Problem returning SSH Response

posted 10 years ago

Hello! Thanks for interest to this topic. I'm pretty new in Larave and i have a little question. Maybe it's easy!

I have an SSH module in my Laravel that works this way:

The user fills the textarea element with Linux commands.
The command is passed with Ajax to a method called getExecute() located in the 'controllers' folder

I would like that this method returns me the full response of my SSH server, but this isn't happening. The only thing that the method returns is a blank space. For example: I pass the command 'ls -la', and my response is all folders that the Linux find, like on terminal.

Can someone help me please?

Here is my code:

	public function getExecute()
	{
		if(\Request::ajax()):

			$ssh_command = \Input::get('ssh_command');
			$ssh_response = null;

			return \SSH::run($ssh_command, function($line)
			{
				$line.PHP_EOL;
			});
		
		endif;
	}

OBS: The Ajax connection was tested and it's ok!

Thank you!

            {
                $line.PHP_EOL;
            });

doesn't actually do anything, add a return before it

I've tried to add a return before the command, but the result it's the same thing. Now my command is:

	public function getExecute()
	{
		if(\Request::ajax()):

			$ssh_command = \Input::get('ssh_command');
			$ssh_response = null;

			\SSH::run($ssh_command, function($line)
			{
				return $line.PHP_EOL;
			});
		
		endif;
	}

Solution

Finally solved! Solution below:

First i've created a variable called $output in my class.

private $output;

Then i modified my method to this:

public function postExecute()
{
	$ssh_command = \Input::get('ssh_command');
	$ssh_response = \SSH::run($ssh_command, function($line)
	{
		$this->output = $line.PHP_EOL;
	});

	return $this->output;
}

And it WORKS! Now all that i have to do is rollback to my ajax method like before. Thanks for all!
