php - 创建 amazon aws s3 预签名 url PHP

Question

根据此链接http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html ，我可以轻松创建一个预签名链接，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=[...]

但是我得到了一个简单的 url，你知道，没有 awsaccesskeyid 和过期参数，

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 echo 看起来像:

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

出了什么问题？

好吧，如果其他人像我一样遇到任何问题，这就是答案，我进入了亚马逊 php 开发论坛并从专业人士那里获得了帮助。

It seems you may be flip-flopping between Version 2 and Version 3 of the SDK or looking at the wrong document. Make sure you are getting the one you intend to use and are looking at the correct documentation. They are different.

V3 - Composer Requirement: {"aws/aws-sdk-php": "~3.0"} - User Guide: http://docs.aws.amazon.com/aws-sdk-php/v3/guide/index.html - API Docs: http://docs.aws.amazon.com/aws-sdk-php/v3/api/index.html - Pre-signed URL Docs: http://docs.aws.amazon.com/aws-sdk-php/v3/guide/service/s3-presigned-url.html

V2 - Composer Requirement: {"aws/aws-sdk-php": "~2.8"} - User Guide: http://docs.aws.amazon.com/aws-sdk-php/v2/guide/index.html - API Docs: http://docs.aws.amazon.com/aws-sdk-php/v2/api/index.html - Pre-signed URL Docs: http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html#creating-a-pre-signed-url

关于您必须做什么的迷你分步指南:

1.安装composer，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创建一个composer.json文件，其中包含您想要/需要的版本，您可以在此处找到版本:https://github.com/aws/aws-sdk-php/releases ，每个版本的命令似乎都非常特定于版本，小心，这是我的主要问题。

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

}

3.然后进入终端中的项目文件夹，通过composer安装sdk并随后更新，如下所示:(如果更改版本，则必须再次更新。)

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

4.然后一切准备就绪，您可以遵循正确的版本文档，在我的例子中，版本“aws/aws-sdk-php”:“~3.0”和预签名网址，有效的是:

    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;

我希望这可以帮助任何面临与我相同问题的人。
