stream_context_set_params不适用于ssh2.sftp包装器 [英] stream_context_set_params not works with ssh2.sftp wrapper
问题描述
我想使用此处之类的功能.请检查下面的代码
I want to use functionality like here. Please check the code bellow
function notify (
$notification_code,
$severity,
$message,
$message_code,
$bytes_transferred,
$bytes_max
) {
echo "Runned \n";
};
$ctx = stream_context_create();
stream_set_params($ctx, array('notification' => 'notify'));
$ssh_connection = ssh2_connect('myhost');
ssh2_auth_password($ssh_connection, 'login','pass');
$sftp_resource = ssh2_sftp($ssh_connection);
$data = file_get_contents("ssh2.sftp://{$sftp_resource}/path/to/big/file",
false, $ctx);
我希望我的notify函数将至少被调用一次. 实际上,相同的代码适用于ftp包装器
I expect that my notify function will be called at least once. Actually, the same code works for ftp wrappers
function notify (
$notification_code,
$severity,
$message,
$message_code,
$bytes_transferred,
$bytes_max
) {
echo "Runned \n";
};
$ctx = stream_context_create();
stream_set_params($ctx, array('notification' => 'notify'));
$scheme = 'ftp';
$data = file_get_contents("{scheme}://username:password@host:port/path/to/file",
false, $ctx);
工作正常! notify函数被多次调用. 我尝试像这样使用sftp包装器
And it works fine! The notify function is called many times. I try to use sftp wrapper like this
$data = file_get_contents("ssh2.sftp://username:password@host:port/path/to/big/file",
false, $ctx);
它也不起作用. 有什么想法吗?
And it isn`t works too. Any ideas?
推荐答案
ssh2扩展名不支持通知回调.我不知道这是设计使然还是未实现,但是扩展代码缺少对以下函数的调用:
The ssh2 extension doesn't support notfication callbacks. I don't know if this is by design or just not implemented, but the extensions code is missing calls to functions like:
来自(PHP-5.4.10)/ext/standard/ftp_fopen_wrapper.c,第573行:
From (PHP-5.4.10) /ext/standard/ftp_fopen_wrapper.c, line 573:
php_stream_notify_progress_init(context, 0, file_size);
一种解决方法,我尚未测试过,可能是使用ftps://
(基于SSL的FTP).它应该符合您的安全需求,并且-如代码所示-将支持ftp等通知.详细地说,它使用与ftp相同的urlwrapper.
A workaround, which I've not tested yet might be to use ftps://
(FTP over ssl). It should fit your security needs and - as the code looks like - will support notifications as ftp. In detail, it uses the same urlwrapper as ftp.
