创建Amazon AWS S3预签名URL PHP [英] Creating amazon aws s3 pre signed url PHP

问题描述

根据此链接 http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html ，我可以轻松地创建一个预签名链接，只需将寿命添加到getObjectUrl

According to this link http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html, I can easily create a presigned link just adding the life span to getObjectUrl

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

但是，我得到一个简单的网址，没有awsaccesskeyid和expires参数，

But I get a plain url, you know, without the awsaccesskeyid and expires parameters,

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>";

我将AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY作为环境变量

我的回声如下:

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

怎么了?

推荐答案

好吧，如果有人像我那样遇到任何麻烦，这就是答案，我进入了amazon php开发论坛并获得了专业人士的帮助

Well, if anyone else has any trouble with this like I did, here is the answer, I went into the amazon php development forums and got help from the profesionals.

似乎您可能在SDK的版本2和版本3之间切换，或者查看了错误的文档.确保您准备好要使用的产品，并正在查看正确的文档.他们是不同的.

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.

有关您必须做什么的小型分步指南:

Mini step-by-step guide of what you have to do:

1.安装作曲家，最好使用sudo:

1.Install composer, preferably using 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，您可以在此处找到发行版:

2.Go to your project folder and create a composer.json file, with the version you want/need, you can find releases here: https://github.com/aws/aws-sdk-php/releases, commands for each version seem to be very version specific, be careful, this was my main problem.

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

}

3.然后转到终端中的项目文件夹，并通过composer安装sdk并随后进行更新，例如:(如果更改版本，则必须再次更新.)

3.Then go to your project folder in the terminal, and install sdk via composer and update afterward like: (if you change version you have to update again.)

    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，在我的情况下，版本为"aws/aws-sdk-php":〜3.0"，而对于预签名的url，有效的方法是:

4.Then everything is ready for you to follow proper version documentation, in my case for version "aws/aws-sdk-php": "~3.0" and for presigned url, what worked was:

    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遇到与我相同的问题的人.

I hope this helps anyone facing the same problems as I did.
