Laravel Minio Temporary URL

Question

I'm looking for a hacky way to create temporary URLs with Minio

I see on the Laravel docs it says: Generating temporary storage URLs via the temporaryUrl method is not supported when using MinIO.

However from some digging I noticed that I can upload images successfully using:

AWS_ENDPOINT=http://minio:9000

I can't view them because the temporary url is on http://minio:9000/xxx

If I change the AWS endpoint to

AWS_ENDPOINT=http://localhost:9000

The temporary url is on http://localhost:9000/xxx, the signature is validated and the file can be viewed.

The issue exists in this call to make the command. The $command needs to have the host changed but I don't know if I can do that by just passing in an option.

        $command = $this->client->getCommand('GetObject', array_merge([
            'Bucket' => $this->config['bucket'],
            'Key' => $this->prefixer->prefixPath($path),
        ], $options));

There is also the option to just change the baseUrl by providing a temporary_url in the filesystem config. however, because the URL has changed the signature is invalid.

Is there a way I can update the S3Client to use a different host either by passing an option to the getCommand function or by passing a new S3Client to the AWS adapter to use the correct host?

Do you get the solution? I am facing the same problem.

If you want to generate temporary URLs with Minio in Laravel, there is a way to do it by extending the default Aws\S3\S3Client class and modifying its createPresignedRequest() method.

Here's an example implementation that you can use:

use Aws\S3\S3Client;

class MinioClient extends S3Client
{
    public function createPresignedRequest($command, $expires, array $options = [])
    {
        $url = parent::createPresignedRequest($command, $expires, $options)->getUri();
        $url = str_replace('http://localhost:9000', 'http://minio:9000', $url);
        return new Psr7\Request($command->getName(), $url);
    }
}

This implementation extends the Aws\S3\S3Client class and overrides the createPresignedRequest() method. Within the method, it first calls the parent createPresignedRequest() method to generate the temporary URL with the default options. Then, it modifies the generated URL by replacing the http://localhost:9000 with http://minio:9000. Finally, it creates a new Psr7\Request object with the modified URL and returns it.

You can then use this MinioClient class to generate temporary URLs as follows:

use Illuminate\Support\Facades\Storage;

// Get an instance of the Minio client
$client = new MinioClient([
    'version' => 'latest',
    'region' => 'us-east-1',
    'endpoint' => env('MINIO_ENDPOINT'),
    'use_path_style_endpoint' => true,
    'credentials' => [
        'key' => env('MINIO_ACCESS_KEY'),
        'secret' => env('MINIO_SECRET_KEY'),
    ],
]);

// Set the expiration time for the temporary URL (in seconds)
$expires = 60; // 1 minute

// Generate the temporary URL for the object
$objectUrl = 'my-object.txt';
$temporaryUrl = $client->getObjectUrl(env('MINIO_BUCKET'), $objectUrl, "+$expires seconds");

In this example, we first create an instance of the MinioClient class by passing the required configuration options. We then set the expiration time for the temporary URL (in this case, 1 minute), and generate the temporary URL for the object named my-object.txt in the MINIO_BUCKET bucket.

Note that this implementation is a hacky workaround and may have potential security issues. It is recommended to use the official Minio client library or find a more secure solution if possible.
