_headers($config['s3']['bucket'], "uploads/{$name}");
    $obj = $s3->get_object($config['s3']['bucket'], "uploads/{$name}");
    header('Content-type: ' . $objInfo->header['_info']['content_type']);
    echo $obj->body;

误差

 PHP Catchable fatal error:  Argument 2 passed to Aws''AwsClient::getCommand() must be of the type array, string given, called in /php_workspace/s3_php/vendor/aws/aws-sdk-php/src/AwsClient.php on line 167 and defined in /php_workspace/s3_php/vendor/aws/aws-sdk-php/src/AwsClient.php on line 211, referer: http://localhost/upload.php

简单的方法:

包括Amazon S3 PHP Class在你的项目。

实例化类:

1。OO方法(e,g;s3 -> getObject(…)):

$s3 = new S3($awsAccessKey, $awsSecretKey);

2。静态(e, g;S3: getObject(…)):

S3::setAuth($awsAccessKey, $awsSecretKey);

// Return an entire object buffer:
    $object = S3::getObject($bucket, $uri));
    var_dump($object);

通常，最有效的方法是将对象保存到文件或资源

<?php
    // To save it to a file (unbuffered write stream):
    if (($object = S3::getObject($bucket, $uri, "/tmp/savefile.txt")) !== false) {
        print_r($object);
    }
    // To write it to a resource (unbuffered write stream):
    $fp = fopen("/tmp/savefile.txt", "wb");
    if (($object = S3::getObject($bucket, $uri, $fp)) !== false) {
        print_r($object);
    }
?>

S3 Class -With example

S3类-文档

你可以试试:

$bucket= "bucket-name";
$filetodownload = "name-of-the-file";
$resultbool = $s3->doesObjectExist ($bucket, $filetodownload );
if ($resultbool) {
    $result = $client->getObject ( [ 
    'Bucket' => $bucket,
    'Key' => $filetodownload 
] );
}
else
{
    echo "file not found";die;
}
header ( "Content-Type: {$result['ContentType']}" );
header ( "Content-Disposition: attachment; filename=" . $filetodownload );
header ('Pragma: public');
echo $result ['Body'];
die ();
