只有14个字节上载到Google Cloud Storage

Question

I'm trying to upload some files into Google Cloud Storage using PHP. It seems to be partially working, since I'm seeing the files in the web console, however I've noticed that all files are only 14 bytes in size, while the original is much bigger.

This is the code I'm using:

/**
 *
 */
public static function saveFile($originalFile, $newFilename) {

    $bucket = MyStorage::getBucket();

    if ($bucket == null) {

        // Save locally
        Storage::disk('local')->put(FileController::$FILE_DIR . $newFilename, file_get_contents($originalFile));

    } else {

        // Save to Google Cloud Platform
        $bucket->upload($originalFile->getRealPath(), ['name' => $newFilename]);

    }
}

/**
 *
 */
private static function getBucket() {

    $appEnv = getenv('APP_ENV');

    if ($appEnv == "production" || $appEnv == "test") {

        $GOOGLE_CLOUD_PROJECT_ID = getenv('GOOGLE_PROJECT_ID');
        $GOOGLE_CLOUD_BUCKET_NAME = getenv('GOOGLE_BUCKET_NAME');

        $storage = new StorageClient(['projectId' => $GOOGLE_CLOUD_PROJECT_ID]);
        $bucket = $storage->bucket($GOOGLE_CLOUD_BUCKET_NAME);

        return $bucket;

    } else {

        return null;
    }
}

$originalFile->getRealPath() returns something like /tmp/asdfasdfadf and I've verified that that file exists and is a reasonable size. The $newFilename variable name is what I want it to be stored as and this part seems to work as I'm seeing that filename in the web console.

Any ideas what could be happening?

Answer 1

It seems you're only uploading the path to the file as a string, as opposed to the actual file.

If you look at the client library, they seem to use fopen

$bucket->upload( fopen($originalFile->getRealPath(), 'rb'), ['name' => $newFilename]);

Answer 2

Yes for using file upload, you need to read the stream of bytes to send it to remote cloud. fopen will do this job for you, to create stream of bytes.

Answer 3

else {

    // Save to Google Cloud Platform
    $bucket->upload($originalFile->getRealPath(), ['name' => $newFilename]);

}

Should be:

else {

    // Save to Google Cloud Platform
    $bucket->upload(fopen($originalFile->getRealPath(), 'rb'), ['name' => $newFilename]);

    if( fclose($originalFile->getRealPath()) === false){
       // Success
    } else{
       // Failure
    }


}

The reason that your code didn't work is because you were uploading only the filename to Google Cloud. "/tmp/asdfasd" is 14 characters.

Here is an answer on why the 'b' is important for the fopen command.

FClose closes the resource, preventing data leaks. Also, check the return value from fclose(), as some OS only flush file output. Checking the return value can save severe data leaks.
