Laravel artisan down with message parameter with spaces gives Too many arguments, expected arguments “command”

问题

I run the artisan:

php artisan down --message "Going down for maintenance" --retry=60

[UPDATE] OR run it like @Remul suggested:

php artisan down --message="Going down for maintenance" --retry=60

then both gives me the error:

[Symfony\Component\Console\Exception\RuntimeException]
 Too many arguments, expected arguments "command".

If run command with no spaces like this:

php artisan down --message "Going_down_for_maintenance" --retry=60

No error occurs

I am using php 7.0.14

I figured out:

Problem is actually how php is getting arguments from command line In vendor/symfony/console/Input/ArgvInput.php I could understand that php gets argfuments like this:

0 => "artisan"
  1 => "down"
  2 => "--message=Going"
  3 => "down"
  4 => "for"
  5 => "maintenance"
  6 => "--retry=60"

So to even make sure I made a script of my own with this content:

<?php

var_dump($argv);

And I run it:

php -v;php test_argv.php "parm with space" other_parameter

The output was:

PHP 7.0.14 (cli) (built: Jan 30 2017 15:45:33) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
array(5) {
  [0]=>
  string(13) "test_argv.php"
  [1]=>
  string(4) "parm"
  [2]=>
  string(4) "with"
  [3]=>
  string(5) "space"
  [4]=>
  string(15) "other_parameter"
}

I run it in other machine with a different version of PHP and look at my results:

PHP 7.1.5 (cli) (built: Sep 19 2017 10:48:01) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
    with Xdebug v2.5.4, Copyright (c) 2002-2017, by Derick Rethans
array(3) {
  [0] =>
  string(13) "test_argv.php"
  [1] =>
  string(15) "parm with space"
  [2] =>
  string(15) "other_parameter"
}

Looks like in php 7.0 and 7.1 argv parsing is quite different, one ignores the double quotes as string delimiter and the later don't

回答2:

This message is available in a JSON formatted file named storage/framework/down generated by php artisan down command.

You can open that file and modify it.

Goodluck

This is an unrelated problem, but this was the place where Google sent me as I made this mistake... soo..

The other common reason to get:

Too many arguments, expected arguments "command".

Is that you are providing an argument, when the artisan script is expecting an option. So you need to change

./artisan yourcommand:yoursubcommand some_kind_of_input

./artisan yourcommand:yoursubcommand --an_option=some_kind_of_input

The error just generally means that artisan was not expecting an additional argument of any kind to this command...
