使用Filesystem Laravel 5.2从Amazon S3获取文件的签名URL [英] Get file's signed URL from amazon s3 using Filesystem Laravel 5.2

问题描述

我正在寻找一个很好的解决方案，以从Amazon s3获取签名的URL.

I'm looking for a good solution to get the signed url from amazon s3.

我有一个可以使用的版本，但是没有使用laravel:

I have a version working with it, but not using laravel:

private function getUrl ()
{
        $distribution = $_SERVER["AWS_CDN_URL"];

        $cf = Amazon::getCFClient();

        $url = $cf->getSignedUrl(array(
            'url'     => $distribution . self::AWS_PATH.rawurlencode($this->fileName),
            'expires' => time() + (session_cache_expire() * 60)));

        return $url;
}

我不认为这是使用laravel的最佳方法，因为它具有整个文件系统都可以工作...

I don't know if this is the best way to do with laravel, considering it has a entire file system to work...

但是如果没有其他方法，我如何获得客户?调试我已经在Filesystem对象中找到了它的一个实例，但是它是受保护的...

But if don't have another way, how do I get the client? Debugging I've found an instance of it inside the Filesystem object, but it is protected...

推荐答案

在Laravel中，

$s3 = \Storage::disk('s3');
$client = $s3->getDriver()->getAdapter()->getClient();
$expiry = "+10 minutes";

$command = $client->getCommand('GetObject', [
    'Bucket' => \Config::get('filesystems.disks.s3.bucket'),
    'Key'    => "file/in/s3/bucket"
]);

$request = $client->createPresignedRequest($command, $expiry);

return (string) $request->getUri();

确保您也拥有适用于flysystem的AWS for Composer软件包(版本会有所不同):

Make sure you have the AWS for flysystem composer package too (version will vary):

"league/flysystem-aws-s3-v3": "1.0.9"
