rewind() expects parameter 1 to be resource, string given

AliOssAdapter : 428

    /**
     * {@inheritdoc}
     */
    public function readStream($path)
    {
        $result = $this->readObject($path);
        $result['stream'] = $result['raw_contents'];
        rewind($result['stream']);
        // Ensure the EntityBody object destruction doesn't close the stream
        $result['raw_contents']->detachStream();
        unset($result['raw_contents']);

        return $result;
    }

其中 raw_contents 是 string

你是如何出现这个错误的，请提供一下重现方法或者你是使用哪个接口导致这个错误的，我这边测试暂时没有报这个错误

This is my code

    public function render($file, $path, $width = 350, $height = 350) {
        if ($file == null) {
            return null;
        }

        $server = \League\Glide\ServerFactory::create([
            'cache' => Storage::disk('oss')
                              ->getDriver(),
            'cache_path_prefix' => $path . '/cache/',
            'source' => Storage::disk('oss')
                               ->getDriver(),
            'source_path_prefix' => $path,
            'response' => new SymfonyResponseFactory(),
            'defaults' => [
                'q' => 80,
            ]
        ]);

        // Set API
        $api = new \League\Glide\Api\Api(new \Intervention\Image\ImageManager([
            'driver' => self::DRIVER,
        ]), [
            //                new \League\Glide\Manipulators\Orientation(),
            new \League\Glide\Manipulators\Crop(),
            new \League\Glide\Manipulators\Size(2000 * 2000),
            new \League\Glide\Manipulators\Brightness(),
            new \League\Glide\Manipulators\Contrast(),
            new \League\Glide\Manipulators\Gamma(),
            new \League\Glide\Manipulators\Sharpen(),
            new \League\Glide\Manipulators\Filter(),
            new \League\Glide\Manipulators\Blur(),
            new \League\Glide\Manipulators\Pixelate(),
            new \League\Glide\Manipulators\Background(),
            new \League\Glide\Manipulators\Border(),
            new \League\Glide\Manipulators\Encode(),
        ]);

        $server->setApi($api);

        try {
            return $server->getImageResponse($file, ["w" => $width, "h" => $height]);

        } catch (\Exception $e) {
            LogManager::e($e);
        }

        return null;

    }

and this is an error i am getting

ErrorException: rewind() expects parameter 1 to be resource, string given in ...\vendor\jacobcyl\ali-oss-storage\src\AliOssAdapter.php:453

@jacobcyl
I composer your jacobcyl/ali-oss-storage 2.1 package， call the following mehtod in laravel 5.5.
return Storage::download(
$export->file_path,
$export->start_day->format('Ymd').'-'.$export->end_day->format('Ymd').'.xlsx'
);

I dig into the code in jacobcyl/ali-oss-storage/src/AliOssAdapter.php, found the "$result['raw_contents']" is a string, not resource.

public function readStream($path)
{
$result = $this->readObject($path);
$result['stream'] = $result['raw_contents'];
rewind($result['stream']);
// Ensure the EntityBody object destruction doesn't close the stream
$result['raw_contents']->detachStream();
unset($result['raw_contents']);

    return $result;
}

hi, xakzona. how did you fix this bug? I fix the Jacobcyl\AliOSS\AliOssAdapter::readStream() as below
public function readStream($path)
{
$result = $this->readObject($path);
$result['stream'] = fopen($this->getUrl($path), 'r');
// $result['stream'] = $result['raw_contents'];
// rewind($result['stream']);
// Ensure the EntityBody object destruction doesn't close the stream
// $result['raw_contents']->detachStream();
unset($result['raw_contents']);

    return $result;
}

This pull request is not mine, you can read solution here but it in merging state

[fengliang2011]

the solution still has a bug on line 455, php resource is not object, so it has no member mehtod detachStream().

Have you seen my own merge request about this problem?

I have checked it by condition
is_resource($result['raw_contents'])
before rewind
