创建亚马逊 aws s3 预签名 url PHP

Question

根据这个 link http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html，我可以轻松地创建一个预签名 link 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=[...]

但是我得到一个普通的 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，如果其他人像我一样有任何问题，这就是答案，我进入了亚马逊 php 开发论坛并得到了专业人士的帮助。

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.Install 作曲家，最好使用 sudo:

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

2.Go 到你的项目文件夹并创建一个 composer.json 文件，你的版本是 want/need，你可以在这里找到发布：https://github.com/aws/aws-sdk-php/releases，每个版本的命令似乎是非常特定于版本的，要小心，这是我的主要问题。

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

}

3.Then 进入终端中的项目文件夹，通过 composer 安装 sdk，然后像这样更新：（如果更改版本，则必须再次更新。）

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

4.Then 一切都准备就绪，您可以按照正确的版本文档进行操作，在我的情况下，版本 "aws/aws-sdk-php"：“~3.0” 和预签名 url，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;

我希望这对遇到与我相同问题的人有所帮助。

Answer 2

如果您使用的是 Laravel，您可以轻松获得 S3 的临时 URL，如此处记录：https://laravel.com/docs/master/filesystem#file-urls

您的 Image 模型示例为：

class Image extends Model
{

    ...

    public function getTemporaryUrlAttribute()
    {
        return Storage::disk('s3')->temporaryUrl(
            $this->path,
            now()->addSeconds(10)
        );
    }
}

那么在您的 HTML 中它将是：

<img width="100px" src="{{$image->temporaryUrl}}">
