创建amazon aws s3预签名网址PHP

Question

根据这个链接http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html,我可以轻松地创建一个预先指定的链接,只需将生命周期添加到getObjectUrl

$signedUrl = $client->getObjectUrl($bucket, 'data.txt', '+10 minutes');
// > https://my-bucket.s3.amazonaws.com/data.txt?AWSAccessKeyId=[...]&Expires=[...]&Signature=[...]

但是我得到一个简单的URL,你知道,没有awsaccesskeyid和expires参数,

这是我的代码:

$bucket = 'imagenesfc';
$keyname = 'NASimagenes/codigoBarraBoleto/1001000098.png';
$filepath = 'NASimagenes/codigoBarraBoleto';

// Instantiate the client.
$s3 = S3Client::factory(array(
    'version' => 'latest',
    'region' => 'us-west-1'
));
 $signedUrl = $s3->getObjectUrl($bucket, $keyname,'+10 minutes');
// > https://my-bucket.s3.amazonaws.com/data.txt?AWSAccessKeyId=[...]&Expires=[...]&Signature=[...]
 echo $signedUrl."<br>";

编辑:我有AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY作为环境变量

我的回声看起来像:

https://s3-us-west-1.amazonaws.com/imagenesfc/NASimagenes/codigoBarraBoleto/1001000098.png

怎么了？

好吧,如果有其他人像我一样有任何麻烦,这里是答案,我进入亚马逊php开发论坛,并得到专业人士的帮助.

看起来你可能在SDK的版本2和版本3之间翻转或查看错误的文档.确保您获得了打算使用的那个,并且正在查看正确的文档.它们是不同的.

V3 - 作曲家要求:{"aws/aws-sdk-php":"~3.0"} - 用户指南:http://docs.aws.amazon.com/aws-sdk-php/v3/guide/index.html - API文档:http://docs.aws.amazon.com/aws-sdk-php/v3/api/index.html - 预先签名的URL文档:http://docs.aws.amazon.com/aws- SDK-PHP/V3 /引导/服务/ S3-presigned-url.html

V2 - 作曲家要求:{"aws/aws-sdk-php":"~2.8"} - 用户指南:http://docs.aws.amazon.com/aws-sdk-php/v2/guide/index.html - API文档:http://docs.aws.amazon.com/aws-sdk-php/v2/api/index.html - 预先签名的URL文档:http://docs.aws.amazon.com/aws- SDK-PHP/V2 /引导/服务s3.html#创建-A-前签署的URL

您需要做的迷你分步指南:

1.安装作曲家,最好使用sudo:

    sudo curl -sS https://getcomposer.org/installer | sudo php

2.转到您的项目文件夹并使用您想要/需要的版本创建一个composer.json文件,您可以在此处找到版本:https://github.com/aws/aws-sdk-php/releases,每个命令版本似乎非常具体版本,小心,这是我的主要问题.

{
    "require": {
        "aws/aws-sdk-php": "~3.0"
    }

}

3.然后转到终端中的项目文件夹,然后通过composer安装sdk并在之后更新,如:(如果你更改了版本,你必须再次更新.)

    sudo php composer.phar install
    sudo php composer.phar update

4.然后一切都准备就绪,你可以按照正确的版本文档,在我的情况下,对于版本"aws/aws-sdk-php":"~3.0"和预先签名的url,有用的是:

    require 'vendor/autoload.php';
    use Aws\S3\S3Client;
    use Aws\S3\Exception\S3Exception;

    $sharedConfig = [
        'region'  => 'us-west-1',
        'version' => 'latest'
    ]; //I have AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY as environment variables

    $s3Client = new Aws\S3\S3Client($sharedConfig);

    $cmd = $s3Client->getCommand('GetObject', [
        'Bucket' => $bucket,
        'Key'    => $keyname
    ]);

    $request = $s3Client->createPresignedRequest($cmd, '+20 minutes');
    $presignedUrl = (string) $request->getUri();
    echo $presignedUrl;

我希望这能帮助任何面临同样问题的人.
