Laravel工匠使用带有空格的消息参数给出了太多的参数，期望的参数"command"

问题描述

我经营工匠:

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

[更新]或像@Remul建议的那样运行它:

[UPDATE] OR run it like @Remul suggested:

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

然后两者都给了我错误:

then both gives me the error:

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

如果运行命令没有这样的空格:

If run command with no spaces like this:

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

没有错误发生

推荐答案

我正在使用php 7.0.14

I am using php 7.0.14

我想通了:

问题实际上是php从命令行获取参数的方式在vendor/symfony/console/Input/ArgvInput.php中，我可以理解php会得到如下所示的错误:

Problem is actually how php is getting arguments from command lineIn 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"

因此，甚至要确保我使用以下内容制作了自己的脚本:

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

<?php

var_dump($argv);

我运行它:

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

输出为:

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"
}

我在其他装有不同版本PHP的计算机上运行它，并查看我的结果:

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"
}

像在php 7.0和7.1中argv的解析是完全不同的，人们会忽略双引号作为字符串定界符，而后面的则不会这样做

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
